例如两个步骤
package main
import (
"fmt"
"strings"
)
func main() {
s := strings.Split("127.0.0.1:5432", ":")
ip, port := s[0], s[1]
fmt.Println(ip, port)
}
输出：
127.0.0.1 5432
例如一个步骤
package main
import (

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