Golang : Whois examples
Whois a network utility to find out "who is" the owner behind a domain name. Some owners will display all the private information such as personal home address, mobile/cell phone numbers and while some will choose to protect their privacy. Here are couple of examples on how to implement whois
query in Golang.
Example 1:
package main
import (
"fmt"
"net"
)
func whois(domainName, server string) string {
conn, err := net.Dial("tcp", server+":43")
if err != nil {
fmt.Println("Error")
}
defer conn.Close()
conn.Write([]byte(domainName + "\r\n"))
buf := make([]byte, 1024)
result := []byte{}
for {
numBytes, err := conn.Read(buf)
sbuf := buf[0:numBytes]
result = append(result, sbuf...)
if err != nil {
break
}
}
return string(result)
}
func main() {
result := whois("socketloop.com", "com.whois-servers.net")
fmt.Println(result)
}
Example 2:
package main
import (
"fmt"
"github.com/likexian/whois-go"
)
func main() {
result, err := whois.Whois("socketloop.com")
if err != nil {
fmt.Println(err)
}
fmt.Println(result)
}
