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
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

server.bind(('10.7.187.58', 8083))

server.listen(312)

while True:
    conversation, addr = server.accept()

    while True:
        re_data = conversation.recv(1024)
        print('客户端:', re_data.decode('utf-8'))
        message = input('服务器')
        conversation.send(message.encode('utf-8'))
        if re_data.decode('utf-8') == '拜拜':
            break

客户端
import socket
client = socket.socket()
client.connect(('10.7.187.58', 8083))
while True:
    message = input('客户端')
    client.send(message.encode('utf-8'))
    data = client.recv(1024)
    print('服务器：', data.decode('utf-8'))
    if message == '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
import json
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

server.bind(('10.7.187.58', 8083))

server.listen(312)

while True:
    conversation, addr = server.accept()

    while True:
        re_data = conversation.recv(1024)
        print('客户端:', re_data.decode('utf-8'))
        if re_data.decode('utf-8') == '1':
            with open('王爷.jpg', 'rb') as f:
                message = f.read()
            conversation.send(message)
            break
        elif re_data.decode('utf-8') == '2':
            with open('1.json', encoding='utf-8') as f:
                message = json.load(f)
            conversation.send(str(message).encode('utf-8'))
        if re_data.decode('utf-8') == '3':
            conversation.send('拜拜'.encode('utf-8'))
            break
    conversation.close()

客户端
import socket
import json
client = socket.socket()
client.connect(('10.7.187.58', 8083))
byte = bytes()
while True:
    message = input('客户端')
    client.send(message.encode('utf-8'))
    if message == '1':
        while True:
            data = client.recv(1024)
            byte += data
            if not data:
                break
        with open('new2.jpg', 'bw') as f:
            f.write(byte)
            break
    elif message == '2':
        data = client.recv(1024)
        with open('new1.json', 'w', encoding='utf-8') as f:
            json.dump(data.decode('utf-8'), f)
        with open('new1.json', encoding='utf-8') as f:
            print(f.read())
    else:
        print((client.recv(1024)).decode('utf-8'))
        break
client.close()
