判断微信用户是否关注微信号

1.先获取公众号的access_token

private $appid=‘‘;
private $secret=‘‘;
private function getAccessToken() { // access_token 应该全局存储与更新,以下代码以写入到文件中做示例 $data = S(‘access_token‘); if ($data[‘expire_time‘] < time()) { // 如果是企业号用以下URL获取access_token // $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret"; $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$this->appid."&secret=".$this->secret; $res = json_decode($this->http_curl($url),true); $access_token = $res[‘access_token‘]; if ($access_token) { $data[‘expire_time‘] = time() + 7000; $data[‘access_token‘] = $access_token; S(‘access_token‘,$data); } } else { $access_token = $data[‘access_token‘]; } return $access_token; }

2.再根据"https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$accessToken."&openid=".$openid;  调用curl,根据返回的结果集里的subscribe的状态进行判断

 1     public function attention(){
 2         $openid=$_SESSION[‘weinfo‘][‘openid‘];
 3         // 获取公众号的access_token,此access_token不是用户授权后的access_token
 4         $accessToken = $this->getAccessToken();
 5         $subscribe_msg = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$accessToken."&openid=".$openid;
 6         $subscribe_info = $this->http_curl($subscribe_msg);
 7         $subscribe_info = json_decode($subscribe_info);
 8         if($subscribe_info->subscribe){
 9             $msg[‘status‘]=1;
10         }else{
11             $msg[‘status‘]=0;
12         }
13         return $msg;
14     }
