How to parse URI gracefully using Go?

Question

Here is my kafka connection information in etcd :

kafka://user:[email protected]:9092?mechanism=PLAIN&protocol=SASL_PLAINTEXT

When i get the information string from the etcd, i want to get the username user,password passwd and host 10.10.172.222:9092.

Now how can i parse Kafka connection information gracefully using Golang?

Use net/url library

kafkaUrl := "kafka://[email protected]:9092?mechanism=PLAIN&protocol=SASL_PLAINTEXT" u, err := url.Parse(kafkaUrl) if err != nil { // handle error } user := u.User.Username() pass, isPassSet := u.User.Password() host := u.Host // host or host:port

hostname and port separetely

hostname := u.Hostname() port := u.Port()

Done! Thanks! (by the way, u.Host can get the host or host:port

Actually both it is just string so if port is provided it will be there if not... this is from source code see comment Host string // host or host:port

If you want to get hostname and port separatelly use u.Hostname() and u.Port()
