使用自定义标头获取请求失败

Here is my AngularJS code, (it works fine if I remove the header option).

$http.get(env.apiURL()+'/banks', {
    headers: {
        'Authorization': 'Bearer '+localStorageService.get('access_token')
    }
})

Here is the request:

OPTIONS /banks HTTP/1.1
Host: localhost:8080
Connection: keep-alive
Access-Control-Request-Method: GET
Origin: http://localhost:8081
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36
Access-Control-Request-Headers: accept, authorization
Accept: */*
Referer: http://localhost:8081/
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8,vi;q=0.6

And response:

HTTP/1.1 404 Not Found
Access-Control-Allow-Headers: Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization
Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE
Access-Control-Allow-Origin: http://localhost:8081
Content-Type: text/plain; charset=utf-8
Date: Mon, 17 Mar 2014 11:05:20 GMT
Content-Length: 19

I added both Accept and Authorization header but the request still fails?
Does the capitalization (I mean authorization vs Authorization) result in that failure? If yes, how can I make AngularJS stop doing that?

if origin := req.Header.Get("Origin"); origin == "http://localhost:8081" {
    rw.Header().Set("Access-Control-Allow-Origin", origin)
    rw.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")
    rw.Header().Set("Access-Control-Allow-Headers",
        "Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization")
}

Go server routing code:

r := mux.NewRouter()
r.HandleFunc("/banks", RetrieveAllBank).Methods("GET")

http.ListenAndServe(":8080", r)

    OK, the issue because I fotgot to handle the "OPTIONS" request (to make a CORS browser will send a preflight OPTIONS request first and then the 'real' request if accepted by the server).
    I only need to modify my Go server (see the comment):

    func main() {
        r := mux.NewRouter()
        r.HandleFunc("/banks", RetrieveAllBank).Methods("GET")
        http.ListenAndServe(":8080", &MyServer{r})
    }
    
    type MyServer struct {
        r *mux.Router
    }
    
    func (s *IMoneyServer) ServeHTTP(rw http.ResponseWriter, req *http.Request) {
        if origin := req.Header.Get("Origin"); origin == "http://localhost:8081" {
            rw.Header().Set("Access-Control-Allow-Origin", origin)
            rw.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")
            rw.Header().Set("Access-Control-Allow-Headers",
                "Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization")
        }
        // Stop here if its Preflighted OPTIONS request
        if req.Method == "OPTIONS" {
            return
        }
        // Lets Gorilla work
        s.r.ServeHTTP(rw, req)
    }
