[0069] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0070] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0071] Currently, in browsers, downloading files is an important function of the browser and a scenario that users use frequently. The existing file download method usually downloads files separately through the browser's network process, and the download speed is limited. However, with the development of the Internet, the quality of video and film information has also been greatly improved, and the size of files has also become larger. Therefore, the existing file download method has the defects of slow download speed and poor user experience.

[0072] Therefore, in order to overcome the above-mentioned defects, the present application provides a solution, which includes: responding to a file download request, determining the file to be downloaded corresponding to the file download request, calling a download acceleration plug-in built into the browser, wherein the download acceleration plug-in is an independent process relative to the browser, downloading the file to be downloaded through the download acceleration plug-in, and obtaining the download completion file; since the present application downloads the file by calling the download acceleration plug-in built into the browser, the download acceleration plug-in is an independent process relative to the browser, thereby being able to increase the file download speed and thus improve the user experience.

[0073] It should be noted that the execution subject of this embodiment can be a file downloading device with data processing, network communication and program running functions, such as a computer, or other electronic devices that can achieve the same or similar functions, and this embodiment does not impose any restrictions on this.

[0074] Based on this, the present application embodiment provides a file download method, referring to Figure 1 , Figure 1 This is a flowchart of the first embodiment of the method for downloading documents of this application.

[0075] In a first embodiment, the file downloading method includes:

[0076] Step S10: In response to a file download request, determining a file to be downloaded corresponding to the file download request.

[0077] It should be understood that in order to clarify the specific file that the user wants to download and provide a target for subsequent download operations. In this embodiment, in response to a file download request, a file to be downloaded corresponding to the file download request is determined. The file download request may refer to a file request initiated by a user through a browser to obtain and save the file locally from the network. The file to be downloaded may refer to a specific file specified in the file download request that needs to be obtained from the network.

[0078] In a specific implementation, when a user clicks a download link through a browser, a file download request is issued, and the browser can respond to the file download request and parse out a Uniform Resource Locator (URL) of the file to be downloaded specified in the file download request.

[0079] Step S20: calling a download acceleration plug-in built into the browser, wherein the download acceleration plug-in is an independent process relative to the browser.

[0080] It is understandable that in order to increase the download speed and reduce the coupling with the main process of the browser, the stability and response speed of the browser are improved. In this embodiment, the built-in download acceleration plug-in of the browser is called for downloading. Among them, the download acceleration plug-in may refer to a software component that is integrated or can be integrated into the browser, which is intended to improve the speed and efficiency of file downloads. In this embodiment, the download acceleration plug-in may refer to an independent process relative to the main process of the browser. An independent process may refer to an independently running program instance in a computer operating system, which has its own memory space and system resources and is relatively isolated from other processes. In this embodiment, the download acceleration plug-in runs as an independent process, which can reduce the coupling with the main process of the browser.

[0081] In the specific implementation, after determining the file to be downloaded, the browser can decide whether to call the built-in download acceleration plug-in to handle the download task according to the configuration or user selection. This plug-in runs as an independent process and is relatively isolated from the main browser process.

[0082] Furthermore, in order to achieve low-coupling communication between the browser and the download acceleration plug-in and improve the flexibility and scalability of the system, the step S20 includes: generating a download task corresponding to the file to be downloaded; and calling the download acceleration plug-in built into the browser through a remote procedure call mechanism based on the download task. The download task may refer to a task entity generated according to a file download request, including information about the file to be downloaded (such as URL, file name, expected size, etc.) and download operation related parameters (such as download path, whether to use acceleration, etc.). Remote Procedure Call (RPC) may refer to a protocol that allows a program (browser) to call a procedure or function in another address space.

[0083] In the specific implementation, the browser generates a download task based on the parsed URL of the file to be downloaded and the user's download preferences (such as download path, whether to use acceleration, etc.). If the download task specifies the use of an acceleration plug-in or the file size of the file to be downloaded is larger than the preset threshold, the browser can call the built-in download acceleration plug-in through the RPC mechanism. This plug-in runs as an independent process and is relatively isolated from the main browser process.

