The Requests Toolbelt

This is just a collection of utilities for python-requests_, but don't really belong in requests proper. The minimum tested requests version is 2.1.0. In reality, the toolbelt should work with 2.0.1 as well, but some idiosyncracies prevent effective or sane testing on that version.

pip install requests-toolbelt to get started!

multipart/form-data Encoder

The main attraction is a streaming multipart form-data object, MultipartEncoder. Its API looks like this:

.. code-block:: python

from requests_toolbelt import MultipartEncoder
import requests

m = MultipartEncoder(
    fields={'field0': 'value', 'field1': 'value',
            'field2': ('filename', open('file.py', 'rb'), 'text/plain')}
    )

r = requests.post('http://httpbin.org/post', data=m,
                  headers={'Content-Type': m.content_type})

You can also use multipart/form-data encoding for requests that don't require files:

.. code-block:: python

from requests_toolbelt import MultipartEncoder
import requests

m = MultipartEncoder(fields={'field0': 'value', 'field1': 'value'})

r = requests.post('http://httpbin.org/post', data=m,
                  headers={'Content-Type': m.content_type})

Or, you can just create the string and examine the data:

.. code-block:: python

# Assuming `m` is one of the above
m.to_string()  # Always returns unicode

User-Agent constructor

You can easily construct a requests-style User-Agent string::

from requests_toolbelt import user_agent

headers = {
    'User-Agent': user_agent('my_package', '0.0.1')
    }

r = requests.get('https://api.github.com/users', headers=headers)

SSLAdapter

The SSLAdapter was originally published on Cory Benfield's blog_. This adapter allows the user to choose one of the SSL protocols made available in Python's ssl module for outgoing HTTPS connections:

.. code-block:: python

from requests_toolbelt import SSLAdapter
import requests
import ssl

s = requests.Session()
s.mount('https://', SSLAdapter(ssl.PROTOCOL_TLSv1))

cookies/ForgetfulCookieJar

The ForgetfulCookieJar prevents a particular requests session from storing cookies:

.. code-block:: python

from requests_toolbelt.cookies.forgetful import ForgetfulCookieJar

session = requests.Session()
session.cookies = ForgetfulCookieJar()
