[0004] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0005] According to one aspect of the embodiments of this application, a file download method based on cloud storage service is provided, the method comprising:

[0006] Receive a content download request sent by a target terminal, wherein the content download request includes a content identifier of the target download content;

[0007] Based on the content identifier of the target download content, obtain the content information corresponding to the target download content, the content information including the virtual path and storage address corresponding to the target download content;

[0008] Based on the storage address, obtain the download stream corresponding to the target download content from the cloud storage server;

[0009] Instantiate a compressed stream, and write the download stream into the compressed stream according to the virtual path;

[0010] The compressed stream is re-uploaded to the cloud storage server, and the download address corresponding to the compressed stream is received from the cloud storage server. The download address contains address information of the distributed network.

[0011] The download address is fed back to the target terminal so that the target terminal can resend the content download request to the distributed network using the download address.

[0012] According to one aspect of the embodiments of this application, a file download device based on cloud storage service is provided, the device comprising:

[0013] The receiving module is used to receive a content download request sent by the target terminal, wherein the content download request includes a content identifier of the target download content;

[0014] The first acquisition module is used to acquire content information corresponding to the target download content based on the content identifier of the target download content. The content information includes the virtual path and storage address corresponding to the target download content.

[0015] The second acquisition module is used to acquire the download stream corresponding to the target download content from the cloud storage server according to the storage address;

[0016] A compression module is used to instantiate a compressed stream and write the download stream into the compressed stream according to the virtual path;

[0017] The return module is used to re-upload the compressed stream to the cloud storage server and receive the download address corresponding to the compressed stream from the cloud storage server, wherein the download address contains address information of the distributed network.

[0018] The processing module is used to send the download address back to the target terminal, so that the target terminal can resend the content download request to the distributed network using the download address.

[0019] According to one aspect of the embodiments of this application, a computer-readable medium is provided having a computer program stored thereon, which, when executed by a processor, implements the file download method based on cloud storage services as described in the above embodiments.

[0020] According to one aspect of the embodiments of this application, an electronic device is provided, including: one or more processors; and a storage device for storing one or more programs, wherein when the one or more programs are executed by the one or more processors, the one or more processors implement the file download method based on cloud storage services as described in the above embodiments.

[0021] According to one aspect of the embodiments of this application, a computer program product or computer program is provided, which includes computer instructions stored in a computer-readable storage medium. A processor of a computer device reads the computer instructions from the computer-readable storage medium and executes the computer instructions, causing the computer device to perform the file download method based on cloud storage services provided in the above embodiments.

[0022] In some embodiments of this application, the technical solutions involve receiving a content download request sent by a target terminal. This content download request includes a content identifier of the target download content. Based on the content identifier, the corresponding content information is obtained. This content information includes the virtual path and storage address of the target download content. Based on the storage address, the download stream corresponding to the target download content is obtained from the cloud storage server. A compressed stream is then instantiated, and the download stream is written into the compressed stream according to the virtual path. The compressed stream is then re-uploaded to the cloud storage server. The download address corresponding to the compressed stream, which contains the address information of the distributed network, is received from the cloud storage server. This download address is then fed back to the target terminal so that the target terminal can resend the content download request to the distributed network using the download address.

[0023] Therefore, by using both download and compression streams, the download and compression of the target content can be performed simultaneously. The compressed stream is then re-uploaded to the cloud storage server, generating a corresponding download address containing distributed network address information. This allows the target terminal to initiate a content download request to the distributed network to download the corresponding content from the nearest distributed network node, thereby improving file download efficiency. Furthermore, downloading through distributed network nodes, even when returning to the origin server, utilizes its internal network, saving bandwidth costs and eliminating restrictions on the size of the downloaded file.

That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0032] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0033] Figure 1 The diagram illustrates a flowchart of a file download method based on cloud storage services according to an embodiment of this application. This method can be applied to a server, which can be a physical server or a cloud server providing various cloud services. It should be noted that the server can be a single server or a server cluster composed of multiple servers; no particular limitation is made in this regard.