[0084] Step S30: downloading the file to be downloaded through the download acceleration plug-in to obtain a download completion file.

[0085] It should be understood that in order to utilize the efficient downloading capability of the download acceleration plug-in and quickly obtain a complete download completion file, in this embodiment, the download acceleration plug-in is used to download the file to be downloaded to obtain the download completion file, wherein the download completion file may refer to a complete file formed after all the data blocks to be downloaded are successfully downloaded and correctly assembled.

[0086] In a specific implementation, after receiving the download task, the download acceleration plug-in can start to execute the download operation. The specific download operation may include steps such as establishing a network connection, sending an HTTP request, receiving a server response, and saving the file locally, which is not limited in this embodiment.

[0087] Furthermore, in order to facilitate the user to understand the download result, after step S30, the process further includes: receiving the download result sent back by the download acceleration plug-in through a remote procedure call message; and displaying the download result on the user interaction interface of the browser. The download result may refer to the general term for information such as whether the download is successful, the file size, and the download speed, which is sent back to the browser through an RPC message after the download acceleration plug-in completes the file download.

[0088] In a specific implementation, after the download acceleration plug-in completes the download task, it can send the download result (such as success, file size, download speed, etc.) back to the browser through an RPC message. After receiving the download result sent back by the download acceleration plug-in, the browser can display it on the browser's user interface (such as the download manager, status bar, etc.).

[0089] This embodiment downloads files by calling a download acceleration plug-in built into the browser. The download acceleration plug-in is an independent process relative to the browser, thereby increasing the file download speed and further improving the user experience.

[0090] Reference Figure 2 , Figure 2 This is a flow chart of the second embodiment of the method for downloading application files. Figure 1 The first embodiment shown proposes a second embodiment of the method for downloading files of the present application.

[0091] In the second embodiment, before step S20, the method further includes:

[0092] Step S11: pre-parse the file to be downloaded to obtain the file size of the file to be downloaded.

[0093] Accordingly, the step S20 includes:

[0094] Step S20': If the file size is larger than a preset threshold, a download acceleration plug-in built into the browser is called.

[0095] It should be understood that in order to accurately determine whether it is necessary to call a download acceleration plug-in for download acceleration, this embodiment will pre-parse the file to be downloaded before calling the built-in download acceleration plug-in of the browser to obtain the file size of the file to be downloaded. If the file size is greater than a preset threshold, the built-in download acceleration plug-in of the browser is called. Among them, pre-parsing can refer to the process of preliminarily parsing the relevant information of the file (such as file size, type, server address, etc.) before officially downloading the file. The file size can refer to the actual data size of the file to be downloaded, which can be in bytes. The preset threshold can be a pre-set value used to determine whether the file to be downloaded needs to be downloaded using a download acceleration plug-in. If the file size exceeds this threshold, the acceleration plug-in is called.

[0096] In the specific implementation, before officially downloading the file, the browser can send an HTTP HEAD request to the server. This request will not download the content of the file, but only obtain the file's metadata (such as file size, type, etc.). The browser can determine whether the size of the file to be downloaded exceeds the preset threshold (such as 10MB). If it exceeds this threshold, the built-in download acceleration plug-in will be called to download the file.

[0097] Furthermore, in order to improve the accuracy of pre-analysis, the step S11 includes: parsing the file to be downloaded to obtain the uniform resource locator of the file to be downloaded; converting the uniform resource locator into an Internet Protocol address through the network process of the browser; and requesting the file size of the file to be downloaded from the server corresponding to the Internet Protocol address through the network process of the browser. Among them, the uniform resource locator (Uniform Resource Locator, URL) can be used to identify the address of a resource on the network. In a specific implementation, the URL can be a string containing information such as a protocol, domain name, and path. Internet Protocol Address (Internet Protocol Address, IP Address): A digital label used to identify a device or server on a network.

