身份验证失败导致 WSOD

Question

我正在使用 Larave 4.2，一切正常。如果我输入正确的凭据，我将被带到正确的 URL（带有身份验证过滤器的那个）。但是我目前遇到的问题是当其中一个字段输入不正确并且用户提交时会显示白屏。

我当然期望用户将被重定向回带有输入的登录页面并显示错误。

我已经检查了过滤器，很确定它仍然是 Laravel 附带的，没有任何改变。

我的路线

<?php

Route::get('login', function()
{
    // just a shortcut to redirec to /login into /cms/login : prevents redirect LOOP
    return Redirect::route('cms.login');
});

Route::group(array('prefix' => 'cms'), function()
{
    Route::get('/', function()
    {
        if (Auth::guest())
        {
            return Redirect::route('cms.login');
        }
        else
        {
            return Redirect::route('cms.home');
        }
    });

    Route::get('login', array(
        'as'   => 'cms.login',
        'uses' => 'CMSController@login'
    ));

    Route::post('login', array(
        'as'   => 'cms.postLogin',
        'uses' => 'CMSController@userLogin'
    ));

    Route::get('logout', array(
        'as'   => 'cms.logout',
        'uses' => 'CMSController@userLogout'
    ));

    Route::group(array('before' => 'auth'), function()
    {
        Route::get('home', array(
            'as'   => 'cms.home',
            'uses' => 'CMSController@home'
        ));

        Route::get('my-account', array(
            'as'   => 'cms.myaccount',
            'uses' => 'AccountsController@myAccount'
        ));

        Route::get('my-account/edit', array(
            'as'   => 'cms.edit-myaccount',
            'uses' => 'AccountsController@editMyAccount'
        ));

        Route::resource('accounts', 'AccountsController');
        Route::resource('products', 'ProductsController');
        Route::resource('news', 'NewsController');
        Route::resource('settings', 'SettingsController');

        Route::resource('testimonials', 'TestimonialsController');
        Route::resource('effects', 'EffectsController');

目前在您的代码中 Auth::attempt() 之后没有任何内容 - 所以如果 Auth 失败 - 它无处可去。

只需在 Auth::attempt() 后添加一个 return 即可使其生效

    if (Auth::attempt(array(
        'email'    => $user_credentials['email'],
        'password' => $user_credentials['password']), $remember_me))
    {
        return Redirect::route('cms.home');
    }

    return Redirect::route('cms.login')->withInput()->withErrors($errors);
