代码如何与其他设备进行通信?

代码如何与其他设备进行通信取决于代码的语言和平台。以下是一些通用的代码示例：

C++

#include 
#include 
#include 

int main() {
  // Create a socket
  int sock = socket(AF_INET, SOCK_STREAM, 0);

  // Connect to a remote host
  struct sockaddr_in server_addr;
  server_addr.sin_family = AF_INET;
  server_addr.sin_port = htons(8080);
  server_addr.sin_addr.s_addr = inet_addr("127.0.0.1");

  // Send data
  char message[] = "Hello from C++!";
  int len = send(sock, message, sizeof(message), 0);

  // Close the socket
  close(sock);

  return 0;
}

Java

import java.net.*;

public class Communication {

    public static void main(String[] args) throws IOException {
        // Create a socket
        Socket socket = new Socket("127.0.0.1", 8080);

        // Send data
        socket.getOutputStream().write("Hello from Java!".getBytes());

        // Close the socket
        socket.close();
    }
}

Python

import socket

# Create a socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Connect to a remote host
server_address = ("127.0.0.1", 8080)
sock.connect(server_address)

# Send data
sock.sendall("Hello from Python!".encode())

# Close the socket
sock.close()

JavaScript

const socket = new WebSocket("ws://127.0.0.1:8080");

// Send data
socket.send("Hello from JavaScript!");

// Listen for incoming data
socket.onmessage = function (event) {
  console.log(event.data);
};

请注意，这些只是通用的代码示例，您可能需要根据您的编程语言和平台进行调整。
