Question

我很难使用Laravel 4 Auth :: attempt方法，按照正确的文档，阅读几个SO线程，但我仍然无法使其工作。

$userData = array('email' => 'admin@admin.com','password' => 'admin');
if(Auth::attempt($userData)){
    // redirect
}
else{
   echo 'Invalid';
}

每次都返回Invalid

现在我不确定究竟是什么原因。

在我的config / auth.php中，我有以下

<?php

   return array(
/*
|--------------------------------------------------------------------------
| Default Authentication Driver
|--------------------------------------------------------------------------
|
| This option controls the authentication driver that will be utilized.
| This drivers manages the retrieval and authentication of the users
| attempting to get access to protected areas of your application.
|
| Supported: "database", "eloquent"
|
*/

'driver' => 'eloquent',

/*
|--------------------------------------------------------------------------
| Authentication Model
|--------------------------------------------------------------------------
|
| When using the "Eloquent" authentication driver, we need to know which
| Eloquent model should be used to retrieve your users. Of course, it
| is often just the "User" model but you may use whatever you like.
|
*/

'model' => 'User',

/*
|--------------------------------------------------------------------------
| Authentication Table
|--------------------------------------------------------------------------
|
| When using the "Database" authentication driver, we need to know which
| table should be used to retrieve your users. We have chosen a basic
| default value but you may easily change it to any table you like.
|
*/

'table' => 'users',

/*
|--------------------------------------------------------------------------
| Password Reminder Settings
|--------------------------------------------------------------------------
|
| Here you may set the settings for password reminders, including a view
| that should be used as your password reminder e-mail. You will also
| be able to set the name of the table that holds the reset tokens.
|
*/
'reminder' => array(
    'email' => 'emails.auth.reminder', 'table' => 'password_reminders',
),
 );
 ?>

Answer 1

确保数据库中的密码字段有64个字符的空格。 varchar(64)

哈希需要64个字符，如果你的哈希密码在插入时被截断（因此无法正确验证密码），你就不会从laravel中得到错误。

Answer 2

@ eric-evans是对的。要在laravel 4中使用身份验证，必须使“用户”模型使用\ Illuminate \ Auth \ UserInterface接口，并实现方法

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

Answer 3

你能为你的模特展示代码吗？这些是用户模型中的一些内容，以便Auth工作。

<?php

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

    class User extends Eloquent implements UserInterface, RemindableInterface{

    protected $fillable = array('fname','lname','email','password','create_at','updated_at');

    /**
    * 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');

    /**
    * Get the unique identifier for the user.
    *
    * @return mixed
    */
    public function getAuthIdentifier()
    {
        return $this->getKey();
    }

    /**
    * Get the password for the user.
    *
    * @return string
    */
    public function getAuthPassword()
    {
        return $this->password;
    }

    /**
    * Get the e-mail address where password reminders are sent.
    *
    * @return string
    */
    public function getReminderEmail()
    {
        return $this->email;
    }
}

Answer 4

我也遇到了一些麻烦。我注意到的是，在我的用户模型中，我有：

protected $softDelete = true;

在数据库中，我有了deleted_at列，但它默认为零时间戳 - 0000-00-00 00:00:00。这导致无法找到记录，从而导致身份验证失败。

我必须修复迁移才能正确创建deleted_at列，如下所示：

public function up()
{
  Schema::create('users', function($t) {
    $t->increments('id');
    $t->string('first_name');
    $t->string('last_name');
    $t->string('username');
    $t->string('email');
    $t->string('password');
    $t->softDeletes();
    $t->timestamps();
  });
}

以下是有关软删除的文档：http://laravel.com/docs/eloquent#soft-deleting

Answer 5

Auth类需要一个名为id的列作为users表中的主键。

Answer 6

注意你的User表，密码字段是Hashed，原因是Auth :: attempt（$ credentials）; $ credentials-＆gt;密码评估哈希密码

Answer 7

检查您的密码是否经过哈希处理。它不应该是正常的文本..

Answer 8

您的代码正在窃听，因为您将错误的数组键传递给Auth::attempt()。该方法需要一个包含密钥用户名，密码的数组，并可选择记住。鉴于此，您的上述代码应为：

Route::post('login', function()
{
    $credentials = [
        'username' => 'admin@email.com',
        'password' => 'superSecretPassword'
    ];

    dd(Auth::attempt($credentials));
});
