day18 网络编程作业

1. 客户端和服务器聊天，可以一直聊天，直到一方发送’拜拜’。然后就可以和下一个人一直聊

#服务器端：
import socket
serve = socket.socket()
serve.bind(("10.7.187.128",9092))
serve.listen(1024)
print("开始监听")
while True:
    conversation,addr = serve.accept()
    while True:
        data = conversation.recv(1024)
        print("客户端：",data.decode("utf-8"))
        if data.decode("utf-8") == "拜拜":
            conversation.send("拜拜".encode(encoding="utf-8"))
            print("下一会话者接听")
            break
        message = input("输入回话内容：")
        conversation.send(message.encode(encoding="utf-8"))
        if message == "拜拜":
            print("下一会话者接听")
            break
    conversation.close()

#客户端：
import socket
client = socket.socket()
client.connect(("10.7.187.128",9092))
while True:
    message = input("输入内容：")
    client.send(message.encode(encoding="utf-8"))
    if message == "拜拜":
        print("断开会话连接")
        break
    data = client.recv(1024)
    print("服务器：",data.decode("utf-8"))
    if data.decode("utf-8") == "拜拜":
        client.send("拜拜".encode(encoding="utf-8"))
        break
client.close()

2.客户端给服务器发送请求，请求成功后，客户端给服务发送‘1’，服务器就给客户端发送一张图片；客户端给服务发送‘2’，服务器就给客户端返回一个json文件中的内容;客户端给服务发送‘3’, 服务器返回’拜拜’,然后断开连接

服务器：
import socket
serve = socket.socket()
serve.bind(("10.7.187.128",9096))
serve.listen(1024)
print("开始监听")
while True:
    conversation,addr = serve.accept()
    message = "请输入编号1：获取图片；2：获取json文件；3：拜拜"
    conversation.send(message.encode(encoding="utf-8"))
    data = conversation.recv(1024)
    print("客户端：", data.decode("utf-8"))
    while True:
        data = conversation.recv(1024)
        print("客户端：",data.decode("utf-8"))
        if data.decode("utf-8") =="1":
            with open("-4d29fda630106db2.jpg","rb") as f:
                content = f.read()
                conversation.send(content)
        elif data.decode("utf-8") == "2":
            with open("home.json","rb") as f:
                content = f.read()
                conversation.send(content)
        elif data.decode("utf-8") == "3":
            conversation.send("拜拜".encode(encoding="utf-8"))
        else:
            message = "请输入编号1：获取图片；2：获取json文件；3：拜拜"
            conversation.send(message.encode(encoding="utf-8"))
    conversation.close()

客户端：
import socket
client = socket.socket()
client.connect(("10.7.187.128",9096))
message = "我要请求"
client.send(message.encode(encoding="utf-8"))
while True:
    re_data = client.recv(1024)
    print("服务器：",re_data.decode("utf-8"))
    message = input("输入内容：")
    client.send(message.encode(encoding="utf-8"))
    data1 = bytes()
    if message == "1":
        while True:
            data = client.recv(1024)
            data1 += data
            if not data:
                break
        print("数据接收完了")
        with open("回复1图片.jpg","wb") as f:
            f.write(data1)
    elif message == "2":
        while True:
            data = client.recv(1024)
            data1 += data
            if not data:
                break
        print("数据接收完了")
        with open("new_home.json","w",encoding="utf-8") as f:
            f.write(data1)
    elif message == "3":
        break
    else:
        print("输入有误，请重新请求")
        break
