英文:
Go + Angular ui-router
问题
我是一个新的Gopher，正在尝试使用Go后端为我的AngularJS前端提供服务，并提供API。
这是我目前的代码：
package mainimport ("github.com/gorilla/mux""log""net/http")func main() {rtr := mux.NewRouter()srtr := rtr.PathPrefix("/api").Subrouter()srtr.HandleFunc("/hello", hello).Methods("GET")rtr.PathPrefix("/").Handler(http.FileServer(http.Dir("./static/")))http.Handle("/", rtr)log.Println("Listening...")http.ListenAndServe(":3000", nil)}func hello(w http.ResponseWriter, r *http.Request) {w.Write([]byte("Hello World"))}
一切正常。/api/hello 返回 "Hello World"，如果我访问 /，它将提供我的 index.html。然而，由于我正在尝试使用Angular UI Router，所以我希望我的Go服务器将所有未注册的路由发送到Angular，以便Angular UI Router可以处理它们。
例如：如果我现在访问 /random，它将返回404，因为在 ./static 目录下没有名为 random 的文件。但是我希望Go将该请求转发给Angular，以便ui-router可以处理 /random。

I'm a new Gopher trying to do a Go backend to serve my Angularjs frontend and also serve an API.
This is what I have so far.
package mainimport ("github.com/gorilla/mux""log""net/http")func main() {rtr := mux.NewRouter()srtr := rtr.PathPrefix("/api").Subrouter()srtr.HandleFunc("/hello", hello).Methods("GET")rtr.PathPrefix("/").Handler(http.FileServer(http.Dir("./static/")))http.Handle("/", rtr)log.Println("Listening...")http.ListenAndServe(":3000", nil)}func hello(w http.ResponseWriter, r *http.Request) {w.Write([]byte("Hello World"))}
Everything works fine. /api/hello return "Hello World" and if I go to / it will serve my index.html. However since I'm trying to use angular ui-router so I need my go server to send all non-registered routes to angular so angular ui-router can handle them.
For example: If I go /random right now it will return a 404 since I don't have any file under ./static named random. But what I want is Go to forward that request to Angular so ui-router can handle the /random

在你的路由器中，你应该将index.html提供给所有未定义的其他URL。在mux包中，有一个有用的处理程序：http://www.gorillatoolkit.org/pkg/mux#Router - 查看NotFoundHandler
你可以使用它来处理所有的404错误，并代替提供index.html：
func main() {r := mux.NewRouter()r.HandleFunc("/foo", fooHandler)r.NotFoundHandler = http.HandlerFunc(notFound)http.Handle("/", r)}func notFound(w http.ResponseWriter, r *http.Request) {http.ServeFile(w, r, "static/index.html")}
英文:
In Your router You should serve index.html to all undefined elsewhere URLs. In mux package there is helpful handler:
http://www.gorillatoolkit.org/pkg/mux#Router
- look at NotFoundHandler
You can use it, to handle all 404's and serve index.html instead:
func main() {r := mux.NewRouter()r.HandleFunc("/foo", fooHandler)r.NotFoundHandler = http.HandlerFunc(notFound)http.Handle("/", r)}
and define notFound function:
func notFound(w http.ResponseWriter, r *http.Request) {http.ServeFile(w, r, "static/index.html")}
