| 5 ============================= | |

| 7 This file contains an implementation of the SSLAdapter originally demonstrated | |
| 8 in this blog post: | |
| 9 https://lukasa.co.uk/2013/01/Choosing_SSL_Version_In_Requests/ | |
| 10 | |
| 11 """ | |
| 12 import requests | |
| 13 | |
| 14 from requests.adapters import HTTPAdapter | |
| 15 | |
| 16 from .._compat import poolmanager | |

| 19 class SSLAdapter(HTTPAdapter): | |
| 20 """ | |
| 21 A HTTPS Adapter for Python Requests that allows the choice of the SSL/TLS | |
| 22 version negotiated by Requests. This can be used either to enforce the | |
| 23 choice of high-security TLS versions (where supported), or to work around | |
| 24 misbehaving servers that fail to correctly negotiate the default TLS | |
| 25 version being offered. | |
| 26 | |
| 27 Example usage: | |
| 28 | |
| 29 >>> import requests | |
| 30 >>> import ssl | |
| 31 >>> from requests_toolbelt import SSLAdapter | |
| 32 >>> s = requests.Session() | |
| 33 >>> s.mount('https://', SSLAdapter(ssl.PROTOCOL_TLSv1)) | |
| 34 | |
| 35 You can replace the chosen protocol with any that are available in the | |
| 36 default Python SSL module. All subsequent requests that match the adapter | |
| 37 prefix will use the chosen SSL version instead of the default. | |
| 38 | |
| 39 This adapter will also attempt to change the SSL/TLS version negotiated by | |
| 40 Requests when using a proxy. However, this may not always be possible: | |
| 41 prior to Requests v2.4.0 the adapter did not have access to the proxy setup | |
| 42 code. In earlier versions of Requests, this adapter will not function | |
| 43 properly when used with proxies. | |
