There is now a website that uses Baidu siteapp automatic transcoding service. Now it has developed its own mobile terminal. However, before, Baidu used automatic jumps to access the mobile terminal.

The current problem is how to make the previous access link automatically jump to the new link.

The transcoding link of Baidu siteapp is:
http://m.xxx.com/?src=http://www.xxx.com/north-america/america/2010/05...

Replace this part http://m.xxx.com/?src=http://www.xxx.com/ with http://m.xxx.com/

In this way, when users search for the content of this site through m.baidu.com, they can jump directly from the old url to the new url.

Can the above replacement function be implemented through nginx rules? Please help me heroes. Many thanks.
