php - 如何在 Symfony 中调试 "MethodNotAllowedHttpException"？

Question

这个问题已经有答案了:

Symfony2 MethodNotAllowedHttpException on live server (3 个回答)

已关闭 5 年前。

我使用“添加产品”功能为我的网站创建了一个后端，但是当我添加它时，我没有在 table 上创建产品，并且出现此错误

我有这个错误:

Symfony \ Component \ HttpKernel \ Exception \
MethodNotAllowedHttpException
No message

我的表格:

@extends('admin.layout.admin')

@section('content')

	<h3>Aggiungi Prodotto</h3>

	<div class='row'>
			<div class="col-md-8 col-md-offset-2">

				{!! Form::open(['route'=>'product.create','method'=>'post', 'files'=>true]) !!}

			<div class="form-group">
				{{ Form::label('nome', 'Nome') }}
				{{ Form::text('nome', null, array('class'=> 'form-control')) }}
			</div>

			<div class="form-group">
				{{ Form::label('descrizione', 'Descrizione') }}
				{{ Form::text('descrizione', null, array('class'=> 'form-control')) }}
			</div>

			<div class="form-group">
				{{ Form::label('prezzo', 'Prezzo') }}
				{{ Form::text('prezzo', null, array('class'=> 'form-control')) }}
			</div>

			<div class="form-group">
				{{ Form::label('category_id', 'Categoria') }}
				{{ Form::select('category_id',[1=>'Flauti'],null,['class'=> 'form-control','placeholder'=>'Seleziona Categoria']) }}

			</div>

			<div class="form-group">
				{{ Form::label('image', 'Image') }}
				{{ Form::file('image',array('class'=> 'form-control')) }}
			
			</div>

		{{ Form::submit('create', array('class'=>'btn btn-->default')) }}

		{!! Form::close() !!}

			</div> 

	</div>

Route::resource('product','ProductsController');
Route::resource('category','CategoriesController');

});

我的 Controller :

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Category;

class ProductsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        //
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        $categories=Category::pluck('nome','id');
        return view('admin.product.create',compact('categories'));
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $formInput=$request->except('image');
        //image upload
        $image=$request->image;
        if ($image){
            $imageName=$image->getClientOriginName();
            $image->move('image',$imageName);
            $formInput['image']=$imageName;
    }
        Product::create($formInput);
        return redirect()->route('admin.index');
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.

    /**

    public function destroy($id)
    {
        //
    }
}

Answer 1

请更改表单中的以下行

{!! Form::open(['route'=>'product.create','method'=>'post', 'files'=>true]) !!}

到

{!! Form::open(['route'=>'product.store','method'=>'post', 'files'=>true]) !!}

基本上，创建路由是为了在使用资源时显示表单。但是，当您想提交表单时，您需要提交到 .store，或者如果它是编辑表单，则提交到 .update 路由。
