Yii Framework2.0开发教程（10）配合mysql数据库实现用户登录

1、首先在mysql创建一个存用户的表格

create table test_user
(
user_id bigint(20) unsigned not null auto_increment comment 'ID',
user_email varchar(100) not null comment '电子邮件',
user_password varchar(100) not null comment '密码',
user_access_token varchar(200) comment 'access_token',
user_auth_key varchar(200) comment 'auth_key',
user_create_time datetime comment '创建时间',
primary key(user_id)
);

2、在表中插入一条登陆的账号

3、新建模型models/MysqlUser.php

<?php

namespace app\models;

use yii\db\ActiveRecord;
use yii\web\IdentityInterface;

class MysqlUser extends ActiveRecord implements IdentityInterface
{
	public static function tableName()
	{
		//对应的表名
		return 'test_user';
	}

	public static function findIdentity($id)
	{
		//自动登陆时会调用
		$temp = parent::find()->where(['user_id'=>$id])->one();
		return isset($temp)?new static($temp):null;
	}

	public static function findIdentityByAccessToken($token, $type = null)
	{
		return static::findOne(['user_access_token' => $token]);
	}

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

	public function getAuthKey()
	{
		return $this->user_auth_key;
	}

	public function validateAuthKey($authKey)
	{
		return $this->user_auth_key === $authKey;
	}

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

4、新建模型models/MloginForm.php

<?php

namespace app\models;

use Yii;
use yii\base\Model;

//加上这一句，引用
use app\models\MysqlUser;

class MloginForm extends Model
{
	public $email;
	public $password;

	private $_user = false;

	public function rules()
	{
		return [
			['email','email','message'=>'必须是邮件格式'],
			[['email','password'],'required','message'=>'必填'],
			['password','validatePassword','message'=>'账号或密码不正确'],
		];
	}

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

	//判断账号密码是否正确
	public function validatePassword($attribute, $params)
	{
		if (!$this->hasErrors())
		{
			$user = $this->getUser();

			if (!$user)
			{
      	$this->addError($attribute, '账号或密码不正确');
      }

		}
	}

	//根据邮箱和密码查询数据库
	public function getUser()
	{
		if ($this->_user === false)
		{
			$this->_user = MysqlUser::find()->where(['user_email'=>$this->email,'user_password'=>$this->password])->one();
		}
		return $this->_user;
	}

}

?>

5、新建视图views/account/login.php

<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
?>
<?php
echo '<h1>'.$status.'</h1>';
?>
<?php $form = ActiveForm::begin(); ?>
<?php echo $form->field($model, 'email'); ?>
<?php echo $form->field($model, 'password'); ?>
<?php echo Html::submitButton('登陆'); ?>
<?php ActiveForm::end(); ?>

6、新建控制器controllers/AccountController.php

<?php
namespace app\controllers;

use Yii;
use yii\filters\AccessControl;
use yii\web\Controller;
use yii\filters\VerbFilter;

//引用
use app\models\MloginForm;

class AccountController extends Controller
{
	function actionLogin()
	{
		$model = new MloginForm();
		if($model->load(Yii::$app->request->post()))
		{
			if($model->login())
				//登陆成功
				return $this->renderPartial('login',['model'=>$model,'status'=>'成功']);
			else
				//登陆失败
				return $this->renderPartial('login',['model'=>$model,'status'=>'失败']);
		}
		else
		{
			return $this->renderPartial('login',['model'=>$model,'status'=>'']);
		}
	}
}

另外，自动登陆配置的地方是config/web.php

效果如下所示

点击登陆按钮后

若账号密码不正确

自动登陆还有点问题，等之后解决。
