Laravel 5 MethodNotAllowedHttpException in RouteCollection.php line 201:
提问by deep singh
I have a number of php files in my project:
我的项目中有许多 php 文件：
admin.blade.php: this files contains the admin form.
admin.blade.php：此文件包含管理表单。
When called it show the following error:
调用时显示以下错误：
MethodNotAllowedHttpException in RouteCollection.php line 201
RouteCollection.php 第 201 行中的 MethodNotAllowedHttpException
<h2>Please Log In To Manage</h2>
<form id="form1" name="form1" method="post" action="<?=URL::to('/admin')?>">
<input type="hidden" name="_token" value="{{ csrf_token() }}">
User Name:<br />
<input name="username" type="text" id="username" size="40" />
<br /><br />
Password:<br />
<input name="password" type="password" id="password" size="40" />
<br />
<br />
<br />
<input type="submit" name="button" id="button" value="Log In" />
</form>
In route.php, this call is made:
在 中route.php，进行了此调用：
Route::get('/admin',array('uses'=>'student@admin'));
This is the function in student.php
这是中的函数 student.php
public function admin()
{
return View::make('student.admin');
$validator = Validator::make($data = Input::all() , User::rules());
if ($validator->fails())
{
return Redirect::back()->withErrors($validator)->withInput();
}
else
{
$check = 0;
$check = DB::table('admin')->get();
$username = Input::get('username');
$password = Input::get('password');
if (Auth::attempt(['username' => $username, 'password' => $password]))
{
return Redirect::intended('/');
}
return Redirect::back()->withInput()->withErrors('That username/password combo does not exist.');
}
}
I don't know much about creating an admin area, I am just trying to create it.
我不太了解创建管理区域，我只是想创建它。

This is how I do it.
我就是这样做的。
Routes.php
路由.php
Route::get('/admin', 'UsersController@getAdminLogin');
Route::get('/admin/dashboard', 'UsersController@dashboard');
Route::post('/admin', 'UsersController@postAdminLogin');
admin_login.blade.php
admin_login.blade.php
{!! Form::open(['url' => '/admin']) !!}
<div class="form-group">
{!! Form::label('email', 'Email Id:') !!}
{!! Form::text('email', null, ['class' => 'form-control input-sm']) !!}
</div>
<div class="form-group">
{!! Form::label('password', 'Password') !!}
{!! Form::password('password', ['class' => 'form-control input-sm']) !!}
</div>
<div class="form-group">
{!! Form::submit('Login', ['class' => 'btn btn-primary btn-block']) !!}
</div>
{!! Form::close() !!}

用户控制器.php

return view('admin_login');
}

public function postAdminLogin(Request $request)
{
$this->validate($request, [

if(Auth::attempt($credentials))

}
else
{
// Your logic of invalid credentials.
return 'Invalid Credentials';
}
}
/**

public function dashboard()

Your Code:
您的代码：
In routes.php, you have only 1 route, i.e.,
在 中routes.php，您只有 1 条路线，即
Route::get('/admin',array('uses'=>'student@admin'));
And there is no declaration of postmethod, hence, the MethodNotAllowedHttpException
并且没有post方法声明，因此，MethodNotAllowedHttpException
Also, in your controller, you are returning the view first and then processing the form which is not going to work at all. You first need to process the form and then return the view.
此外，在您的控制器中，您首先返回视图，然后处理根本不起作用的表单。您首先需要处理表单，然后返回视图。
public function admin(){
// Won't work as you are already returning the view
// before processing the admin form.
return \View::make(students.admin);
// ...
}
As @Sulthan has suggested, you should use Form Facade. You can check out this videoon Laracastsabout what Form Facadeis and how you should use it.
正如@Sulthan 所建议的，您应该使用Form Facade. 你可以在Laracasts上查看这个视频，了解它是什么以及你应该如何使用它。Form Facade
回答by Sulthan Allaudeen
You're using postmethod in the form but you're having getmethod in the routes.
您post在表单中使用方法，但get在路由中使用方法。
So, Change the method to postin your routes
因此，将方法更改为post您的路线
Note :
笔记 ：
I recommend you to make use of the default form opening of Laravel like the below given which is always the best practise
我建议您使用 Laravel 的默认表单打开方式，如下所示，这始终是最佳实践
{!! Form::open(array('url' => 'foo/bar')) !!}
{!! Form::close() !!}
Tips :
提示 ：
Read more on hereand try to debug such things by comparing the methods and routes.
在此处阅读更多内容，并尝试通过比较方法和路由来调试此类事情。
Form facade is not included in laravel 5 by default. You shall install it by
默认情况下，laravel 5 中不包含表单外观。你应该安装它
composer require "illuminate/html":"5.0.*"
and updating in the app.php.
并在 app.php 中更新。
I have written a blogwhich gives a breif about this installation.
我写了一篇博客，简要介绍了此安装。

In Routes web.phpYour code is
在路由web.php你的代码是
Route::get('/admin',array('uses'=>'student@admin'));
which is wrong. Actually submitting data in POST method its array of data so you need to route through post instead of get. so correct code is
这是错误的。实际上在 POST 方法中提交数据是它的数据数组，因此您需要通过 post 而不是 get 路由。所以正确的代码是
Route::post('/admin',array('uses'=>'student@admin'));

In routes.php, replace Route::getby Route::post.
在routes.php，替换Route::get为Route::post。
回答by Nehal Hasnayeen
You have no post route for your form data posting , use route match function for both http verb (get & post). use this
您的表单数据发布没有发布路由，请对 http 动词（get 和 post）使用路由匹配功能。用这个
Route::match(['get', 'post'], '/admin', 'student@admin');
Route::match(['get', 'post'], '/admin', 'student@admin');
Also you need to change your admin method,
您还需要更改管理方法，
public function admin(Request $request){
if($request->isMethod('get')){
return \View::make('student.admin');
} else {
// your validation logic
}
}
