[0076] In order to make the purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0077] In the description of the present application, it should be understood that the terms "first", "second" and the like are used only for descriptive purposes and are not intended to indicate or imply relative importance. In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or optionally also includes other steps or units inherent to the process, method, product or device. The specific meaning of the above terms in the present application can be understood by the person skilled in the art according to the specific circumstances. In addition, in the description of the present application, "multiple" means two or more, unless otherwise specified. The association relationship of the associated objects is described, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0078] In related technologies, in order to improve the picture preview experience of users, the Internet cloud disk application selects to shorten the loading and rendering time of the picture to speed up the display speed of the picture. The technical principle is: using HTML5 technology to obtain the source address of the picture in the cloud, then obtaining the corresponding picture resource from the source address, to load and render the picture into the user's browser, and the browser will also cache the picture, when the user accesses the picture again, directly obtain the picture from the cache without downloading the picture again, to shorten the loading and rendering time of the picture to speed up the display speed of the picture. In the above method, the source address of the picture in the cloud may be exposed, and there is a risk of exposing the source address. Therefore, how to improve the security of the storage address of the picture in the cloud is a technical problem to be solved.

[0079] In order to solve the above technical problems, the present application will be described in detail below in combination with specific embodiments.

[0080] Please refer to Figure 1 , a scene schematic diagram of a picture preview method provided by an embodiment of the present application.

[0081] As Figure 1 shown, the picture preview scene includes a server and at least one client, and the server and the client are connected respectively. It can be understood that the number of clients is only exemplary, and the number of clients is not limited by the embodiments of the present application.

[0082] In the embodiments of the present application, the server refers to an electronic device for managing and storing user data in cloud storage, and the client refers to a user device. The user can use the client to interact with the server to realize the storage of user data in cloud storage. For example, taking a cloud disk application for cloud storage as an example, the server can refer to an electronic device for managing and storing user data in the cloud disk application, and the client can refer to a user device that can access the software or website or applet of the cloud disk application. For example, the client can include but is not limited to tablet, computer, mobile phone and the like.

[0083] For example, the server can be a separate server device, and can also be a server cluster composed of multiple nodes. When the server is a server cluster composed of multiple nodes, each node in the server can be a separate server device, for example: rack, blade, tower or cabinet type server device, or a hardware device with strong computing power such as workstation, mainframe computer, etc.; or a server cluster composed of multiple servers, each server in the service cluster can be composed in a symmetrical manner, that is, each server is functionally equivalent and positionally equivalent in the transaction link, and each server can independently provide services to the outside. Providing services to the outside can be understood as not needing the assistance of other servers.

[0084] In the picture preview method provided by the embodiments of the present application, the server can perform the following steps: receiving a picture preview request sent by the client in a cloud storage scenario, determining a picture virtual mapping address based on the picture preview request; sending the picture virtual mapping address to the client, so that the client determines a target picture based on the picture virtual mapping address and performs preview display based on the target picture.

[0085] The picture preview method provided by the embodiments of the present application receives the picture preview request sent by the client in the cloud storage scenario to determine the picture virtual mapping address, and then sends the picture virtual mapping address to the client, so that the client can determine the target picture based on the picture virtual mapping address and perform preview display based on the target picture. The above method responds to the picture preview request of the client by sending the picture mapping virtual address to the client, instead of sending the real storage address of the picture in the cloud to the client, thereby avoiding the leakage of the real storage address of the picture in the cloud, and improving the security of the storage address of the picture in the cloud.

[0086] It should be noted that any one client can establish a communication connection with the server through the network for interactive communication, and any one client can also establish a communication connection with at least one node in the server through the network for interactive communication. Among them, the network can be a wireless network or a wired network, the wireless network includes but is not limited to a cellular network, a wireless local area network, an infrared network or a Bluetooth network, and the wired network includes but is not limited to an Ethernet, a universal serial bus (USB) or a controller area network. In one or more embodiments of the specification, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML) and the like are used to represent the data (such as the target compressed package) exchanged through the network. In addition, all or some links can be encrypted using conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) and the like. In other embodiments, custom and / or dedicated data communication technologies can be used instead of or in addition to the above data communication technologies.

