#94944 — Parsing multipart HTTP response

Hi,

I searched without succeeding a Python resource that is capable of parsing an HTTP multipart/mixed response stream, preferably as a generator that yields headers + content for each part.

Google and friends didn't find or I didn't use the appropriate term.

Any hint will be appreciated.

Ah, aiohttp does something similar to what I need but requires Python 3.3 + when I'm stuck with Pyton 2.7 on that project.

Hardly my field but how about:-

https://pypi.python.org/pypi/requests-toolbelt/0.3.1
https://pypi.python.org/pypi/multipart/

My fellow Pythonistas, ask not what our language can do for you, ask

Thanks Mark,

"multipart" is close to what I need and will give me some inpiration. Unfortunately, it works for multipart/form-data server-side handling, when I'm searching for a multipart/mixed client side handling of a response. In addition, it does not yield the headers specific to each data chunk from the response, and I need those headers.

To be more specific, I'm buiding with the excellent "requests" lib and Python 2.7 (sorry, I can't go to Python 3.x at the moment) a client library for the documents database MarkLogic 8 that provides some APIs with multipart/mixed responses like this one:

http://docs.marklogic.com/REST/POST/v1/eval

In other words I need something that may be used like this :

response = requests.post(some_uri, params=some_params, stream=True)
if response.headers['content-type'].startswith('multipart/mixed'):
    boundary = parse_boundary(response.headers['content-type'])

    generator = iter_multipart_response(response, boundary)
    for part_headers, part_body in generator:
        # I'm consuming parsed headers and bodies from response
        # In my application code

Cheers
