Question

我刚刚开始使用一年的Laravel项目为我的团契而且阻碍进步的主要障碍就在于此。任何帮助将不胜感激。下面的故事。

Laravel启动并运行后我尝试登录，我收到此错误：

Class User contains 3 abstract methods and must therefore be declared abstract or
implement the remaining methods 
(Illuminate\Auth\UserInterface::getRememberToken, 
Illuminate\Auth\UserInterface::setRememberToken,
Illuminate\Auth\UserInterface::getRememberTokenName)

我相信这可以通过http://laravel.com/docs/upgrade#upgrade-4.1.26修复，因此我按照建议将以下几行添加到用户：

public function getRememberToken(){ return $this->remember_token; }
public function setRememberToken($value){ $this->remember_token = $value; }
public function getRememberTokenName(){ return 'remember_token'; }

这消除了错误，但我仍然无法登录。我将使用正确的信息，但它似乎将我重定向回登录页面。经过进一步的研究，我发现我可能需要在我的数据库中有一个[b] remember_token [/ b]字段。我试图通过添加：

来添加和重新添加

$table->rememberToken(); 
[edit 2014-09-16, 07:05: added parens. they were in my code but forgotten in the post]

但是这产生了这个堆栈跟踪：

PHP Fatal error:  Call to undefined method Illuminate\Database\Schema\Blueprint::rememberToken() in /vagrant/www/vfamatching.dev/app/database/migrations/2013_11_01_033240_create_users_table.php on line 24

[编辑2014-09-16,07：05：试过观察者的回答] 在昨晚观察者的回答之后，我尝试通过替换

来使用他们的解决方案

$table->rememberToken(); with
$table->string('remember_token', 100);

迁移不再引发错误，但登录仍然挂起。另外，我应该指出Laravel建议使用rememberToken语法

我的登录路线

Route::get('login', array('as' => 'login', function () { return View::make('login'); }))->before('guest');
Route::post('login', 'UsersController@login');

和控制器方法

public function login() 
{ 
    $user = array(
        'email' => Input::get('email'),
        'password' => Input::get('password')
    );   
    if (Auth::attempt($user)) {
        Auth::user()->login();
        Auth::user()->lastLogin = Carbon::now();
        Auth::user()->save();
        if (Session::has('returnUrl'))
        {
            $intendedDestination = Session::get('returnUrl');
            Session::forget('returnUrl');
            return Redirect::to($intendedDestination)
            ->with('flash_success', 'You are successfully logged in.');
        }
        return Redirect::to('/')
            ->with('flash_success', 'You are successfully logged in.');
    }
    // authentication failure! lets go back to the login page
    return Redirect::route('login')
        ->with('flash_error', 'Your username/password combination was incorrect.')
        ->withInput();
}

Answer 1

'remember_token'只是一个varchar字段，应该像迁移中的任何其他字段一样创建：

$table->string('remember_token', 100)->nullable();

<强>更新

在回复您的评论时，您是正确的，架构构建器文档确实允许rememberToken方法，有趣的是upgrade guide没有提及它。它仅适用于Laravel v4.2及更高版本，截至本文撰写时，它只不过是上述代码的别名：

// File: /vendor/laravel/framework/src/Illuminate/Database/Schema/Blueprint.php
/**
 * Adds the `remember_token` column to the table.
 *
 * @return \Illuminate\Support\Fluent
 */
public function rememberToken()
{
    return $this->string('remember_token', 100)->nullable();
}

如果您使用4.2或更高版本，我将使用rememberToken函数而不是string函数来定义列，以防上述函数定义在以后的任何版本中发生更改。

至于您的登录尝试“挂起”，请使用相关的控制器方法更新您的问题，我可以帮助您。

Answer 2

也许这只是一个小错误，rememberToken是一种方法，应该像这样调用：

$table->rememberToken();

使用Remember Token进行Laravel登录/用户问题