[0087] In one embodiment, as shown in Figure 2 a picture preview method is proposed, which can be implemented by a computer program and can run on a picture preview device based on the von Neumann architecture. The computer program can be integrated in an application or run as an independent tool application.

[0088] Specifically, the execution subject of the picture preview method is a server, and the picture preview method comprises:

[0089] S201, receiving a picture preview request sent by a client in a cloud storage scenario, and determining a picture virtual mapping address based on the picture preview request.

[0090] The cloud storage scenario refers to a scenario of storing and managing user data by using cloud computing technology and infrastructure provided storage services. In the cloud storage scenario, a communication connection between the client and the server corresponding to the cloud disk application is established by taking the cloud disk application as a carrier. The cloud disk application allows users to upload files, documents, pictures, videos and other data to the server through the Internet, so as to access, share or backup these data anytime and anywhere.

[0091] The picture preview request refers to a preview request triggered by a user inputting a picture preview operation on a client. The picture preview request can be a preview request for previewing one picture or a preview request for previewing multiple pictures.

[0092] The picture virtual mapping address refers to a virtual storage address having a mapping relationship with a picture converted based on a cloud picture. The cloud picture is a picture stored in a server through a cloud disk application. After receiving a cloud picture uploaded by a user, the server can generate a picture virtual mapping address corresponding to a picture converted based on each cloud picture, and save the mapping relationship between the picture converted based on the cloud picture and the picture virtual mapping address.

[0093] For example, in a cloud storage scenario, a user stores pictures, files, documents, videos, and other data in a cloud disk application through a client. These data are uploaded to a server for storage through the cloud disk application. When the user accesses software of the cloud disk application or a website or a mini-program of the cloud disk application through the client, the user inputs a picture preview operation in the cloud disk application to trigger a picture preview request. The server can receive the picture preview request sent by the client. The server can analyze the picture preview request to determine a cloud disk picture requested by the user for preview and determine a picture virtual mapping address corresponding to a picture converted based on the cloud disk picture. When storing the cloud disk picture uploaded by the user, the server generates the picture virtual mapping address for the picture converted based on the cloud disk picture and stores the picture virtual mapping address. Therefore, after receiving the picture preview request, the picture virtual mapping address corresponding to the picture converted based on the cloud disk picture can be easily obtained by determining the cloud disk picture requested for preview.

[0094] It can be understood that the user in the embodiments of the present application can be an individual user or an enterprise user.

[0095] S202, sending the picture virtual mapping address to the client, so that the client determines a target picture based on the picture virtual mapping address and performs preview display based on the target picture.

[0096] The target picture refers to a converted picture corresponding to a cloud picture requested by the user for preview. The target picture can be a converted picture corresponding to one cloud picture, or converted pictures corresponding to multiple cloud pictures.

[0097] In some embodiments, when the user requests to preview multiple cloud pictures, the server can respectively determine the converted pictures corresponding to the cloud pictures respectively, determine the picture virtual mapping addresses corresponding to the converted pictures respectively, the server can send the multiple picture virtual mapping addresses to the client, and the server can also identify the picture identifiers corresponding to the picture virtual mapping addresses (the picture identifiers of the cloud pictures), so that the client can determine that the picture virtual mapping address is the picture virtual mapping address corresponding to the cloud picture indicated by the picture identifier, the client can obtain the target picture (the converted picture corresponding to the cloud picture) according to the picture virtual mapping address, and then output the preview display of the target picture. When the user requests to preview a cloud picture, the server determines the converted picture corresponding to the cloud picture, determines the picture virtual mapping address corresponding to the converted picture, and can directly send the picture virtual mapping address to the client, the converted picture determined according to the picture virtual mapping address by the client is the target picture, and then the preview display of the target picture is outputted.

