2;

    public function getJson($url){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($ch);
        curl_close($ch);
        return json_decode($output, true);
    }
//    获取用户信息
    function getUserInfo(Request $request)
    {

        $appid  = '';
        $secret  = '';
        $access_token = "";

        $code = $request->param('code');

            //第一步:取全局access_token
            $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$appid&secret=$secret";
            $token = $this->getJson($url);

　　　　　　　//第二步:取得openid
            $oauth2Url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$appid&secret=$secret&code=$code&grant_type=authorization_code";
            $oauth2 = $this->getJson($oauth2Url);

　　　　　　　//第三步:根据全局access_token和openid查询用户信息
            $access_token = $token["access_token"];
            $openid = $oauth2['openid'];
            $get_user_info_url = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=$access_token&openid=$openid&lang=zh_CN";
            $userinfo = $this->getJson($get_user_info_url);

            return $userinfo 
  }
