在laravel 5中如何防止用户直接访问路径以及如何检查请求是空的？

问题描述：

Here are my routes in my laravel 5 application,

Route::get('demotest', 'HomeController@demo_test');

Route::post('demo_result', 'HomeController@demo_result');

In my first route view i have a from with action {{ url('demo_result') }} if a user submits the form it will post to my second route and everything working fine, here after submitting form my route changing to demo_result which is an post route.
Now the problem is if any user directly trying to access demo_result it is showing following error. So how to handle the issue. I tried to check whether the request is empty but no use. I am using use Illuminate\Http\Request; to handle request.

以下是我的laravel 5应用程序中的路线，
p>

   Route :: get（'demotest'，'HomeController @ demo_test'）; 
  code>  pre> 
 
   Route :: post（'demo_result'，'HomeController  @demo_result'）;  code> 
 

 
在我的第一个路线视图 strong>我有一个来自动作 {{url（'demo_result'）}  }  code>如果用户提交表格，它将发布到我的第二条路线并且一切正常，在提交表格之后我的路线改为 demo_result  code>这是一条后路线。
 
Now 问题是如果任何用户直接尝试访问 demo_result  code>，它会显示以下错误。  
如何处理问题。 我试图检查请求是否为空但没有用。 我正在使用使用Illuminate \ Http \ Request;  code>来处理请求。   p>

Use any instead of get or post and then by using isset you can write your own login. Try this Route::any();

答

Method not allowed means you haven't declared a GET method for your demo_result URL.

What you can do I think is just creating a new route

Route::get(demo_result', ...);

That point to a custom method in your controller that redirect the user to your form, like

public function getResult(){ return redirect('demo_form');

When you are not posting data and just visiting the page from your browser you are asking a different method, not what you have declared.

Another way is just to set up a 404 handler...

You can edit your Render Function in

app\Exceptions\handler.php

like:

public function render($request, Exception $exception)
    {   
         if($exception instanceof \Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException){
             return redirect('/');
         }

        return parent::render($request, $exception);
    }
