How to get URL in http.Request

Question

I built an HTTP server. I am using the code below to get the request URL, but it does not get full URL.

func Handler(w http.ResponseWriter, r *http.Request) {       fmt.Printf("Req: %s %s", r.URL.Host, r.URL.Path) } 

I only get "Req: / " and "Req: /favicon.ico".

I want to get full client request URL as "1.2.3.4/" or "1.2.3.4/favicon.ico".

Thanks.

Answer 1

From the documentation of net/http package:

type Request struct {    ...    // The host on which the URL is sought.    // Per RFC 2616, this is either the value of the Host: header    // or the host name given in the URL itself.    // It may be of the form "host:port".    Host string    ... } 

Modified version of your code:

func Handler(w http.ResponseWriter, r *http.Request) {     fmt.Printf("Req: %s %s\n", r.Host, r.URL.Path)  } 

Example output:

Req: localhost:8888 /

I use req.URL.RequestURI() to get the full url.

From net/http/requests.go :

// RequestURI is the unmodified Request-URI of the // Request-Line (RFC 2616, Section 5.1) as sent by the client // to a server. Usually the URL field should be used instead. // It is an error to set this field in an HTTP client request. RequestURI string
