如何使用Node.js将单个浮点变量从客户端流式传输到后端？

const net = require('net');

const client = new net.Socket();
const port = 3000;
const host = 'localhost';

client.connect(port, host, () => {
  console.log('Connected to server');

  const floatData = 3.14; // 浮点变量

  const buffer = Buffer.alloc(4); // 创建一个4字节的Buffer对象
  buffer.writeFloatLE(floatData); // 将浮点变量写入Buffer对象

  client.write(buffer); // 发送Buffer对象到后端
});

client.on('data', (data) => {
  console.log('Received data from server:', data.toString());
  client.destroy(); // 关闭与后端的连接
});

client.on('close', () => {
  console.log('Connection closed');
});

const net = require('net');

const server = net.createServer((socket) => {
  console.log('Client connected');

  socket.on('data', (data) => {
    const floatData = data.readFloatLE(); // 从接收到的Buffer对象中读取浮点变量
    console.log('Received data from client:', floatData);

    // 在这里可以对浮点变量进行处理或其他操作

    socket.write('Data received by server'); // 向客户端发送响应数据
  });

  socket.on('close', () => {
    console.log('Client disconnected');
  });
});

const port = 3000;
server.listen(port, () => {
  console.log('Server listening on port', port);
});
