Question

我是python（和编程事物）的新手，所以我尝试练习不同类型的练习。其中之一是使用脚本（python3）下载流视频。问题是我不下载视频而是下载网页的html内容......任何人都可以帮我理解错误吗？

这是我的代码：

import Mail
from urllib.request import Request, urlopen
import urllib
import time
import requests

mail = Mail.Mail()

def download_file(url):
    local_filename = url.split('/')[-1]
    # NOTE the stream=True parameter
    r = requests.get(url, stream=True)
    with open(local_filename, 'wb') as f:
        for chunk in r.iter_content(chunk_size=1024):
            if chunk:  # filter out keep-alive new chunks
                f.write(chunk)
                # f.flush() commented by recommendation from J.F.Sebastian
    return local_filename


if __name__ == '__main__':

    url = 'https://youtu.be/xKsEKgAF7kE'


filename = download_file(url)
print(filename, " has been downloaded.")

不要注意像邮件一样的垃圾，这是我为进一步使用而创建的类，或无用的导入：我的第一个看起来不同，我没有使用请求lib，我的代码是不同的但结果是一样的（这段代码来自其他stackoverflow主题）。

非常感谢您的帮助！：）

**最好使用pytube模块并查看它内部。所以我认为这可能会对你有帮助**

    from pytube import YouTube
from pprint import pprint

yt = YouTube("http://www.youtube.com/watch?v=Ik-RsDGPI5Y")


print(yt.get_videos())


# The filename is automatically generated based on the video title.  You
# can override this by manually setting the filename.

# view the auto generated filename:
print(yt.filename)

# Pulp Fiction - Dancing Scene [HD]

# set the filename:
yt.set_filename('Enything')

# You can also filter the criteria by filetype.
print(yt.filter('flv'))

print(yt.filter(resolution='480p'))

video = yt.get('mp4', '720p')

# NOTE: get() can only be used if and only if one object matches your       criteria.
# for example:

print(yt.videos)

#[<Video: MPEG-4 Visual (.3gp) - 144p>,
# <Video: MPEG-4 Visual (.3gp) - 240p>,
# <Video: Sorenson H.263 (.flv) - 240p>,
# <Video: H.264 (.flv) - 360p>,
# <Video: H.264 (.flv) - 480p>,
# <Video: H.264 (.mp4) - 360p>,
# <Video: H.264 (.mp4) - 720p>,
# <Video: VP8 (.webm) - 360p>,
# <Video: VP8 (.webm) - 480p>]

# Since we have two H.264 (.mp4) available to us... now if we try to call get()
# on mp4...

video = yt.get('mp4')
# MultipleObjectsReturned: 2 videos met criteria.

# In this case, we'll need to specify both the codec (mp4) and resolution
# (either 360p or 720p).

# Okay, let's download it! (a destination directory is required)
video.download('/tmp/')

python脚本，下载HTML内容而不是流媒体视频
