之前写了一个帖子ha播放小爱音箱的会员歌曲 - 『HomeAssistant』综合讨论区 - 『瀚思彼岸』» 智能家居技术论坛 - Powered by Discuz! (hassbian.com)，实现了小爱音箱如果遇到会员歌曲，会用云音乐替换，然后再在其他蓝牙设备或接入ha的设备上播放；
这次受小爱音箱播放NAS音乐 - 『HomeAssistant』综合讨论区 - 『瀚思彼岸』» 智能家居技术论坛 - Powered by Discuz! (hassbian.com)大佬启发，小爱可以播放URL的音乐了，大佬没有给出具体实现教程，经过一番努力，终于实现了适合我的小爱音箱替换会员歌曲。
把我的实现方法分享给大家：
1.把nas音乐通过SMB挂载到alist里边；如图1
2.在nodered里边用Python脚本抓取音乐名字，并保存在本地的一个txt中。
我是把nr的root文件夹映射了出来，放在nas-docker-nr2-root文件夹中，如图2
Python代码如下：
import requests
import json
# 请求URL和负载数据
url = "http://192.168.1.222:5244/api/fs/list"
payload = {
"path": "/nas music/无损音乐一千多首",
"password": "",
"page": 1,
"per_page": 0,
"refresh": False
}
# 请求头信息，包括JWT令牌
headers = {
"Authorization": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6InNpbGFzMzA4MiIsImV4cCI6MTY5NTQ2NTkxNSwibmJmIjoxNjk1MjkzMTE1LCJpYXQiOjE2OTUyOTMxMTV9.MA6rTdWcLXZyTE5WQ8YVGd9rCUcro18DVBisfXQT74U"
}
# 发送POST请求，包括请求头
response = requests.post(url, json=payload, headers=headers)
# 检查响应状态码
if response.status_code == 200:
try:
# 解析响应数据
data = response.json()
# 调试输出响应数据
print("响应数据:")
print(json.dumps(data, indent=4))
# 获取歌曲名字
song_names = [item["name"] for item in data["data"]["content"]]
# 保存歌曲名字到本地文件
with open("/root/song_names2.txt", "w", encoding="utf-8") as file:
for song_name in song_names:
file.write(song_name + "\n")
print("歌曲名字已保存到 song_names.txt 文件中。")
except json.JSONDecodeError:
print("响应数据格式不正确，无法解析 JSON 数据。")
else:
print(f"请求失败，状态码: {response.status_code}")
3.在nr中实现查询音乐，并播放功能；
流程如下：

其中包含一个查找歌曲的Python代码，如图3
这样就实现了，当小爱有会员歌曲时，会从本地查找，直接通过小爱音箱播放出来。当然这个适合我，并不能完全照抄，有些地方需要结合自己的配置修改。
