how to resolve dependency from api.Container

[shyandsy]

senario

initialize dependencies

1. dependency: config loader
2. dependency: jwt, it will get config information from config loader

use middleware in dependency jwt

problem is How can i resolve dependencies in main() ?

func main() {
	app := iris.New()

	//jwtSvc := feature.NewJWTService("your-secret-key", "myxtea")
	//app.RegisterDependency(func() feature.JWTService {
	//	return jwtSvc
	//})

	feature.ProvideConfigLoader(app)
	feature.ProvideDatabase(app)
	feature.ProvideJWTService(app)

	app.ConfigureContainer(func(api *iris.APIContainer) {

		// I can see my dependencies injected before
		for _, dependency := range api.Container.Dependencies {
			fmt.Println(dependency.String())
                 }
                 ............

it looks there is no such Get ore Resolve method for api.Container

any other solutions?
