TCP：长连接，安全可靠，一般不会丢包，但是会发生黏包，面向流的传输，长度没有限制，超长的数据包会被拆包发送
#server.py import socket sk = socket.socket() sk.bind(("127.0.0.1",8080)) sk.listen() conn,addr = sk.accept() ret = conn.recv(1024) print(ret.decode("utf-8")) conn.send(b"server") conn.close() sk.close() #client.py import socket sk = socket.socket() sk.connect(("127.0.0.1",8080)) sk.send(b"clent") ret = sk.recv(1024).decode("utf-8") sk.close()
UDP：短链接，不可靠，会发生丢包，不会黏包，面向消息，长度有限制，超过限制，超过的部分就不发送
#server.py import socket sk = socket.socket(type=socket.SOCK_DGRAM) sk.bind(("127.0.0.1",8080)) msg,addr = sk.recvfrom(1024) msg = msg.decode("utf-8") print(msg) sk.sendto(b"server",addr) sk.close() #client.py import socket sk = socket.socket(type=socket.SOCK_DGRAM) ip_port = ("127.0.0.1",8080) sk.sendto(b"client",ip_port) msg,addr = sk.recvfrom(1024) print(msg.decode("utf-8"))
