Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of Internet, and particularly relates to a network resource downloading method and device, equipment and a storage medium. BACKGROUND

[0002] When a terminal downloads a resource from a server, if the distance between the terminal and the server is too far, a long network delay will be generated, which affects the download speed. In addition, in the case of insufficient bandwidth allocation or the server setting a transmission speed limit, the download will be slow or even fail. For example, when a network resource is pulled from a server in a foreign country, due to the long distance, long communication link and limited international bandwidth, the network transmission delay is high, the download speed is slow and the failure rate is high, and the bandwidth cost is also very high. Therefore, an improved network resource downloading scheme is needed to optimize the download speed in the above resource downloading scenario and reduce the network delay and the download failure rate.

Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0049] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or server including a series of steps or sub-modules does not necessarily have to be limited to those steps or sub-modules clearly listed, but can include other steps or sub-modules not clearly listed or inherent to these processes, methods, products or devices.

[0050] Before the embodiments of the present application are further described in detail, the terms and terms involved in the embodiments of the present application are explained, and the terms and terms involved in the embodiments of the present application are applicable to the following explanations.

[0051] HTTP(Hyper Text Transfer Protocol, Hyper Text Transfer Protocol): a request-response protocol that usually runs on TCP. It specifies what messages the client can send to the server and what response it gets.

[0052] CDN(Content Delivery Network, Content Delivery Network): CDN is an intelligent virtual network built on the existing network foundation. By deploying edge servers in various locations, through the load balancing, content distribution, scheduling and other function modules of the center platform, users can access the required content nearby, reduce network congestion, and improve user access response speed and hit rate.

[0053] URL(uniform resource locator, uniform resource locator): a method for specifying information location on the World Wide Web service program of the Internet.

[0054] VPN(Virtual Private Network, Virtual Private Network): a private network established on a public network for encrypted communication. It is widely used in enterprise networks. VPN gateway realizes remote access by encrypting data packets and converting data packet target addresses. VPN can be realized by servers, hardware, software and other ways.

[0055] Virtual network card: also known as virtual network adapter, which is a software simulation of a network environment and a network adapter.

[0056] Please refer to Figure 1 , Figure 1 is a schematic diagram of an application environment provided by the embodiment of the present application, as Figure 1 shown, the application environment can include at least terminal 01, first server 02, second server 03 and third server 04. In actual application, terminal 01, first server 02, second server 03 and third server 04 can be directly or indirectly connected through wired or wireless communication mode, which is not limited in the present application.

[0057] The server in the embodiment of the present application can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN(Content Delivery Network, Content Delivery Network), and basic cloud computing services such as big data and artificial intelligence platform.

[0058] Specifically, cloud technology refers to a hosting technology that unifies a series of resources such as hardware, software, and network in a wide area network or a local area network to realize data calculation, storage, processing, and sharing. It distributes computing tasks on a resource pool composed of a large number of computers, so that various application systems can obtain computing power, storage space, and information services as needed. The network that provides resources is called "cloud". Among them, artificial intelligence cloud service is also commonly referred to as AIaaS (AI as a Service). This is a mainstream service mode of an artificial intelligence platform. Specifically, the AIaaS platform will split several common AI services and provide independent or packaged services in the cloud. This service mode is similar to opening an AI theme mall: all developers can access one or more artificial intelligence services provided by the platform through API interfaces, and some experienced developers can also use the AI framework and AI infrastructure provided by the platform to deploy and maintain their own cloud artificial intelligence services.

[0059] Specifically, the server involved above can include an entity device, can specifically include a network communication submodule, a processor, a memory, and the like, and can also include software running in the entity device, and can specifically include an application and the like.

[0060] In the embodiments of the present application, the terminal 01 can include an entity device of the type of a smart phone, a desktop computer, a tablet computer, a notebook computer, a digital assistant, an augmented reality (AR) / virtual reality (VR) device, a smart voice interaction device, a smart home appliance, a smart wearable device, a vehicle-mounted terminal device, and the like, and can also include software running in the entity device, such as an application and the like.

