Question

我正在跟随Laracasts的“Build Larabook from Scratch”系列我一遍又一遍地检查代码，但找不到我的错误。我可以注册一个用户，因此Auth :: login（$ user）可以工作，但我无法使Auth :: attempt（）工作。

我尝试了以下（以及更多）。我无法理解。

将用户移回app / models
使用更简单的用户模型（标准）
过去了3次视频，试图找出我是否犯了错误

如何调试此问题？！我想知道为什么Auth :: attempt（）失败!!

请帮忙！

我的登录路线

Route::post('login', [
    'as' => 'login_path',
    'uses' => 'SessionsController@store'
]);

我的SessionsController构造函数（）和store（）方法[记录暂时尝试解决此问题]

public function __construct(SignInForm $signInForm) {

    $this->signInForm = $signInForm;

    $this->beforeFilter('guest', ['except' => 'destroy']);
}
public function store() {
      $input = Input::only('email', 'password');

      Log::info('User tried to login with email => ' . Input::get('email') . ' and password => ' . Input::get('password'));

      $this->signInForm->validate($input);

      $info = [
          'email' => Input::get('email'),
          'password' => Input::get('password')
      ];

      if (Auth::attempt($info)) {
          Log::info('AUTH ATTEMPT was successful');
          // Add flash message "Welcome Back"
          return Redirect::intended('/statuses');
      } else {
          Log::info('AUTH ATTEMPT failed');
          return Redirect::to('login');
      }

    }

我的SignInForm.php

namespace Fujibook\Forms;
use Laracasts\Validation\FormValidator;

class SignInForm extends FormValidator {

    /**
     *Validation rules for the registration form
     * @var type 
     */
    protected $rules = [
        'email'     => 'required',
        'password'  => 'required'
    ];
}

我的create.blade.php

<h1>Sign In</h1>


{{ Form::open(['route' => 'login_path']) }}

<div class="form-group">
    {{ Form::label('email', 'Email:') }}
    {{ Form::email('email', null, ['class' => 'form-control', 'required' => 'required']) }}
</div>

<div class="form-group">
    {{ Form::label('password', 'Password:') }}
    {{ Form::password('password', null, ['class' => 'form-control', 'required' => 'required']) }}
</div>

<div class="form-group">

    {{ Form::submit('Sign In', ['class' => 'btn btn-primary']) }}
</div>

{{ Form::close() }}

最后，我的用户模型\ Fujibook \ Users

<?php

namespace Fujibook\Users;

use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

use Fujibook\Registration\Events\UserRegistered;

use Laracasts\Commander\Events\EventGenerator;
use Eloquent, Hash;

class User extends Eloquent implements UserInterface, RemindableInterface {

    use UserTrait,
        RemindableTrait,
            EventGenerator;

    /**
     * Which fileds that may be massassigned
     * 
     * @var type 
     */
    protected $fillable = ['username', 'email', 'password'];

    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = array('password', 'remember_token');

    /**
     * Passwords must always be used;
     * @param type $password
     */
    public function setPasswordAttribute($password){
        $this->attributes['password'] = Hash::make($password);
    }

    public function getAuthIdentifier() {
        return $this->getKey();
    }

    public function getAuthPassword() {
        return $this->password;
    }

    /**
     * Register a new user
     * @param type $username
     * @param type $email
     * @param type $password
     */
    public static function register($username, $email, $password) {
        $user = new static(
                compact('username', 'email', 'password')
                );

        // raise an event
        $user->raise(new UserRegistered($user));

        return $user;
    }

}

此外，我已在app / config / auth.php中的模型中设置模型

'model' => 'Fujibook\Users\User',

我可能还包括我的数据库迁移

public function up() {
    Schema::create('users', function(Blueprint $table) {
        $table->increments('id');
        $table->string('username')->unique();
        $table->string('email')->unique();
        $table->string('password', 70);
        $table->timestamps();
        $table->rememberToken();
    });
}

Answer 1

首先，您不需要再次使用Input::get()来获取电子邮件和密码。数据库中的字段名称是什么，用户名或电子邮件？我想象一下电子邮件，如果是这样，请将登录代码更改为：

public function store() {
  $input = Input::only('email', 'password');

  Log::info('User tried to login with email => ' . Input::get('email') . ' and password => ' . Input::get('password'));

  $this->signInForm->validate($input);

  if (Auth::attempt($input)) {
      Log::info('AUTH ATTEMPT was successful');
      // Add flash message "Welcome Back"
      return Redirect::intended('/statuses');
  } else {
      Log::info('AUTH ATTEMPT failed');
      return Redirect::to('login');
  }

}

Answer 2

我看到的问题只是这个

$info = [
      'username' => Input::get('email'),   <--- username = email???
      'password' => Input::get('password')
];

if (Auth::attempt($info)) {

不应该是这样的：

$info = [ 'email' => Input::get('email'), 'password' => Input::get('password') ];

Laravel4 - Auth :: attempt（）无法正常工作 - 无法登录（Larabook教程）
