How youtube-dl get video's real url on bilibili?

Question

To open https://github.com/ytdl-org/youtube-dl/tree/master/youtube_dl/extractor ,bilibili.py in it,i get bilibili.py source code,it help nothing.
It is no use for a newbie like me to look over and over at bilibili.py's source code.
It is difficult for me to understand how youtube-dl get video's real url on bilibili?
What is the principle for bilibili.py to extract video's real url on bilibili?
There are 421 lines in bilibili.py's source code,please simplify bilibili.py as a short single function such as getUrlFromBilibili.

url = "https://www.bilibili.com/video/av52135588?from=search&seid=5625791913889140593"
real_url = getUrlFromBilibili(url)
print(real_url)

Please fulfil the getUrlFromBilibili function and give some comments in it to show principle to get video's real url on bilibili.

def  getUrlFromBilibili(url):
    #make the function short as soon as possible

The lib is downloading the webpage and searching with regexes for the video url. — Simon, Dec 10 '19 at 20:46

Looks like you want to get only the url part without parameters. This can be achieved simply like this.

url = "https://www.bilibili.com/video/av52135588?from=search&seid=5625791913889140593"
real_url = url.split('?')[0]

//real_url = https://www.bilibili.com/video/av52135588

I believe the author wants the real VIDEO FILE url from the website url. – Alexandr Shurigin Dec 13 '19 at 12:41

There is no single real video file. It consists of multiple small video files that are streamed dynamically. – DinushaNT Dec 13 '19 at 12:44
What is the output for `wget https://www.bilibili.com/video/av52135588`? – Dec 16 '19 at 17:17
@scrapy It will just download the page containing that video. If you need to download the actual video file, it's a complex process which cannot be simplified into a single function. Whole purpose of the youtube-dl library is to download such files. – DinushaNT Dec 17 '19 at 11:12

You have said you need to use functions for that and need know principles. Bilibili site is like a youtube. There are lot videos in there. There for You have to program to get real url from any video url that you enter. I will show how to do that.

def  getUrlFromBilibili(url):
    real_url = url[:url.find('?')]
    return real_url;

URL = input("Copy and Paste your Bilibili url = ")
#https://www.bilibili.com/video/av52135588?from=search&seid=5625791913889140593
print("Real url is = ", getUrlFromBilibili(URL))

output -:

Copy and Paste your Bilibili url = https://www.bilibili.com/video/av52135588?from=search&seid=5625791913889140593

Real url is = https://www.bilibili.com/video/av52135588

Now I am going to explain this code

#Start of the function

def  getUrlFromBilibili(url):      #This the function which we use to store our url
    real_url = url[:url.find('?')] #In here we remove all characters after '?' in your url including '?'
    return real_url;               #After that we return our shorten url 

#End of the function


URL = input("Copy and Paste your Bilibili url")  #In here You can Enter any video url from Bilibili.com

print("Real url is = ", getUrlFromBilibili(URL))         #After all actions shorten url is displaying in here.