[0098] In a specific implementation, when a user clicks a download link in a browser, the browser can parse the download link clicked by the user and extract the URL of the file to be downloaded. The browser converts the domain name in the URL into the corresponding IP address through DNS resolution. Based on the IP address, the browser sends an HTTP HEAD request to the server to obtain the file's metadata (such as file size) without downloading the file content.

[0099] Furthermore, for small files, using the network process of the browser can simplify the download process and improve the download efficiency. After step S11, it also includes: if the file size is less than or equal to a preset threshold, calling the network process of the browser; downloading the file to be downloaded through the network process of the browser to obtain a downloaded file. The network process of the browser may refer to a component in the browser that is responsible for processing network communications (such as HTTP requests and responses).

[0100] In a specific implementation, the browser can determine whether the file size meets the condition according to a preset threshold (such as 10MB). If the file size is less than or equal to the preset threshold, the browser's network process is used for downloading. After deciding to use the browser's network process to download the file, the browser can send a formal download request to the server, and receive and save the file data through the network process.

[0101] For ease of understanding, refer to Figure 3 This invention is provided for illustration, but is not intended to limit the present application. Figure 3 This is a specific flow chart of an embodiment of the method for downloading application documents. Figure 3 In the method for downloading a file, the method comprises the following steps:

[0102] 1. The user clicks on the download link: When a user visits a website, he clicks on an HTTP link that can be downloaded.

[0103] 2. The browser parses the URL address and obtains the file size: The browser can parse the URL of this link and pass the URL to the browser's network process through inter-process communication. The network process performs pre-parsing, including DNS resolution and request sending. After the server responds, it will return file information including the file size.

[0104] 3. Determine whether the file size is greater than the preset threshold: Determine whether the file size is greater than 10M.

[0105] 4. If the file size is not greater than the preset threshold, continue to download the file through the browser's network process.

[0106] 5. If the file size is larger than the preset threshold, the browser's built-in download acceleration plug-in is called: In order to reduce program coupling, the download acceleration plug-in is taken out separately as an independent process.

[0107] 6. Download files through the download acceleration plug-in: The interaction between the browser and the download acceleration plug-in is implemented through RPC.

[0108] 7. Return download results: If the download acceleration plug-in completes the download of the file, it can return the result to the browser through the RPC message.

[0109] Before calling the built-in download acceleration plug-in of the browser, this embodiment will pre-parse the file to be downloaded to obtain the file size of the file to be downloaded. If the file size is greater than a preset threshold, the built-in download acceleration plug-in of the browser will be called, so as to accurately determine whether it is necessary to call the download acceleration plug-in for download acceleration, thereby avoiding waste of resources.

[0110] Reference Figure 4 , Figure 4 This is a flow chart of the third embodiment of the method for downloading files of the present application. Based on the above embodiments, the third embodiment of the method for downloading files of the present application is proposed.

[0111] In the third embodiment, the step S30 includes:

[0112] Step S301: Obtain the file type of the file to be downloaded.

[0113] It should be understood that in order to further improve the file download speed, in this embodiment, the file type of the file to be downloaded is also obtained, and the most suitable download method is selected based on the file type to download the file. The file type may refer to the type or format of the file, such as Hypertext Transfer Protocol (HTTP) type files, BitTorrent type files, etc., which are not limited in this embodiment.

[0114] Step S302: based on the file type, download the file to be downloaded through the download acceleration plug-in to obtain a download completion file.

[0115] In a specific implementation, during the download process, the browser or the download acceleration plug-in can obtain the file type of the file to be downloaded by analyzing the file extension or Multipurpose Internet Mail Extensions (MIME) type. According to the obtained file type information, the download acceleration plug-in can select the most suitable download method to download the file to be downloaded.

[0116] This embodiment obtains the file type of the file to be downloaded and selects the most suitable downloading method to download the file based on the file type, thereby further improving the file download speed.

