Go + Angular：加载基本HTML

Question

I'm trying to write an app in Go with Angular. I'm not sure if I got the concept right, but basically I should serve a simple html that loads angular and the app (js) itself and then the rest is handled by ajax requests. What I don't know is how to serve the html file on every non-ajax request on every path? I would like to use Gorilla mux but I couldn't find out how to do that.

Is this even the right direction?

Answer 1

On every request that is not any known url You should send index.html - or whatever is Your base angular app file.

Gorilla/mux has a NotFoundHandler, which is handler for everyting that is not matched by any other routes. You can assignt Your own handler for it like that:

solution with gorilla/mux is:

func main() {
    r := mux.NewRouter()
    r.HandleFunc("/foo", fooHandler)
    r.NotFoundHandler = http.HandlerFunc(notFound)
    http.Handle("/", r)

}

while notFound is:

func notFound(w http.ResponseWriter, r *http.Request) {
    http.ServeFile(w, r, "static/index.html")
}

assuming the Your base file is in static/index.html :).

Now all Your requests that are not any other requests (so, in that setup - not an ajax call defined in routes) will serve index file with url that can be handled by ngRoute or ui-router.
