 1 //接收微信端的api，返回用户openid
 2     public function wx_api(){
 3 
 4         $app_id = 'wx3472f272ef0129dc'; //更换新小程序时，应该把小程序开发工具（用appid登录的小程序）+后台服务这边的appid都要更新一下
 5         $secret = '8cd796a81977df7407ed0908a1492f2e';
 6         $js_code = $_GET['js_code']; //小程序前端随机生成
 7 
 8         //微信api
 9         $url="https://api.weixin.qq.com/sns/jscode2session?appid=".$app_id."&secret=".$secret."&js_code=".$js_code."&grant_type=authorization_code";
