);

// 根据openid判断用户是否已经注册过
$user = PHPCMSUser::select()->where('openid', $data['openid'])->first();
if($user){
    // 用户已注册，直接登录
    PHPCMSUser::login($user); // 登录
}else{
    // 用户未注册，进行注册流程
    PHPCMSUser::register($data); // 注册
    PHPCMSUser::login($user); // 登录
}

In the above code example, we log in or register the user by obtaining the user's openid, nickname and avatar information carried by the WeChat callback.