[0098] The picture preview method provided by the embodiments of the present application receives the picture preview request sent by the client in the cloud storage scenario to determine the picture virtual mapping address, and then sends the picture virtual mapping address to the client, so that the client can determine the target picture according to the picture virtual mapping address and perform preview display based on the target picture. The above method responds to the picture preview request of the client by sending the picture mapping virtual address to the client, instead of sending the real storage address of the picture in the cloud to the client, thereby avoiding the real storage address of the picture in the cloud from being leaked, and improving the security of the storage address of the picture in the cloud.

[0099] Further, please refer to Figure 3 , Figure 3 is a flow diagram of another embodiment of a picture preview method proposed by the present application.

[0100] Specifically, the execution subject of the picture preview method is a server, and the picture preview method comprises the following steps.

[0101] S301, obtaining an original picture uploaded by a client in a cloud storage scenario, and performing picture conversion processing on the original picture to obtain a converted picture.

[0102] The original picture refers to a picture selected by a user from a local client and uploaded to a cloud disk application for cloud storage.

[0103] The converted picture refers to a picture obtained by performing conversion processing such as compression, cropping, format conversion, etc. on the original picture. The storage capacity of the converted picture can be smaller than that of the original picture.

[0104] In some embodiments, in a cloud storage scenario, a user stores pictures, files, documents, videos, etc. data in a cloud disk application through a client, and the data is uploaded to a server for storage through the cloud disk application. When the user accesses the software of the cloud disk application or the website of the cloud disk application or the applet of the cloud disk application through the client, the user inputs an upload operation for an original picture in the cloud disk application, and the client uploads the original picture to the server in response to the upload operation, so that the server can obtain the original picture. The number of original pictures can be one or more.

[0105] When the server performs the operation of performing picture conversion processing on the original picture to obtain a converted picture, it can specifically include: A1, obtaining a picture preview configuration mode corresponding to the client; A2, performing picture conversion processing on the original picture based on the picture preview configuration mode to obtain a converted picture.

[0106] The picture preview configuration mode can include at least one of a high-definition preview mode, a thumbnail preview mode, and a grid preview mode. The high-definition preview mode can refer to displaying a picture in high definition. The thumbnail preview mode can refer to displaying a picture in a small size and low resolution. The grid preview mode refers to arranging and displaying multiple thumbnails or pictures in a grid or rectangular shape.

[0107] When step A1 is performed, after the server receives the original picture uploaded by the client, the server can send a preview mode obtaining instruction to the client. The client obtains one or more picture preview configuration modes configured in the client in response to the preview mode obtaining instruction, and sends the picture preview configuration mode to the server, so that the server can obtain the picture preview configuration mode corresponding to the client. Specifically, the one or more picture preview modes configured in the client can be one or more picture preview modes configured by the user in the cloud disk application. The cloud disk application can be configured with a preview mode setting interface, and the user can set the corresponding picture preview mode according to the demand in the preview mode setting interface.

[0108] In the step A2, the following operations can be included: determining a picture conversion policy for the client based on the picture preview configuration mode; and performing picture conversion processing on the original picture based on the picture conversion policy to obtain a converted picture. The picture conversion policy can include at least one of a compression policy, a cropping policy, and a format conversion policy. Specifically, different picture preview configuration modes correspond to different picture conversion policies. For example, the picture conversion policy corresponding to the high-definition preview mode can be a format conversion policy, and the picture conversion policy corresponding to the thumbnail preview mode can include a compression policy and a cropping policy. The conversion policy mapping relationship can be pre-set based on expert experience, and the conversion policy mapping relationship can include at least one reference picture conversion policy corresponding to a reference preview configuration mode for a reference picture preview configuration mode. Then, the target picture conversion policy corresponding to the picture preview configuration mode can be queried in the conversion policy mapping relationship, and the target picture conversion policy is the picture conversion policy for the client. Further, the original picture is processed according to the picture conversion policy to obtain the converted picture. For example, the picture conversion policy is a format conversion policy, the original picture is in png format, and the converted picture obtained by the picture conversion policy is in ipeg format.

