自定义 thinkphp5.0全局异常报错，继承基类\exception解决

 

情景介绍：url请求是get方式，此次报错是测试post请求，异常返回错误信息是否正确，结果异常返回信息有误，返回信息不正确。

以下下报错信息，显示  自定义全局异常报错信息是传入HttpException参数给app\lib\exception\ExceptionHandle::render() 方法（本应传入think\Exception类型的参数），结果异常信息不能自动转换成正确的信息，查看think\Exception 和 HttpException 两个class类，都同时继承了\exception基类,也就是think\Exception 和 HttpException 两个class类并没有继承关系，二者互不关联，所以参数类型不能识别，将app\lib\exception\ExceptionHandle::render()的参数改为以基类的方式参数传入，就可解决此问题。
