Basic Host Lookup Example¶
This sample invokes and displays the results of a MaxMind "host lookup" via DXL.
- For more information see:
- http://dev.maxmind.com/geoip/geoip2/geolite2/
Prerequisites¶
- The samples configuration step has been completed (see Samples Configuration)
- The MaxMind DXL service is running (see Running)
Running¶
To run this sample execute the sample/basic/basic_host_lookup_example.py
script as follows:
python sample/basic/basic_host_lookup_example.py
The output should appear similar to the following:
{ "city": { "geoname_id": 5375480, "names": { "de": "Mountain View", "en": "Mountain View", "fr": "Mountain View", "ja": "\u30de\u30a6\u30f3\u30c6\u30f3\u30d3\u30e5\u30fc", "ru": "\u041c\u0430\u0443\u043d\u0442\u0438\u043d-\u0412\u044c\u044e", "zh-CN": "\u8292\u5ef7\u7ef4\u5c24" } }, "continent": { "code": "NA", "geoname_id": 6255149, "names": { "de": "Nordamerika", "en": "North America", "es": "Norteam\u00e9rica", "fr": "Am\u00e9rique du Nord", "ja": "\u5317\u30a2\u30e1\u30ea\u30ab", "pt-BR": "Am\u00e9rica do Norte", "ru": "\u0421\u0435\u0432\u0435\u0440\u043d\u0430\u044f \u0410\u043c\u0435\u0440\u0438\u043a\u0430", "zh-CN": "\u5317\u7f8e\u6d32" } }, "country": { "geoname_id": 6252001, "iso_code": "US", "names": { "de": "USA", "en": "United States", "es": "Estados Unidos", "fr": "\u00c9tats-Unis", "ja": "\u30a2\u30e1\u30ea\u30ab\u5408\u8846\u56fd", "pt-BR": "Estados Unidos", "ru": "\u0421\u0428\u0410", "zh-CN": "\u7f8e\u56fd" } }, "location": { "accuracy_radius": 1000, "latitude": 37.386, "longitude": -122.0838, "metro_code": 807, "time_zone": "America/Los_Angeles" }, "postal": { "code": "94035" }, "registered_country": { "geoname_id": 6252001, "iso_code": "US", "names": { "de": "USA", "en": "United States", "es": "Estados Unidos", "fr": "\u00c9tats-Unis", "ja": "\u30a2\u30e1\u30ea\u30ab\u5408\u8846\u56fd", "pt-BR": "Estados Unidos", "ru": "\u0421\u0428\u0410", "zh-CN": "\u7f8e\u56fd" } }, "subdivisions": [ { "geoname_id": 5332921, "iso_code": "CA", "names": { "de": "Kalifornien", "en": "California", "es": "California", "fr": "Californie", "ja": "\u30ab\u30ea\u30d5\u30a9\u30eb\u30cb\u30a2\u5dde", "pt-BR": "Calif\u00f3rnia", "ru": "\u041a\u0430\u043b\u0438\u0444\u043e\u0440\u043d\u0438\u044f", "zh-CN": "\u52a0\u5229\u798f\u5c3c\u4e9a\u5dde" } } ] }
The geolocation information for the host with localized names is in the response.
Details¶
The majority of the sample code is shown below:
# Create the client with DxlClient(config) as client: # Connect to the fabric client.connect() logger.info("Connected to DXL fabric.") # Create and send request request_topic = "/opendxl-maxmind/service/geolocation/host_lookup" req = Request(request_topic) MessageUtils.dict_to_json_payload(req, {"ip":"8.8.8.8"}) res = client.sync_request(req, timeout=30) if res.message_type != Message.MESSAGE_TYPE_ERROR: # Display results res_dict = MessageUtils.json_payload_to_dict(res) print(MessageUtils.dict_to_json(res_dict, pretty_print=True)) else: print("Error invoking service with topic '{0}': {1} ({2})".format( request_topic, res.error_message, res.error_code))
After connecting to the DXL fabric, a request message is created with a topic that targets the "host lookup" method of the MaxMind DXL service.
The next step is to set the payload of the request message. The contents of the payload include the IP address to look up (in this case, 8.8.8.8, a google DNS IP).
The final step is to perform a synchronous request via the DXL fabric. If the response message is not an error its contents are displayed.
