<p>I've been using gorilla/mux for my routing needs. But I noticed one problem, when I nest multiple Subrouters it doesn't work.</p>
<p>Here is the example:</p>
<pre><code>func main() {
r := mux.NewRouter().StrictSlash(true)
api := r.Path("/api").Subrouter()
u := api.Path("/user").Subrouter()
u.Methods("GET").HandlerFunc(UserHandler)
http.ListenAndServe(":8080", r)
}
</code></pre>
<p>I wanted to use this approach so I can delegate populating the router to some other package, for example user.Populate(api)</p>
<p>However this doesn't seem to work. It works only if I use single Subrouter in the chain.</p>
<p>Any ideas?</p>

<p>When creating path-based subrouter, you have to obtain it with PathPrefix instead of Path.</p>
<pre><code>r.PathPrefix("/api").Subrouter()
</code></pre>
<p>Use r.Path("/api") only when attaching handlers to that endpoint.</p></pre>dreadyfire: <pre><p>Would you mind posting this question/answer over on stackoverflow.com too?</p></pre>kortemy: <pre><p>I did. <a href="http://stackoverflow.com/questions/29575972/nesting-subrouters-in-gorilla" rel="nofollow">http://stackoverflow.com/questions/29575972/nesting-subrouters-in-gorilla</a></p></pre>dreadyfire: <pre><p>Thank you very much</p></pre>
