What's Covered

This tutorial illustrates the basic use of the 51Degrees API. It will show you how to create a provider, how to create a dataset and how to obtain a value for the IsMobile property.

Code and Explanation

Getting started example of using 51Degrees trie device detection. The example shows how to:

  1. Import settings from the 51Degrees settings file 

    												
dataFile = settings.V3_WRAPPER_TRIE_DATABASE
properties = settings.PROPERTIES

  • Instantiate the 51Degrees trie device detection provider with these properties 

    									
provider = fiftyone_degrees_mobile_detector_v3_trie_wrapper.Provider(
	dataFile,
	properties)
  • Produce a match for a single HTTP User-Agent header 

    									
match = provider.getMatch(userAgent)

  • Extract the value of the IsMobile property 

    									
match.getValues('IsMobile')
    This example can be run in any directory, but assumes your settings file contains a valid dataFile location and has the IsMobile property selected. By comparing this to the gettingstarted.py example which uses the pattern method, you can see the differences are the module name, the data file, and it does not use a cache or pool, so these do not need to be set.

    • Summary

    In this tutorial you have seen how to use the detector to retrieve the IsMobile property for a pre-defined User-Agent string. The example can easily be modified to retrieve the value of any other property. Premium and Enterprise data files provide considerably more properties such as IsCrawler , PriceBand , HardwareVendor and ScreenInchesWidth . For a full list of properties and the data file versions they exist in please see the Property Dictionary .