[0117] Furthermore, in order to improve the download speed of HTTP type files, the step S302 includes: if the file type is a hypertext transfer protocol type, dividing the data to be downloaded corresponding to the file to be downloaded into a first data block and a second data block; downloading the first data block from the original download site corresponding to the file to be downloaded through the original acceleration node cluster; downloading the second data block from other data sources through the intelligent acceleration node cluster, wherein the other data sources are data sources other than the original download site; assembling the first data block and the second data block to obtain a downloaded file.

[0118] It should be noted that the data to be downloaded may refer to all data contents contained in the file to be downloaded, and these data may be divided into multiple data blocks during the download process for easy transmission and processing. The first data block may refer to the first part of the data to be downloaded after being divided, and the first data block may include multiple data blocks. The second data block may refer to the second part of the data to be downloaded after being divided, and together with the first data block, it constitutes a complete file to be downloaded, and the second data block may also include multiple data blocks. The original acceleration node cluster may refer to a group of servers or nodes specifically used to obtain data from the original download site. The original download site may be the original server or site that provides the file to be downloaded. The intelligent acceleration node cluster may refer to a group of servers or nodes that can intelligently select the optimal download path according to network conditions and data sources. Other data sources may be any source that can provide the file data to be downloaded except the original download site, such as a peer-to-peer (P2P) network, a content delivery network (CDN) node, a local memory, etc., and this embodiment does not limit this.

[0119] In a specific implementation, if the file type is an HTTP type, the data to be downloaded can be divided into multiple data blocks according to factors such as the file size, network conditions, and download strategies (such as dividing the file into multiple data blocks according to the size of 1M), and then the multiple data blocks can be divided into a first data block and a second data block according to a preset strategy. Among them, the preset strategy can be set in advance, and this embodiment does not limit this. An HTTP request is sent to the original download site through the server or node of the original acceleration node cluster, and the first data block is downloaded from the original download site. Utilizing the intelligent selection capability of the intelligent acceleration node cluster, the second data block is requested and downloaded from other data sources other than the original download site (such as other users in the P2P network, CDN nodes, etc.). After the first data block and the second data block are downloaded, the first data block and the second data block can be reassembled in the original order of the files to form a complete download completion file.

[0120] Furthermore, in order to achieve dynamic optimization and improve the download speed, the downloading of the second data block from other data sources through the intelligent acceleration node cluster includes: selecting a download acceleration method through the intelligent acceleration node cluster, wherein the download acceleration method includes at least one of peer-to-peer network acceleration, content distribution network acceleration and mirror acceleration; downloading the second data block from the corresponding data source based on the download acceleration method.

[0121] It should be understood that in order to achieve dynamic optimization and improve download speed, in this embodiment, the intelligent acceleration node cluster can intelligently select the download acceleration method, and request and download the second data block from the corresponding data source according to the download acceleration method selected by the intelligent acceleration node cluster.

[0122] It should be noted that peer-to-peer acceleration (P2P acceleration) may refer to a technology that uses the downloaded data of other users in the network to accelerate the download process. Content distribution network acceleration (CDN acceleration) may refer to a technology that accelerates content distribution and downloading through CDN nodes distributed in various places. Mirror acceleration may refer to a technology that uses a mirror server that stores the same file to accelerate downloading.

[0123] In the specific implementation, the intelligent acceleration node cluster intelligently selects the optimal download acceleration method based on factors such as current network conditions, availability of data sources, and load conditions.

[0124] It is understandable that in order to fully utilize the advantages of various acceleration methods and improve the download speed, in this embodiment, the second data block is downloaded from the corresponding data source based on the download acceleration method. In a specific implementation, for example, according to the download acceleration method selected by the intelligent acceleration node cluster, the second data block is requested and downloaded from the corresponding data source.