[0061] In the embodiments of the present application, the terminal 01 can run a target application, the target application generates a resource download request for a target network resource, the terminal 01 analyzes the resource download request of the target application, and sends the obtained target resource address to the first server 02 through an address query request. In the case of receiving the address query response information carrying the backup resource address fed back by the first server 02, an updated resource download request carrying the backup resource address is generated and sent to the third server 04 to obtain the backup network resource; in the case of receiving the response information representing the absence of the backup resource address fed back by the first server 02, the resource download request is sent to the second server 03 to obtain the target network resource.

[0062] The first server 02 can be a background server in which the target resource address and the corresponding backup resource address are associated and stored, and is configured to, in response to the address query request carrying the target resource address sent by the terminal 01, perform feature recognition on the target resource address, acquire the corresponding backup resource address in a case where the category feature of the target resource address meets a preset feature condition, and send the backup resource address to the terminal 01, so that the terminal 01 sends an updated resource download request to the third server 04. The first server 02 also stores backup update time information associated with the resource address, can determine whether the backup network resource corresponding to the backup resource address is expired according to the backup update time information, and in a case where the category feature of the target resource address does not meet the preset feature condition, the associated backup resource address is not acquired, or the backup network resource is an expired resource, sends response information indicating that there is no backup resource address to the terminal 01, so that the terminal 02 sends a resource download request to the second server 03.

[0063] Specifically, the second server 03 and the third server 04 are located in different regions, and the physical distance between the second server 03 and the first server 02 is greater than the physical distance between the third server 04 and the first server 02. In addition, the physical distance between the second server 03 and the terminal 01 is greater than the physical distance between the third server 04 and the terminal 01. For example, the second server 03 can be an overseas server, and stores the target network resource. The third server 04 can be a locally deployed domestic server, such as a CDN server, and stores the backup network resource. Correspondingly, the terminal 01 sends a resource download request in the domestic area.

[0064] Specifically, the first server 02 is further configured to acquire the target network resource from the second server 03 and send the target network resource to the third server 04 for backup storage. The third server 04 stores the target network resource as a backup network resource, and sends the backup resource address of the backup network resource on the third server 04 to the first server 02. The first server 02 stores the backup resource address in association with the target resource address. In some cases, the first server 02 also acquires the update time information of the target network resource from the second server 03, and stores the update time information in association with the target resource address.

[0065] In addition, it can be understood that, Figure 1 The network resource download method shown is only an application environment, which can include more or fewer nodes, and the present application does not limit this.

[0066] The application environment or the terminal 01, the first server 02, the second server 03 and the third server 04 in the application environment involved in the embodiments of the present application can be a distributed system formed by a client, a plurality of nodes (any form of computing device in an access network, such as a server, a user terminal) connected through network communication. The distributed system can be a blockchain system, which can provide the network resource download service and the data storage service mentioned above.

[0067] Referring to Figure 10 , Figure 10 is an optional structural schematic diagram of a distributed system 100 provided by the embodiments of the present application applied to a blockchain system, formed by a plurality of nodes (any form of computing device in an access network, such as a server, a user terminal) and a client. In the distributed system, any machine such as a server, a terminal can join to become a node, and the node includes a hardware layer, an intermediate layer, an operating system layer and an application layer.

