I have modify the middleware to the below but it only work if the handler
function "/protected" is in the main function.
I have many handlers and do not want to put all of them in the main.go.
You suggest i define a struct and use member function of the struct, can
you elaborate more about for me or the format.
func ValidateToken(srv *server.Server) func(http.Handler) http.Handler {
return func(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
notAuth := []string{"/oauth2/token", "/credentials"} //List of endpoints
that doesn't require auth
requestPath := r.URL.Path //current request path
//check if request does not need authentication, serve the request if it
doesn't need it
for _, value := range notAuth {
if value == requestPath {
next.ServeHTTP(w, r)
return
}
}
_, err := srv.ValidationBearerToken(r)
if err != nil {
http.Error(w, err.Error(), http.StatusBadRequest)
return
}
next.ServeHTTP(w, r)
})
}
}
