WeChat applet getPhoneNumber interface code=40013

Record a problem encountered in the development process, obtain the user's mobile phone number through the getPhoneNum interface, and WeChat returns

code=40013, msg=invalid appid

Failed to get WeChat phone number, code=40013, msg=invalid appid

Invalid appid, then check the official interface documentation and find that we are not allowed to pass appid

phonenumber.getPhoneNumber | WeChat Open Documentation

But let's pass an interface call credential access_token, we need to pass the appId when we get this credential

auth.getAccessToken | WeChat Open Documentation

There is also a parameter code. This code is obtained by the applet through the wx.login interface. The WeChat applet has its own appid. If the appid we use to obtain the calling certificate is different from the appid used by the applet, it is better to obtain the mobile phone.will return 40013, invalid appId, the two appIds are the same.