[0068] The blockchain is a new application mode of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithm, and is essentially a decentralized database, a series of data blocks associated using cryptography, each data block containing information of a batch of network transactions, for verifying the validity (anti-fake) of the information and generating the next block. The blockchain can include a blockchain underlying platform, a platform product service layer, and an application service layer. The blockchain underlying platform can include user management, basic services, smart contracts, and operation detection processing modules. The user management module is responsible for identity information management of all blockchain participants, including maintaining public and private key generation (account management), key management, and maintenance of the correspondence between real identities and blockchain addresses (permission management), and in the case of authorization, detecting and auditing the transaction of certain real identities, providing rule configuration for risk control (risk audit); the basic service module is deployed on all blockchain node devices to verify the validity of business requests and record them to the storage after consensus, for a new business request, the basic service first performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts the business information through a consensus algorithm (consensus management), and after encryption, the complete and consistent information is transmitted to the shared ledger (network communication) and recorded and stored; the smart contract module is responsible for contract registration and issuance, contract triggering and contract execution, and developers can define contract logic through a certain programming language, publish it to the blockchain (contract registration), and trigger execution according to the logic of the contract terms, complete the contract logic, and also provide contract upgrade and cancellation functions; the operation detection module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation during product release, and real-time state visualization output during product operation, such as alarm, network detection, and node device health state detection. The platform product service layer provides basic capabilities and implementation frameworks for typical applications, and developers can stack business characteristics based on these basic capabilities to complete the blockchain implementation of business logic. The application service layer provides application services based on the blockchain scheme for business participants to use.

[0069] The network resource downloading method provided in the embodiments of the present application is introduced below based on the above application environment. The embodiments of the present application can be applied to various scenarios, including but not limited to cloud technology, artificial intelligence, intelligent transportation, and assisted driving. In the scenario where the communication distance of the server storing the network resource is too far, the bandwidth allocation is insufficient, or the transmission speed limit is set, the downloading speed will be affected or the downloading will fail. For example, in the scenario of downloading game resources abroad, after the game abroad is started, the corresponding game resources or game update package needs to be pulled from the server abroad, at this time, the resources need to be pulled from the specified Internet exit through a dedicated line, thereby increasing the delay, being limited by the bandwidth of the Internet exit, and being limited by the transmission settings of the server abroad, resulting in slow downloading speed, high failure rate of downloading, high bandwidth cost and other problems. Please refer to Figure 2 , Figure 2 is a flowchart of a network resource downloading method provided in the embodiments of the present application. The present specification provides method operation steps as in the embodiments or flowcharts, but more or fewer operation steps can be included based on conventional or non-creative labor. The order of the steps listed in the embodiments is only one of the many execution orders of the steps, and does not represent the only execution order. In actual system or server product execution, the method order shown in the embodiments or the drawings can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment). Specifically, as shown in Figure 2 , the method can include the following steps.

[0070] S201: The terminal parses the resource downloading request to obtain the target resource address in response to the resource downloading request for the target network resource sent by the target application program.

[0071] In the embodiments of the present application, the target resource address is a network address of the target network resource in the second server, representing a storage location of the target network resource in the second server, and the second server can be a source station storing the target network resource. The third server provides backup storage service of the target network resource, that is, stores the backup network resource corresponding to the resource download request. The physical locations of the second server and the third server are located in different regions, for example, the second server is an overseas server and the third server is a domestic server, and the physical distance between the second server and the first server is greater than the physical distance between the third server and the first server. Correspondingly, the physical distance between the second server and the terminal is greater than the physical distance between the third server and the terminal. For example, the first server is a background server, the second server is an overseas server, the communication physical link between the first server and the terminal is long, or needs to communicate through a specified Internet exit, the network delay is long, the download speed is slow, and the bandwidth is limited, resulting in unstable data transmission and easy download failure; the third server can be a domestic server, which is deployed near the terminal, for example, a CND server, etc., the communication physical distance between the first server and the terminal is short, the bandwidth limitation is less and the bandwidth cost is low, the communication is stable, and the transmission speed is fast.

[0072] In the embodiments of the present application, the target application program is an application program with a specified package name, which can be a game application program, for example, a specified overseas game application program. When the target application program needs to download an update resource package or an update installation package or other target network resource, a resource download request carrying the target resource address of the target network resource will be generated. When the terminal detects that the target application program sends the resource download request, it will be intercepted and parsed to obtain the target resource address. Specifically, the target resource address can be a URL address.

