After exchange files platform obtains file extraction code and log-on message, exchange files platform is by file extraction code and steps on
Record information is sent to receiving end.After receiving end receives the file extraction code and log-on message of exchange files platform transmission, connect
Receiving end, which detects whether to detect, receives the logging request that end subscriber triggers log file switching plane according to log-on message.Work as reception
After end detects logging request, prompt information is exported according to logging request log file switching plane, and in its display interface,
To prompt user-in file extraction code according to the prompt information, file extraction code is sent to exchange files platform.
Such as after file extraction code and log-on message are sent to the mailbox for receiving end subscriber by exchange files platform, receiving end
User can log in its mailbox and obtain file extraction code and log-on message, voluntarily input network address and log on exchange files platform or logical
After crossing URL link to exchange files platform, then pass through the logon account and login password log file switching plane of log-on message,
Trigger logging request.It should be noted that carrying logon account and login password in logging request.
Step S40 extracts code check according to the file that the receiving end is sent after determining that the receiving end logins successfully
The receiving end is with the presence or absence of the download permission for downloading the file to be sent.
After exchange files platform receives the file extraction code and logging request of receiving end transmission, exchange files platform root
Whether successfully logged according to logging request verification receiving end.If the logon account and login password in logging request are all correct, file
Switching plane then determines that receiving end logins successfully.It is understood that when the logon account in logging request is put down with exchange files
The logon account that platform is created is consistent, and the login password that the login password in logging request and exchange files platform generate at random
When consistent, exchange files platform determines that logon account in logging request and login password are correct, determines that receiving end logins successfully,
No person, it is determined that receiving end login failure.After exchange files platform determines that receiving end logins successfully, exchange files platform according to
The file that receiving end is sent extracts code check receiving end with the presence or absence of the download permission for downloading file to be sent.
Further, if exchange files platform determines receiving end login failure, it is determined that receiving end is pending there is no downloading
The download permission of file is sent, rejection end obtains file to be sent, i.e., do not allow receiving end to download in exchange files platform
File to be sent.
Step S50 sends out the file to be sent according to downloading request if there are the download permissions for the receiving end
The receiving end is given, so that the file to be sent is downloaded in the receiving end.
If exchange files platform determines receiving end there are download permission, exchange files platform can be sent out receiving receiving end
File to be sent is sent to receiving end when the file download request sent, so that receiving end gets file to be sent, i.e., so that
Successfully download file to be sent in receiving end.After file to be sent is successfully downloaded in receiving end, receiving end can be used this to be sent
File.
