英文:
Golang, GAE, redirect user?
问题
如何在运行在GAE上的Go中重定向页面请求，以便用户的地址能正确显示，而不需要显示重定向页面？例如，如果用户输入：
www.hello.com/1
我希望我的Go应用程序将用户重定向到：
www.hello.com/one
而不是使用：
fmt.Fprintf(w, "<HEAD><meta HTTP-EQUIV=\"REFRESH\" content=\"0; url=/one\"></HEAD>")
英文:
How can I redirect a page request in Go running on GAE, so that the user's address would display correctly without resorting to displaying a redirection page? For example, if user would type:
www.hello.com/1
I'd want my Go application to redirect the user to:
www.hello.com/one
Without resorting to:
fmt.Fprintf(w, "<HEAD><meta HTTP-EQUIV=\"REFRESH\" content=\"0; url=/one\"></HEAD>")

对于一次性的情况：
func oneHandler(w http.ResponseWriter, r *http.Request) {
http.Redirect(w, r, "/one", http.StatusMovedPermanently)
}
如果这种情况发生几次，你可以创建一个重定向处理程序：
func redirectHandler(path string) func(http.ResponseWriter, *http.Request) {
return func (w http.ResponseWriter, r *http.Request) {
http.Redirect(w, r, path, http.StatusMovedPermanently)
}
}
并像这样使用它：
func init() {
http.HandleFunc("/one", oneHandler)
http.HandleFunc("/1", redirectHandler("/one"))
http.HandleFunc("/two", twoHandler)
http.HandleFunc("/2", redirectHandler("/two"))
//等等。
}
英文:
For a one-off:
func oneHandler(w http.ResponseWriter, r *http.Request) {
http.Redirect(w, r, "/one", http.StatusMovedPermanently)
}
If this happens a few times, you can create a redirect handler instead:
func redirectHandler(path string) func(http.ResponseWriter, *http.Request) {
return func (w http.ResponseWriter, r *http.Request) {
http.Redirect(w, r, path, http.StatusMovedPermanently)
}
}
and use it like this:
func init() {
http.HandleFunc("/one", oneHandler)
http.HandleFunc("/1", redirectHandler("/one"))
http.HandleFunc("/two", twoHandler)
http.HandleFunc("/2", redirectHandler("/two"))
//etc.
}

func handler(rw http.ResponseWriter, ...) {
rw.SetHeader("状态", "302")
rw.SetHeader("位置", "/one")
}
英文:
func handler(rw http.ResponseWriter, ...) {
rw.SetHeader("Status", "302")
rw.SetHeader("Location", "/one")
}