[0125] Furthermore, in order to utilize the resources of other users in the network to accelerate downloading and reduce the dependence on the original server and bandwidth consumption, the download acceleration method is peer-to-peer network acceleration; the downloading of the second data block from the corresponding data source based on the download acceleration method includes: obtaining the current download data of each node in the peer-to-peer network, and matching the data to be downloaded with the current download data of each node; selecting a peer node from the peer network according to the matching result, and downloading the first data block through the peer node. Wherein, the peer node may refer to a node that provides data to other users in peer-to-peer network acceleration.

[0126] In a specific implementation, if a certain peer node has downloaded a portion of the data of the second data block, the smart acceleration node cluster can guide other users to download this portion of data from the peer node.

[0127] Furthermore, in order to utilize the distributed characteristics of the CDN network to improve the download speed, the download acceleration method is content distribution network acceleration; the downloading of the second data block from the corresponding data source based on the download acceleration method includes: requesting a content distribution network acceleration node; downloading the second data block through the content distribution network acceleration node. The content distribution network acceleration node may refer to a specific server node in the CDN network, which is responsible for storing and distributing content.

[0128] Furthermore, in order to maintain the smoothness of the CDN download process, the request for the content distribution network acceleration node includes: creating an independent thread, and requesting the content distribution network node information corresponding to the file to be downloaded from the content distribution network service through the independent thread; and selecting a content distribution network node based on the content distribution network node information.

[0129] It should be understood that in order to maintain the smoothness of the CDN download process, in this embodiment, an independent thread can be created and CDN download can be performed through the independent thread. The independent thread can refer to a thread in a computer program that can independently execute tasks, which does not share the execution path with the main thread or other threads, but can share the resources of the process.

[0130] It is understandable that after the independent thread is created, the independent thread is responsible for selecting a CDN node from the CDN network and downloading the second data block through the CDN node. The process of selecting a CDN node can be based on a variety of factors, such as the availability of the node, the download speed, the geographical location, and the distance from the user, etc., which are not limited in this embodiment. Among them, the content distribution network service can be a system that provides a content distribution network (CDN) acceleration service, which realizes rapid distribution and transmission of data by deploying multiple nodes. Content distribution network node information can refer to detailed information about each node in the content distribution network, including the address, status, load, etc. of the node.

[0131] Furthermore, in order to utilize the fast data access provided by the mirror server to increase the download speed, the download acceleration method is mirror acceleration; the downloading of the second data block from the corresponding data source based on the download acceleration method includes: searching in the backend service whether there is a target file identical to the file to be downloaded; obtaining the mirror address of the target file, and downloading the second data block through the mirror address. Among them, mirror acceleration may refer to accelerating the download using a mirror server with the same content as the original server, and the mirror server may be located in a different geographical location to provide faster data access speed. The target file may refer to a file with the same content as the file to be downloaded, and may be located on a mirror server or other storage location. The mirror address may point to the URL or network location of the target file, and is used to download data from the mirror server.

[0132] In a specific implementation, it is searched in the backend service whether there is a target file identical to the file to be downloaded, the mirror address of the target file is obtained, and the second data block is downloaded from the mirror server through the mirror address.

[0133] It should be understood that in order to further improve the download speed, in this embodiment, the download acceleration method may include peer-to-peer network acceleration, content distribution network acceleration and mirror acceleration, then the downloading of the second data block from the corresponding data source based on the download acceleration method includes: accelerating the download of the first part of the data blocks in the second data block through the peer-to-peer network, accelerating the download of the second part of the data blocks in the second data block through the content distribution network, and accelerating the download of the third part of the data blocks in the second data block through the mirror. The specific download process of each acceleration method is as described above and will not be repeated here.

[0134] Furthermore, in order to improve the download speed of BitTorrent type files, the downloading of the file to be downloaded through the download acceleration plug-in based on the file type to obtain the download completion file includes: if the file type is a bitstream file type, dividing the data to be downloaded corresponding to the file to be downloaded into a first data block and a second data block; downloading the first data block through a bitstream seed cluster, and downloading the second data block through a content distribution network acceleration node cluster; assembling the first data block and the second data block to obtain the download completion file.

