How can I determine the currency code for the IP address location using Scala?

To determine the currency code for an IP address using IP2Location.io in Scala, you can use the IP2Location.io API to retrieve geolocation and related data.

  1. We'll assume that you have already installed an IDE like IntelliJ that supports Scala and we won't cover that here. You will also need a paid subscription to the Plus plan or higher. Subscribe now!
  2. In your IDE, create a new Scala project. Then, add Gson into your project.
  3. Save the below code into a file called Test.scala on your computer.
    Scala 
    
import com.google.gson.*
import java.net.URI
import java.net.http.{HttpClient, HttpRequest, HttpResponse}

@main def Test(): Unit = {
  try {
    val key = "YOUR_API_KEY"
    val ip = "8.8.8.8"

    val url = "https://api.ip2location.io/?format=json&key=" + key + "&ip=" + ip
    val request = HttpRequest.newBuilder.uri(new URI(url)).GET.build
    val client = HttpClient.newHttpClient
    val response = client.sendAsync(request, HttpResponse.BodyHandlers.ofString).join()
    val statusCode = response.statusCode()
    if (statusCode == 200) {
      val rawJSON = response.body()
      val myObj = JsonParser.parseString(rawJSON).getAsJsonObject
      if (myObj.has("country")) {
        System.out.println("The currency code for IP " + ip + " is " + myObj.getAsJsonObject("country").getAsJsonObject("currency").get("code").getAsString + ".")
      } else {
        throw Exception("ERROR: The currency code field requires a paid subscription to the Plus plan or higher.")
      }
    } else if (statusCode == 400 || statusCode == 401) {
      val rawJSON = response.body()
      if (rawJSON.contains("error_message")) {
        throw Exception("ERROR: " + JsonParser.parseString(rawJSON).getAsJsonObject.getAsJsonObject("error")
          .get("error_message").getAsString
        )
      }
      throw Exception(rawJSON)
    } else {
      throw Exception(response.body())
    }
  } catch {
    case e: Exception => System.out.println(e)
  }
}
  4. In the IDE, run the Test.scala file.

This script will output the currency code of specified IP address. Make sure to replace 8.8.8.8 with the IP address you want and replace YOUR_API_KEY to your own API key.
