How to retrieve the final URL destination while using the http package in Go?

问题

大多数网站在请求期间会重定向到另一个URL。例如:http://example.com 可能会重定向到 http://mobile.example.com

有没有办法获取最终的目标URL?在 cURL 中,他们称之为 effective URL

英文:

Most sites redirect to another URL during a request. For example: http://example.com might might redirects to http://mobile.example.com

Is there a way to retrieve the final destination? In case of cURL, they call this the effective URL.

例如,

package main

import (
	"fmt"
	"net/http"
)

func main() {
	getURL := "http://pkgdoc.org/"
	fmt.Println("getURL:", getURL)
	resp, err := http.Get(getURL)
	if err != nil {
		fmt.Println(err)
		return
	}
	finalURL := resp.Request.URL.String()
	fmt.Println("finalURL:", finalURL)
}

输出:

getURL: http://pkgdoc.org/
finalURL: http://godoc.org/
英文:

For example,

package main

import (
	"fmt"
	"net/http"
)

func main() {
	getURL := "http://pkgdoc.org/"
	fmt.Println("getURL:", getURL)
	resp, err := http.Get(getURL)
	if err != nil {
		fmt.Println(err)
		return
	}
	finalURL := resp.Request.URL.String()
	fmt.Println("finalURL:", finalURL)
}

Output:

getURL: http://pkgdoc.org/
finalURL: http://godoc.org/
