因此,我正在使用net / http包。我正在获取一个我肯定知道要重定向的URL。在到达最终网址之前,它甚至可能重定向了几次。重定向在后台自动处理。
有没有一种简单的方法来确定最终的URL是什么,而没有涉及在http.Client对象上设置CheckRedirect字段的棘手的解决方法?
我想我应该提一提我想出了一种解决方法,但这有点of脚,因为它涉及使用全局变量并在自定义http.Client上设置CheckRedirect字段。
必须有一种更清洁的方式来做到这一点。我希望这样的事情:
package main import ( "fmt" "log" "net/http" ) func main() { // Try to GET some URL that redirects. Could be 5 or 6 unseen redirections here. resp, err := http.Get("http://some-server.com/a/url/that/redirects.html") if err != nil { log.Fatalf("http.Get => %v", err.Error()) } // Find out what URL we ended up at finalURL := magicFunctionThatTellsMeTheFinalURL(resp) fmt.Printf("The URL you ended up at is: %v", finalURL) }
package main import ( "fmt" "log" "net/http" ) func main() { resp, err := http.Get("http://stackoverflow.com/q/16784419/727643") if err != nil { log.Fatalf("http.Get => %v", err.Error()) } // Your magic function. The Request in the Response is the last URL the // client tried to access. finalURL := resp.Request.URL.String() fmt.Printf("The URL you ended up at is: %v\n", finalURL) }
输出:
The URL you ended up at is: http://stackoverflow.com/questions/16784419/in-golang-how-to-determine-the-final-url-after-a-series-of-redirects