[0073] In actual application, before S201, the method can further include the following steps.

[0074] S101: Start a virtual private network service.

[0075] S103: Intercept the resource download request sent by the target application program through the virtual private network service.

[0076] Specifically, the virtual private network service can be started by using a download processing program (such as an accelerator). The virtual private network service can be a VPN service pre-set in the terminal, which can intercept traffic with a specified package name. By using the virtual private network service, all network requests sent by the target application program with a specified package name are intercepted through a virtual network card to realize subsequent parsing processing.

[0077] In some cases, the virtual private network service can also be replaced by using a hook method to intercept the resource download request of the target application program and obtain the target resource address.

[0078] In actual application, S201 can specifically include the following steps.

[0079] S2011: structurally analyzing the network layer packet of the resource download request to obtain protocol information and a transport layer packet of the resource download request.

[0080] S2013: analyzing the transport layer packet according to the protocol information to obtain request data of the resource download request.

[0081] S2015: obtaining the target resource address from a request header of the request data.

[0082] Specifically, when the resource download request sent by the target application program is intercepted, the network layer packet of the resource download request can be obtained through the control information corresponding to the resource download request in the virtual network service. By analyzing the structure of the network layer packet, the protocol used by the upper layer can be determined according to the protocol field in the network layer data structure field, that is, the protocol information is obtained, and the transport layer packet is obtained. Based on the protocol information, the structure of the transport layer packet is further analyzed, the request data is obtained, and the target resource address is obtained from the address field of the request header of the request data.

[0083] Specifically, the control information can be a file handle (fd) of the virtual private network service, the network layer packet can be an IP packet, correspondingly, the transport layer packet can be a TCP packet, the request data can be HTTP data, and the URL address of the resource download request is included in the request header of the HTTP data. In an embodiment, please refer to Figure 3 , the URL address obtaining process can specifically be: the resource download request of the target application program is intercepted by the virtual gateway; the IP packet is obtained from the fd in the virtual network card by the download processing program (such as the accelerator), the TCP packet is obtained by analyzing the IP packet, and the URL in the HTTP data is obtained by analyzing the TCP packet.

[0084] S203: the terminal sends an address query request carrying the target resource address to the first server.

[0085] In the embodiment of the application, after obtaining the target resource address, the terminal delays sending the resource download request to the second server, generates an address query request carrying the target resource address, and sends the address query request to the first server.

[0086] S205: after receiving the address query request carrying the target resource address sent by the terminal, the first server performs category feature recognition on the target resource address.

[0087] In the embodiments of the present application, the first server is a background server of the terminal and is provided with an address cache database for storing resource addresses satisfying preset characteristic conditions and corresponding backup resource addresses. The first server responds to an address query request to perform category characteristic identification on a target resource address to obtain corresponding category characteristics, and then judges whether the category characteristics satisfy preset characteristic conditions. The category characteristics can include, but are not limited to, domain name category characteristics and data file format characteristics of the target resource address. In some embodiments, after receiving the target resource address, the domain name field and the file format field in the target resource address are identified, the identified domain name field is matched with a preset domain name, and the identified file format field is matched with a preset file format. If the corresponding preset domain name and preset file format are matched, it is determined that the category characteristics of the target resource address satisfy the preset characteristic conditions. If any of them is not matched, the category characteristics of the target resource address do not satisfy the preset characteristic conditions. For example, the target resource address is a URL address, and the target application program is a game application program. The first server responds to the address query request to identify the game domain name field and the resource format suffix field in the URL address. The resource format suffix field represents the file format of the target network resource. If the game domain name field is matched with an overseas game domain name and the resource format suffix field is matched with file formats such as exe and dat, it is determined that the category characteristics of the URL address satisfy the preset characteristic conditions.

[0088] S207: The first server acquires the backup resource address stored in association with the target resource address in a case where it is identified that the category characteristics of the target resource address satisfy the preset characteristic conditions.

