微信access_token多业务统一调用

1.access_token.json文件 用于存储access_token

{"access_token": "16_DUMf8LJODBpD7q8yTQpDFZ1kHEzs6o-pbSzPtMVIgahBJTuIWv4tsgB8Boq5uYAbM_YAb-0eg-A2DNUPOeih-XQHzH9uMfFZ7DU2MLuV9fT4oQxOPgCd47zlDGJhAFAGJM", "expires_time": 1543041789}

 

2.token.php

用于读取access_token和刷新access_token

 

 

"Content-Type: text/html;charset=utf-8"); $ip=$_SERVER['REMOTE_ADDR']; //设置安全ip if($ip=="110.180.70.90"){ $res =file_get_contents('access_token.json'); $result = json_decode($res, true); $expires_time =$result["expires_time"]; $access_token =$result["access_token"]; if (time() > ($expires_time + 3600)){         $url ="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wx43333b9fe550&secret=30518e99f338cb1f8ecac3469204dac0";         $res =file_get_contents($url);         $result = json_decode($res, true);         $access_token =$result["access_token"];         $expires_time = time();         file_put_contents('access_token.json','{"access_token": "'.$access_token.'", "expires_time": '.$expires_time.'}');                echo '{"access_token":"'.$access_token.'","author":"wangsanqu"}';     }else{             echo '{"access_token":"'.$access_token.'","author":"wangsanqu"}';           } } else{      echo "403禁止调用api接口";exit(); }

 

 

3.在需要调用的地方进行调用

 

$url ="https://********/token.php";         $res =file_get_contents($url);         $result = json_decode($res, true);         $access_token =$result["access_token"];         $expires_time = time();
