Simple reverse proxy in Go (forked from original to use a struct instead of a closure)
package main
import(
"log"
"net/url"
"net/http"
"net/http/httputil"
)
func main() {
remote, err := url.Parse("http://google.com")
if err != nil {
panic(err)
}
proxy := httputil.NewSingleHostReverseProxy(remote)
// use http.Handle instead of http.HandleFunc when your struct implements http.Handler interface
http.Handle("/", &ProxyHandler{proxy})
err = http.ListenAndServe(":8080", nil)
if err != nil {
panic(err)
}
}
type ProxyHandler struct {
p *httputil.ReverseProxy
}
func (ph *ProxyHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
log.Println(r.URL)
w.Header().Set("X-Ben", "Rad")
ph.p.ServeHTTP(w, r)
}
