返回文件流，问价不存在，第一次报错，第二次才404
1、先执行以下文件存在代码，没有问题
<?php
namespace app\controller;
use support\Request;
class FooController
{
public function hello(Request $request)
{
return response()->file(public_path() . '/favicon.ico');
}
}
2、再修改为以下不存在的文件代码，第一次执行报错，第二次执行才是404
<?php
namespace app\controller;
use support\Request;
class FooController
{
public function hello(Request $request)
{
return response()->file(public_path() . '/favicon888.ico');
}
}

首先你文件不存在 filemtime肯定报错啊 自己判断下文件在不在
那为什么第一次访问报错，第二次访问才出现404；按照官方文档应该第一次访问就是自动返回404.如果文件不存在，会自动转为404响应
复现了一次, 应该是bug
