How to split a string and assign it to variables

Question

In Python it is possible to split a string and assign it to variables:

ip, port = \'127.0.0.1:5432\'.split(\':\')

but in Go it does not see

Answer 1

The IPv6 addresses for fields like RemoteAddr from http.Request are formatted as "[::1]:53343"

So net.SplitHostPort works great:

package main

    import (
        "fmt"
        "net"
    )

    func main() {
        host1, port, err := net.SplitHostPort("127.0.0.1:5432")
        fmt.Println(host1, port, err)

        host2, port, err := net.SplitHostPort("[::1]:2345")
        fmt.Println(host2, port, err)

        host3, port, err := net.SplitHostPort("localhost:1234")
        fmt.Println(host3, port, err)
    }

Output is:

127.0.0.1 5432 
::1 2345 
localhost 1234
