$ AppSecret = 'd4624c36333337af5443d ';
$ Callback = 'HTTP: // www.yun8888.net/weixin/'; // callback address

// Log on
Session_start ();
// ------- Generate a unique random string to prevent CSRF attacks
$ State = md5 (uniqid (rand (), TRUE ));
$ _ SESSION ["wx_state"] = $ state; // save to SESSION
$ Callback = urlencode ($ this-> callback );
$ Wxurl = "https://open.weixin.qq.com/connect/qrconnect? Appid = ". $ this-> AppID." & redirect_uri = {$ callback} & response_type = code & scope = snsapi_login & state = {$ state} # wechat_redirect ";
Header ("Location: $ wxurl ");Callback address If ($ _ GET ['state']! = $ _ SESSION ["wx_state"]) {
Exit ("5001 ");
}
$ AppID = 'wx33333333334d4 ';
$ AppSecret = 'd4624c363333330547af5443d ';
$ Url = 'https: // api.weixin.qq.com/sns/oauth2/access_token? Appid = '. $ AppID.' & secret = '. $ AppSecret.' & code = '. $ _ GET ['code'].' & grant_type = authorization_code ';

$ Ch = curl_init ();
Curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, FALSE );
Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, TRUE );
Curl_setopt ($ ch, CURLOPT_URL, $ url );
$ Json = curl_exec ($ ch );
Curl_close ($ ch );

$ Arr = json_decode ($ json, 1 );

// Obtain the access_token and openid
