Yii2框架无法使用自定义数据库登录

[英]Yii2 framework cannot login using a custom database

新手和学习yii2。 我有一个自定义的用户数据库,希望用作我的登录凭证,幸运的是,我能够查询它,但是在我的公共静态函数validatePassword($ password)上,当不在对象上下文中时,我得到了using $ this。

这是我的代码

public static function findByUsername($username)
{
   $user = self::find()->where(['USR_USERNAME' => $username, 'USR_STATUS' => '1'])->one();
   return new static($user);
}

public function getId()
{
    return $this->id;
}

/**
 * {@inheritdoc}
 */


public static function validatePassword($password)
{
    return $this->password === $password;
}

这是我的错误的屏幕截图。 在此处输入图片说明

所有脚本都是使用gii模块生成的,所以我不知道为什么会产生此错误,而且在观看教程时,我会复制其代码,但最终无法正常工作。 请帮忙,谢谢。

根据要求,这里是DbUser.php代码

<?php

namespace app\models;

use Yii;

/**
 * This is the model class for table "{{%RBAC_USERS}}".
 *
 * @property string $USR_UID
 * @property string $USR_USERNAME

 * @property string $USR_EMAIL

 * @property string $USR_CREATE_DATE
 * @property string $USR_UPDATE_DATE
 * @property int $USR_STATUS
 * @property string $USR_AUTH_TYPE

class DbUsers extends \yii\db\ActiveRecord implements \yii\web\IdentityInterface

{

    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return '{{%RBAC_USERS}}';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['USR_UID', 'USR_DUE_DATE'], 'required'],
            [['USR_DUE_DATE', 'USR_CREATE_DATE', 'USR_UPDATE_DATE'], 'safe'],
            [['USR_STATUS'], 'integer'],
            [['USR_UID', 'USR_AUTH_TYPE', 'UID_AUTH_SOURCE'], 'string', 'max' => 32],
            [['USR_USERNAME', 'USR_EMAIL'], 'string', 'max' => 100],
            [['USR_PASSWORD'], 'string', 'max' => 128],

            [['USR_AUTH_USER_DN', 'USR_AUTH_SUPERVISOR_DN'], 'string', 'max' => 255],
            [['USR_UID'], 'unique'],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'USR_UID' => Yii::t('app', 'Uid'),
            'USR_USERNAME' => Yii::t('app', 'Username'),
            'USR_PASSWORD' => Yii::t('app', 'Password'),
        ];
    }


    /**
     * {@inheritdoc}
     */
    public static function findIdentity($id)
    {
        throw new NotSupportedException();
    }

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

        throw new NotSupportedException();
    }

    /**
     * Finds user by username
     *
     * @param string $username
     * @return static|null
     */
    public function getAuthKey()
    {
        throw new NotSupportedException();
    }

    /**

     */
    public function validateAuthKey($authKey)
    {
        throw new NotSupportedException();
    }

    public static function findByUsername($username, $password)
    {
        $user = self::find()->where(['USR_USERNAME' => $username, 'USR_STATUS' => '1'])->one();

        return $user;


    }

    public function getId()
    {
        return $this->getPrimaryKey();
    }

    /**
     * {@inheritdoc}
     */


    public static function validatePassword($password)
    {
        return $this->password === $password;
    }


}

这是我的LoginForm.php

<?php

namespace app\models;

use Yii;
use yii\base\Model;


/**
 * LoginForm is the model behind the login form.
 *
 * @property User|null $user This property is read-only.
 *
 */
class LoginForm extends Model
{
    public $username;
    public $password;
    public $rememberMe = false;

    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 bool 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);

        }

        return false;
    }

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

        return $this->_user;
    }
}

在静态函数中,不能使用$ this。 使validatePassword()函数为非静态。

您不能将$this与静态函数一起使用,更改为

public function validatePassword($password)
{
   return $this->password === $password;
}

请更新您的问题,添加一个DbUsers模型代码。 在哪里执行方法validatePassword() 当然,您不能在静态方法中使用$ this,而使该方法不是静态的

我回答我自己的问题。 我在查找中添加了以下代码

  public static function findByUsername($username, $password)
    {
        $user = self::find()->where(['USR_USERNAME' => $username, 'USR_STATUS' => '1'])->one();

        if (hash('sha256', $password) == $user->USR_PASSWORD)
        {
            return new static($user);
        }


    }

现在,这将验证是否以sha256加密方式将密码与数据库匹配,然后在我的validatePassword方法上将其修改为simple,始终返回true,因为在LoginForm上,他们总是先搜索用户名,然后检查密码验证,因此如果用户名/密码错误,它将立即验证该用户不存在

 public static function validatePassword($password)
    {
        return true;
    }

我发现yii2很难,因为缺少文档非常难。
