用户相关的key(表)：

用户注册：

 /**
     *  用户注册信息
     */
    public function userRegister()
    {
        $redis = RedisInstance::MasterInstance();
        $redis->select(10);
        $username = ‘tinywan‘.mt_rand(0000,8888);
        $password = ‘123456‘;
        if($redis->get(‘user:username:‘.$username.‘:userid‘)){
            exit(‘该用户名没有被使用‘);
        }
        //获取全局userId
        $userId = $redis->incr(‘global:userid‘);
        $redis->set(‘user:userId:‘.$userId.‘:username‘,$username);
        $redis->set(‘user:userId:‘.$userId.‘:password‘,$password);
        $redis->set(‘user:username:‘.$username.‘:userid‘,$userId);
    }

用于登录:

 /**
     *      用于登录信息
     */
    public function userLogin()
    {
        $redis = RedisInstance::MasterInstance();
        $redis->select(10);
        $username = ‘tinywan8165‘;
        $password = ‘123456‘;
        $uid = $redis->get(‘user:username:‘.$username.‘:userid‘);
        if($uid == false){
            exit(‘该用户名不存在‘);
        }
        $oldpwd = $redis->get(‘user:userId:‘.$uid.‘:password‘);
        if($password != $oldpwd){
            exit(‘密码错误‘);
        }
        echo ‘登录成功，跳转‘;
        homePrint($uid);
    }
