Here’s a short Go function that converts the URL path into an array; it’s useful if you want to implement REST style queries into a simple application.
func parseComponents(r *http.Request) []string {
//Creates an App Engine Context - required to access App Engine specific services
c := appengine.NewContext(r)
//The URL that the user queried.
path := r.URL.Path
path = strings.TrimSpace(path)
//Log the URL received:
c.Infof("URL: ", path)
//Cut off the leading and trailing forward slashes, if they exist.
//This cuts off the leading forward slash.
if strings.HasPrefix(path, "/") {
path = path[1:]
}
//This cuts off the trailing forward slash.
if strings.HasSuffix(path, "/") {
cut_off_last_char_len := len(path) - 1
path = path[:cut_off_last_char_len]
}
//We need to isolate the individual components of the path.
components := strings.Split(path, "/")
return components
}