[0109] The converted picture obtained by the picture conversion policy has a storage capacity smaller than that of the original picture. Therefore, the converted picture can not only meet the preview requirements of different preview modes, but also ensure that the picture occupies less storage capacity in the case of distortion.

[0110] S302, the converted picture is processed to obtain a reference picture virtual mapping address.

[0111] The reference picture virtual mapping address refers to a virtual storage address having a mapping relationship with the converted picture, and the converted picture can be obtained through the reference picture virtual mapping address.

[0112] Specifically, the step S302 can include: determining an actual cloud storage address of the converted picture; and performing virtual address mapping processing based on the actual cloud storage address to obtain the reference picture virtual mapping address. The actual cloud storage address refers to the actual storage address of the converted picture in the cloud. Specifically, after obtaining the converted picture, the converted picture is stored in the cloud, and the actual storage address of the converted picture in the cloud, i.e. the actual cloud storage address, can be determined. The actual storage address is processed by virtual address mapping to obtain the reference picture virtual mapping address, so that the converted picture stored in the actual storage address can be obtained through the reference picture virtual mapping address without exposing the actual storage address.

[0113] Optionally, a picture virtual address data table can be configured for each picture preview configuration mode corresponding to a client, and a reference picture virtual mapping address corresponding to the picture preview configuration mode is stored in the picture virtual address data table. The reference picture virtual mapping address corresponding to the picture preview configuration mode refers to a reference picture virtual mapping address corresponding to a converted picture obtained by performing picture conversion on an original picture by using a picture conversion strategy corresponding to the picture preview configuration mode.

[0114] Optionally, after step S302 is performed, the method further includes: configuring an address validity duration for the reference picture virtual mapping address; and when it is monitored that a current validity duration of the reference picture virtual mapping address is greater than the address validity duration, performing address updating processing on the reference picture virtual mapping address based on an actual cloud storage address to obtain an updated reference picture virtual mapping address corresponding to the actual cloud storage address. The current validity duration refers to a duration from a time when the picture virtual mapping address is generated to a current time.

[0115] Specifically, the address validity duration can be configured for each reference picture virtual mapping address, and the address validity duration can be used to evaluate whether the reference picture virtual mapping address is invalid. When it is monitored that the current validity duration of the reference picture virtual mapping address is greater than the address validity duration, it is indicated that the reference picture virtual mapping address is invalid, and the reference picture virtual mapping address needs to be updated to obtain an updated reference picture virtual mapping address. For example, the address validity duration can be set to 1 hour, 3 hours, 6 hours, 8 hours, etc. In this way, by automatically monitoring the invalid reference picture virtual mapping address and updating the invalid reference picture virtual mapping address, the picture virtual mapping address can be prevented from being leaked externally.

[0116] It can be understood that after the reference picture virtual mapping address is invalid, the reference picture virtual mapping address in the virtual address data table can also be updated to the updated reference picture virtual mapping address, so as to ensure that the virtual address data table is updated along with the updating of the reference picture virtual mapping address.

[0117] S303, receiving a picture preview request sent by the client in the cloud storage scenario.

[0118] For example, in the cloud storage scenario, the picture preview request can be a preview request triggered by a user inputting a high-definition preview operation on the client, the picture preview request can also be a preview request triggered by a user inputting a thumbnail preview operation on the client, and the picture preview request can also be a preview request triggered by a user inputting a grid preview operation on the client. The client sends the picture preview request to the server in response to any one of the above picture preview requests, so that the server can receive the picture preview request.

[0119] S304, performing preview type analysis based on the picture preview request to obtain a target preview type.

