Example one
Fig. 1 is a flowchart of a file transmission method provided in an embodiment of the present disclosure, where this embodiment is applicable to a user obtaining a transmission file in a session page of a client, and the method may be executed by a file transmission apparatus in an embodiment of the present disclosure, where the apparatus may be implemented by software and/or hardware and integrated in a server, and may typically be integrated in a service server of social software, where the method specifically includes the following steps:
s110, responding to an operation request for obtaining a target file link, obtaining first authentication information of the target file link and second authentication information of the operation request; wherein the first authentication information and the second authentication information both include context information; the scene information comprises a client identification and/or a session page identification.
When a user transmits a file through a session page of a client, a server locally stores an acquired file to be transmitted, sends the stored file to a file receiver in a URL (uniform Resource locator) link (namely a file link), and simultaneously adds first authentication information into the file link; in the embodiment of the present disclosure, the server may provide a file transfer function for one or more types of clients; a session page identifier in the first authentication information, that is, identifier information of a session page used when a user transmits a file; the server can set a unique session page identifier for each session page according to the participants of the session and the creation time of the session; and after acquiring the operation request of the target file link, the server acquires the first authentication information by analyzing the target file link.
The client identifier in the second authentication information is the identifier information of the application program which sends the current operation request, and the session page identifier in the second authentication information is the identifier information of the session page which sends the current operation request; and after the server acquires the operation request linked with the target file, acquiring the second authentication information by analyzing the operation request.
