使用Golang检查网址是否可访问

Question

I want to create a simple script that checks if a certain hostname:port is running. I only want to get a bool response if that URL is live, but I'm not sure if there's a straightforward way of doing it.

Answer 1

If you only want see if a URL is reachable you could use net.DialTimeout. Like this:

timeout := time.Duration(1 * time.Second)
conn, err := net.DialTimeout("tcp","mysyte:myport", timeout)
if err != nil {
    log.Println("Site unreachable, error: ", err)
}
