Hi,
I am new to Go and programming in general but I’m trying to write a small program to check URL’s to see if they are valid. My code generates an error and stops once it gets to a URL where there is no response. Could someone please advise how I can print the error and continue?
The error that I get is
Exception has occurred: panic
“runtime error: invalid memory address or nil pointer dereference”

var url = []string{

}
func checkUrl(url []string) {
for _, s := range url {
resp, err := http.Get(s)
fmt.Println(resp)
if err != nil {
fmt.Println(err)
}
resp.Body.Close()
}
}
func main() {
checkUrl(url)
