AdGuard Home's DNS filtering go library
Example use:
[ -z "$GOPATH" ] && export GOPATH=$HOME/go
go get -d github.com/AdguardTeam/AdGuardHome/dnsfilter
Create file filter.go
package main
import (
"github.com/AdguardTeam/AdGuardHome/dnsfilter"
"log"
)
func main() {
filter := dnsfilter.New()
filter.AddRule("||dou*ck.net^")
host := "www.doubleclick.net"
res, err := filter.CheckHost(host)
if err != nil {
// temporary failure
log.Fatalf("Failed to check host %q: %s", host, err)
}
if res.IsFiltered {
log.Printf("Host %s is filtered, reason - %q, matched rule: %q", host, res.Reason, res.Rule)
} else {
log.Printf("Host %s is not filtered, reason - %q", host, res.Reason)
}
}
And then run it:
go run filter.go
You will get:
2000/01/01 00:00:00 Host www.doubleclick.net is filtered, reason - 'FilteredBlackList', matched rule: '||dou*ck.net^'
You can also enable checking against AdGuard's SafeBrowsing:
package main
import (
"github.com/AdguardTeam/AdGuardHome/dnsfilter"
"log"
)
func main() {
filter := dnsfilter.New()
filter.EnableSafeBrowsing()
host := "wmconvirus.narod.ru" // hostname for testing safebrowsing
res, err := filter.CheckHost(host)
if err != nil {
// temporary failure
log.Fatalf("Failed to check host %q: %s", host, err)
}
if res.IsFiltered {
log.Printf("Host %s is filtered, reason - %q, matched rule: %q", host, res.Reason, res.Rule)
} else {
log.Printf("Host %s is not filtered, reason - %q", host, res.Reason)
}
}
