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

1、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。

2、用requests发送get请求，获得下载链接

3、将下载到的文件保存到本地。

5、实现过程

1、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 = {

    try:

    else:

        date = re.findall('readyVideoUrl":"(.*?)","readyDuration', response.text)[0]

        date1=requests.get(url=date,headers=headers).content

#将爬取到的数据写入文件     

         with open('video\\'+name+'.mp4',mode='wb') as f:

            f.write(date1)

2、抖音视频爬虫

import requests

import re

import os

#新建文件夹

filename='video\\'

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

#定制请求头
