Customized development of WeChat public address

1, configure public number - Development - Web Services - webpage authorization - modify Authorized access to basic user information Authorized domain name (Note: public number automatic recovery development, need to open server configuration, separate access to user information is not required. jssdk is a white list authorization management. )

2. Menu access: when accessing http:// XXX / - user/info, the user is authorized. After authorization, the user will jump to http://XXX/home?code=xxx (configuration). At this time, call http:// XXX / - user/info again to get the user information and put it into the session (for later interface access)

Code reference:



AppID = ''
AppSecret = ''
Token = ''
