从 URL 解压 rar 文件

Question

I didn't find any answer on how to extract specific files from RAR (not Zip) from URL.

For example, I have this URL whith quite heavy rar: http://cbr.ru/vfs/credit/forms/101-20200401.rar

What is the best way to take file from this RAR without downloading it to the disk?

Thanks

Answer 1

I tried many Python Libraries, but I finally found the solution using rarfile

1- install rarfile

2- use the following:

import urllib
import rarfile
from io import BytesIO

resp = urllib.request.urlopen('http://cbr.ru/vfs/credit/forms/101-20200401.rar')
r = rarfile.RarFile(BytesIO(resp.read()))
r.namelist()

The output will be:

['032020N1.DBF', 'NAMES.DBF', '032020B1.DBF']

3. To open file you should use r.open()
