To start working with Shodan you have to get your token first. You can do this at https://www.shodan.io.
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:
2015/09/05 18:50:52 173.194.115.35
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)
}
}
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.
If a method is absent or something doesn't work properly don't hesitate to create an issue.
