Yii2 Basic模板-如何从mysql数据库登录

Question

我试图在Yii基本模板中实现用户模型和LoginForm模型，以验证用户登录。 我创建了一个数据库并连接到它。 数据库是表用户，并使用值填充了名为用户名，密码，authKey和acessToken的字段。 从ActiveRecord扩展了用户模型并实现了\\ yii \\ web \\ IdentityInterface，以使内置的Yii2函数发挥作用。 还写了这个方法：

public static function tableName() { return 'user'; }

每次我尝试登录时，都会从LoginForm模型中的validatepassword()抛出->用户名或密码错误。

这是我的代码：

LoginForm模型：

<?php

namespace app\models;

use Yii;
use yii\base\Model;

/**
 * LoginForm is the model behind the login form.
 */
class LoginForm extends Model
{
    public $username;
    public $password;
    public $rememberMe = true;

    private $_user = false;

    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            // username and password are both required
            [['username', 'password'], 'required'],
            // rememberMe must be a boolean value
            ['rememberMe', 'boolean'],
            // password is validated by validatePassword()
            ['password', 'validatePassword'],
        ];
    }

    /**
     * Validates the password.
     * This method serves as the inline validation for password.
     *
     * @param string $attribute the attribute currently being validated
     * @param array $params the additional name-value pairs given in the rule
     */
    public function validatePassword($attribute, $params)
    {
        if (!$this->hasErrors()) {
            $user = $this->getUser();

            if (!$user || !$user->validatePassword($this->password)) {
                $this->addError($attribute, 'Incorrect username or password.');
            }
        }
    }

    /**
     * Logs in a user using the provided username and password.
     * @return boolean whether the user is logged in successfully
     */
    public function login()
    {
        if ($this->validate()) {
            return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600*24*30 : 0);
        } else {
            return false;
        }
    }

    /**
     * Finds user by [[username]]
     *
     * @return User|null
     */
    public function getUser()
    {
        if ($this->_user === false) {
            $this->_user = User::findByUsername($this->username);
        }

        return $this->_user;
    }
}

…这是我的User.php模型：

<?php

namespace app\models;

use yii\db\ActiveRecord;

class User extends ActiveRecord implements \yii\web\IdentityInterface
{
    public $id;
    public $username;
    public $password;
    public $authKey;
    public $accessToken;

    public static function tableName() { return 'user'; }

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

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

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

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

    /**
     * @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;
    }

}

我不知道该怎么办，也许是在验证密码或找到用户名时出现问题，在Yii2调试中它表明已正确连接到mysql数据库。

不要弄乱siteController actionLogin()因为它等于高级模板，我认为保持这种方式是正确的。

简而言之，下面的函数会不断抛出“用户名或密码错误”：

public function validatePassword($attribute, $params)
{
    if (!$this->hasErrors()) {
        $user = $this->getUser();

        if (!$user || !$user->validatePassword($this->password)) {
            $this->addError($attribute, 'Incorrect username or password.');
        }
    }
}

我不想放弃，但是我正在考虑回到旧的Yii1.xx。 在那里，我可以轻松地查询数据库，并使良好的登录系统正常工作。

我花了将近72个小时来解决这个登录问题，但对于基本的Yii2模板，没有任何解决方案可以解决。

我不想使用软件包中默认提供的静态$users 。

Answer 1

1）停止创建重复的问题
2）删除下面的变量的公共声明。

class User extends ActiveRecord implements \yii\web\IdentityInterface
{
public $id;
public $username;
public $password;
public $authKey;
public $accessToken;

因此，$ user-> password将为空。 您实际上不是在声明值，而是使用魔术方法来获取值……使用它们时，它们将始终为空。
