发送带有参数的GET请求时获取301状态代码

Question

I have a very simple Go server code setup with mux and when I use curl with GET request params (localhost:8080/suggestions/?locale=en), I get 301 status code (Move permanently). But when there's no get parameters, it's working just fine.

func main() {
router := mux.NewRouter().StrictSlash(true)
router.HandleFunc("/suggestions", handleSuggestions).Methods("GET")
log.Fatal(http.ListenAndServe("localhost:8080", router))
}

Can somebody shed me a light on this.Thanks

Answer 1

That's simply because you registered the path /suggestions (note: there is no trailing slash), and you call the URL localhost:8080/suggestions/?locale=en (there is a trailing slash after /suggestions).

You router detects that there's a registered path which would match the requested path without the trailing slash (based on your Router.StrictSlash() policy), so it sends a redirect which when followed would lead you to a valid, registered path.

Simply use a URL without trailing slash after suggestions:

localhost:8080/suggestions?locale=en
