# requests-toolbelt > A utility belt for advanced users of python-requests - **URL**: https://www.freshcrate.ai/projects/requests-toolbelt - **Author**: Ian Cordasco - **Category**: Developer Tools - **Latest version**: `1.0.0` (2026-04-21) - **License**: Apache 2.0 - **Source**: https://github.com/requests/toolbelt/blob/master/HISTORY.rst - **Homepage**: https://toolbelt.readthedocs.io/ - **Language**: Python - **GitHub**: 1,034 stars, 194 forks - **Registry**: pypi (`requests-toolbelt`) - **Tags**: `pypi` ## Description 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() Contributing ------------ Please read the `suggested workflow `_ for contributing to this project.
