Laravel 5.2.36在RouteCollection.php第218行中的MethodNotAllowedHttpException: [英] Laravel 5.2.36 MethodNotAllowedHttpException in RouteCollection.php line 218:

问题描述

我对Laravel还是陌生的，正在尝试实现一个简单表单的发布请求.我一直在关注YouTube教程系列( laravel 5 |第3节|第4部分:路由POST请求)，但是在5:46分钟时，有一条通知，指出此方法仅适用于Laravel 5.2之前的版本.

Hi I am fairly new to Laravel and am trying to implement a post request for a simple form. I have been following a YouTube Tutorial series (laravel 5 | Section 3 | Part 4 Routing POST Requests) however at 5:46mins in, there is a notification that this method is only applicable to versions prior to Laravel 5.2.

我已经尝试编辑受保护的VerifyCsrfToken.php方法$ except = ['api/'];但这没什么区别.

I have tried to edit the VerifyCsrfToken.php method protected $except = ['api/']; but this makes no difference.

我的routes.php代码段:

My routes.php code snippet:

Route::post('/form-handler', function(\Illuminate\Http\Request $request){
    if(isset($request['option']) && $request['firstName'])
    {
        if(strlen($request['firstName']) > 0){
            return view('forms.formResults', ['action' => $request['option'], 'name' => $request['firstName']]);
        }
        return redirect()->back();
    }
    return redirect()->back(); // Return user back to the page they came from
})->name('form-handler');

我的welcome.blade.php代码段:

My welcome.blade.php code snippet:

<div class="form-group">
    <form action="{{route('form-handler')}}" method="post" class="form-control">
        <label for="select-action">Select an option:</label>
        <select id="select-action" name="option">
            <option value="option1">Option1</option>
            <option value="option2">Option2</option>
            <option value="option3">Option3</option>
        </select>
        <input type="text" name="firstName">
        <button type="submit">Submit Details</button>
        <input type="hidden" value="{{Session::token()}}" name="_token"> <!-- Laravel Security Measure, Note name must always be '_token'-->
    </form>
</div>

我的完整错误消息:

这种实施方法是完全无效还是仅需要几个星期?

Is this method of implementation completely invalid or does it just need a few tweeks?

最好，我想知道什么是用于检索表单数据的最佳发布方法，同时仍然可以保护您的站点免受跨站点请求伪造的侵害.

Preferably I would like to know what the optimal post method is for retrieving form data, while still protecting your site from cross-site request forgeries.

任何修复或替代解决方案将不胜感激.

Any fixes or alternate solutions will be much appreciated.

请随时询问我可能没有的任何资源.

Please feel free to ask for any resources I may have left out.

完整的route.php(请注意，我也尝试过将post方法添加到中间件路由组中):

Full routes.php (Note I have also tried adding the post method to the middleware route group):

    <?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

/* Route::get('/', function () {
    return view('home.welcome');
}); */

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

Route::resource('lists', 'ListsController');

Route::get('/contact/{firstName?}', function($firstName = null)
{
    return view('about.contact', ['firstName' => $firstName]);
})->name('contact');

Route::get('/blog', function()
{
    return view('blog.blog');
})->name('blog');

Route::group(['middleware' => 'auth'], function () {
    Route::post('/form-handler', function(\Illuminate\Http\Request $request){
        if(isset($request['option']) && $request['firstName'])
        {
            if(strlen($request['firstName']) > 0){
            return view('forms.formResults', ['action' => $request['option'], 'name' => $request['firstName']]); // You create the view
        }
        return redirect()->back();
    }
    return redirect()->back(); // Return user back to the page they came from
    })->name('form-handler');
});

推荐答案

已编辑答案-

我已经编辑了答案，以使代码更符合您的需要.代替使用isset，它使用验证，如果未设置选项，验证将不会停止运行代码.这也会在刀片视图上显示错误消息.

I have edited my answer to make cleaner code that has exactly what you need. instead of using isset, it uses validation that will not stop running the code if the options are not set. This will also display an error message on the blade view.

您的route.php文件应包含以下内容

Your routes.php file should contain the following

Route::post('/form-handler', 'formController@formHandle');

刀片"视图必须具有如下形式的表单

The Blade view must have a form that looks like this

@if (count($errors) > 0)
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
<div class="form-group">
    <form action="{{route('form-handler')}}" method="post" class="form-control">
        <label for="select-action">Select an option:</label>
        <select id="select-action" name="option">
            <option value="option1">Option1</option>
            <option value="option2">Option2</option>
            <option value="option3">Option3</option>
        </select>
        <input type="text" name="firstName">
        <input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
        <button type="submit">Submit Details</button>
        <input type="hidden" value="{{Session::token()}}" name="_token">
    </form>

表单控制器必须看起来像这样

The form controller must look like this

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Routing\Controller;

class FormController extends Controller
{
    /**
     * Logic Goes here.
     *
     * @param  Request  $request
     * @return Response
     */
    public function formHandle(Request $request)
    {   
        $this->validate($request, [
            'firstName' => 'required|min:1|max:255',
            'option' => 'required'
            ]);

            $data = $request;

            return view('forms.formResults')->compact($data);  
    }
}
