Laravel 5.2 MethodNotAllowedHttpException

Question

我得到MethodNotAllowedHttpException錯誤在我的Laravel 5.2項目，而我正在添加添加評論部分。

這裏是我的路線：

Route::post('/posts/{post}/comments', 'CommentsController@store'); 

這裏是我的CommentsController：

<?php 

namespace App\Http\Controllers; 

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

class CommentsController extends Controller 
{ 
    public function store(Post $post) 
    { 
     Comment::create([ 
      'body' => request('body'), 
      'post_id' => $post->id 
      ]); 

     return back(); 
    } 
} 

，這裏是我的觀點：

@extends('layouts.master') 
@section('content') 
<div class="col-sm-8 blog-main"> 
    <h1>{{ $post->title }}</h1> 
    {{ $post->body }} 
    <hr> 
    <h5>Comments</h5> 
    <div class="comments"> 
     <ul class="list-group"> 
      @foreach ($post->comments as $comment) 
      <li class="list-group-item"> 
      <strong> 
       {{ $comment->created_at->diffForHumans() }}: &nbsp; 
      </strong> 
      {{ $comment->body }} 
      </li> 
      @endforeach 
     </ul> 
    </div> 
    <hr> 
    <!-- Add Comment --> 
    <div class="card"> 
     <div class="card-block"> 
      <form method="POST" action="/blog/public/posts/{{ $post->id }}/comments" > 
       <div class="form-group"> 
        <textarea name="body" placeholder="Your Comment" class="form-control"></textarea> 
       </div> 
       <div class="form-group"> 
        <button type="submit" class="btn btn-primary">Add Comment</button> 
       </div> 
      </form> 
     </div> 
    </div> 
</div> 
@endsection 

變量$post和$comment成功地傳遞給查看檢索內容和評論工作正常，但是當我嘗試提交新評論時，我收到了MethodNotAllowedHttpException。

Answer 1

1. 提供您的航線名稱

   Route::post('/posts/{post}/comments', 'CommentsController@store')->name('comments.create'); 
   

2. 添加CSRF令牌和使用輔助方法route()來訪問你的形式

   <form method="POST" action="{{ route('comments.create', ['post' => $post->id]) }}" > 
       {{ csrf_field() }} 
       <div class="form-group"> 
        <textarea name="body" placeholder="Your Comment" class="form-control"></textarea> 
       </div> 
       <div class="form-group"> 
        <button type="submit" class="btn btn-primary">Add Comment</button> 
       </div> 
   </form> 
   

3. 路線更改函數簽名

   public function store($post) 
   { 
       Comment::create([ 
        'body' => request('body'), 
        'post_id' => $post 
       ]); 
   
       return back(); 
   } 
   

Answer 2

表單動作應該是這樣的

/posts/{{ $post->id }}/comments
