(JavaScript) MaxMind IPv4 Geolocation Lookup

Demonstrates how to lookup Geolocation data for an IPv4 address using the MaxMind GeoIP2 Precision Web Service.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var http = new CkHttp();

http.Login = "MAXMIND_ACCOUNT_ID";
http.Password = "MAXMIND_LICENSE_KEY";
http.Accept = "application/json";

// Lookup an IPv4 address: 149.250.207.170  (this was a randomly chosen address)
var jsonStr = http.QuickGetStr("https://geoip.maxmind.com/geoip/v2.1/country/149.250.207.170");
if (http.LastMethodSuccess == false) {
    console.log(http.LastErrorText);
    return;
}

var json = new CkJsonObject();
json.EmitCompact = false;
success = json.Load(jsonStr);

console.log(json.Emit());