[0135] It should be noted that the data to be downloaded may refer to all data contents contained in the file to be downloaded, and these data may be divided into multiple data blocks during the download process for easy transmission and processing. The first data block may refer to the first part of the data to be downloaded after being divided, and the first data block may include multiple data blocks. The second data block may refer to the second part of the data to be downloaded after being divided, and together with the first data block, it constitutes a complete file to be downloaded, and the second data block may also include multiple data blocks.

[0136] In a specific implementation, if the file type is a BitTorrent type, the data to be downloaded can be divided into multiple data blocks based on factors such as the file size, network conditions, and download strategy, and then the multiple data blocks can be divided into a first data block and a second data block based on the peer node information of the bittorrent seed cluster and the content distribution network node information of the content distribution network acceleration node cluster.

[0137] It is understandable that in order to make full use of the advantages of the two technologies, an efficient and stable file download service is achieved. In this embodiment, the first data block is downloaded through a bitstream seed cluster, and the second data block is downloaded through a content distribution network acceleration node cluster. Among them, the bitstream seed cluster may refer to a distributed download network based on the BitTorrent protocol, which is composed of multiple nodes, and these nodes jointly provide a piecemeal download service for the file. Each node has a portion of the data of the file and can share this data with other nodes. The content distribution network acceleration node cluster may refer to a distributed network architecture, consisting of multiple geographically dispersed nodes. These nodes cache the content of the original server and distribute the content to the node closest to the user based on the user's geographical location and network conditions to improve download speed and user experience.

[0138] In the specific implementation, the first data block is downloaded through the BitTorrent seed cluster, because the BitTorrent protocol is suitable for distributed download of large-scale files and can make full use of idle resources in the network. For the second data block, the CDN acceleration node cluster is used to download, because CDN can significantly increase the download speed and reduce latency, especially for large-volume, high-concurrency download scenarios.

[0139] It should be understood that in order to ensure the integrity and correctness of the file, in this embodiment, the first data block and the second data block are assembled to obtain a download completion file, wherein the download completion file may refer to a complete file formed after all the data blocks to be downloaded are successfully downloaded and correctly assembled.

[0140] In a specific implementation, after the first data block and the second data block are downloaded, the first data block and the second data block can be reassembled according to the original order of the file to form a complete download completed file.

[0141] Furthermore, in order to improve the download speed of the data block, the downloading of the first data block through the bitstream seed cluster and the downloading of the second data block through the content distribution network acceleration node cluster include: selecting a peer node from the bitstream seed cluster and downloading the first data block through the peer node; selecting a content distribution network node from the content distribution network acceleration node cluster, and downloading the second data block through the content distribution network node.

[0142] It should be noted that a peer node may refer to a node in a bittorrent seed cluster that provides file segment download services and is also a client that downloads segments provided by other nodes.

[0143] It should be understood that selecting a peer node from the bitstream seed cluster and downloading the first data block through the peer node may be to match the data to be downloaded with the download data of the node in the bitstream seed cluster; selecting a peer node from the bitstream seed cluster based on the matching result, and downloading the first data block through the peer node.

[0144] In a specific implementation, in a BitTorrent seed cluster, multiple peer nodes can be searched and connected to, and these peer nodes have part or all of the data of the file that the user wishes to download. Then, one or more of the peer nodes can be selected to download the first data block.

[0145] It should be noted that a content delivery network node may refer to a single node in a CDN node cluster, which is responsible for caching and distributing specific content to improve the download or access speed of users.

[0146] In a specific implementation, the CDN node cluster may be composed of multiple geographically dispersed nodes, each of which caches a copy or fragment of the file. One or more nodes may be selected from the CDN node cluster to download the second data block according to the user's geographical location and network conditions.
