A bit controversial opinion, but every DevOps, Cloud engineer needs to know at least how to read application code. As I started my app development journey with Go, also known as Golang, I’ve faced a dozen of issues. To start with, here’s a solution to a general Go’s http package issue: Get "google.com": unsupported protocol scheme "" while trying to send a GET request method to google.com.
Prerequisites
- Go(lang)
- Go http package
Solution
Take the following basic HTTP GET code snippet as an example:
package main
import (
"fmt"
"io/ioutil"
"log"
"net/http"
)
func main() {
resp, err := http.Get("google.com")
if err != nil {
log.Fatal(err)
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
log.Fatal(err)
}
fmt.Println(string(body))
}
If you run this code, without doubt, you’ll get the unsupported protocol scheme "" error.
As for the solution goes, you need to add http:// or https:// in front of google.com. Happy coding!
