netcup-dns-api

Implementation for netcup DNS API in Golang.

All DNS API is implemented:

• login
• logout
• infoDnsZone
• infoDnsRecords
• updateDnsZone
• updateDnsRecords

Example Usage

import (
	"log"

	netcup "github.com/aellwein/netcup-dns-api/pkg/v1"
)

func main() {
	client := netcup.NewNetcupDnsClient(12345, "myApiKey", "mySecretApiPassword")

	// Login to the API
	session, err := client.Login()
	if err != nil {
		panic(err)
	}
	defer session.Logout()

	if zone, err := session.InfoDnsZone("myowndomain.org"); err != nil {
		panic(err)
	} else {
		log.Println("DNS zone:", zone)
	}
}

This should give you an output like:

DNS zone: { "DomainName": "myowndomain.org", "Ttl": "...", "Serial": "...", "Refresh": "...", "Retry": "...", "Expire": "...", "DnsSecStatus": false

Error Handling

Usually one would expect an err set only in case of a "hard" or non-recoverable error. This is true for a technical type of error, like failed REST API call or a broken network connection, but the Netcup API may set status to "error" in some cases, where you would rather assume a warning. In such case, the last response from Netcup API is preserved inside the NetcupSession and can be examined:

recs, err := session.InfoDnsRecords("myowndomain.org")
if err != nil {
	if session.LastResponse != nil && 
		sess.LastResponse.Status == string(netcup.StatusError) &&
		sess.LastResponse.StatusCode == 5029 {
			// no records are found in the DNS zone - Netcup indicates an error here.
			println("no error")
		} else {
			return fmt.Errorf("non-recoverable error on InfoDnsRecords: %v", err)
		}
}
