## 用于控制 MPD 服务器的 Node-RED 节点
[English README](README.md)
本项目用于控制 Music Player Daemon (MPD) 服务器，并接收来自服务器的状态更新（如当前播放的歌曲）。
我一直在使用 [node-red-contrib-mpd](https://flows.nodered.org/node/node-red-contrib-mpd)，该模块基于 mpd 模块，已有多年未更新。在使用过程中，连接经常中断。因此，我基于 mpd2 模块开发了本项目，以提高与音乐播放守护进程连接的稳定性。
---
### v1.1.0 更新：
- 兼容一些mpc命令
#### 您可以使用以下命令：
* msg.payload = "play" - 开始播放
* msg.payload = "stop" - 停止播放
* msg.payload = "toggle" - 播放/暂停切换（等同于 pause）
* msg.payload = "pause" - 暂停播放
* msg.payload = "next" - 播放下一首
* msg.payload = "prev" - 播放上一首
* msg.payload = "add example.mp3" - 添加本地音乐文件
* msg.payload = "add https://www.example.com/music.mp3" - 添加远程音乐 URL
* msg.payload = "setvol 80" - 设置音量（旧格式）
* msg.payload = "volume 80" - 设置音量80%
* msg.payload = "volume +5" - 音量增加5%
* msg.payload = "volume -10" - 音量减少10%
* msg.payload = "clear" - 清空播放列表
* msg.payload = "playlistinfo" - 查看播放列表信息
* msg.payload = "status" - 查看当前状态
* msg.payload = "currentsong" - 查看当前歌曲（等同于 current）
* msg.payload = "current" - 查看当前歌曲
* msg.payload = "ls" - 列出音乐库（等同于 lsinfo）
* msg.payload = "listall" - 递归列出所有歌曲
* msg.payload = "save myplaylist" - 保存播放列表
* msg.payload = "load myplaylist" - 加载播放列表
* msg.payload = "random on" - 开启随机播放
* msg.payload = "random off" - 关闭随机播放
* msg.payload = "repeat on" - 开启全部循环
* msg.payload = "repeat off" - 关闭循环
* msg.payload = "repeat 1" - 开启单曲循环
* msg.payload = "update" - 更新数据库
* ...
