Pass action to container.get

[adenhertog]

The IoC integration lacks the request context when resolving instances of a controller. This context is very useful for many IoC integrations that manage their lifecycle on a per-request basis.

As an example, if the consumer wants to bind the request IP address in a child container so that it is available in a request scope, then they'll need to do this work just before the controller gets created. For example:

import { IoCAdapter } from 'routing-controllers'
import { Container } from 'inversify'

class InversifyAdapter implements IocAdapter {
  constructor (
    private readonly container: Container
  ) {
  }

  get<T> (someClass: ClassConstructor<T>, action?: Action): T {
    const childContainer = this.container.createChild()
    childContainer.bind(API_SYMBOLS.RequestorIp).toConstantValuetion.context.ip)
    return childContainer.resolve<T>(someClass)
  } 
}

Here, the resolved controller and all of its dependencies will have access to the IP of the current request scope.

The action has been added as an optional second argument to the get() callback so that it's backwards compatible with existing code.
