获取到需要的资源（文档和示例），取到appid（新建应用）和key
替换示例文件.html里的链接appid和js变量appid，设置callback_url成功支付回调链接
在应用那里配置接受支付消息的url，第四方将以post的方式访问（计算核对签名，判断支付状态）
通知客户人员帮你配置好通道
直接访问示例文件的.html，调用WP.click({参数})方法发起支付。
到用户指定的方式付款，付款成功后，第四方post方式访问接受url（应用配置的）
最后跳转到callback_url成功回调
因为laravel-wechat包，微信授权功能是用中间件Middleware的形式实现的
在同一个路由中，它是发起微信授权的发动者，同时也是微信授权成功的回调
所以，访问的都是同一个链接（路由），那么就要区分是要发起授权还是用户已经授权，内部是采用session的方式实现的，所以一定要开启session功能，授权路由需要放置在web中间件的路由组里面。
$sql = "call CreateExChange($num,$pihao)";
DB::connection('game-default')->select($sql);Laravel没有专门说提供运行存储过程的方法，我们可以直接使用select方法来调用原始的调用存储过程的sql语句
