之前用`php`开发过微信公众号
首先需要登录公众号，启用服务器配置
填写链接
点击开发|接口权限|网页授权
因为用的是`laravel`框架
设置路由
```
Route::any('weixin/verify', 'API\WeixinController@index');
Route::any('weixin/oauth', 'API\WeixinController@oauth');
Route::any('weixin/qrcode/{game_id}', 'API\WeixinController@qrcode');
Route::any('weixin/checkunion', 'API\WeixinController@checkunion');
```
然后创建`controller`
```
httpGet($url),true);

$data['expire_time'] = time() + 7200;
$data['access_token'] = $access_token;

特别提示，路由方法为any，并且中间件去除csrf
