requests-seekable

Open HTTP responses as seekable file objects. When seek() is called, a new request is made with the Range header set.

This is useful for extracting files from large web-based .zip archives.

Usage

If your existing code looks like this:

import requests

response = requests.get('https://example.com', stream=True)
fileobj = response.raw  # not seekable :(

Then replace response.raw with SeekableResponse(response):

import requests
import requests_seekable

response = requests.get('https://example.com', stream=True)
fileobj = requests_seekable.SeekableResponse(response)  # seekable :)

If the server doesn't support Range headers, then SeekableResponse initializer raises a SeekError exception. This type of exception (a subclass of OSError) is also raised from SeekableResponse.seek() in the following cases:

• If the given whence value isn't SEEK_SET (0), SEEK_CUR (1) or SEEK_END (2); or
• If the given whence value is SEEK_END but the content length isn't known; or
• If the response status isn't 206 "Partial Content" or 416 "Range Not Satisfiable".
