I am using a package that has a Router
interface, and I have created my own app-specific Router
interface that wraps the third party package.
Everything is working well, however one of the methods is throwing a compilation error:
controllers/auth.go:52:17: cannot use func literal (type func(router.Router)) as type func(chi.Router) in argument to c.router.Group
This is the interface of the third party package (chi):
type Router interface {
// ...
// Group adds a new inline-Router along the current routing
// path, with a fresh middleware stack for the inline-Router.
Group(fn func(r Router)) Router
// ...
}
This is my wrapper interface:
type Router interface {
chi.Router
// Custom methods...
}
My usage of the Group
function is like so:
type AuthController struct {
router router.Router
// ...
}
func (c *AuthController) SetRoutes() {
c.router.Group(func(r router.Router) {
r.Use(middleware.Anyone)
r.Post("/auth/register", c.Register)
r.Post("/auth/login", c.Authenticate)
r.Post("/auth/token/refresh", c.RefreshToken)
})
c.router.Group(func(r router.Router) {
r.Use(middleware.Authorized)
r.Get("/auth/ping", c.Ping)
r.Post("/auth/logout", c.Logout)
})
}
Why is it screaming at my function callbacks argument type? My wrapper router.Router
implements the chi.Router
interface, so it should work fine shouldn't it? Am I misunderstanding how Go works here?