[0089] In the embodiments of the present application, the backup resource address is a network address of a backup network resource corresponding to the target network resource in the third server, representing the storage location of the backup network resource in the third server. The backup resource address is stored in association with the target resource address. In a case where the preset characteristic conditions are satisfied, the backup resource address is searched. Specifically, the backup resource address stored in association with the target resource address is searched from the address cache database, which can be searched by taking the target resource address as a key. In a case where it is found that the corresponding backup resource address exists, it is indicated that the backup network resource of the target network resource in the second server has been stored in the third server.

[0090] S209: The first server sends address query response information corresponding to the address query request to the terminal, and the address query response information carries the backup resource address stored in association with the target resource address.

[0091] In the embodiments of the present application, the first server responds to the address query request to send corresponding address response information to the terminal, and the address response information carries the found backup resource address.

[0092] S211: After the terminal receives the address query response information corresponding to the address query request sent by the first server, the terminal updates the target resource address in the resource download request to the backup resource address, and obtains an updated resource download request.

[0093] S213: The terminal sends the updated resource download request to the third server, and obtains the backup network resource sent by the third server.

[0094] In the embodiment of the application, after the terminal receives the backup resource address, the terminal replaces the target resource address in the request data of the resource download request with the backup resource address, and obtains updated request data. Then, the terminal encapsulates the updated request data based on the aforementioned protocol information, obtains an updated transport layer data packet, encapsulates the updated transport layer data packet into an updated network layer data packet, and finally obtains an updated resource download request and a corresponding request data packet, and sends the updated resource download request and the corresponding request data packet to the third server, so that the third server finds and feeds back the backup network resource corresponding to the backup resource address in response to the updated resource download request. For example, the resource download request is a game resource download request sent by a game application program to an overseas game network resource. After the download processing program receives the backup resource address cached in the domestic from the first server, the download processing program updates the game resource download request sent by the game application program, replaces the game url and host in the http data of the game resource download request with the backup resource address, and then generates an updated TCP data packet, encapsulates the updated TCP data packet into an updated IP data packet, and finally obtains an updated game resource download request, and sends the updated game resource download request to the third server (a domestic server) through a real network card. After the third server receives the request, the third server feeds back the stored backup network resource to the game application program in response to the request.

[0095] Based on the above technical solution, the resource download request sent to the second server is converted into a request sent to the third server, so that the backup resource is downloaded from the third server with shorter communication distance and link, which can effectively reduce network delay, improve resource download speed, stability and success rate, and save bandwidth occupation and cost of the specified Internet exit.

[0096] In the embodiment of the application, the method further includes the following steps.

[0097] S215: The first server sends response information indicating that there is no backup resource address to the terminal in a case where the first server identifies that the category feature of the target resource address does not satisfy the preset feature condition or the first server fails to obtain the associated backup resource address.

[0098] In actual application, the response information can carry an identification code indicating that there is no backup resource address.

[0099] S217: In a case where the terminal receives the response information sent by the first server and representing that there is no backup resource address, the terminal sends a resource download request to the second server to obtain the target network resource from the second server.

[0100] In actual applications, for a target resource address that cannot find a cached backup resource address or a non-designated category feature, after receiving the response information returned by the first server, the download processing program restores the original resource download request to a network layer data packet, and then sends it to the second server through a real network card, so that the second server feeds back the target network resource to the terminal.

[0101] S219: In a case where the first server identifies that the category feature of the target resource address meets the preset feature condition and has not obtained the associated backup resource address, the first server sends a corresponding resource download request to the second server based on the target resource address to obtain the target network resource from the second server.

[0102] In actual applications, if the category feature of the target resource address meets the preset feature condition, but the first server cache does not store the backup resource address corresponding to the target resource address, it indicates that the resource download request is a primary request for the target network resource. The first server sends a resource download request carrying the target resource address to the second server, so that the second server sends the target network resource to the first server.