[0120] The target preview type can include, but is not limited to, a high-definition preview type, a thumbnail preview type, a grid preview type, and the like.

[0121] In some embodiments, when the picture preview request is a preview request triggered based on a high-definition preview operation, the server can analyze the target preview type of the picture preview request as a high-definition preview type. When the picture preview request is a preview request triggered based on a thumbnail preview operation, the server can analyze the target preview type of the picture preview request as a thumbnail type. When the picture preview request is a preview request triggered based on a grid preview operation, the server can analyze the target preview type of the picture preview request as a grid preview type.

[0122] S305, determining a picture virtual mapping address corresponding to the picture preview request based on the target preview type.

[0123] In some embodiments, performing step S305 can include: obtaining a picture virtual address data table based on the target preview type; determining a picture preview range indicated by the picture preview request, and querying a picture virtual mapping address corresponding to the picture preview range based on the picture virtual address data table.

[0124] Specifically, as known from the above step S302, a picture virtual address data table is configured for each client corresponding to a picture preview configuration mode. The target preview type corresponding target picture preview configuration mode can be determined, and then the picture virtual address data table corresponding to the target picture preview configuration mode is obtained. When the target preview type is a high-definition preview type, the target picture preview configuration mode can be determined as a high-definition preview mode. When the target preview type is a thumbnail type, the target picture preview configuration mode can be determined as a thumbnail preview mode. When the target preview type is a grid preview type, the target picture preview configuration mode can be determined as a grid preview mode.

[0125] The picture preview request can carry a folder identifier of a picture folder requested by the user for preview, or carry a picture identifier of a certain picture or a picture requested by the user for preview. The server can perform identifier analysis on the picture preview request to obtain the folder identifier or the picture identifier, so as to determine a picture preview range indicated by the picture preview request according to the folder identifier or the picture identifier. The picture preview range includes one or more pictures requested by the user for preview. A converted picture corresponding to each picture in the picture preview range is determined, and a picture virtual mapping address corresponding to the converted picture is queried in the picture virtual address data table.

[0126] S306, send the picture virtual mapping address to the client, so that the client determines the target picture based on the picture virtual mapping address and performs preview display based on the target picture.

[0127] In some embodiments, when the picture preview range indicated by the picture preview request includes multiple pictures, the server can send the picture virtual mapping addresses corresponding to the multiple pictures to the client, and the server can also identify the picture identifiers corresponding to the picture virtual mapping addresses, so that the client can determine that the picture virtual mapping addresses correspond to the target pictures corresponding to the picture identifiers, the target pictures are the converted pictures corresponding to the pictures, and then the target pictures are used for preview display. When the picture preview range indicated by the picture preview request includes one picture, the server can directly send the picture virtual mapping address corresponding to the picture to the client, and the converted picture determined by the client based on the picture virtual mapping address is the target picture, and then the target picture is used for preview display.

[0128] The picture preview method provided by the embodiments of the present application first obtains an original picture uploaded by a client in a cloud storage scenario, performs picture conversion processing on the original picture to obtain a converted picture, performs virtual address mapping processing on the converted picture to obtain a reference picture virtual mapping address, converts the original picture uploaded by the user to the cloud to obtain a converted picture with a smaller storage capacity than the original picture, hides the actual cloud storage address of the converted picture, and determines the reference picture virtual mapping address corresponding to the converted picture. Then, when receiving a picture preview request sent by the client, the target preview type is obtained by performing preview type analysis processing based on the picture preview request, and the picture virtual mapping address corresponding to the picture preview request is determined based on the target preview type, so that the picture virtual mapping address corresponding to the picture preview request can be obtained from the previously stored reference picture virtual mapping address when the user requests to preview the picture. Finally, the picture virtual mapping address is sent to the client, so that the client determines the target picture based on the picture virtual mapping address and performs preview display based on the target picture. For the picture preview request sent by the client, the server does not send the actual cloud storage address corresponding to the original picture to the client, but sends the picture virtual mapping address corresponding to the original picture to the client, and the client can also obtain the corresponding picture resource based on the picture virtual mapping address and perform preview display based on the picture resource. Therefore, the embodiments of the present application provide preview display of the picture for the user without exposing the actual cloud storage address of the picture, ensure the security of the actual cloud storage address of the picture, and the picture resource obtained by the client based on the picture virtual mapping address can not only meet the preview requirements of different preview modes, but also can improve the picture preview display speed by loading a picture resource with smaller capacity without distortion.

