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)

import socket
server = socket.socket()
server.bind(('10.7.187.72', 8086))
server.listen(1024)
while True:
    conversation, addr = server.accept()
    print('接受到请求!')
    while True:
        recv_data = conversation.recv(1024)
        print('客户端:', recv_data.decode('utf-8'))
        if recv_data.decode('utf-8') == '拜拜':
            break
        message = input('服务器:')
        conversation.send(message.encode('utf-8'))
        if message == '拜拜':
            break

(客户端)

import socket

client = socket.socket()
client.connect(('10.7.187.72', 8086))
while True:
    message = input('客户端:')
    client.send(message.encode('utf-8'))
    if message == '拜拜':
        break
    recv_data = client.recv(1024)
    print('客户端:', recv_data.decode('utf-8'))
    if recv_data.decode('utf-8') == '拜拜':
        break

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
server = socket.socket()
server.bind(('10.7.187.72', 8100))
server.listen(1024)
while True:
    conversation, addr = server.accept()
    print('接收到请求!')
    while True:
        recv_data = conversation.recv(1024)

        if recv_data.decode('utf-8') == '1':
            with open('./okok.jpg', 'rb') as f:
                content = f.read()
                conversation.send(content)
                print('客户端', recv_data.decode('utf-8'))
        elif recv_data.decode('utf-8') == '2':
            with open('./1234.json', 'r', encoding='utf-8') as f1:
                json1 = f1.read()
                print(json1)
                conversation.send(json1.encode('utf-8'))
                print('客户端','2')
        elif recv_data.decode('utf-8') == '3':
            conversation.send('拜拜'.encode('utf-8'))
            break

(客户端)

import socket
import json

def get_picture():
    data = bytes()
    while True:
        re_data = client.recv(1024)
        data += re_data
        with open('./图片.jpg', 'bw') as f:
            f.write(data)
def json1_get():
    re_data = client.recv(1024)
    json1 = re_data.decode('utf-8')
    print(json1)
    with open('./接受.json', 'w') as f:
        json.dump(json1, f)
    print('2(1)')

client = socket.socket()
client.connect(('10.7.187.72', 8100))

while True:
    message = input('客户端:')
    client.send(message.encode('utf-8'))
    data = bytes()
    # while True:
    #     print('2')
    if message == '1':
        print('接受图片!')
        get_picture()
    if message == '2':
        print('接受json文件')
        json1_get()
    if message == '3':
        re_data = client.recv(1024)
        print('服务器:', re_data.decode('utf-8'))
