Geolocation with GeoIP2¶
The GeoIP2 object is a wrapper for the MaxMind geoip2 Python
library. [1]
In order to perform IP-based geolocation, the GeoIP2 object requires
the geoip2 Python library and the GeoIP Country and/or City datasets
in binary format (the CSV files will not work!). Grab the
GeoLite2-Country.mmdb.gz and GeoLite2-City.mmdb.gz files and unzip them
in a directory corresponding to the GEOIP_PATH setting.
Additionally, it is recommended to install the libmaxminddb C library, so
that geoip2 can leverage the C library’s faster speed.
Example¶
Here is an example of its usage:
>>> from django.contrib.gis.geoip2 import GeoIP2
>>> g = GeoIP2()
>>> g.country('google.com')
{'country_code': 'US', 'country_name': 'United States'}
>>> g.city('72.14.207.99')
{'city': 'Mountain View',
'country_code': 'US',
'country_name': 'United States',
'dma_code': 807,
'latitude': 37.419200897216797,
'longitude': -122.05740356445312,
'postal_code': '94043',
'region': 'CA',
'time_zone': 'America/Los_Angeles'}
>>> g.lat_lon('salon.com')
(39.0437, -77.4875)
>>> g.lon_lat('uh.edu')
(-95.4342, 29.834)
>>> g.geos('24.124.1.80').wkt
'POINT (-97 38)'
API Reference¶
-
class
GeoIP2(path=None, cache=0, country=None, city=None)¶
The GeoIP object does not require any parameters to use the default
settings. However, at the very least the GEOIP_PATH setting
should be set with the path of the location of your GeoIP datasets. The
following initialization keywords may be used to customize any of the
defaults.
| Keyword Arguments | Description |
|---|---|
path |
Base directory to where GeoIP data is located or the
full path to where the city or country data files
(.mmdb) are located. Assumes that both the city and
country datasets are located in this directory;
overrides the GEOIP_PATH setting. |
cache |
The cache settings when opening up the GeoIP datasets. May
be an integer in (0, 1, 2, 4, 8) corresponding to the
MODE_AUTO, MODE_MMAP_EXT, MODE_MMAP, and
GEOIP_INDEX_CACHE MODE_MEMORY C API settings,
respectively. Defaults to 0 (MODE_AUTO). |
country |
The name of the GeoIP country data file. Defaults
to GeoLite2-Country.mmdb. Setting this keyword
overrides the GEOIP_COUNTRY setting. |
city |
The name of the GeoIP city data file. Defaults to
GeoLite2-City.mmdb. Setting this keyword overrides
the GEOIP_CITY setting. |
Methods¶
Instantiating¶
-
classmethod
GeoIP2.open(path, cache)¶
This classmethod instantiates the GeoIP object from the given database path and given cache setting.
Querying¶
All the following querying routines may take either a string IP address
or a fully qualified domain name (FQDN). For example, both
'205.186.163.125' and 'djangoproject.com' would be valid query
parameters.
-
GeoIP2.city(query)¶
Returns a dictionary of city information for the given query. Some
of the values in the dictionary may be undefined (None).
-
GeoIP2.country(query)¶
Returns a dictionary with the country code and country for the given query.
-
GeoIP2.country_code(query)¶
Returns the country code corresponding to the query.
-
GeoIP2.country_name(query)¶
Returns the country name corresponding to the query.
Coordinate Retrieval¶
-
GeoIP2.coords(query)¶
Returns a coordinate tuple of (longitude, latitude).
-
GeoIP2.lon_lat(query)¶
Returns a coordinate tuple of (longitude, latitude).
-
GeoIP2.lat_lon(query)¶
Returns a coordinate tuple of (latitude, longitude),
-
GeoIP2.geos(query)¶
Returns a Point object corresponding to the
query.
Settings¶
GEOIP_PATH¶
A string specifying the directory where the GeoIP data files are
located. This setting is required unless manually specified
with path keyword when initializing the GeoIP2 object.
GEOIP_COUNTRY¶
The basename to use for the GeoIP country data file. Defaults to
'GeoLite2-Country.mmdb'.
GEOIP_CITY¶
The basename to use for the GeoIP city data file. Defaults to
'GeoLite2-City.mmdb'.