[0103] S221: The first server sends the target network resource to the third server, so that the third server stores the target network resource as a corresponding backup network resource, and sends the backup resource address of the backup network resource to the first server.

[0104] S223: The first server receives the backup resource address sent by the third server and stores the target resource address and the backup resource address in association.

[0105] In actual applications, after receiving the target network resource, the first server sends it to the third server for backup storage to generate a corresponding backup network resource, which can reduce the storage pressure of the first server and avoid affecting the processing speed. After the third server stores the backup network resource, it sends the backup resource address to the first server, and the first server builds an association between the target resource address and the backup resource address for associated storage. In this way, when the address query request carrying the target resource address is received again, the backup resource address is fed back to the terminal, so that the terminal downloads the resource from the third server, improves the download speed and stability, and saves the designated Internet export bandwidth.

[0106] Based on the above part or all of the embodiments, please refer to Figure 4The embodiment of the present application provides another network resource downloading method, comprising the following steps.

[0107] S301: The terminal analyzes the resource downloading request to obtain the target resource address in response to the resource downloading request for the target network resource sent by the target application program.

[0108] S303: The terminal sends an address query request carrying the target resource address to the first server.

[0109] S305: The first server performs category feature identification on the target resource address after receiving the address query request carrying the target resource address sent by the terminal.

[0110] S307: The first server acquires the backup resource address stored in association with the target resource address in the case that the category feature of the target resource address meets the preset feature condition.

[0111] It can be understood that the steps S301-S307 are similar to the specific implementation of the foregoing steps S201-S207, and thus will not be described here again.

[0112] S309: The first server acquires the backup update time information of the backup network resource stored in association with the target resource address.

[0113] In the embodiment of the present application, the address cache database of the first server also stores the backup update time information corresponding to the target resource address, and the backup update time information represents the last modification time of the network resource stored in the second server and corresponding to the backup network resource. The backup update time information is the modification time information carried by the second server when the second server feeds back the network resource when the first server requests the corresponding network resource from the second server for the first time. Specifically, the backup update time information can be a Last-Modified field.

[0114] S311: The first server sends a time information query request carrying the target resource address to the second server.

[0115] S313: The first server receives the time query response information corresponding to the time information query request sent by the second server, and the time query response information carries the update time information of the target network resource.

[0116] In the embodiment of the present application, the target network resource of the second server can have an updated version, and the backup resource address in the first server and the backup network resource stored in the third server can not be the current updated version. The first server sends a time information query request to the second server, so that the second server obtains the update time information of the corresponding target network resource based on the target resource address, generates network response information carrying the update time information of the target network resource, and then sends it to the first server. The update time information of the target network resource sent by the second server represents the last modification time of the latest version of the target network resource.

[0117] S315: In the case that the backup update time information is consistent with the update time information of the target network resource, the first server sends the address query response information corresponding to the address query request to the terminal, and the address query response information carries the backup resource address associated with the target resource address.

[0118] In the embodiment of the present application, the first server compares the backup update time information with the update time information of the target network resource. If they are consistent, it is determined that the backup network resource stored in the third server is not expired, and the sending step of the address query response information is triggered.

[0119] S317: After receiving the backup resource address corresponding to the target resource address sent by the first server, the terminal updates the target resource address in the resource download request to the backup resource address, and obtains an updated resource download request.

[0120] S319: The terminal sends the updated resource download request to the third server, and obtains the backup network resource sent by the third server.

[0121] It can be understood that S315-S319 are similar to the specific embodiments of the foregoing S209-S213, and will not be described here.

[0122] S321: In the case that the backup update time information is inconsistent with the update time information of the target network resource, it is determined that the backup network resource corresponding to the backup resource address is an expired resource.

