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(('10.7.187.55', 8888))

server.listen(100)
print('开始监听。')

while 1:
    conversation, address = server.accept()

    while 1:
        get_data = conversation.recv(1024)
        print('客户端:', get_data.decode('utf-8'))
        if get_data.decode('utf-8') == '拜拜':
            print('客户端已退出连接,等待下次客户端请求:', address)
            break

        send_data = input('服务器:')
        conversation.send(send_data.encode('utf-8'))
        if send_data == '拜拜':
            print('已断开本次连接,等待下次客户端请求:')
            break

客户端:

import socket

client = socket.socket()

client.connect(('10.7.187.55', 8888))

while 1:
    send_data = input('客户端:')
    client.send(send_data.encode('utf-8'))
    if send_data == '拜拜':
        print('已断开本次连接。')
        break

    get_data = client.recv(1024)
    print('服务器:', get_data.decode('utf-8'))
    if get_data.decode('utf-8') == '拜拜':
        print('服务器已断开本次连接。')
        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
import json

server = socket.socket()
server.bind(('10.7.187.55', 8888))

server.listen(200)
print('开始监听:')

while 1:
    conversation, adress = server.accept()

    while 1:
        get_data = conversation.recv(1024)
        print('客户端:', get_data.decode('utf-8'))
        if get_data.decode('utf-8') == '3':
            send_data = '拜拜!'
            conversation.send(send_data.encode('utf-8'))
            print('当前客户端已断开连接。', adress)
            break
        elif get_data.decode('utf-8') == '1':
            with open('王也.jpg', 'rb') as f:
                send_data = f.read()
                conversation.send(send_data)
            print('已发送图片。')
        elif get_data.decode('utf-8') == '2':
            with open('files/测试文件.json', 'r', encoding='utf-8') as f:
                content = json.load(f)
                conversation.send(str(content).encode('utf-8'))
                print('已发送文件。')

客户端:

import socket

client = socket.socket()
client.connect(('10.7.187.55', 8888))

while 1:
    send_data = input('客户端:')
    client.send(send_data.encode('utf-8'))

    if send_data == '3':
        print('已退出连接。')
        break
    elif send_data == '1':
        content = bytes()
        while 1:
            get_data = client.recv(1024)
            content += get_data
            print(len(get_data))
            # if len(get_data) == 39:
            if len(get_data) < 1024:
                break

        with open('接收文件/图片1.jpg', 'bw') as f:
            f.write(content)
            print('接收图片成功。')
    elif send_data == '2':
        get_data = client.recv(1024)
        print('服务器:', get_data.decode())
