Why is not the full file downloaded via python url?

Question

Python

I download the file via url from Bitrix. If I just click on the link in the browser, then a full-fledged file is downloaded. If I start using python, then a corrupted 22kb file is downloaded

files = []
for file in result:
    files.append(url+file['downloadUrl'])
wget.download(files[0], 'lead_2020.pdf')

url itself https://bitrix24.ru/bitrix/components/bitrix/crm.d...

Answer 1

You may need authorization. What is downloaded through the browser if you delete all site data?
