使用"remember me"自动登录不起作用



我是Yii2的新手。我正在使用Yii 2基本模板。

我在我的web应用程序上实现了"记住我"功能,但它并没有像我想象的那样工作。我可以成功登录(勾选"记得我"复选框)。但在关闭浏览器并再次打开网站后,我没有登录,而是重定向到登录页面。

我在配置文件中将enableAutoLogin设置为true

'user' => [
        'identityClass' => 'appmodelsUser',
        'enableAutoLogin' => true,
         'authTimeout' => 86400,
    ],

1.在用户模型中执行此操作(如果使用任何其他模型登录,则使用该模型)。

将其添加到rules 之前

public $rememberMe = true;

并在您的模型中定义

public function login()
{
     if ($this->validate()) {
         return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600*24*30 : 0);
     }
     return false;
}

2.现在在您的视图页面中执行此操作

 <?= $form->field($model, 'rememberMe')->checkbox(['template' => "<div class="col-lg-offset-1 col-lg-3">{input} {label}</div>n<div class="col-lg-8">{error}</div>"]) ?>

确保您的用户模型已经实现了yiiwebIdentityInterface,并且它具有以下方法

  1. findIdentity()
  2. findIdentityByAccessToken()
  3. getId()
  4. getAuthKey()
  5. validateAuthKey()

    使用yii\db\ActiveRecord;

使用yii\web\IdentityInterface;

class User extends ActiveRecord implements IdentityInterface
{
    public static function tableName()
    {
        return 'user';
    }
    /**
     * Finds an identity by the given ID.
     *
     * @param string|integer $id the ID to be looked for
     * @return IdentityInterface|null the identity object that matches the given ID.
     */
    public static function findIdentity($id)
    {
        return static::findOne($id);
    }
    /**
     * Finds an identity by the given token.
     *
     * @param string $token the token to be looked for
     * @return IdentityInterface|null the identity object that matches the given token.
     */
    public static function findIdentityByAccessToken($token, $type = null)
    {
        return static::findOne(['access_token' => $token]);
    }
    /**
     * @return int|string current user ID
     */
    public function getId()
    {
        return $this->id;
    }
    /**
     * @return string current user auth key
     */
    public function getAuthKey()
    {
        return $this->auth_key;
    }
    /**
     * @param string $authKey
     * @return boolean if auth key is valid for current user
     */
    public function validateAuthKey($authKey)
    {
        return $this->getAuthKey() === $authKey;
    }
}

登录中使用"记住我"

1-使用此链接创建您的身份类:http://www.yiiframework.com/doc-2.0/guide-security-authentication.html

2-将此行添加到配置文件:

'components' => [
    'user' => [
        'enableAutoLogin' => true, /* Whether to enable cookie-based login. */
    ],
], 

3-验证登录表单后使用此代码:

/* If [[enableSession]] is `true`:
- the identity information will be stored in session and be available in the next requests
- in case of `$duration == 0`: as long as the session remains active or till the user closes the browser
- in case of `$duration > 0`: as long as the session remains active or as long as the cookie
  remains valid by it's `$duration` in seconds when [[enableAutoLogin]] is set `true`.
  */
$duration = $this->remember ? (30 * 24 * 3600) : 0;
Yii::$app->user->login($user, $duration);
