In some embodiments, the authorization server generates first device information for the first device from the connection establishment request, the first device information including a first device identification (e.g., a first device code).

Step S04, the first device presents the first device code to a user.

Step S05, the user opens a target website in the second device according to the first device code displayed by the first device, inputs user information, selects a target file, and inputs information for the target file.

Step S06, the second device sends the input information to an online document server and requests authorization.

Step S07, the online document server authorizes the authorization server, and sends the file token, the file information, and the first device code of the target file.

And if the input information of the second equipment is successfully matched with the first equipment code. The authorization server judges that the authorization is successful and proceeds to step S08.

Step S08, the authorization server searches the connection information of the first device according to the first device code, and transmits the document information and the file token to the first device.

In step S09, the first device requests the online document server to open a target file, and transmits first device information (including a device code and a device token), file token information, and file information.

Step S10, the online document server checks the correspondence between the file token, the file information, and the first device information with the authorization service.

In some embodiments, the online document server may perform verification according to the first device token, the file information, and the file token, and may send the file content of the target file to the first device if the online document server determines that the first device token, the file information, and the file token have a correspondence relationship.

According to the method, the file token and the file information of the target file are transmitted between the server and the first device through the file token, so that the target file is prevented from being directly transmitted between the devices, and the safety of information transmission is improved. In addition, after the server information is successfully verified, the target file is sent to the first device to be displayed, so that an information verification link is added, and the information safety is improved again.

Step S11, if the verification is successful, the online document server sends the target file content to the first device.

In step S12, the first device presents the target file to the user.
