go-shodan

To start working with Shodan you have to get your token first. You can do this at https://www.shodan.io.

Installation

Download the package:

go get "gopkg.in/ns3777k/go-shodan.v3"

That's it. You're ready to roll :-) v3 is the latest release and thus has some breaking changing (take a look at changelog).

Older releases can be found under v1 and v2 tags.

master-branch is considered to be unstable.

Usage

Simple example of resolving hostnames:

package main

import (
	"log"
	"context"

	"gopkg.in/ns3777k/go-shodan.v3/shodan"
)

func main() {
	client := shodan.NewEnvClient(nil)
	dns, err := client.GetDNSResolve(context.Background(), []string{"google.com", "ya.ru"})

	if err != nil {
		log.Panic(err)
	} else {
		log.Println(dns["google.com"])
	}
}

Output for above:

2015/09/05 18:50:52 173.194.115.35

Streaming example:

package main

import (
	"log"
	"context"

	"gopkg.in/ns3777k/go-shodan.v3/shodan"
)

func main() {
	client := shodan.NewEnvClient(nil)
	ch := make(chan *shodan.HostData)
	err := client.GetBannersByASN(context.Background(), []string{"3303", "32475"}, ch)
	if err != nil {
		panic(err)
	}

	for {
		banner, ok := <-ch

		if !ok {
			log.Println("channel was closed")
			break
		}

		log.Println(banner.Product)
	}
}

Tips and tricks

Every method accepts context in the first argument so you can easily cancel any request.

You can also use SetDebug(true) to see the curl version of your requests.
