golang使用解析标准库从电子邮件获取域

Question

I'm having trouble pulling out the domain for emails. I've tried using variations of

u, _ := url.Parse(email) 

and other parsing from the standard library, but nothing that seems to parse: [e-mail] into separate parts.

I've also tried net.SplitHostPort with no luck.

I don't want to get create a function which gets the len and separate to get substring after @ symbol if possible.

Does anyone have any ideas to do this?

Thanks!

Here's an example I concocted from the golang documentation:

package main

import (
    "fmt"
    "strings"
)

func main() {
    email := "[e-mail]"
    components := strings.Split(email, "@")
    username, domain := components[0], components[1]

    fmt.Printf("Username: %s, Domain: %s
", username, domain)
}