[0034] Reference Figure 1As shown, this file download method based on cloud storage service includes at least steps S110 to S160, which are described in detail below:

[0035] In step S110, a content download request sent by the target terminal is received, wherein the content download request includes the content identifier of the target download content.

[0036] Specifically, users can browse and manage the file storage space on a web page. When a download is needed, the user can select the content to be downloaded to generate a download request and send it to the server. This download request can include the content identifier of the target content, such as the filename or number. Upon receiving the download request, the server can parse it to obtain the content identifier of the target content.

[0037] In step S120, based on the content identifier of the target download content, the content information corresponding to the target download content is obtained, and the content information includes the virtual path and storage address corresponding to the target download content.

[0038] Specifically, the server can query the correspondence between the content identifier and the content information based on the content identifier of the target download content, thereby determining the content information corresponding to the target download content. This content information may include, but is not limited to, the virtual path and storage address corresponding to the target download content. The virtual path may be used to describe the storage directory of the target download content, and the storage address may be a network link, which allows access to the corresponding target download content.

[0039] In step S130, the download stream corresponding to the target download content is obtained from the cloud storage server according to the storage address.

[0040] In step S140, a compressed stream is instantiated, and the download stream is written into the compressed stream according to the virtual path.

[0041] Specifically, the server can create a compressed stream and write the acquired download stream into it based on the virtual path. Thus, when a user downloads the compressed stream, the original folder structure of the target download content can be preserved. Furthermore, by writing the download stream into the compressed stream, compression can be performed while downloading, improving the transmission efficiency of the target download content.

[0042] In step S150, the compressed stream is re-uploaded to the cloud storage server, and the download address corresponding to the compressed stream is received from the cloud storage server. The download address contains address information of the distributed network.

[0043] In this embodiment, when compression begins, the server can re-upload the compressed stream to the cloud storage server. After receiving the compressed stream, the cloud storage server can generate a download address corresponding to the compressed stream and send the download address back to the server. It is worth noting that when the cloud storage server starts receiving the compressed stream, it does not need to wait for the compressed stream to finish uploading; it can immediately send the download address back to the server for the user to download. This allows for simultaneous acquisition and compression of the download stream, simultaneous compression of the target download file and uploading to the cloud storage server, and simultaneous uploading to the cloud storage server and downloading by the user, improving the transmission efficiency of the target download content.

[0044] The download address may contain address information of a distributed network, which may be a content delivery network or other network with multiple network nodes. The address information may be the domain name or IP address of the distributed network, without any special restrictions.

[0045] In step S160, the download address is fed back to the target terminal so that the target terminal can resend the content download request to the distributed network through the download address.

[0046] In this embodiment, the server can send the download address returned by the cloud storage server back to the target terminal. Based on the download address, the target terminal can resend the content download request to the distributed network to obtain the target download content from the distributed network. Thus, downloading through the distributed network allows for the selection of the nearest distributed network node for downloading, improving transmission efficiency. Furthermore, there is no need to limit the size of the downloaded file, enhancing the user experience.

[0047] In one embodiment of this application, the target download content includes a target download folder and / or a target download file;

[0048] Then, based on the content identifier of the target download content, the content information corresponding to the target download content is obtained, including:

[0049] Based on the folder identifier of the target download folder, obtain the file information corresponding to all sub-files under the target download folder;

[0050] and / or

[0051] Based on the file identifier of the target download file, obtain the file information corresponding to the target download file.

[0052] In this embodiment, the target download content may include a target download folder and / or a target download file; that is, the user can download either a folder or a single file. In this case, the content download request may include the folder identifier of the target download folder and the file identifier of the target download file.

[0053] Therefore, for a target download folder, the server can obtain the file information of all sub-files (including files in subfolders) contained in the target download folder based on the folder identifier, and for a target download file, the server can obtain the file information corresponding to the target download file based on the file identifier.

