如何在golang中创建绝对路径http重定向

Question

I was reading the source code goto, and I found the code below in goto/talk/0/main.go:

http.Redirect(w, r, url, http.StatusFound)

According to the context, url was an absolute path, and an absolute path redirect was expected. But as the golang/http/redirect mentioned:

Redirect replies to the request with a redirect to url, which may be a path relative to the request path.

It results as a relative path redirect. I don't know if http.Redirect did an absolute path redirect before, but it doesn't nowadays.

So how can I make an absolute path redirect in golang? I searched the Internet, but found nothing,can anyone help me? Thanks in advance.

Answer 1

I finally found that to perform an absolute path redirect, the url must be a complete url, such as http://www.stackoverflow.com or https://github.com, but not www.stackoverflow.com.
