Python 简单建立UDPTCP连接

Python 简单建立UDP/TCP连接一、UDP 01-Server 【Python 简单建立UDPTCP连接】from socket import *serverPort=12005serverSocket=socket(AF_INET,SOCK_DGRAM)serverSocket.bind(("127.0.0.1",serverPort))print("The server is ready to receive...")while(1):message,clientAddress=serverSocket.recvfrom(2048)modifiedMessage=message.upper()serverSocket.sendto(modifiedMessage,clientAddress) 02-Client from socket import *serverName="127.0.0.1"serverPort=12005while(1):clientSocket=socket(AF_INET,SOCK_DGRAM)message=input("Input lowercase sentence:").encode()clientSocket.sendto(message,(serverName,serverPort))modifiedMessage,serverAddress=clientSocket.recvfrom(2048)print("From Server: "+str(modifiedMessage,"utf-8"))clientSocket.close() 二、TCP 01-Server from socket import *serverPort=12010serverSocket=socket(AF_INET,SOCK_STREAM)serverSocket.bind(("127.0.0.1",serverPort))serverSocket.listen(1)print("The server is ready to receive...")while(1):connectionSocket,addr=serverSocket.accept()message=connectionSocket.recv(1024)capitalizedMessage=message.upper()connectionSocket.send(capitalizedMessage)connectionSocket.close() 02-Client from socket import *serverName="127.0.0.1"serverPort=12010while(1):clientSocket=socket(AF_INET,SOCK_STREAM)clientSocket.connect((serverName,serverPort))message=input("Input lowercase sentence:").encode()clientSocket.send(message)modifiedMessage=clientSocket.recv(1024)print("From Server: "+str(modifiedMessage,"utf-8"))clientSocket.close()
