Can the official WeChat account applet identify your WeChat mobile phone number?

WeChat official account applet cannot recognize WeChat mobile phone number.

On the official account page of WeChat, in one operation, the user must bind the mobile phone number to obtain SMS verification code verification.

To obtain the mobile phone number bound by WeChat users, you need to call the wx.login interface first. Because the user needs to actively trigger the interface to get the mobile phone number, this function is not called by API, but triggered by clicking the button component. You need to set the value of the button component open-type to getPhoneNumber. After the user clicks "Agree", you can get the encrypted data returned by the WeChat server through the bindgetphonenumber event callback, and then decrypt it on the third-party server in combination with session_key and app_id to get the mobile phone number.
