你优化后,更新一版代码

好的，这里提供一份优化后的代码，主要进行了如下改进：

1. 使用 Python 的定时器（`schedule` 模块）来实现定时获取直播间最新消息，避免过度消耗资源。

2. 在处理 WebSocket 消息时，先判断消息类型，避免出现解析错误。

3. 将获取最近消息和定时获取消息的代码块封装成函数，提高代码可读性和复用性。

4. 增加异常处理和错误提示，使代码更加健壮。

import time
import json
import requests
import websocket
import schedule

# 抖音直播间ID
room_id = '123456'

# 获取直播间消息接口
message_url = f'https://live.douyin.com/{room_id}/messages'

# WebSocket地址
ws_url = f'wss://douyusvc-hlh-web.douyucdn.cn/websocket/room/{room_id}'

# 连接websocket
ws = websocket.WebSocketApp(ws_url)

# 处理websocket消息
def on_message(ws, message):
    try:
        data = json.loads(message)
        if 'data' in data and 'messages' in data['data']:
            messages = data['data']['messages']
            for message in messages:
                content = message['content']
                uid = message['uid']
                print(f'用户{uid}: {content}')
    except Exception as e:
        print(f'处理WebSocket消息时出错: {e}')

# 获取最近消息
def get_recent_messages():
    try:
        response = requests.get(message_url)
        data = json.loads(response.text)
        messages = data['data']['messages']
        for message in messages:
            content = message['content']
            uid = message['uid']
            print(f'用户{uid}: {content}')
    except Exception as e:
        print(f'获取最近消息时出错: {e}')

# 定时获取直播间最新消息
def get_latest_messages():
    try:
        response = requests.get(message_url)
        data = json.loads(response.text)
        messages = data['data']['messages']
        for message in messages:
            content = message['content']
            uid = message['uid']
            print(f'用户{uid}: {content}')
    except Exception as e:
        print(f'定时获取消息时出错: {e}')

# 每隔1秒钟获取一次最新消息
schedule.every(1).seconds.do(get_latest_messages)

# 启动websocket
ws.on_message = on_message
ws.run_forever()

# 启动定时器
while True:
    schedule.run_pending()
    time.sleep(1)

需要注意的是，这段代码同样需要遵守抖音相关规定和法律法规，以免违反相关条款和法律法规。
