This tutorial illustrates how to append a CSV file containing User-Agent strings with IsMobile, PlatformName and PlatformVersion properties. The following aspects of the API are covered:
- How to perform a User-Agent match.
- How to reuse resources to perform subsequent matching.
- How to retrieve match results for a specific property.
- How to append a property value to a CSV file.
Code and Explanation
Offline processing example of using 51Degrees device detection. The example
shows how to:
dataFile = settings.V3_WRAPPER_DATABASE
properties = settings.PROPERTIES
cacheSize = settings.CACHE_SIZE
poolSize = settings.POOL_SIZE
provider = fiftyone_degrees_mobile_detector_v3_wrapper.Provider(dataFile, properties, cacheSize, poolSize)
fin = open(inputFile, 'r') fout = open(outputFile, 'w')
fout.write('User-Agent') for name in properties.split(','): fout.write('|' + name) fout.write('\n')
while i < 20 : userAgent = fin.readline().rstrip('\n') fout.write(userAgent) device = provider.getMatch(userAgent) for name in properties.split(','): value = device.getValue(name) fout.write('|' + value) fout.write('\n') i = i + 1This example can be run in any directory, but assumes your settings file contains a valid dataFile location and has the IsMobile property selected.
Offline device detection is frequently required for a variety of reasons such as generating reports. The example is based on an actual support request where several properties had to be added to the CSV file before it could be passed on for another department to use.
This tutorial covered how to use the detector offline to append the first 20 lines of a CSV file with Lite properties: IsMobile , PlatformName and PlatformVersion . Using a Premium or an Enterprise data file gives you access to a far greater number of properties including HardwareVendor , PriceBand , ScreenInchesWidth , IsCrawler and more. A full list of properties and the data file version they are present in can be viewed in the Property Dictionary .
