ipstack.com IPv4 Geolocation Lookup

See more Geolocation Examples

Demonstrates how to lookup Geolocation data for an IPv4 address using the ipstack.com REST API. Lua

local chilkat = require("chilkat")

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

local http = chilkat.Http.new()

-- Lookup an IPv4 address: 149.250.207.170  (this was a randomly chosen address)
local jsonStr = http:quick_get_str("http://api.ipstack.com/149.250.207.170?access_key=YOUR_ACCESS_KEY")
if not http.last_method_success then
    print(http.last_error_text)
    return
end

local json = chilkat.JsonObject.new()
json.emit_compact = false
local success = json:load(jsonStr)

print(json:emit())