[0123] In the embodiment of the present application, if they are inconsistent, it indicates that the version of the target network resource in the second server is inconsistent with the version of the backup network resource. If the update time of the target network resource is later than the backup update time, that is, the target network resource has an updated version, it is determined that the backup network resource stored in the third server is an expired resource, and then steps S323 and S327 are triggered.

[0124] S323: The first server sends response information indicating that there is no backup resource address to the terminal in a case where it is identified that the category feature of the target resource address does not satisfy the preset feature condition, the associated backup resource address is not acquired, or the backup network resource corresponding to the backup resource address is an expired resource.

[0125] S325: The terminal sends a resource download request to the second server to acquire the target network resource from the second server in a case where it receives the response information indicating that there is no backup resource address sent by the first server.

[0126] S327: The first server sends a corresponding resource download request to the second server based on the target resource address to acquire the target network resource and the corresponding update time information from the second server in a case where it is identified that the category feature of the target resource address satisfies the preset feature condition and the associated backup resource address is not acquired or the backup network resource corresponding to the backup resource address is an expired resource.

[0127] S329: The first server sends the target network resource to the third server to enable the third server to store the target network resource as a corresponding backup network resource and send the backup resource address of the backup network resource to the first server.

[0128] S331: The first server stores the target resource address, the backup resource address, and the corresponding update time information in association after receiving the backup resource address sent by the third server.

[0129] It can be understood that S323-S325 are similar to the specific implementation manners of the foregoing S215-S217, and S329-S333 are similar to the specific implementation manners of the foregoing S221-S225, which will not be described herein again.

[0130] In the embodiments of the present application, if the category feature of the target resource address meets the preset feature condition, it is determined that the target network resource needs to be backup stored. At this time, if the backup resource address corresponding to the target resource address and the backup update time information are not stored in the first server cache, i.e., the backup resource address cannot be found, it indicates that the resource download request is a first request for the target network resource; or if the backup network resource corresponding to the backup resource address is an expired resource, it indicates that the backup resource address and the backup update time stored in the first server cache and the backup network resource stored in the third server need to be updated. Correspondingly, the first server sends a resource download request carrying the target resource address to the second server, so that the second server sends the target network resource and the corresponding update time information to the first server. After receiving the target network resource, the first server sends it to the third server for storage. After the third server stores the target network resource to generate the backup network resource, it sends the corresponding backup resource address to the first server. The first server constructs the association relationship among the target resource address, the backup resource address, and the update time information for associated storage. It can be understood that the update time information associated and stored here is the backup update time information mentioned above.

[0131] It should be noted that the first server can periodically send a corresponding time information query request to the second server based on the cached target resource addresses, to obtain the latest update time information. In the case of inconsistent time information, the backup resource address, the backup update time information, and the backup network resource are periodically updated based on the above S327-S335.

[0132] Based on the above scheme, not only can the network delay be effectively reduced, the resource download speed, stability and success rate be improved, but also the bandwidth occupation and cost of the specified Internet exit can be saved, and the terminal from downloading expired resources and preventing download accidents can be avoided.

[0133] In some embodiments, due to the communication limitations and instability between the terminal and the second server, during the process of the terminal pulling the target network resource from the second server, the download time may be too long or the download may fail. Correspondingly, after S327, the method can further include step S337: the terminal sends a backup resource download request carrying the backup resource address to the third server to obtain the backup network resource corresponding to the backup resource address from the third server in the case that the transmission time length of the target network resource exceeds the preset time length and / or the download fails. In this way, in the case that the latest target network resource cannot be obtained, the old version of the backup network resource is used for resource substitution, the resource service is provided in the case that the user is unaware, and the user experience is significantly improved.

[0134] The network resource downloading method provided in the application can solve the problems of high network resource failure rate and slow downloading speed, especially in the scenario of large file downloading, and can improve the downloading speed and success rate, save international bandwidth, and reduce resource downloading cost.

[0135] The network resource downloading method provided in the application is introduced below based on the above application environment, and is applied to a terminal.
