Wechat says in the open platform:
for security reasons, the login of Wechat of the website application needs to be realized by Wechat scanning the QR code. https://open.weixin.qq.com/cg.
it is convenient to log in with Wechat on pc and scan the QR code. It is too troublesome on the mobile end, for example, users enter the H5 page of the website through Baidu search on the mobile terminal, scan the QR code to log in to Wechat, save the QR code or screenshot first, then open Wechat, and then select the QR code from the album, and then identify it.
question:
can you directly call Wechat to scan when the mobile H5 page presses the QR code?
