RouteCollection.php 第 219 行中的 MethodNotAllowedHttpException 错误 Lravel 5.2

Question

使用 Laravel 5.2 开发电子商务应用程序！我刚刚添加了一个用于将类别插入数据库的视图，但是当我点击提交时，它会引发以下错误。

PS：在 stackoverflow 上尝试了所有答案，但都没有奏效！

错误：

查看代码：

      {!! Form::open(array('url' => 'http://localhost/ecom/admin/categories/create' , 'method' => 'post')) !!}
      <input type="hidden" name="_token" value="{{ csrf_token() }}">

                          <div class="form-group">
                            <label for="username">Category Name:</label>
                            <input type="username" class="form-control" name="name" id="name">
                          </div>    
                          <button type="submit" class="btn btn-default">Submit</button>
   {!! Form::close() !!}

模型在这里：

<?php

    namespace App;

    use Illuminate\Database\Eloquent\Model;

        class Category extends Model
        {
            protected $fillable = array('name');
            public static $rules = array('name' => 'required|min:3');
        }

控制器代码：

    <?php

    namespace App\Http\Controllers;
    use Illuminate\Http\Request;
    use App\Http\Requests;
    use View;
    use Illuminate\Support\Facades\Input;
    class CategoriesController extends Controller
    {

        /**

        public function index()
        {
            return View::make('categories.index')->with('Categories', Category::all());
        }

        /**

        public function create()
        {
            return View::make('InsertCategory');
        }

        /**

        public function store(Request $request)
        {
            $validator = Validator::make(Input::all(), Category::$rules);
            if($validator->passes()){
                $category = new Category;
                $category->name = Input::get('name');
                $category-save();

                return Redirect::to('admin/categories/index')->with('message', 'Category Created');
            }
            return Redirect::to('admin/categories/index')->with('message', 'Category Created')->withErrors($validator)->withInput();
        }

        /**

        public function show($id)
        {
            //
        }

        /**

         *
         * @param  int  $id
         * @return \Illuminate\Http\Response
         */
        public function edit($id)
        {
            //
        }

        /**

        public function update(Request $request, $id)
        {
            //
        }

         */
        public function destroy($id)
        {
            //
        }
    }

ROUTES.PHP

<?php

/*

| Routes File
|--------------------------------------------------------------------------
|
| Here is where you will register all of the routes in an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::resource('admin/categories', 'CategoriesController');

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| This route group applies the "web" middleware group to every route
| it contains. The "web" middleware group is defined in your HTTP
| kernel and includes session state, CSRF protection, and more.

*/

Route::group(['middleware' => ['web']], function () {
    //
});

Answer 1

您应该在提交表单时使用{!! Form::open(array('url' => 'http://localhost/ecom/admin/categories')) !!}。

根据 RESTful 资源控制器，表单操作的 URL 将是主路由，而不是 /store 或 /create。

Answer 2

也许对你有帮助：

例子：

 <form id="categoryForm" method="post" action="{{ route('categories.store') }}"/>

店铺路线：

Route::resource('categories', 'CategoryController');

控制器：

 public function store(Request $request)
{

    $id = (int)$request->get("id", 0);

    $validator = Categories::validator($request->all(), $id);
    if ($validator->fails()) {
        return redirect()->back()
            ->withErrors($validator->getMessageBag())
            ->withInput($request->all());
    }

    try {
        Categories::updateOrCreate([
            'id' => $id,
        ], [
            'name'   => $request->get('name'),
            'status' => $request->get('status')
        ]);

        return redirect()->route('categories.index')->with('flash_success', 'Category data saved!');
    } catch (\Exception $e) {

        return redirect()->route('categories.create')->with('flash_danger', 'Category data not saved!');
    }
}
