【问题描述】：
正如标题所示，我无法使 delete() 选项起作用。我在网上查了很多帖子，但没有正确的答案。 我正在使用带有 Homestead 的 Laravel 5.5（一周前安装，最新版本左右）。
让我给你一些代码，我真的希望有人能够帮助我。
这让我头疼，奥氮平快用完了。请告诉我我做错了什么，如果有什么遗漏，请告诉我！
我想以管理员身份删除一个页面，但我 Laravel 似乎没有授权我并给我这个错误：
protected function methodNotAllowed(array $others)
{
throw new MethodNotAllowedHttpException($others);
}
这是我的控制器：
<?php
namespace App\Http\Controllers\Admin;
use Auth;
use App\Page;
use App\Http\Requests\WorkWithPage;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class PagesController extends Controller
{
public function __construct() {
$this->middleware('admin');
$this->middleware('can:manageUsers,App\User');
}
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
if (Auth::user()->isAdmin()) {
$pages = Page::paginate(20);
} else {
$page = Auth::user()->pages()->paginate(5);
}
return view('admin.pages.index', ['pages' => $pages]);
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
return view('admin.pages.create')->with(['model' => new Page()]);
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(WorkWithPage $request)
{
Auth::user()->pages()->save(new Page($request->only([
'title','url','content'])));
return redirect()->route('pages.index')->with('status', 'Pagina succesvol aangemaakt');
}
/**
* Show the form for editing the specified resource.
*
* @param \App\Page $page
* @return \Illuminate\Http\Response
*/
public function edit(Page $page)
{
if(Auth::user()->cant('update', $page)){
return redirect()->route('pages.index')->with('status', 'Pagina succesvol aangepast');
}
return view('admin.pages.edit', ['model' => $page]);
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param \App\Page $page
* @return \Illuminate\Http\Response
*/
public function update(WorkWithPage $request, Page $page)
{
if(Auth::user()->cant('update', $page)){
return redirect()->route('pages.index')->with('status', 'Dat mag jij niet');
}
$page->fill($request->only([
'title','url','content'
]));
$page->save();
return redirect()->route('pages.index')->with('status', 'Pagina succesvol aangepast');
}
/**
* Remove the specified resource from storage.
*
* @param \App\Page $page
* @return \Illuminate\Http\Response
*/
public function destroy(Page $page)
{
if(Auth::user()->cant('delete', $page)){
return redirect()->route('pages.index')->with('status', 'Hey knul! Pssst! Wegwezen!');
}
$page->id->delete();
return redirect()->route('pages.index')->with('status', 'Page has been deleted.');
}
}
这是我的索引页面（后端的管理索引中的索引：
@extends('layouts.app') @section('content')
<div class="container">
@if (session('status'))
<div class="alert alert-info">
{{ session('status') }}
</div>
@endif
<a href="{{ route('pages.create')}}" class="btn btn-primary">Nieuwe pagina</a>
<br>
<br>
<table class="table">
<thead>
<tr>
<th>Naam</th>
<th>URL</th>
<th>Opties</th>
</tr>
</thead>
@foreach($pages as $page)
<tr>
<td>
<a href="{{ route('pages.edit', ['page' => $page->id]) }}">{{ $page->title }}</a>
</td>
<td>{{ $page->url }}</td>
<td class="text-right">
<a href="{{ route('pages.destroy', ['page' => $page->id])}}" class="btn btn-danger delete-link" data-message="Are you sure you want to delete this page?"
data-form="delete-form">
Delete
</a>
</td>
</tr>
@endforeach
</table>
{{$pages->links()}}
</div>
<form id="delete-form" action="" methode="POST">
{{method_field('DELETE')}}
{!! csrf_field() !!}
</form>
@endsection
然后是路线：
<?php
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function () {
return view('welcome');
});
Auth::routes();
Route::get('/admin', function() {
return view('admin.index');
})->middleware('admin');
Route::resource('/admin/pages', 'Admin\PagesController', ['except' => ['show']]);
Route::resource('/admin/blog', 'Admin\BlogController', ['except' => ['show']]);
Route::resource('/admin/users', 'Admin\UsersController', ['except' => ['create', 'store', '']]);
Route::get('/home', 'HomeController@index')->name('home');
然后是政策：
<?php
namespace App\Policies;
use App\User;
use App\Page;
use Illuminate\Auth\Access\HandlesAuthorization;
class PagePolicy
{
use HandlesAuthorization;
public function before($user, $ability) {
if ($user->isAdmin()) {
return true;
}
}
/**
* Determine whether the user can update the page.
*
* @param \App\User $user
* @param \App\Page $page
* @return mixed
*/
public function update(User $user, Page $page)
{
return $user->id = $page->user_id;
}
/**
* Determine whether the user can delete the page.
*
* @param \App\User $user
* @param \App\Page $page
* @return mixed
*/
public function delete(User $user, Page $page)
{
return $user->id = $page->user_id;
}
}
最后是中间件：
<?php
namespace App\Http\Middleware;
use Closure;
use Auth;
class AccessAdmin
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
if(Auth::check() && Auth::user()->hasAnyRole(['Super Admin','Admin'])) {
return $next($request);
}
return redirect('login');
}
}
更新：已修复！
在我改变的视图中：
@foreach($model as $post)
<tr>
<td>
<a href="{{ route('blog.edit', ['post' => $post->id]) }}">{{ $post->title }}</a>
</td>
<td>{{ $post->user()->first()->name }}</td>
<td>{{ $post->slug }}</td>
<td class="text-right">
<a href="{{ route('blog.destroy', ['blog' => $post->id])}}" class="btn btn-danger delete-link" data-message="Are you sure you want to delete this page?"
data-form="delete-form">
Delete
</a>
</td>
</tr>
@endforeach
</table>
{{$model->links()}}
</div>
<form id="delete-form" action="#" methode="POST">
{{ method_field('DELETE') }}
{!! csrf_field() !!}
</form>
收件人：
@foreach($pages as $page)
<tr>
<td>
<a href="{{ route('pages.edit', ['page' => $page->id]) }}">{{ $page->title }}</a>
</td>
<td>{{ $page->url }}</td>
<td class="text-right">
<form action="{{ route('pages.destroy', ['page' => $page->id]) }}" method="POST" class="btn btn-danger delete-link" >
<input type="submit" value="delete"/>
{{method_field('DELETE')}}
{!! csrf_field() !!}
</form>
</td>
</tr>
@endforeach
</table>
{{$pages->links()}}
【问题讨论】：
-
删除路由在哪里？欺骗？ stackoverflow.com/questions/31622818/…
-
这很有趣；我在网上看了一些教程，他们知道如何在没有的情况下做到这一点。我一直在搞乱路线，但没有结果。我都试图同时学习 PHP 作为 Laravel，所以无法真正理解这里的问题（在我解决这个问题后，我会更多地使用 PHP，然后是 Laravel）
-
想到的其他事情...发布到 GET 路线。相信日志，它会告诉你错误。
-
缺少路由似乎适用于编辑（和更新）。关于 POST for GET 部分：这在 tut 中有明确说明。所以我就这么做了
-
您已从 achor 调用删除。那会做
GET不是吗？您应该考虑使用表单和类似链接的提交按钮来达到预期的效果
