众所周知，网页版的B站无法下载视频，然本人喜欢经常在B站学习，奈何没有网时，无法观看视频资源，手机下载后屏幕太小又不想看，遂写此程序以解决此问题
话不多说，进入正题
1.在电脑上下载python的开发环境，点一下，观看具体步骤
2.下载pycharm开发工具,点一下观看具体步骤
3.同时按键盘上的win键与r键，在弹出的对话框中输入cmd
点击确定进入cmd命令行，在里面输入pip install you-get,之后按键盘enter键，进行you-get的下载，下载完后退出cmd
4.打开pycharm开发工具，新建一个python file命名为bilibili,把下面的代码复制进去，关于pycharm开发工具的使用，点我一下，观看教程
import sys
import you_get
from multiprocessing import Pool
#url ='你要下载的视频链接'
#path='你要把视频保存到哪里'
url = 'https://www.bilibili.com/video/BV13s411371G?p='
path = 'D:/Bzhan/openstack'
total=14
def down1():
start_url = url
path1 = path
for i in range(1, 3, 1):
url1 = start_url + str(i)
download(url1, path1)
def down2():
start_url = url
path1 = path
for i in range(3, 5, 1):
url1 = start_url + str(i)
download(url1, path1)
def down3():
start_url = url
path1 = path
for i in range(5, 7, 1):
url1 = start_url + str(i)
download(url1, path1)
def down4():
start_url = url
path1 = path
for i in range(7, 9, 1):
url1 = start_url + str(i)
download(url1, path1)
def down5():
start_url = url
path1 = path
for i in range(9, 11, 1):
url1 = start_url + str(i)
download(url1, path1)
def down6():
start_url = url
path1 = path
for i in range(11, 13, 1):
url1 = start_url + str(i)
download(url1, path1)
def down7():
start_url = url
path1 = path
for i in range(13, 15, 1):
url1 = start_url + str(i)
download(url1, path1)
def down8():
start_url = url
path1 = path
for i in range(35, 40, 1):
url1 = start_url + str(i)
download(url1, path1)
def download(url, path):
sys.argv = ['you-get', '-o', path, url]
you_get.main()
def main():
po = Pool(8)
po.apply_async(down1)
po.apply_async(down2)
po.apply_async(down3)
po.apply_async(down4)
po.apply_async(down5)
po.apply_async(down6)
po.apply_async(down7)
po.apply_async(down8)
po.close()
po.join()
if __name__ == '__main__':
main()
接下来就可以运行程序，下载视频了
5.下面这个程序也能实现下载B站视频的功能，不过下载速度简直无语,称的上龟速
import you_get
import sys
import you_get
def download(url,path):
sys.argv=['you-get','-o',path,url]
you_get.main()
if __name__=='__main__':
start_url='https://www.bilibili.com/video/BV13s411371G?p='
path = 'D:/Bzhan/openstack'
for i in range(1,14,1):
url=start_url +str(i)
download(url,path)
