For this course, I save the links in the txtby --save command, and find something interesting
The chapater 1 have 7 videos lecture, the first lecture url link is look like
So I import urllib to see what happened in the python, the code was
python 3.6.4
import urllib.requestreq = urllib.request.Request('https://a1003.udemycdn.com/2019-04-13_09-32-30-5624f70ce5a6e8ac074bf56200683a63/WebHD_720p.mp4?secure=zmhUcFzwnfxqrOLAKRipng%3D%3D%2C1573989415',headers = {'User-Agent':'Mozilla/5.0'})urllib.request.urlopen(req)
it wiil raise the following error
But If I copy the second links to the Chrome, it can be downloaded indeed
So I think maybe there maybe some setting to the urlib.request library, Cause I even used the requests library which rewrited based on urllib.request , it still can be downloaded
