Users can obtain login information by scanning the QR code provided by the webpage. /** * Public platform PHP-SDK * Wechatauth is an unofficial API login * Users can obtain login information by scanning the QR code provided by the webpage. * Mainly implements the following functions: * Get_login_code () obtains the logon authorization code. only the two-dimensional code can be obtained through the authorization code. * Get_code_image ($ code = '') converts the authorization code obtained above to the image QR code * Verify_code () indicates whether the logon is successful. if 200 is returned, the final authorization is successful. * After the get_login_cookie () authentication is successful, call this method to obtain basic user information. * SendNews ($ account, $ title, $ summary, $ content, $ pic, $ srcurl = '') sends graphic information to an account * Get_avatar ($ url) obtains the user's profile picture data * @ Author dodge * [Url = home. php?
