yii 后台模版 adminLTE 以及后台用户分离

yii 安装完毕，介绍一款帅气的后台模版 adminLTE
git地址： https://github.com/dmstr/yii2-adminlte-asset

安装参考 ReadMe

php composer.phar require dmstr/yii2-adminlte-asset "2.*"

安装完成后修改配置文件： backend/config/main.php 添加代码：

'view' => [    'theme' => [        'pathMap' => [            '@app/views' => '@vendor/dmstr/yii2-adminlte-asset/example-views/yiisoft/yii2-app'        ],    ],],

但是这样不利于我们之后对它的修改，所以复制yii2-adminlte的 layout 和 site到 backend/views 下，删除上面的配置也可以达到效果。

分离后台用户

首先创建后台用户表：
执行命令：

yii migrate/create admin_user

然后修改生成的 迁移文件：

public function up()    {        $this->createTable('admin_user', [            'id' => $this->primaryKey(),            'username' => $this->string()->notNull()->unique(),            'auth_key' => $this->string(32)->notNull(),            'password_hash' => $this->string()->notNull(),            'password_reset_token' => $this->string()->unique(),            'email' => $this->string()->notNull()->unique(),            'status' => $this->smallInteger()->notNull()->defaultValue(10),            'created_at' => $this->integer()->notNull(),            'updated_at' => $this->integer()->notNull(),        ]);    }    public function down()    {        $this->dropTable('admin_user');    }

运行命令：

yii migrate

生成 admin_user 表
接下来修改配置文件： backend/config/main.php，修改对user的配置为下面这样：

'user' => [            'identityClass' => 'backend\models\AdminUser',            'enableAutoLogin' => false,            'identityCookie' => ['name' => '_identity-backend', 'httpOnly' => true],        ],

在 backend/models/下创建 AdminUser.php 内容如下：

<?phpnamespace backend\models;use Yii;use yii\base\NotSupportedException;use yii\behaviors\TimestampBehavior;use yii\db\ActiveRecord;use yii\web\IdentityInterface;/** * User model * * @property integer $id * @property string $username * @property string $password_hash * @property string $password_reset_token * @property string $email * @property string $auth_key * @property integer $status * @property integer $created_at * @property integer $updated_at * @property string $password write-only password */class AdminUser extends ActiveRecord implements IdentityInterface{    const STATUS_DELETED = 0;    const STATUS_ACTIVE = 10;    /**     * @inheritdoc     */    public static function tableName()    {        return 'admin_user';    }    /**     * @inheritdoc     */    public function behaviors()    {        return [            TimestampBehavior::className(),        ];    }    /**     * @inheritdoc     */    public function rules()    {        return [            [['username', 'auth_key', 'password_hash', 'email', 'created_at', 'updated_at'], 'required'],            [['status', 'created_at', 'updated_at'], 'integer'],            [['username', 'auth_key'], 'string', 'max' => 32],            [['password_hash', 'password_reset_token', 'email'], 'string', 'max' => 255],            [['username','email'], 'unique'],        ];    }    /**     * @inheritdoc     */    public function attributeLabels()    {        return [            'id' => 'ID',            'username' => '用户名',            'auth_key' => 'Auth Key',            'password_hash' => 'Password Hash',            'password_reset_token' => 'Password Reset Token',            'email' => '邮箱',            'status' => '状态',            'created_at' => '创建时间',            'updated_at' => '更新时间',        ];    }    /**     * @inheritdoc     */    public static function findIdentity($id)    {        return static::findOne(['id' => $id, 'status' => self::STATUS_ACTIVE]);    }    /**     * @inheritdoc     */    public static function findIdentityByAccessToken($token, $type = null)    {        throw new NotSupportedException('"findIdentityByAccessToken" is not implemented.');    }    /**     * Finds user by username     *     * @param string $username     * @return static|null     */    public static function findByUsername($username)    {        return static::findOne(['username' => $username, 'status' => self::STATUS_ACTIVE]);    }    public static function findByEmail($email)    {        return static::findOne(['email' => $email]);    }    /**     * Finds user by password reset token     *     * @param string $token password reset token     * @return static|null     */    public static function findByPasswordResetToken($token)    {        if (!static::isPasswordResetTokenValid($token)) {            return null;        }        return static::findOne([            'password_reset_token' => $token,            'status' => self::STATUS_ACTIVE,        ]);    }    /**     * Finds out if password reset token is valid     *     * @param string $token password reset token     * @return boolean     */    public static function isPasswordResetTokenValid($token)    {        if (empty($token)) {            return false;        }        $timestamp = (int) substr($token, strrpos($token, '_') + 1);        $expire = Yii::$app->params['user.passwordResetTokenExpire'];        return $timestamp + $expire >= time();    }    /**     * @inheritdoc     */    public function getId()    {        return $this->getPrimaryKey();    }    /**     * @inheritdoc     */    public function getAuthKey()    {        return $this->auth_key;    }    /**     * @inheritdoc     */    public function validateAuthKey($authKey)    {        return $this->getAuthKey() === $authKey;    }    /**     * Validates password     *     * @param string $password password to validate     * @return boolean if password provided is valid for current user     */    public function validatePassword($password)    {        return Yii::$app->security->validatePassword($password, $this->password_hash);    }    /**     * Generates password hash from password and sets it to the model     *     * @param string $password     */    public function setPassword($password)    {        $this->password_hash = Yii::$app->security->generatePasswordHash($password);    }    /**     * Generates "remember me" authentication key     */    public function generateAuthKey()    {        $this->auth_key = Yii::$app->security->generateRandomString();    }    /**     * Generates new password reset token     */    public function generatePasswordResetToken()    {        $this->password_reset_token = Yii::$app->security->generateRandomString() . '_' . time();    }    /**     * Removes password reset token     */    public function removePasswordResetToken()    {        $this->password_reset_token = null;    }}

修改 backend/controllers/SiteController.php 主要是 use 部分

use Yii;use yii\web\Controller;use yii\filters\VerbFilter;use yii\filters\AccessControl;use backend\models\LoginForm;

主要是 使用后台自己的LoginForm
修改（没有则创建） backend/models/LoginForm.php

<?phpnamespace backend\models;use Yii;use yii\base\Model;/** * Login form */class LoginForm extends Model{    public $username;    public $password;    public $rememberMe = true;    private $_user;    /**     * @inheritdoc     */    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(), $this->rememberMe ? 3600 * 24 * 30 : 0);        } else {            return false;        }    }    /**     * Finds user by [[username]]     *     * @return User|null     */    protected function getUser()    {        if ($this->_user === null) {            $this->_user = AdminUser::findByUsername($this->username);        }        return $this->_user;    }}

主要注意代码：

$this->_user = AdminUser::findByUsername($this->username);

接下来就可以在 admin_user 表中手动创建一个账户，用于登录了（后台关闭注册功能，之后添加管理员也通过后台实现。）
添加 数据中的 password_hash 可以通过user表复制过来一个
到此，以后后台用户都是查询 admin_user表了。
接下来你可以后台创建针对admin_user 的CRUD模块。
