Specifically, the server may create a compressed stream, and write the obtained download stream into the compressed stream according to the virtual path, so that when the user downloads the compressed stream, the original folder structure of the target download content may be saved. And the downloading stream is written into the compression stream, so that a mode of compressing while downloading can be realized, and the transmission efficiency of the target downloading content is improved.
In step S150, the compressed stream is uploaded to the cloud storage server again, and a download address corresponding to the compressed stream and fed back by the cloud storage server is received, where the download address includes address information of a distributed network.
In this embodiment, when compression is started, the server may upload the compressed stream to the cloud storage server again, and after receiving the compressed stream, the cloud storage server may generate a download address corresponding to the compressed stream and feed back the download address to the server. It is worth noting that when the cloud storage server starts to receive the compressed stream, the download address can be fed back to the server for the user to download without waiting for the completion of uploading of the compressed stream, so that the compression while downloading the stream, the uploading of the cloud storage server while compressing the target download file, and the downloading of the cloud storage server while uploading the target download file can be realized, and the transmission efficiency of the target download content is improved.
The download address may include address information of a distribution network, which may be a content distribution network or other network having a plurality of network nodes, and the address information may be a domain name or an IP address of the distribution network, which is not limited in particular.
In step S160, the download address is fed back to the target terminal, so that the target terminal can send a content download request to the distributed network again through the download address.
In this embodiment, the server may feed back the download address fed back by the cloud storage server to the target terminal, and the target terminal may send a content download request to the distributed network again according to the download address to obtain the target download content from the distributed network.

At this time, the content download request may include a folder identifier of the target download folder and a file identifier of the target download file.
Therefore, for a target download folder, the server may obtain file information of all subfiles (including files in the subfolders) included in the target download folder according to the folder identifier, and for the target download file, the server may obtain file information corresponding to the target download file according to the file identifier.
Based on the foregoing embodiments, in one embodiment of the present application, the target download content includes a target download folder and a target download file;
after acquiring the content information corresponding to the target download content according to the content identifier of the target download content, the method further includes:
and according to the file information corresponding to all the subfiles in the target download folder and the file information of the target download file, carrying out duplicate removal processing on the subfiles and the target download file.
In this embodiment, when the user downloads the folder and the file at the same time, after obtaining the file information corresponding to all the subfiles in the target download folder and the file information corresponding to the target download file, the user may compare the file information corresponding to all the subfiles in the target download folder with the file information corresponding to all the subfiles in the target download folder one by one, so as to perform deduplication processing on repeated files, that is, perform no repeated downloading subsequently, thereby saving the computing resources occupied by the downloading.
In one embodiment of the present application, the content download request further includes a user identification; acquiring content information corresponding to the target download content according to the content identifier of the target download content, including:
