requests_toolbelt.ssl_adapter
|
|
=============================
|
|
|
|
This file contains an implementation of the SSLAdapter originally demonstrated
|
|
in this blog post:
|

https://lukasa.co.uk/2013/01/Choosing_SSL_Version_In_Requests/
|
|
|
|
"""
|
|
import requests
|
|
|
|
from requests.adapters import HTTPAdapter
|
|
|
|
from .._compat import poolmanager
|
|
|
|
|
|
class SSLAdapter(HTTPAdapter):
|
|
"""
|
|
A HTTPS Adapter for Python Requests that allows the choice of the SSL/TLS
|
|
version negotiated by Requests. This can be used either to enforce the
|
|
choice of high-security TLS versions (where supported), or to work around
|
|
misbehaving servers that fail to correctly negotiate the default TLS
|
|
version being offered.
|
|
|
|
Example usage:
|
|
|
|
>>> import requests
|
|
>>> import ssl
|
|
>>> from requests_toolbelt import SSLAdapter
|
|
>>> s = requests.Session()
|
|
>>> s.mount('https://', SSLAdapter(ssl.PROTOCOL_TLSv1))
|
|
|
|
You can replace the chosen protocol with any that are available in the
|
|
default Python SSL module. All subsequent requests that match the adapter
|
|
prefix will use the chosen SSL version instead of the default.
|
|
|
|
This adapter will also attempt to change the SSL/TLS version negotiated by
|
|
Requests when using a proxy. However, this may not always be possible:
|
|
prior to Requests v2.4.0 the adapter did not have access to the proxy setup
|
|
code. In earlier versions of Requests, this adapter will not function
|
|
properly when used with proxies.
