WebSocket在即時地理位置共享應用程式中的應用案例和技巧

// 连接WebSocket服务器
var ws = new WebSocket('ws://example.com/');

// 监听连接事件
ws.onopen = function() {
  // 发送用户地理位置信息
  navigator.geolocation.watchPosition(function(position) {
    var location = {
      latitude: position.coords.latitude,
      longitude: position.coords.longitude
    };
    ws.send(JSON.stringify(location));
  });
};

// 监听接收消息事件
ws.onmessage = function(event) {
  var message = JSON.parse(event.data);
  // 处理接收到的位置信息
  console.log('Received location:', message);
};

// 监听断开连接事件
ws.onclose = function() {
  console.log('WebSocket connection closed');
};

# 导入WebSocket模块
import asyncio
import websockets

# 处理WebSocket连接
async def handle_connection(websocket, path):
  while True:
    try:
      # 接收位置信息
      location = await websocket.recv()
      # 处理位置信息
      print('Received location:', location)
      # 广播位置信息给其他连接的用户
      await broadcast_location(location)
    except websockets.ConnectionClosed:
      break

# 广播位置信息给其他连接的用户
async def broadcast_location(location):
  for websocket in connected_websockets:
    await websocket.send(location)

# 启动WebSocket服务器
start_server = websockets.serve(handle_connection, '0.0.0.0', 8000)

# 事件循环
asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()
