How to convert *url.URL to string in GO, Google App Engine
问题
我想获取URL并将其转换为字符串。我有以下代码：
func getURL(w http.ResponseWriter, r *http.Request) {
var url string = r.URL
}
我得到了这个错误：
> "无法将r.URL（类型为*url.URL）转换为字符串类型"
这个代码可以正常工作：
fmt.Fprint(w, r.URL)
但是我想使用它，而不仅仅是打印它。
我应该怎么做？
英文:
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()
}
