MethodNotAllowedHttpException in RouteCollection.p

问题:

I will get MethodNotAllowedHttpException when submitting a form in laravel

Html file

<form method="POST" action="/cards/{{$card->id}}/notes">
    <input name="_token" type="hidden" value="{{ csrf_token() }}"/>
    <textarea name="body" class="form-control"></textarea>
    <button type="submit">Add Note</button>
</form>

routes.php

Route::post('cards/{card}/notes','NotesController@store');

NotesController.php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;

class NotesController extends Controller
{
    public function store()
    {
        return request()->all();
    }
}

Make sure you don't have a route, say a Route::post with a parameter that lies in front of the route you are trying to hit.

For example:

Route::post('{something}', 'SomethingController@index');
Route::post('cards/{card}/notes', 'NotesController@store');

In this case, no matter what you try to send to the cards route, it will always hit the something route because {something} is intercepting cards as a valid parameter and triggers the SomethingController. Put the something route below the cards route and it should work.

MethodNotAllowedHttpException is thrown when no matching route (method and URI) was found, but a route with a matching URI but not matching method was found.

In your case, I guess the issue is because URI parameters differ between the route and the controller.

Here are two alternatives you can try:

1. Remove the parameter from your route:

Route::post('cards/notes','NotesController@store');

2. Add the parameter to your controller:

    public function store($card)
    {
        return request()->all();
    }

I have tried to solve this error in lumen and it took me quite a lot of time to figure out the problem. The problem is with laravel itself.

Sometimes if you have another route like GET device/{variable}, laravel stops in this first route...

So what you need to do is change the route POST device to POST device/add
