## Simple y Poderoso { #simple-and-powerful }

Aunque el sistema de inyección de dependencias jerárquico es muy simple de definir y usar, sigue siendo muy poderoso.

Puedes definir dependencias que a su vez pueden definir dependencias ellas mismas.

## Simple and Powerful { #simple-and-powerful }

Although the hierarchical dependency injection system is very simple to define and use, it's still very powerful.

You can define dependencies that in turn can define dependencies themselves.

Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.

The authentication flow is similar to that of OpenID, however the token is "opaque" to MinIO - it is simply sent to the plugin for verification. CAVEAT: There is no console UI integration for this method of authentication and it is intended primarily for machine authentication.

    I target = newTargetIterator();
    for (int i = 0; i < stimuli.length; i++) {
      try {
        stimuli[i].executeAndCompare(reference, target);
        verify(reference.getElements());
      } catch (AssertionError cause) {
        throw new AssertionError("failed with stimuli " + subListCopy(stimuli, i + 1), cause);
      }
    }
  }

Logra algo algo similar a lo que se puede hacer con Flask-apispec.

Tiene un sistema de inyección de dependencias integrado, inspirado por Angular 2. Requiere pre-registrar los "inyectables" (como todos los otros sistemas de inyección de dependencias que conozco), por lo que añade a la verbosidad y repetición de código.

The `TestClient` is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, and luckily, we can use it directly to test the API.

## Example { #example }

For a simple example, let's consider a file structure similar to the one described in [Bigger Applications](../tutorial/bigger-applications.md){.internal-link target=_blank} and [Testing](../tutorial/testing.md){.internal-link target=_blank}:

Download [`certgen`](https://github.com/minio/certgen/releases/latest) for your specific operating system and platform.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh
./certgen -host "10.10.0.3,10.10.0.4,10.10.0.5"
```

A response similar to this one should be displayed:

2018/11/21 10:16:18 wrote private.key
```
