YII2框架中自定义用户认证模型，完成登陆和注册操作示例_php实例_

 CREATE TABLE `tb_user` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT '用户ID', `name` varchar(32) DEFAULT '' COMMENT '用户名', `pwd` varchar(64) DEFAULT '' COMMENT '密码', `head_img` varchar(256) DEFAULT '' COMMENT '图像', `sex` tinyint(1) DEFAULT '0' COMMENT '性别(0:男,1:女)', `age` tinyint(3) DEFAULT '0' COMMENT '年龄', `auth_key` varchar(32) DEFAULT '' COMMENT '认证密钥', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='用户表'; 

 $token]); } //通过用户名，返回用户实例 public static function findByUsername($name) { return static::findOne(['name' => $name]); } //获取用户ID public function getId() { return $this->id; } //获取用户认证密钥 public function getAuthKey() { return $this->auth_key; } //生成cookie中的authkey public function generateAuthKey() { $this->auth_key = Yii::$app->security->generateRandomString(32); $this->save(false); } //验证用户认证密钥 public function validateAuthKey($authKey) { return $this->getAuthKey() === $authKey; } //验证密码是否正确，当然我们也可以自已定义加密解密方式 public function validatePassword($password) { return Yii::$app->security->validatePassword($password, $this->pwd); } }
