问题描述
使用 AuthCheck 中间件并尝试在会话中检查 Has Username 但它给出错误错误说明如下
错误 错误异常 尝试读取字符串 LoginController 上的属性“headers” C:\xampp\htdocs\larave8auth\vendor\laravel\framework\src\Illuminate\Foundation\Http\Middleware\VerifyCsrftoken.PHP:191

解决方法
因为你的中间件只是返回一个字符串，而不是一个重定向。当您希望允许系统继续提前处理请求时，您确实会返回 $next($request); 或 return abort(404);。您的中间件必须返回一个 Response 对象，或 $next($request) :
public function handle(Request $request,Closure $next)
{
if (session()->has('username')) {
return $next($request);
} else {
return abort(404);
}
}
