Lavavel 5.2.36 RouteCollection.php中的MethodNotAllowedHttpException行218： [英] Lavavel 5.2.36 MethodNotAllowedHttpException in RouteCollection.php line 218:
问题描述
您好，我对Laravel相当陌生，并且正在尝试实施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分46秒的时间内，有一个通知，此方法仅适用于Laravel 5.2之前的版本。
I试图编辑VerifyCsrfToken.php方法protected $ except = ['api /'];但这没什么区别。
我的routes.php代码片段：
Route :: post（'/ form-handler'，function（\Illuminate\Http\Request $ request）{
if（isset（$ request ['option']）&& $请求['firstName']）
{
if（strlen（$ request ['firstName']）> 0）{
return view（'forms.formResults'，['action' => $ request ['option']，'name'=> $ request ['firstName']]）;
}
return redirect（） - > back（）;
）
return redirect（） - > back（）; //将用户返回到它们来自的页面
}） - > name（'form-handler'）;
我的welcome.blade.php代码片段：
< div class =form-group>
< form action ={{route（'form-handler'）}}method =postclass =form-control>
< label for =select-action>选择一个选项：< / label>
< select id =select-actionname =option>
< option value =option1> Option1< / option>
< option value =option2> Option2< / option>
< option value =option3> Option3< / option>
< / select>
< input type =textname =firstName>
< button type =submit>提交详情< / button>
< input type =hiddenvalue ={{Session :: token（）}}name =_ token> <！ - Laravel安全措施，注意名称必须始终为'_token' - >
< / form>
< / div>

这种实现方法完全无效还是只需要一些tweeks？ p>
最好我想知道什么是检索表单数据的最佳后处理方法，同时还能保护您的网站免受跨网站请求伪造。
任何修补程序或备用解决方案都将非常感谢。

编辑答案 -
b我编辑了我的答案，使其更清晰，代码完全符合您的需求。而不是使用isset，它使用的验证不会停止运行代码，如果没有设置选项。这将在刀片视图中显示错误消息。
您的routes.php文件应包含以下内容：
Route :: post（'/ form-handler'，'formController @ formHandle'）;
刀片视图必须具有如下形式
@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 =postclass =form-control>
< label for =select-action>选择一个选项：< / label>
< select id =select-actionname =option>
< option value =option1> Option1< / option>
< option value =option2> Option2< / option>
< option value =option3> Option3< / option>
< / select>
< input type =textname =firstName>
< input type =hiddenname =_ tokenvalue =<？php echo csrf_token（）;？>>
< button type =submit>提交详情< / button>
< input type =hiddenvalue ={{Session :: token（）}}name =_ token>
< / form>
表单控制器必须像这样
<？php
namespace App \Http\Controllers;
使用Illuminate \Http\Request;
使用Illuminate\Routing\Controller;
类FormController扩展Controller

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

Is this method of implementation completely invalid or does it just need a few tweeks?
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.
Any fixes or alternate solutions will be much appreciated.
Please feel free to ask for any resources I may have left out.
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' => $request['firstName']]); // You create the view
}
return redirect()->back();
}
return redirect()->back(); // Return user back to the page they came from
})->name('form-handler');
});
Edited answer --
I have edited my answer to make cleaner code that has exactly what you need. instead of using isset, it uses validation that will not stop running the code if the options are not set. This will also display an error message on the blade view.
Your routes.php file should contain the following
Route::post('/form-handler', 'formController@formHandle');
The Blade view must have a form that looks like this
@if (count($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>
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);
}
}
