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
服务器:

import socket

server = socket.socket()
server.bind(('10.7.156.115', 1024))
server.listen(512)

def send_picture():
    name = input('请输入要发送的图片名:')
    with open('./files/'+name, 'rb') as f:
        while True:
            picture = f.read(1024**3)
            # 发送完成后发送确认信息
            if not picture:
                print('图片发送完成!')
                conversation.send('图片发送完成!'.encode(encoding='utf-8'))
                break
            conversation.send(picture)

    # conversation.close()

def send_text():
    text = input('请输入要传输的文字:')
    conversation.send(text.encode(encoding='utf-8'))
    # conversation.close()

while True:
    print('开始监听!')
    conversation, addr = server.accept()
    print('收到会话请求!')

    while True:
        content = conversation.recv(1024).decode('utf-8')
        if content == '1':
            send_picture()
        elif content == '2':
            send_text()
        elif content == '3':
           conversation.close()
           print('已经断开会话!')
           break

客户端:

import socket

client = socket.socket()
client.connect(('10.7.156.115', 1024))

with open('./files/interface.txt', 'r', encoding='utf-8') as f:
    interface = f.read()

def recv_picture():
    content = client.recv(1024**3)
    data = bytes()
    while content:
        data += content
        content = client.recv(1024**3)
        # 发送完成后根据确认信息关闭接收
        if content == '图片发送完成!'.encode(encoding='utf-8'):
            print('图片接收完成')
            break

    name = input('请输入您想保持的图片名:')
    with open('./files/'+name, 'wb') as f:
        f.write(data)

def rece_text():
    message = client.recv(1024).decode('utf-8')
    with open('./files/message.txt', 'a', encoding='utf-8') as f:
        f.write(message + '\n')

while True:
    print(interface)
    value = input('请选择(1-3):')
    client.send(value.encode(encoding='utf-8'))
    if value == '1':
        recv_picture()
        continue
    elif value == '2':
        rece_text()
        continue
    elif value == '3':
        client.send('请关闭会话!'.encode(encoding='utf-8'))
        client.close()
        break
    else:
        print('请输入正确的选项!')
        continue

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!”}]

import requests
import re
import json

url = 'https://www.apiopen.top/satinApi?type=1&page=1'
response = requests.get(url)
re_str = r'"text":"(.*?)","user_id":.*?"name":"(.*?)","screen_name":'
content = re.findall(re_str, response.text)
# print(content)
list1 = []
for item in content:
    dict1 = {'name': '', 'text': ''}
    dict1['name'] = item[1]
    dict1['text'] = item[0]
    list1.append(dict1)

with open('./files/api_text.json', 'w', encoding='utf-8') as f:
    json.dump(list1, f)
with open('./files/api_text.json', 'r', encoding='utf-8') as f:
    content = json.load(f)
print(content)