[0129] Next, see Figure 4 , a flowchart of an embodiment of a picture preview method provided for an embodiment of the present application.

[0130] Specifically, the execution subject of the picture preview method is a client, and the picture preview method comprises:

[0131] S401, obtaining a picture preview request in a cloud storage scenario, sending the picture preview request to a server to enable the server to determine a picture virtual mapping address based on the picture preview request.

[0132] Illustratively, in the cloud storage scenario, a user stores pictures, files, documents, videos and other data in a cloud disk application through a client, and these data are uploaded to a server for storage through the cloud disk application. When the user accesses the software of the cloud disk application or the website of the cloud disk application or the applet of the cloud disk application through the client, the user inputs a picture preview operation in the cloud disk application to trigger the client to generate a picture preview request. The client sends the picture preview request to the server corresponding to the cloud disk application, so that the server determines a picture virtual mapping address based on the picture preview request.

[0133] It can be understood that the user can be a personal user or an enterprise user.

[0134] The picture preview request can be a preview request for previewing one picture, or can be a preview request for previewing multiple pictures.

[0135] S402, receiving the picture virtual mapping address sent by the server, determining a target picture based on the picture virtual mapping address, and performing preview display based on the target picture.

[0136] In some embodiments, after the client sends the picture preview request to the server, the client can receive the picture virtual mapping address returned by the server based on the picture preview request. The client can obtain a picture resource according to the picture virtual mapping address, load and render a target picture according to the picture resource, and output the target picture to perform preview display in response to the picture preview request.

[0137] The target picture can be a converted picture corresponding to the picture requested by the user for preview in the cloud.

[0138] The picture preview method provided by the embodiments of the present application sends a picture preview request obtained by a client in a cloud storage scenario to a server, so that the server can determine a picture virtual mapping address according to the picture preview request, and the picture virtual mapping address sent by the server is received, so that a target picture can be determined according to the picture virtual mapping address, and preview display is performed based on the target picture. In the method, the server does not send the real storage address of the picture in the cloud to the client, but sends the picture mapping virtual address to the client, so that the real storage address of the picture in the cloud is avoided to be leaked, and the security of the storage address of the picture in the cloud is improved.

[0139] Further, please refer to Figure 5 , a flowchart of another embodiment of a picture preview method provided by the embodiments of the present application.

[0140] Specifically, the execution subject of the picture preview method is a client, and the picture preview method comprises the following steps.

[0141] S501, an original picture selected from the local for a cloud storage scenario is obtained, and the original picture is uploaded to a server, so that the server determines a reference picture virtual mapping address based on the original picture.

[0142] In the cloud storage scenario, a user stores pictures, files, documents, videos and other data in a cloud disk application through a client, and the data is uploaded to a server for storage through the cloud disk application.

[0143] Illustratively, a user can access the software of the cloud disk application or the website of the cloud disk application, or the applet of the cloud disk application through a client, and the user can select an original picture stored locally in the cloud disk application, can input an upload operation for the original picture, and the client uploads the original picture to the server in response to the upload operation. In this way, the server can store the original picture, and the server can also determine a reference picture virtual mapping address according to the original picture. Specifically, the server can perform picture conversion processing on the original picture to obtain a converted picture, and perform virtual address mapping processing on the converted picture to obtain the reference picture virtual mapping address. For the implementation of the server to obtain the reference picture virtual mapping address, please refer to the description of S301 and S302 in the embodiment shown in Figure 3

[0144] S502, a picture preview request in the cloud storage scenario is obtained, and the picture preview request is sent to the server, so that the server determines a picture virtual mapping address based on the picture preview request.

