go-shodan

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

Usage

The import path depends on whether you use go modules:

import "github.com/ns3777k/go-shodan/v4/shodan"	// with go modules enabled (GO111MODULE=on or outside GOPATH)
import "github.com/ns3777k/go-shodan/shodan" // with go modules disabled

Simple example of resolving hostnames:

package main

import (
	"log"
	"context"

	"github.com/ns3777k/go-shodan/v4/shodan" // go modules required
)

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:

Streaming example:

package main

import (
	"log"
	"context"

	"github.com/ns3777k/go-shodan/v4/shodan" // go modules required
)

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 actual request data (method, url, body).
