Java Code Example

A quick Java snippet to integrate into the FraudGuard.io API and associated explanation.

This Java code performs the following steps:

1. Sets the FraudGuard.io API credentials (username and password).
2. Defines the IP address to query.
3. Constructs the API endpoint URL.
4. Creates a URL object using the API URL.
5. Opens a connection to the URL using HttpURLConnection.
6. Sets the request method to GET.
7. Sets the basic authentication header using Base64 encoding.
8. Reads the response from the API.
9. Prints the response.
10. Closes the connection.

import java.io.BufferedReader;
import java.io.IOException;

import java.util.Base64;

public class FraudGuardAPIClient {
    public static void main(String[] args) {
        // FraudGuard.io API credentials
        String username = "username";
        String password = "password";

        // IP address to query
        String ipAddress = "8.8.8.8";

        // API endpoint
        String apiUrl = "https://api.fraudguard.io/ip/" + ipAddress;

        try {
            // Create URL object
            URL url = new URL(apiUrl);

            // Create HttpURLConnection object
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();

            // Set request method
            connection.setRequestMethod("GET");

            // Set basic authentication header
            String authString = username + ":" + password;
            String encodedAuthString = Base64.getEncoder().encodeToString(authString.getBytes());
            String authHeaderValue = "Basic " + encodedAuthString;
            connection.setRequestProperty("Authorization", authHeaderValue);

            // Read response
            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String inputLine;
            StringBuilder response = new StringBuilder();

            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();

            // Print response
            System.out.println(response.toString());

            // Close connection
            connection.disconnect();

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Make sure to replace ‘username’ and ‘password’ with your actual API credentials.
