一、server（服务器）

from socket import *
import os

path = 'picture\\'


def file_name(cpath):
    return os.listdir(cpath)


server = socket()
server.bind(('127.0.0.1', 1029))
server.listen(10)

while True:
    connect, address = server.accept()
    while True:
        recv_data = connect.recv(1024).decode()
        if recv_data == 'a':
            connect.send(input('==========服务器：').encode())
        elif recv_data == 'b':
            list1 = file_name(path)     # 返回list1文件名列表
            connect.send(str(list1).encode())
            recv_data1 = connect.recv(1024).decode()
            file1 = list1[int(recv_data1)-1]
            with open('.\picture\\' + file1, 'rb') as f:
                print('==========正在发送图片：', file1)
                connect.send(f.read())
                print('==========发送成功==========')
        elif recv_data == 'exit':
            connect.close()

二、client（客户端）

from socket import *

client = socket()
client.connect(('127.0.0.1', 1029))

while True:
    print('a.请求文字信息')
    print('b.请求图片信息')
    print('c.断开连接')
    send_message = input('请选择(a/b/c)：')
    client.send(send_message.encode())
    if send_message == 'a':
        recv_data = client.recv(1024).decode(encoding='utf-8')
        print('服务器：', recv_data)
    elif send_message == 'b':
        recv_data = client.recv(1024).decode(encoding='utf-8')
        list1 = eval(recv_data)
        # print(list1)
        for i in range(len(list1)):
            print(i+1, list1[i])
        send_message1 = input('请选择：')
        client.send(send_message1.encode())
        send_message2 = int(send_message1)
        while True:
            recv_data = client.recv(1024)
            with open('picture1\\' + list1[send_message2-1], 'ab') as f:
                f.write(recv_data)
            if len(recv_data) < 1024:
                print('==========成功接收==========')
                break

    elif send_message.encode() == 'c':
        client.close()
        print('连接断开')
        break
