Laravel 5.2 NotFoundHttpException in RouteCollection.php 第 161 行错误

Question

我正在关注 tuts+ 视频系列以开发电子商务网络应用程序。我几乎完成了它，但我在商店部分遇到了一个问题。我在/store 向最终用户的路线上显示所有产品的列表，我这样做了，但现在我要建立的是每个产品的单一视图页面。简单地说，当我在商店页面上显示所有产品时，我希望每个产品都与他自己的单页视图相关联，即价格、图片和有关该特定帖子的其他数据。我关注了视频，但是当我尝试访问产品的单个页面时，它会引发以下错误。

错误：

存储所有产品或展示的索引文件：

    @foreach($products as $product)
                        <div class="col-md-4 col-lg-4 col-sm-12">
                                <li>{!! $product->title  !!} - ({!! $product->price !!})</li>
                                <p> {!! $product->description !!}</p>
                                <a href="store/view/{!! $product->id !!}">
                                    {!! Html::image($product->image ,$product->title) !!}</p>
                                </a>        
                              {!! Form::close() !!}
                         </div>
   @endforeach

View.blade.php 或产品单页：

{!! $product->title !!} <br>
{!! $product->description !!} <br>
{!! $product->image !!}

StoreController 代码：

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Category;
use App\product;
use View;
use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Redirect;

class StoreController extends Controller
{

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return View::make('store.index')->with('products', product::take(4)->orderBy('created_at','DESC')->get());
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return View::make('InsertCategory');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response

    public function store(Request $request)
    {
            $category = new Category;
            $category->name = Input::get('name');
            $category->save();      
            return Redirect::to('admin/categories')->with('message', 'Category Created');

    }

    /**

     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        return View::make('store.view')->with('product', product::find($id));
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        $category = Category::find(Input::get('id'));
        var_dump($input);
        if($category){
            $category->delete();
            return Redirect::to('admin/categories');
        }
    }
}

Routes.php：

Route::get('/', 'StoreController@index');
Route::get('/admin', function () {
    return view('welcome');
});
Route::resource('store', 'StoreController');
Route::resource('admin/categories', 'CategoriesController');
Route::resource('admin/products', 'ProductsController');

Answer 1

在您的商店索引刀片中，您没有使用相对链接，因此它将 store/view/{!! $product->id !!} 附加到当前 url（没有 QS）是什么。

如果您在该 href 的开头添加 / 可能会解决您的问题。您的商店控制器中似乎也没有 view 方法，请尝试将其更改为 show

@foreach($products as $product)
    <div class="col-md-4 col-lg-4 col-sm-12">
        <li>{!! $product->title  !!} - ({!! $product->price !!})</li>
        <p> {!! $product->description !!}</p>
        <a href="/store/{!! $product->id !!}">
            {!! Html::image($product->image ,$product->title) !!}
        </a>
    </div>
@endforeach

Answer 2

如果你拼错了路线名称，这个异常很容易重现：

NotFoundHttpException in RouteCollection.php

好像没有这样的路线。

试试

php artisan route:list

问题可能是您拼错了路线名称。 可能是aricles 而不是articles 之类的东西。

Answer 3

这是因为您没有调用要执行的方法/函数。例如，在您的“StoreController”上，您将执行您的Index 你应该打电话给你的routes.php

喜欢这个

Route::resource('store', 'StoreController@index');
