如何在GO,Google App Engine中将* url.URL转换为字符串

I would like to get the URL and convert it to string. I have to following code:

func getURL(w http.ResponseWriter, r *http.Request) {
    var url string = r.URL
}

I get this:

"cannot convert r.URL (type *url.URL) to type string"

This is working well:

fmt.Fprint(w,r.URL)

But I would like to use it, not just print it.

What should I do?

    The url.URL type has a .String() method.

    Try this.

    func getURL(w http.ResponseWriter, r *http.Request) {
        url := r.URL.String()
    }
    

    http://golang.org/pkg/net/url/#URL.String
