Don't sink!

Third-party platform ....

Public numbers (public platforms) and open platforms are different. Public number (public platform) access to the scope only includes two kinds: snsapi_base and Snsapi_userinfo, the former is silent access, the user is not aware, the latter requires user confirmation of consent.

But open platform (https://open.weixin.qq.com/) can get snsapi_login this scope. The pit daddy is, public platform certification and open platform certification is independent, if you want to get snsapi_login, also need to re-register open platform, pay 300 dollars certification.

If you just want to implement scan QR code login, in fact, Snsapi_base is enough, because it can get to the user's OpenID, you can later be used to compare with their own database.

If you do not understand, you can refer to this, I have made the API, more simple to use:
