写一个服务器以及客户端能选择发送图片以及自动回复消息：
服务器端：
from socket import *
import os
server = socket()
server.bind(('10.7.181.89', 6688))
server.listen(100000)
while True:
connect, address = server.accept()
while True:
data = connect.recv(1024000)
if data.decode(encoding='utf-8') == '2':
connect.send(str(os.listdir('files')).encode())
data2 = connect.recv(1024000)
name = data2.decode(encoding='utf-8')
print(name)
with open('files/'+name, 'rb') as f:
connect.send(f.read())
break
else:
print(data.decode(encoding='utf-8'))
connect.send(data)
connect.close()
客户端：
from socket import *
client = socket()
client.connect(('10.7.181.89', 6688))
while True:
with open('test1.txt', 'r', encoding='utf-8') as f:
print(f.read())
num = input(':')
if num == '1':
send_message = input('客户端:')
client.send(send_message.encode())
re_data = client.recv(1024000)
print(re_data.decode(encoding='utf-8'))
if num == '2':
send_message1 = '2'
client.send(send_message1.encode())
re_data = client.recv(1024000)
print(re_data.decode(encoding='utf-8'))
choices = input('请输入需要下载图片的完整名字：')
client.send(choices.encode())
# while True:
re_data = client.recv(1024000)
with open(choices, 'ab') as f:
f.write(re_data)
else:
print('请重新选择：')
client.close()
