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()
|
|
