代码没有，运行环境保密，玩蛋去吧…
你好，我需要一个python程序，它接收一组udp消息，解析udp里的特定数据，然后把解析后的重新组织的数据通过websocket协议发给另一个程序。解析函数占位即可，我后续再编写。
websocket是另一个服务端，我这里需要的程序是一个websocket客户端
明白了，你需要一个程序作为 UDP 服务器 接收数据，解析后作为 WebSocket 客户端 连接到另一个 WebSocket 服务端并发送数据。以下是修改后的代码：
- import asyncio
- import websockets
- import socket
- import json
- from typing import Dict, Any
- class UDPToWebSocketClient:
- def __init__(self, udp_host: str = '0.0.0.0', udp_port: int = 9999,
- ws_uri: str = 'ws://localhost:8765'):
- self.udp_host = udp_host
- self.udp_port = udp_port
- self.ws_uri = ws_uri
- self.udp_socket = None
- self.websocket = None
- self.running = False
- async def parse_udp_message(self, data: bytes) -> Dict[str, Any]:
- """
- 解析UDP消息的占位函数
- 这里应该实现具体的解析逻辑，返回解析后的字典
- """
- # TODO: 实现具体的解析逻辑
- parsed_data = {
- 'raw_data': data.hex(),
- 'length': len(data),
- # 可以添加更多解析后的字段
- }
- return parsed_data
- async def handle_udp_messages(self):
- """处理UDP消息接收"""
- loop = asyncio.get_running_loop()
-
- # 创建UDP socket
- self.udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
- self.udp_socket.bind((self.udp_host, self.udp_port))
- self.udp_socket.setblocking(False)
-
- print(f"Listening for UDP messages on {self.udp_host}:{self.udp_port}")
-
- while self.running:
- try:
- data, addr = await loop.sock_recvfrom(self.udp_socket, 65536)
- print(f"Received UDP message from {addr}: {data}")
-
- # 解析UDP消息
- parsed_data = await self.parse_udp_message(data)
-
- # 发送给WebSocket服务器
- if self.websocket and self.websocket.open:
- await self.websocket.send(json.dumps(parsed_data))
- else:
- print("WebSocket connection not ready, message dropped")
-
- except Exception as e:
- print(f"Error handling UDP message: {e}")
- await asyncio.sleep(0.1) # 避免CPU占用过高
- async def connect_websocket(self):
- """连接到WebSocket服务器"""
- while self.running:
- try:
- print(f"Connecting to WebSocket server at {self.ws_uri}...")
- async with websockets.connect(self.ws_uri) as ws:
- self.websocket = ws
- print("Connected to WebSocket server")
-
- # 保持连接，直到断开或程序停止
- await self.websocket.wait_closed()
- print("WebSocket connection closed, reconnecting...")
-
- except Exception as e:
- print(f"WebSocket connection error: {e}")
- await asyncio.sleep(5) # 等待5秒后重连
- async def run(self):
- """启动桥接服务"""
- self.running = True
-
- # 启动WebSocket客户端（自动重连）
- ws_task = asyncio.create_task(self.connect_websocket())
-
- # 启动UDP服务器
- udp_task = asyncio.create_task(self.handle_udp_messages())
-
- # 等待任务完成（理论上不会结束，除非手动停止）
- await asyncio.gather(ws_task, udp_task)
- def stop(self):
- """停止服务"""
- self.running = False
- if self.udp_socket:
- self.udp_socket.close()
- if self.websocket:
- asyncio.create_task(self.websocket.close())
- async def main():
- bridge = UDPToWebSocketClient(
- udp_host='0.0.0.0', # 监听所有网络接口
- udp_port=9999, # UDP监听端口
- ws_uri='ws://localhost:8765' # WebSocket服务器地址
- )
-
- try:
- await bridge.run()
- except KeyboardInterrupt:
- print("Shutting down...")
- bridge.stop()
- if __name__ == '__main__':
- asyncio.run(main())
