requests-toolbelt 0.1.0

A utility belt for advanced users of python-requests

requests toolbelt

This is just a collection of utilities that some users of python-requests might need but do not belong in requests proper.

multipart/form-data Encoder

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

from requests_toolbelt import MultipartEncoder

import requests


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

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

You can also use it to just plain use multipart/form-data encoding for requests that do not require files:

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})

You can also just use it to create the string to examine the data:

# Assuming `m` is one of the above

m.to_string()  # Always returns unicode

User-Agent constructor

You can easily construct your own 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 is an implementation of the adapter proposed over on @Lukasa’s blog, here. This adapter allows the user to choose one of the SSL protocols made available in Python’s ssl module for outgoing HTTPS connections.:

from requests_toolbelt import SSLAdapter

import requests
import ssl

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