问题
I have a table in my DB called 'member' where I intend to store username, password and all other related info of a user and I want to use those username/password for login instead yii2's default User.php model. I have been trying for almost a day and modified the Member.php model but can't make it work. Every time I use my custom username/password from db, it says username or password is incorrect. Can anyone please help me out? Thanks in advance. :)
FYI, I have no such field in member table such as authKey or accessToken. I have tried all the related stackoverflow posts but in vein.
Member.php Model
namespace app\models;
use Yii;
use yii\web\IdentityInterface;
class Member extends \yii\db\ActiveRecord implements IdentityInterface
{
public static function tableName()
{
return 'member';
}
public function rules()
{
return [
[['username', 'password', 'first_name', 'last_name', 'role'], 'required'],
[['created_by_date', 'last_modified_by_date'], 'safe'],
[['username', 'password', 'role', 'created_by_id', 'last_modified_by_id'], 'string', 'max' => 50],
[['first_name', 'last_name', 'middle_name', 'phone', 'mobile'], 'string', 'max' => 100],
[['email'], 'string', 'max' => 250],
[['address_line1', 'address_line2', 'address_line3'], 'string', 'max' => 512]
];
}
public function attributeLabels()
{
return [
'id' => 'ID',
'username' => 'Username',
'password' => 'Password',
'first_name' => 'First Name',
'last_name' => 'Last Name',
'middle_name' => 'Middle Name',
'email' => 'Email',
'phone' => 'Phone',
'mobile' => 'Mobile',
'address_line1' => 'Address Line1',
'address_line2' => 'Address Line2',
'address_line3' => 'Address Line3',
'role' => 'Role',
'created_by_id' => 'Created By ID',
'created_by_date' => 'Created By Date',
'last_modified_by_id' => 'Last Modified By ID',
'last_modified_by_date' => 'Last Modified By Date',
];
}
public static function find()
{
return new MemberQuery(get_called_class());
}
public static function findIdentity($id)
{
$dbUser = self::find()
->where([
"id" => $id
])
->one();
if (!count($dbUser)) {
return null;
}
return new static($dbUser);
}
public static function findIdentityByAccessToken($token, $userType = null)
{
$dbUser = self::find()
->where(["accessToken" => $token])
->one();
if (!count($dbUser)) {
return null;
}
return new static($dbUser);
}
public static function findByUsername($username)
{
$dbUser = self::find()
->where(["username" => $username])
->one();
if (!count($dbUser)) {
return null;
}
return $dbUser;
}
public function getId()
{
return $this->id;
}
public function getAuthKey()
{
return $this->authKey;
}
public function validateAuthKey($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;
}
}
config/web.php
'user' => [
'identityClass' => 'app\models\Member',
'enableAutoLogin' => true,
],
I didnt change the User.php model. Here it is:
namespace app\models;
class User extends \yii\base\Object implements \yii\web\IdentityInterface
{
private static $users = [
'100' => [
'id' => '100',
'username' => 'admin',
'password' => 'admin',
'authKey' => 'test100key',
'accessToken' => '100-token',
],
'101' => [
'id' => '101',
'username' => 'demo',
'password' => 'demo',
'authKey' => 'test101key',
'accessToken' => '101-token',
],
];
/**
* @inheritdoc
*/
public static function findIdentity($id)
{
return isset(self::$users[$id]) ? new static(self::$users[$id]) : null;
}
/**
* @inheritdoc
*/
public static function findIdentityByAccessToken($token, $type = null)
{
foreach (self::$users as $user) {
if ($user['accessToken'] === $token) {
return new static($user);
}
}
return null;
}
/**
* Finds user by username
*
* @param string $username
* @return static|null
*/
public static function findByUsername($username)
{
foreach (self::$users as $user) {
if (strcasecmp($user['username'], $username) === 0) {
return new static($user);
}
}
return null;
}
/**
* @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;
}
}

You should make sure you change the getUser() method on models/LoginForm.php to use your Member model class, otherwise it will keep validating against the default User model.
public function getUser() {
if ($this->_user === false) {
$this->_user = Member::findByUsername($this->username);
}
return $this->_user;
}
Also, here is an example of my own User model class
namespace app\models;
use Yii;
class User extends \yii\db\ActiveRecord implements \yii\web\IdentityInterface {
const SCENARIO_LOGIN = 'login';
const SCENARIO_CREATE = 'create';
public static function tableName() {
return 'user';
}
public function scenarios() {
$scenarios = parent::scenarios();
$scenarios[self::SCENARIO_LOGIN] = ['username', 'password'];
$scenarios[self::SCENARIO_CREATE] = ['username', 'password', 'authKey'];
return $scenarios;
}
public function rules() {
return [
[['username', 'email'], 'string', 'max' => 45],
[['email'], 'email'],
[['password'], 'string', 'max' => 60],
[['authKey'], 'string', 'max' => 32],
[['username', 'password', 'email'], 'required', 'on' => self::SCENARIO_CREATE],
[['authKey'], 'default', 'on' => self::SCENARIO_CREATE, 'value' => Yii::$app->getSecurity()->generateRandomString()],
[['password'], 'filter', 'on' => self::SCENARIO_CREATE, 'filter' => function($value) {
return Yii::$app->getSecurity()->generatePasswordHash($value);
}],
[['username', 'password'], 'required', 'on' => self::SCENARIO_LOGIN],
[['username'], 'unique'],
[['email'], 'unique'],
[['authKey'], 'unique'],
];
}
public function attributeLabels() {
return [
'id' => 'Id',
'username' => 'Username',
'password' => 'Password',
'email' => 'Email',
'authKey' => 'authKey',
];
}
public static function findIdentity($id) {
return self::findOne($id);
}
public static function findIdentityByAccessToken($token, $type = null) {
throw new NotSupportedException('"findIdentityByAccessToken" is not implemented.');
}
public static function findByUsername($username) {
return static::findOne(['username' => $username]);
}
public function getId() {
return $this->getPrimaryKey();
}
public function getAuthKey() {
return $this->authKey;
}
public function validateAuthKey($authKey) {
return $this->authKey === $authKey;
}
public function validatePassword($password) {
return Yii::$app->getSecurity()->validatePassword($password, $this->password);
}
}
Make sure the methods from IdentityInterface you implement but don't want to use throw an exception, just like i do on the findIdentityByAccessToken method.
回答2:
You should extend User class with your Member class and set in main config:
[...]
'modules' => [
'user' => [
'class' => 'member class
'modelMap' => [
'User' => 'app\models\member',
