你可以使用像 https://github.com/amnah/yii2-user.

或

如果您想编写自己的自定义脚本来管理用户，您可以覆盖 Yii2 identityClass.

If you want to write your own custom script to manage the users you can override Yii2 identityClass.

在配置的组件部分添加:

In the component section of your config add:

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

请注意，您的用户模型必须实现 yiiwebIdentityInterface

Please note that your user model MUST IMPLEMENT yiiwebIdentityInterface

这里是你可以用来实现数据库认证的模型类的例子

Here is the example of the model class that you can use to implement database authentication

namespace appmodels;

//appmodelsgiiUsers is the model generated using Gii from users table

use appmodelsgiiUsers as DbUser;

class User extends yiiaseObject implements yiiwebIdentityInterface {

public $id;
public $username;
public $password;
public $authKey;
public $accessToken;
public $email;
public $phone_number;
public $user_type;

/**
 * @inheritdoc
 */
public static function findIdentity($id) {
    $dbUser = DbUser::find()
            ->where([
                "id" => $id
            ])
            ->one();
    if (!count($dbUser)) {
        return null;
    }
    return new static($dbUser);
}

/**
 * @inheritdoc
 */
public static function findIdentityByAccessToken($token, $userType = null) {

    $dbUser = DbUser::find()
            ->where(["accessToken" => $token])
            ->one();
    if (!count($dbUser)) {
        return null;
    }
    return new static($dbUser);
}

/**
 * Finds user by username
 *
 * @param  string      $username
 * @return static|null
 */
public static function findByUsername($username) {
    $dbUser = DbUser::find()
            ->where([
                "username" => $username
            ])
            ->one();
    if (!count($dbUser)) {
        return null;
    }
    return new static($dbUser);
}

/**
 * @inheritdoc
 */
public function getId() {
    return $this->id;
}

/**
 * @inheritdoc
 */
public function getAuthKey() {
    return $this->authKey;
}

/**
 * @inheritdoc
 */
public function validateAuthKey($authKey) {
    return $this->authKey === $authKey;
}

/**
 * Validates password
 *
 * @param  string  $password password to validate
 * @return boolean if password provided is valid for current user
 */
public function validatePassword($password) {
    return $this->password === $password;
}

}