[0145] ​For example, when a user accesses the software of the cloud disk application or the website of the cloud disk application or the applet of the cloud disk application through a client, the user inputs a picture preview operation in the cloud disk application, triggering the client to generate a picture preview request. The client sends the picture preview request to the server corresponding to the cloud disk application, so that the server determines a picture virtual mapping address based on the picture preview request.

[0146] It can be understood that the picture preview request can be a preview request triggered by the client based on a high-definition preview operation input by the user in the cloud disk application, the picture preview request can also be a preview request triggered by the client based on a thumbnail preview operation input by the user in the cloud disk application, and the picture preview request can also be a preview request triggered by the client based on a grid preview operation input by the user in the cloud disk application.

[0147] S503, receiving the picture virtual mapping address sent by the server.

[0148] In some embodiments, the number of picture virtual mapping addresses sent by the server can be one or more. When the picture preview request sent by the client is a preview request for multiple pictures, the number of picture virtual mapping addresses received by the client is also multiple, one picture virtual mapping address corresponds to one picture, and in this case, each picture virtual mapping address can correspond to a picture identifier, which can be used by the client to identify that the picture virtual mapping address corresponds to the picture indicated by the picture identifier.

[0149] When the picture preview request sent by the client is a preview request for one picture, the picture virtual mapping address received by the client is the picture virtual mapping address corresponding to the picture.

[0150] S504, determining a target picture based on the picture virtual mapping address, and performing preview display based on the target picture.

[0151] In some embodiments, after the client sends the picture preview request to the server, the client can receive the picture virtual mapping address returned by the server based on the picture preview request. The client can obtain picture resources according to the picture virtual mapping address, load and render a target picture according to the picture resources, and output the target picture to perform preview display in response to the picture preview request.

[0152] It can be understood that the storage capacity of the picture resources obtained by the client according to the picture virtual mapping address is smaller than the storage capacity of the original picture, because the picture resources obtained through the picture virtual mapping address are picture resources of a converted picture obtained by the server by performing picture conversion processing on the original picture. The server performs conversion processing on the original picture by using strategies such as format conversion, compression, and cropping, so that the server can reduce the storage capacity of the picture while ensuring no loss of quality.

[0153] When the picture preview request is a preview request triggered by the client generated by the user inputting a high-definition preview operation in the cloud disk application, the client performs preview display based on the target picture, that is, the client displays the target picture according to the picture resource with high definition to realize high-definition preview display.

[0154] When the picture preview request is a preview request triggered by the client generated by the user inputting a thumbnail preview operation in the cloud disk application, the client performs preview display based on the target picture, that is, the client displays the thumbnail corresponding to the cloud picture according to the picture resource to realize thumbnail preview display.

[0155] When the picture preview request is a preview request triggered by the client generated by the user inputting a mosaic preview operation in the cloud disk application, the client performs preview display based on the target picture, that is, the client displays the mosaic display picture corresponding to the cloud picture according to the picture resource to realize mosaic preview display.

[0156] The picture preview display method provided by the embodiment of the application can meet the preview requirements of different preview modes through the picture resources obtained by the client through the picture virtual mapping address sent by the server, and the storage capacity of the picture resources is smaller than that of the original picture, so that the client improves the picture preview display speed by loading the picture resources with smaller capacity without distortion.

[0157] The picture preview display method provided by the embodiment of the application can meet the preview requirements of different preview modes through the picture resources obtained by the client through the picture virtual mapping address sent by the server, and the storage capacity of the picture resources is smaller than that of the original picture, so that the client improves the picture preview display speed by loading the picture resources with smaller capacity without distortion.
