socket简单通信2

服务端

import socket,time
from socket import SOL_SOCKET,SO_REUSEADDR
sk = socket.socket() #创建服务端socket套接字
sk.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)  #解决地址和端口被占用的情况
sk.bind(("127.0.0.1",8080)) #绑定服务器地址，端口号
sk.listen()  #监听  等待消息
conn,adree = sk.accept()   #接收客户端的连接
count = 0
while count < 10:
    #ret = conn.recv(1024)
    ret = float(conn.recv(1024).decode("utf-8"))
    print(ret)
    ret_time = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime(ret))
    # if ret == "再见":
    #     conn.send(bytes("再见",encoding="utf-8"))
    #     break
    # info = input(">>>")
    conn.send(bytes(ret_time,encoding="utf-8"))
    count += 1

    # ret = conn.recv(1024)      #接收客户端信息 参数一般为1024的整数倍
    # print(ret)
    # conn.send(b"server")       #向客户端发送消息
    # ret = conn.recv(1024)
    # print(ret.decode("utf-8"))
    # conn.send(bytes("来吧来吧！",encoding="utf-8"))
conn.close()               #关闭客户连接
sk.close()                 #关闭服务套接字（可选）

客户端

import socket,time
sk = socket.socket()      #创建客户套接字
sk.connect(("127.0.0.1",8080)) #尝试连接服务
count = 0
while count < 10:
    time.sleep(2)
    info = bytes(str(time.time()),encoding="utf-8")
    sk.send(info)
    ret = sk.recv(1024).decode("utf-8")
    print(ret)
    count += 1
    # if ret == "再见":
    #     sk.send(bytes("再见",encoding="utf-8"))
    #     break
    # sk.send(b"client")
    # ret = sk.recv(1024)
    # print(ret)
    # sk.send(bytes("约会不？",encoding="utf-8"))
    # ret = sk.recv(1024)
    # print(ret.decode("utf-8"))
sk.close()
