RouteCollection.php中的MethodNotAllowedHttpException第218行我该怎么办？

Question

我目前正在研究一个论坛系统（laravel 5.3），并且我得到一个错误，可能是因为我在路由设置中设置了错误。

<?php 

/* 
|-------------------------------------------------------------------------- 
| Web Routes 
|-------------------------------------------------------------------------- 
| 
| This file is where you may define all of the routes that are handled 
| by your application. Just tell Laravel the URIs it should respond 
| to using a Closure or controller method. Build something great! 
| 
*/ 

Route::get('/', 'IndexController@index')->name('index'); 

Auth::routes(); 

Route::get('/index', 'IndexController@index')->name('index'); 
Route::get('/thread/{id}', 'ThreadController@showThread')->name('thread_detail'); 
Route::get('/privacybeleid', 'PagesController@privacyPolicy'); 
Route::get('/over-ons', 'PagesController@about'); 

Route::group(['middleware' => 'auth'], function() { 

Route::get('/thread/nieuw', 'ThreadController@showForm')->name('thread_form'); 
Route::post('/thread', 'ThreadController@create')->name('create_thread'); 
Route::post('/thread/{id}/reply', 'CommentController@create')->name('create_comment'); 
}); 

当我想看到一个线程（website.com/thread/{id}），然后我没有得到任何错误，一切正常，因为它应该。但是，当我想在主题上添加新评论（website.com/thread/{id}/reply）或创建新主题（website.com/thread/nieuw）时，出现以下错误：

MethodNotAllowedHttpException in RouteCollection.php line 218:

我试图改变路线::得到到路线::后（反之亦然），但后来我得到另一个错误。

当我访问website.com/thread/nieuw时，我什么都看不到（页面不存在）。即使我有一个会话（登录）。

顺便说一下：有关于routes/web.php的提示吗？让我知道

注：我是荷兰人如此 “的Nieuw” 是指 “新”

Answer 1

尝试把这个路线：

Route::post('/thread/{id}/reply', 'CommentController@create')->name('create_comment'); 

这个之前：

Route::get('/thread/{id}', 'ThreadController@showThread')->name('thread_detail'); 

Answer 2

<?php 

namespace App\Http\Controllers; 

use Illuminate\Http\Request; 

use Auth; 
use App\Http\Requests; 
use App\Thread; 
use App\Comment; 

class CommentController extends Controller 
{ 
    public function create($id, Request $req) 
    { 
     $user = Auth::user(); 
     $thread = Thread::findOrFail($id); 
     $body = $req->get('body'); 
     $comment = new Comment([ 
      'body' => $body 
     ]); 
     $comment->user_id = $user->id; 
     $thread->comments()->save($comment); 
     return redirect()->route('thread_detail', ['id' => $thread->id]); 
    } 
} 

我的评论控制器

您可能需要检查编辑表单方法

{{ Form::open(['class' => 'form-horizontal', 'route' => ['create_comment', $thread->id], 'method' => 'PUT']) }}
