Get Started With IP2Location Scala Module
Dependencies
This library requires IP2Location BIN database to function. You may download the BIN database at
IP2Location LITE BIN Data (Free): https://lite.ip2location.com
IP2Location Commercial BIN Data (Comprehensive): https://www.ip2location.com
IPv4 BIN vs IPv6 BIN
Use the IPv4 BIN file if you just need to query IPv4 addresses.
Use the IPv6 BIN file if you need to query BOTH IPv4 and IPv6 addresses.
Requirements
Intellij IDEA: https://www.jetbrains.com/idea/
Sample Codes
Query geolocation information from BIN database
You can query the geolocation information from the IP2Location BIN database as below:
object IP2LocationTest {
def main(args: Array[String]): Unit = {
val loc = new IP2Location
try {
val ip = "8.8.8.8"
val binfile = "/usr/data/IP-COUNTRY-REGION-CITY-LATITUDE-LONGITUDE-ZIPCODE-TIMEZONE-ISP-DOMAIN-NETSPEED-AREACODE-WEATHER-MOBILE-ELEVATION-USAGETYPE-ADDRESSTYPE-CATEGORY-DISTRICT-ASN.BIN"
val useMMF = true
loc.Open(binfile, useMMF) // initialize with BIN file
// val binpath = Paths.get(binfile)
// val binFileBytes = Files.readAllBytes(binpath)
// loc.Open(binFileBytes) // initialize with byte array
val rec = loc.IPQuery(ip)
if ("OK" == rec.getStatus) System.out.println(rec)
else if ("EMPTY_IP_ADDRESS" == rec.getStatus) System.out.println("IP address cannot be blank.")
else if ("INVALID_IP_ADDRESS" == rec.getStatus) System.out.println("Invalid IP address.")
else if ("MISSING_FILE" == rec.getStatus) System.out.println("Invalid database path.")
else if ("IPV6_NOT_SUPPORTED" == rec.getStatus) System.out.println("This BIN does not contain IPv6 data.")
else System.out.println("Unknown error." + rec.getStatus)
} catch {
case e: Exception =>
System.out.println(e)
e.printStackTrace(System.out)
} finally loc.Close()
}
}
