Python3, download file from url by button click

问题:

I need to download file from link like this https://freemidi.org/getter-13560

But I cant use urllib.request or requests library cause it downloads html, not midi. Is there is any solution? And also here is the link with the button itself link

By adding the proper headers and using session we can download and save the file using request module.

import requests

headers = {
            "Host": "freemidi.org",
            "Connection": "keep-alive",
            "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36",
            "Accept-Encoding": "gzip, deflate, br",
            "Accept-Language": "en-US,en;q=0.9",
           }

session = requests.Session()

#the website sets the cookies first
req1 = session.get("https://freemidi.org/getter-13560", headers = headers)

#Request again to download
req2 = session.get("https://freemidi.org/getter-13560", headers = headers)
print(len(req2.text))     # This is the size of the mdi file

with open("testFile.mid", "wb") as saveMidi:
    saveMidi.write(req2.content)