[0054] Based on the foregoing embodiments, in one embodiment of this application, the target download content includes a target download folder and a target download file;

[0055] After obtaining the content information corresponding to the target download content based on the content identifier of the target download content, the method further includes:

[0056] Based on the file information corresponding to all sub-files in the target download folder and the file information of the target download file, deduplication is performed on the sub-files and the target download file.

[0057] In this embodiment, when a user downloads both a folder and a file simultaneously, after obtaining the file information corresponding to all sub-files under the target download folder and the file information corresponding to the target download file, the user can compare the two. That is, the file information of the target download file is compared one by one with the file information corresponding to all sub-files under the target download folder, thereby deduplicating duplicate files and preventing them from being downloaded repeatedly. This saves the computing resources used for downloading.

[0058] In one embodiment of this application, the content download request further includes a user identifier; then, based on the content identifier of the target download content, obtaining the content information corresponding to the target download content includes:

[0059] Download permission verification is performed based on the user identifier and the content identifier of the target download content;

[0060] If the download permission verification is passed, the content information corresponding to the target download content is obtained based on the content identifier of the target download content.

[0061] In this embodiment, the content download request may also include a user identifier, such as a user account. The server then performs download permission verification based on the user identifier and the content identifier of the target download content. In one example, the server can query the permission information corresponding to the target download content based on its content identifier, such as the uploader's information and the allowed download range. This allows the server to determine whether the user identifier falls within the allowed download range of the target download content. If it does, the download permission verification passes; otherwise, it fails. Only after passing the download permission verification does the server obtain the content information corresponding to the target download content, thus ensuring the security of the stored files.

[0062] In one example, a user can be restricted to downloading only files they have previously uploaded. In this case, the server can compare the user's identifier with the uploader information of the target download content. If they match, the download is allowed; if they do not match, the download is rejected.

[0063] Based on the technical solutions of the above embodiments, the following describes a specific application scenario of an embodiment of this application:

[0064] This application also provides a file download system based on cloud storage services, which includes compression services, digital asset services, asset mapping relationship storage services, acceleration services, and file cloud storage services.

[0065] The compression service provides an interface for interaction with the target terminal, allowing users to interact with the compression service through the target terminal. The digital asset service verifies permissions for files downloaded by the user. The asset mapping storage service stores and queries the correspondence between file identifiers and file information. The acceleration service, or content delivery network, provides download acceleration services. The file cloud storage service provides file storage functionality.

[0066] Based on the above system, in one embodiment of this application, the file download method based on cloud storage service includes the following steps:

[0067] Step S210: The user selects the files and folders to be downloaded in a package and clicks download;

[0068] In step S220, the compression service receives the user's download request and performs relevant download permission verification in the digital asset service based on the file identifier and folder identifier contained in the download request.

[0069] In step S230, after the download permission is verified, the asset mapping relationship storage service queries the file information of all sub-files under the folder based on the folder identifier, then queries the corresponding file information based on the file identifier, and performs deduplication based on the two.

[0070] In step S240, the compression service extracts the virtual path and storage address of the file from the file information, and obtains the download stream of the corresponding file from the file cloud storage service based on the storage address.

[0071] Step S250: The compression service instantiates a compression stream and writes the download stream of the corresponding file into the corresponding compression stream according to the corresponding virtual path.

[0072] In step S260, the compression service re-uploads the compressed stream to the file cloud storage service and receives the download address returned by the file cloud storage service, so as to send the download address to the target terminal.

[0073] In step S270, the target terminal sends a download request to the acceleration service based on the download address. The acceleration service retrieves the corresponding compressed package from the file cloud storage service and sends it to the target terminal.

[0074] Therefore, by using both download and compression streams, the download and compression of the target content can be performed simultaneously. The compressed stream is then re-uploaded to the cloud storage server, generating a corresponding download address containing distributed network address information. This allows the target terminal to initiate a content download request to the distributed network to download the corresponding content from the nearest distributed network node, thereby improving file download efficiency. Furthermore, downloading through distributed network nodes, even when returning to the origin server, utilizes its internal network, saving bandwidth costs and eliminating restrictions on the size of the downloaded file.
