1、开发工具

python3.9

requests库

其他一些python内置库

PyCharm

2、第三方库

安装第三方库

pip install requests

3、实现思路

利用tkinter库实例化一个GUI界面，包含提示框、输入框、选择按钮、功能按钮。

用requests发送get请求，获得下载链接

将下载到的文件保存到本地。

4、实现效果

5、实现过程

B站视频爬虫

import requests
import re
import os
#判断是否存在文件夹video，不存在，则创建一个
filename='video\\'
if not os.path.exists(filename):
    os.mkdir(filename)
#定义一个爬虫函数，供主函数调用
def UrlCrawler(url,name):
 
#定制请求头   
      headers = {

2、抖音视频爬虫

import requests

import re

import os

#新建文件夹

if not os.path.exists(filename):

    os.mkdir(filename)

#定义函数，供主函数调用

def TikTok(url,name):

    response = requests.get(url=url)

    response = response.url

#检查主函数输入的链接是否正确 

    try:

        id = re.findall('video/(.*)/\?', response)[0]

    except IndexError:

        return 1

    # Https://www.douyin.com/video/7197438641520610595

    print(id)

    Url = 'https://www.douyin.com/video/' + id
