最近做了一个微信公众号支付 ， 使用的是laravel 8 框架 ， 使用的是yansongda 2.0 版本，通过composer 下载（ composer require yansongda/pay:~2 ），一切就绪后咋们就开始吧！
我遇到的坑就是回调路由无效，当时支付了很多笔，也支付成功了，但是设置的回调方法一点作用都没用，根本不走设置的回调路由这个方法，另外也在微信商户平台也设置过回调路由地址了，并且请求参数回调路由可以走的通，到底怎么回事呢，我们来看看：
下面是当时设置的路由（因为使用的是get方式所以接收不到xml数据）：
这是我设置的回调地址：https://xxxxxx.com/api/wxpay/notify
路由设置
$router->get("api/wxpay/notify","LoginPaymentController@notifyCallback");//微信支付回调地址
然后看了日志目录地址（/storage/logs/lumen-2021-11-23.log） ， 说接收不到xml数据导致的
