Question

我的 Laravel 5.2 项目出现MethodNotAllowedHttpException错误，而我正在添加“添加评论”部分。

这是我的路线：

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

这是我的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();
   }
}

这是我的观点：

@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

变量$post和$comment成功传递到视图，因为检索内容和评论工作正常，但当我尝试提交新评论时，我得到MethodNotAllowedHttpException。

Answer 1

为您的路线提供名称

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

添加csrf令牌并使用帮助方法route()访问表单中的路径

<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>

更改您的功能签名

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

    return back();
}

Answer 2

您的表单操作应该是这样的

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