"""配对码被占用时，在电脑上弹通知。
|
||
|
||
用户的要求：
|
||
"如果一个设备设置了配对码 789113，另一个设备也想设置 789113，
|
||
那不可以，你就弹通知，说该配对码已被使用，请换一个配对码"
|
||
|
||
现状：
|
||
中转服务器**已经**会拒绝（返回 "这个配对码已经被另一台设备用了，换一个"），
|
||
被控端也抛了这个错误 —— 但只是写进日志，用户根本看不到。
|
||
而且主循环会当成网络错误一直重试，刷屏。
|
||
|
||
要做的：
|
||
1. 中转返回里加 codeTaken 标记（让客户端能精确识别，不靠匹配中文）
|
||
2. 被控端加 RelayCodeTaken 异常
|
||
3. 加 on_alert 回调 —— 服务器把它接到界面通知上
|
||
4. 主循环遇到冲突时：**弹一次通知就停下来等**，不要反复重试刷屏
|
||
用户换了配对码之后自动继续。
