奇怪的错误“未定义路由”

Question

我正在学习 Laravel 5.4，但我无法解决这个问题。我像这样在视图刀片中添加了两条路线

<a href="{{ route('backend.blog.create') }}" class="btn btn-primary">Write post</a>

然后在我的路由 web.php 文件中我有

Route::resource('/backend/blog', 'Backend\BlogController');

在HomeController@index，我加载上面有按钮的索引页面，像这样

<?php

namespace App\Http\Controllers\Backend;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Post;

class BlogController extends BackendController
{
    protected $limit = 5;

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $posts     = Post::with('category', 'author')->latest()->paginate($this->limit);
        $postCount = Post::count();
        return view("backend.blog.index", compact('posts', 'postCount'));
    }
       ...

}

Backend 目录中的 HomeController 持有

<?php

namespace App\Http\Controllers\Backend;

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

class HomeController extends BackendController
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('backend.home');
    }
}

backend.home 上面的a href 会产生错误。为什么会这样？

完整的错误信息

ErrorException in UrlGenerator.php line 304:
Route [backend.blog.create] not defined. (View: /var/www/blog/resources/views/backend/home.blade.php)

Answer 1

Route::resource('/backend/blog', 'Backend\BlogController', [
    'names' => [
        'create' => 'backend.blog.create'
    ]
]);

route() 助手制作命名路由

路由

Route::POST("/backend/blog/create", "Backend\BlogController@create")->name("backend.blog.create");

在视图中

{{ route('backend.blog.create') }}
