Browser user-agent detection

This library parses browser user-agent strings with data from user-agent-string.info.

This library is loosely based on the work by Hicro Kee (hicrokee AT gmail DOT com) and Michal Molhanec (http://molhanec.net).

Usage:

::

from uaparser import UA, UAParser parser = UAParser() parser.update_data() ua = UA(parser, user_agent_string) print ua.is_robot() # returns empty dictionary if robot is not detected print ua.get_browser_details() # returns empty dictionary, or browser details print ua.get_device_type() # returns dict containing device type fields print ua.get_os_details()

Or alternatively,

print ua.parse() # returns all parsed fields for the UA string

Django integration

As running a large number of regexes takes a long time, Django integration uses caching.

Usage:

::

from uaparser.django.caching_ua_parser import parse_user_agent parsed = parse_user_agent(request.META.get("HTTP_USER_AGENT"))

parse_user_agent fetches all user-agent fields (i.e it calls ua.parse()).

Settings:

• UA_CACHE_DIRECTORY: directory for data file ("cache.pickle"). Mandatory.
• UA_CACHE_NAME: defaults to "default". Defines custom Django cache name.
• UA_CACHE_PREFIX: defaults to "parse_ua". Key prefix for cache.
• UA_CACHE_TIMEOUT: defaults to 48 hours. Cache key timeout in seconds.

Middleware: add uaparser.django.middleware.UAParserMiddleware to MIDDLEWARE_CLASSES.

Context processor: to add parsed_ua variable to context, add uaparser.django.context_processor.add_parsed_ua to CONTEXT_PROCESSORS. This does nothing if UAParserMiddleware is not enabled.
