I am newer to Go and Google App Engine and I'm trying to build a simple middleware API that queries an external API.
Because I am using the standard env on Google App Engine I have to use urlfetch to create a http request. With Google's documentation, I can't figure out how to add in headers to my GET request - though the documentation clearly states I can add in headers.
https://cloud.google.com/appengine/docs/standard/go/outbound-requests
This is the code I am trying to modify to include a custom request header:
import (
"fmt"
"net/http"
"google.golang.org/appengine"
"google.golang.org/appengine/urlfetch"
)
func handler(w http.ResponseWriter, r *http.Request) {
ctx := appengine.NewContext(r)
client := urlfetch.Client(ctx)
resp, err := client.Get("https://www.google.com/")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
fmt.Fprintf(w, "HTTP GET returned status %v", resp.Status)
}
Any help would be much appreciated.
