RouteCollection.php第201行中的Laravel 5 MethodNotAllowedHttpException:

Question

我的项目中有很多php文件:

admin.blade.php:此文件包含管理表单.

调用时显示以下错误:

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>

在route.php,此调用是:

Route::get('/admin',array('uses'=>'student@admin'));

这是函数 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.');
    }
}

我不太了解创建管理区域,我只是想创建它.

Answer 1

我就是这样做的.

routes.php文件

Route::get('/admin', 'UsersController@getAdminLogin');
Route::get('/admin/dashboard', 'UsersController@dashboard');
Route::post('/admin', 'UsersController@postAdminLogin');

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() !!}

dashboard.blade.php

<h4 class="text-center">
    Welcome {{ Auth::user()->full_name }}
</h4>

UsersController.php

/**
 * Display the admin login form if not logged in,
 * else redirect him/her to the admin dashboard.
 *
 */
public function getAdminLogin()
{
    if(Auth::check() && Auth::user()->role === 'admin')
    {
        return redirect('/admin/dashboard');
    }
    return view('admin_login');
}

/**
 * Process the login form submitted, check for the
 * admin credentials in the users table. If match found,
 * redirect him/her to the admin dashboard, else, display
 * the error message.
 *
 */
public function postAdminLogin(Request $request)
{
    $this->validate($request, [
        'email'    => 'required|email|exists:users,email,role,admin',
        'password' => 'required'
    ]);

    $credentials = $request->only( 'email', 'password' );

    if(Auth::attempt($credentials))
    {
        return redirect('/admin/dashboard');
    }
    else
    {
        // Your logic of invalid credentials.
        return 'Invalid Credentials';
    }
}

/**
 * Display the dashboard to the admin if logged in, else,
 * redirect him/her to the admin login form.
 *
 */
public function dashboard()
{
    if(Auth::check() && Auth::user()->role === 'admin')
    {
        return view('admin.dashboard');
    }
    return redirect('/admin');
}

你的代码:

在routes.php,你只有1条路线,即

Route::get('/admin',array('uses'=>'student@admin'));

并且没有post方法的声明,因此,MethodNotAllowedHttpException

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.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);
    // ...
}

正如@Sulthan建议的那样,你应该使用Form Facade.你可以看看这个视频在Laracasts什么Form Facade是你应该如何使用它.

Answer 2

您post在表单中使用方法，但get在路由中使用方法。

因此，将方法更改为post您的路线

注意 ：

我建议您使用Laravel的默认表单开头，如下所示，这始终是最佳做法

{!! Form::open(array('url' => 'foo/bar')) !!}

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

提示 ：

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内容。

默认情况下，laravel 5中不包含Form Facade。您应通过以下方式安装

composer require "illuminate/html":"5.0.*"

并在app.php中进行更新。

我写了一个博客，其中简要介绍了此安装。
