关注微信时获取用户信息

关注微信公共号时获取用户信息
只需获取到 openID 即可通过下面接口获取用户信息当然你也可以通过网页授权的方式拿到 openID

1 接口调用请求说明
2 http请求方式: 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             // 解析微信传过来的 XML 内容
 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'];    //消息类型，event
10             $Event         = $post_obj['Event'];      //事件类型，subscribe(订阅)、unsubscribe(取消订阅)
11             $EventKey      = $post_obj['EventKey'];   //扫码关注时 带的信息

这里的 $post_obj['FromUserName'] 就是当前用户的 openID
