python实现爬取哔哩哔哩视频代码并保存到本地文件夹D:\2233中

以下是Python代码实现爬取哔哩哔哩视频并保存到本地文件夹D:\2233中的操作步骤：

import requests
from contextlib import closing

# 视频链接地址
url = 'https://upos-sz-mirrorcos.bilivideo.com/upgcxcode/09/12/232461209/232461209-1-16.mp4?e=ig8euxZM2rNcNbhjhwbNv8BqBWNvNbhK38W7MgugEnNcXBB_&deadline=1613735034&gen=playurl&nbs=1&oi=3071608497&os=cosbv&platform=html5&trid=cd29dfeb625e482ba9e9d8c973a3dc3du&uipk=5&upsig=8c7c15eef6b5ac9d44f0f558be0ea29f'

# 本地文件路径及文件名
local_path = 'D:/2233/Python.mp4'

with closing(requests.get(url, stream=True)) as response:
    chunk_size = 1024  # 单次请求最大值
    content_size = int(response.headers['content-length'])  # 内容体总大小
    if response.status_code == 200:  # 判断是否响应成功
        print('文件大小:%0.2f MB' % (content_size / chunk_size / 1024))  # 输出文件大小
        with open(local_path, 'wb') as file:
            for data in response.iter_content(chunk_size=chunk_size):
                file.write(data)
                print('下载中：%.2f%%' % (file.tell() / content_size * 100), end='\r')
    else:
        print('链接异常')

如此实现，便可完成对指定视频的爬取并保存到本地指定路径的操作。
