What's Covered
This tutorial illustrates how to return a match for a Device Id. It shows how to first get the Device Id from a match, then get a match for that Device Id and return the value of the IsMobile property. This can be useful to look at devices that have already been matched at a previous date.
Code and Explanation
Match with device id example of using 51Degrees device detection. The example shows how to:
-
Instantiate the 51Degrees device detection provider.
provider = FiftyOneDegreesPatternV3.NewProvider(dataFile)
-
Produce a match for a single device id
match = provider.GetMatchForDeviceId(deviceId)
-
Extract the value of the IsMobile property
match.GetValue("IsMobile")
package main import ( "fmt" "./src/pattern" ) // Location of data file. var dataFile = "../data/51Degrees-LiteV3.2.dat" // Which properties to retrieve var properties = []string{"IsMobile", "PlatformName", "PlatformVersion"} // Provides access to device detection functions. var provider = FiftyOneDegreesPatternV3.NewProvider(dataFile) // User-Agent string of an iPhone mobile device. var mobileUserAgent = "Mozilla/5.0 (iPhone; CPU iPhone OS 7_1 like Mac OS X) " + "AppleWebKit/537.51.2 (KHTML, like Gecko) 'Version/7.0 Mobile/11D167 " + "Safari/9537.53" // User-Agent string of Firefox Web browser version 41 on desktop. var desktopUserAgent = "Mozilla/5.0 (Windows NT 6.3; WOW64; rv:41.0) " + "Gecko/20100101 Firefox/41.0" // User-Agent string of a MediaHub device. var mediaHubUserAgent = "Mozilla/5.0 (Linux; Android 4.4.2; X7 Quad Core " + "Build/KOT49H) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 " + "Chrome/30.0.0.0 Safari/537.36" func main() { fmt.Println("Starting Match With Device Id Example.") // Fetches the device id for a mobile User-Agent. var match = provider.GetMatch(mobileUserAgent) var mobileDeviceId = match.GetDeviceId() // Fetches the device id for a desktop User-Agent. match = provider.GetMatch(desktopUserAgent) var desktopDeviceId = match.GetDeviceId() // Fetches the device id for a MediaHub User-Agent. match = provider.GetMatch(mediaHubUserAgent) var mediaHubDeviceId = match.GetDeviceId() // Carries out a match with a mobile device id. fmt.Println("\nMobile Device Id: ", mobileDeviceId) match = provider.GetMatchForDeviceId(mobileDeviceId) fmt.Println(" IsMobile: ", match.GetValue("IsMobile")) // Carries out a match with a desktop device id. fmt.Println("\nDesktop Device Id: ", desktopDeviceId) match = provider.GetMatchForDeviceId(desktopDeviceId) fmt.Println(" IsMobile: ", match.GetValue("IsMobile")) // Carries out a match with a MediaHub device id. fmt.Println("\nMediaHub Device Id: ", mediaHubDeviceId) match = provider.GetMatchForDeviceId(mediaHubDeviceId) fmt.Println(" IsMobile: ", match.GetValue("IsMobile")) }
Summary
In this tutorial you have seen how to use the detector to retrieve the IsMobile property for a pre-defined Device ID 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 files they exist in please see the Property Dictionary .
