服务器套接字

import socket
import time
# 第一题:
# 写一个客户端和服务器的套接字:
# 客户端连接服务器后展示界面:
# ===========================
# 1. 需要图片
# 2. 需要文字
# 3.  通知结束
# ==========================
# 请选择:
# 如果客户端选1,服务器给客户端发送一张图片,客户端保存图片到本地
# 如果客户端选2,  服务器输入一段文字发送给客户端, 客户端将文字保存在一个message.txt文件中
# 如果客户端选3,通知服务器关闭连接,并且客户端结束

# 定义一个窗口打印

    # 延时两秒后服务器关闭
    print("正在关闭服务器")
    time.sleep(2)

问题二

import re

import json
# 第二题:
# 请求接口:https://www.apiopen.top/satinApi?type=1&page=1  获取网络数据。
# 将内容中所有的name和text对应的值取出,并且保存到一个json文件中,保存的格式:
# [{“name”:”张三”, “text”:”哈哈,让我们一起自由的飞翔”},
# {“name”:”喒你家玻璃”, “text”:”截图暂停,截到的将会是对你爱情的预言三词!”}]
url = 'https://www.apiopen.top/satinApi?type=1&page=1'
response = requests.get(url)
content = response.text

re_str2 = r'"text":"[^,]+'
item = re.findall(re_str, content)
item2 = re.findall(re_str2, content)
