网络编程毕设实例可以从多个方面进行选择，包括TCP服务器、UDP聊天室、Web服务器、进程间通信等。以下是一些具体的实例和代码示例，帮助你完成毕设。
1. 简单的TCP服务器
Python示例
```python
import socketserver
class MyTCPHandler(socketserver.BaseRequestHandler):
"""
The request handler class for our server.
It is instantiated once per connection to the server, and must
override the handle() method to implement communication to the
client.
"""
def handle(self):
self.request is the TCP socket connected to the client
self.data = self.request.recv(1024).strip()
print(f"{self.client_address} wrote:".format(self.client_address))
print(self.data)
just send back the same data, but upper-cased
self.request.sendall(self.data.upper())
if __name__ == "__main__":
HOST, PORT = "localhost", 9999
Create the server, binding to localhost on port 9999
server = socketserver.TCPServer((HOST, PORT), MyTCPHandler)
Activate the server; this will keep it running until you
interrupt the program with Ctrl-C
server.serve_forever()
```
2. UDP聊天室
Python示例
```python
import socket
UDP_IP = "127.0.0.1"
UDP_PORT = 5555
sock = socket.socket(socket.AF_INET, Internet
socket.SOCK_DGRAM) UDP
sock.bind((UDP_IP, UDP_PORT))
while True:
data, addr = sock.recvfrom(1024) buffer size is 1024 bytes
print(f"收到来自{addr}的消息: {data}")
sock.sendto(data, addr)
```
3. 基于Twisted的Echo服务器
Python示例
```python
from twisted.internet import protocol, reactor
class Echo(protocol.Protocol):
def dataReceived(self, data):
self.transport.write(data)
class EchoFactory(protocol.Factory):
def buildProtocol(self, addr):
return Echo()
reactor.listenTCP(8000, EchoFactory())
reactor.run()
```
4. 基于Java的TCP服务器
Java示例
```java
import java.io.*;
import java.net.*;
public class TCPServer {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = new ServerSocket(1234);
while (true) {
Socket socket = serverSocket.accept();
OutputStream outputStream = socket.getOutputStream();
String message = "欢迎光临!";
outputStream.write(message.getBytes());
outputStream.close();
socket.close();
}
}
}
```
5. 基于Java的UDP聊天室
Java示例
```java
import java.io.*;
import java.net.*;
public class UDPChatRoom {
public static void main(String[] args) throws IOException {
DatagramSocket socket = new DatagramSocket(5555);
byte[] buffer = new byte;
while (true) {
DatagramPacket packet = new DatagramPacket(buffer, buffer.length);
socket.receive(packet);
String receivedMessage = new String(packet.getData(), 0, packet.getLength());
System.out.println("收到消息: " + receivedMessage);
DatagramPacket responsePacket = new DatagramPacket(packet.getData(), packet.getLength(), packet.getAddress(), packet.getPort());
socket.send(responsePacket);
}
}
}
```
6. 基于Java的进程间通信
Java示例
