關注微信時獲取用戶信息

關注微信公共號時獲取用戶信息
只需獲取到 openID 便可經過 下面接口 獲取用戶信息 固然你也能夠經過網頁受權的方式拿到 openID

1 接口調用請求說明
2 http請求方式: GET https://api.weixin.qq.com/cgi-bin/user/info?access\_token=ACCESS\_TOKEN&openid=OPENID&lang=zh\_CN

　　

 1  private function _responseMsg() 
 2     {
 3         $post_str = file_get_contents('php://input');
 4         if (!empty($post_str)) {
 5             // 解析微信傳過來的 XML 內容
 6             $post_obj      = (array)simplexml_load_string($post_str, 'SimpleXMLElement', LIBXML_NOCDATA);
 7             $from_username = $post_obj['FromUserName'];
 8             $to_username   = $post_obj['ToUserName'];
 9             $MsgType       = $post_obj['MsgType'];    //消息類型，event
10             $Event         = $post_obj['Event'];      //事件類型，subscribe(訂閱)、unsubscribe(取消訂閱)
11             $EventKey      = $post_obj['EventKey'];   //掃碼關注時 帶的信息

這裏的 $post_obj['FromUserName'] 就是 當前用戶的 openID
