I'm having some issues with implementing a slight MVC design with
gorilla/mux.
The layout of the modules is as follows:
main.go-- controllers---- base.controller.go---- example.controller.go--
models---- base.model.go---- example.controller.go
All the files in controllers is in the controllers package, same with models
and
then the main.go is the main package.
Currently I'm just trying to get the Base Controller to be able to be
shared with the main package which is working, although it's throwing some
errors when trying to implement routes. The build is not throwing any
errors, but the routes are not available. If I implement the Walk function
in the Gorilla/Mux documentation to print out all the registered routes for
the mux.Router then it gives me this error:
&{%!!(MISSING)s(*mux.Router=&{ [0xc4200901b0] map[] true false false
false}) %!!(MISSING)s(http.HandlerFunc=0xc8df0)
[%!!(MISSING)s(*mux.routeRegexp=&{/ false false true false 0xc420095360 /
[] []})] %!!(MISSING)s(*mux.routeRegexpGroup=&{ 0xc420016240 []})
%!!(MISSING)s(bool=true) %!!(MISSING)s(bool=false)
%!!(MISSING)s(bool=false) %!!(MISSING)s(bool=false)
%!!(MISSING)s(mux.BuildVarsFunc=)}
The reasoning for the global var V1Router *mux.Router is firstly to access
it in the main package and also to create subrouters in the other
controllers.
I am fairly new to Go, but I'm trying my best to learn the best practices!
Any help would be greatly appreciated!
Example code below:
base.controllers.go
package controllers
import (
"fmt"
"bytes"
"net/http"
"github.com/gorilla/mux")
var V1Router *mux.Router
func init () {
V1Router = mux.NewRouter()
V1Router.StrictSlash(true)
V1Router.HandleFunc("/", BaseHandler) }
// Base route to access the API Documentation.
func BaseHandler (w http.ResponseWriter, r *http.Request) {
fmt.Fprint(w, "Hello, Gophers!")}
main.go
package main
import (
"net/http"
"log"
"github.com/projectrepo/project/models"
"github.com/projectrepo/project/controllers"
"github.com/gorilla/mux")
func main () {
http.Handle("/v1", controllers.V1Router)
if err := http.ListenAndServe(":8000", nil); err != nil {
log.Fatal("Serving error.")
}}
