php判断用户是否关注微信公众号

方法一：

<?php

    $access_token = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=XXXXXXXXXXXXXXXXXX&secret=XXXXXXXXXXXXXXXXXXXXXXXXXX";

    $access_msg = json_decode(file_get_contents($access_token));

    $token = $access_msg->access_token;

    $subscribe_msg = "https://api.weixin.qq.com/cgi-bin/user/info?access_token=$token&openid=$_GET[openid]";

    $subscribe = json_decode(file_get_contents($subscribe_msg));

    $gzxx = $subscribe->subscribe;

    if($gzxx === 1){

     echo "已关注";

    }else{

    echo "未关注"; 

 }

 

 

方法二：

< ? php

  

$access_token = $this - > _getAccessToken();

$subscribe_msg = 'https://api.weixin.qq.com/cgi-bin/user/info?access_token='.$access_token.'&openid='.$_SESSION['wecha_id'];

$subscribe = json_decode($this - > curlGet($subscribe_msg));

$zyxx = $subscribe - > subscribe;

  

if ($zyxx !== 1) {

 echo'未关注！';

}

private function _getAccessToken() {

 $where = array('token' = > $this - > token);

 $this - > thisWxUser = M('Wxuser') - > where($where) - > find();

 $url_get = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid='.$this - > thisWxUser['appid'].'&secret='.$this - > thisWxUser['appsecret'];

 $json = json_decode($this - > curlGet($url_get));

 if (!$json - > errmsg) {

 } else {

 $this - > error('获取access_token发生错误：错误代码'.$json - > errcode.',微信返回错误信息：'.$json - > errmsg);

 }

 return $json - > access_token;

}
