Abstract

A file transmission method and system relate to the technical field of communications networks, which can perform file resource sharing, so as to accelerate file transmission and publication, reduce time consumption, and save storage space. A browser upload plug-in at a client scans a to-be-uploaded file, acquires a unique identifier of the to-be-uploaded file, and sends the unique identifier to an instant-publishing management server. The instant-publishing management server determines, according to the unique identifier, whether the to-be-uploaded file corresponding to the unique identifier exists in a cloud storage server. The instant-publishing management server generates a download link of the to-be-uploaded file when the to-be-uploaded file corresponding to the unique identifier exists in the cloud storage server, and sends the download link of the to-be-uploaded file to the browser upload plug-in, so that a webmaster publishes the download link of the to-be-uploaded file on a website to provide a download service.

the instant-publishing management server determining, according to the unique identifier, whether the to-be-uploaded file corresponding to the unique identifier exists in a cloud storage server; and

when the to-be-uploaded file corresponding to the unique identifier exists in the cloud storage server, the instant-publishing management server generating a download link of the to-be-uploaded file and sending the download link of the to-be-uploaded file to the browser upload plug-in, wherein a webmaster is configured to publish the download link of the to-be-uploaded file on a website to provide a download service.

2. The method according to claim 1, wherein the step of the instant-publishing management server generating a download link of the to-be-uploaded file comprises:

generating a download address of the to-be-uploaded file according to related information of the to-be-uploaded file, wherein the related information of the to-be-uploaded file comprises the unique identifier, a publication timestamp of the to-be-uploaded file, a user identifier of the webmaster that uploads the to-be-uploaded file, and verification information of the to-be-uploaded file.

3. The method according to claim 1, further comprising:

when the to-be-uploaded file corresponding to the unique identifier does not exist in the cloud storage server;

the instant-publishing management server acquiring an upload interface address of an upload interface server and sending the upload interface address to the browser upload plug-in;

the browser upload plug-in uploading the to-be-uploaded file to the upload interface server according to the upload interface address; and

the upload interface server storing the to-be-uploaded file in the cloud storage server so as to provide a download service for a download client.

4. The method according to claim 3, wherein data stored in the cloud storage server further comprises data downloaded by an offline download server.

5. The method according to claim 4, wherein the offline download server is further configured to:

receive a file identifier of a to-be-offline-downloaded file sent by an offline download task scheduling server;

query, according to the file identifier, a database for a download link of the to-be-offline-downloaded file corresponding to the file identifier, and download the to-be-offline-downloaded file according to the download link; and

store data of the to-be-offline-downloaded file in the cloud storage server when the to-be-offline-downloaded file is downloaded completely, and store a unique identifier of the to-be-offline-downloaded file in the database.

6. The method according to claim 5, wherein the offline download server is further configured to report a download process of the to-be-downloaded file to an offline task management server, so that the download client views the offline download process.

7. The method according to claim 6, wherein the offline task management server is configured to:

receive a task of a to-be-offline-downloaded file sent by the download client, and query whether a unique identifier of the to-be-offline-downloaded file exists in the database;

send, to the download client, a message indicating that the to-be-offline-downloaded file has been downloaded completely when the unique identifier of the to-be-offline-downloaded file exists in the database, wherein the message comprises an address used for retrieving data of the to-be-offline-downloaded file; and

generate a file identifier for the task of the to-be-offline-downloaded file when the unique identifier of the to-be-offline-downloaded file does not exist in the database, send the file identifier and a download link of the to-be-offline-downloaded file to the database, and send an offline download task request message to the offline task scheduling server, wherein the offline download task request message comprises the task of the to-be-offline-downloaded file and the file identifier.

8. A file transmission system, comprising:

a client including a browser upload plug-in; and

an instant-publishing management server that is communicatively coupled to the client,

wherein;

the browser upload plug-in is configured to scan a to-be-uploaded file, acquire a unique identifier of the to-be-uploaded file, and send the unique identifier to the instant-publishing management server; and

the instant-publishing management server is configured to determine, according to the unique identifier, whether the to-be-uploaded file corresponding to the unique identifier exists in a cloud storage server; and

generate a download link of the to-be-uploaded file when the to-be-uploaded file corresponding to the unique identifier exists in the cloud storage server, and send the download link of the to-be-uploaded file to the browser upload plug-in, so that a webmaster publishes the download link of the to-be-uploaded file on a website to provide a download service.

9. The system according to claim 8, wherein the instant-publishing management server is configured to generate a download address of the to-be-uploaded file according to related information of the to-be-uploaded file, wherein the related information of the to-be-uploaded file comprises the unique identifier, a publication timestamp of the to-be-uploaded file, a user identifier of the webmaster that uploads the to-be-uploaded file, and verification information of the to-be-uploaded file.

10. The system according to claim 8, wherein:

the instant-publishing management server is further configured to acquire an upload interface address of an upload interface server when the to-be-uploaded file corresponding to the unique identifier does not exist in the cloud storage server, and send the upload interface address to the browser upload plug-in;

the browser upload plug-in is further configured to upload the to-be-uploaded file to the upload interface server according to the upload interface address; and

the upload interface server is configured to store the to-be-uploaded file in the cloud storage server, so as to provide a download service for a download client.

11. The system according to claim 10, wherein data stored in the cloud storage server further comprises data downloaded by an offline download server.

12. The system according to claim 11, wherein the offline download server is further configured to:

receive a file identifier of a to-be-offline-downloaded file sent by an offline download task scheduling server;

query, according to the file identifier of the to-be-offline-downloaded file, a database for a download link of the to-be-offline-downloaded file corresponding to the number of the to-be-offline-downloaded file, and download the to-be-offline-downloaded file according to the download link; and
