Vamos a crear una dependencia `get_current_user`.

¿Recuerdas que las dependencias pueden tener sub-dependencias?

`get_current_user` tendrá una dependencia con el mismo `oauth2_scheme` que creamos antes.

De la misma manera que estábamos haciendo antes en la *path operation* directamente, nuestra nueva dependencia `get_current_user` recibirá un `token` como un `str` de la sub-dependencia `oauth2_scheme`:

{* ../../docs_src/security/tutorial002_an_py310.py hl[25] *}

For example, let's say you have 4 API endpoints (*path operations*):

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

then you could add different permission requirements for each of them just with dependencies and sub-dependencies:

```mermaid
graph TB

 * (yet). Instead, we maintain a list of projects that are excluded from
 * formatting, until we reach a point where we can comfortably format them
 * in one go without too much disruption.
 *
 * Any new sub-projects must not be added to the exclusions list!
 *
 * To perform a reformat, run:
 *
 *     ./gradlew spotlessApply
 *
 * To check the current format, run:
 *
 *     ./gradlew spotlessJavaCheck
 *

It doesn't return a large `str` containing the data in JSON format (as a string). It returns a Python standard data structure (e.g. a `dict`) with values and sub-values that are all compatible with JSON.

/// note

`jsonable_encoder` is actually used by **FastAPI** internally to convert data. But it is useful in many other scenarios.

        public byte revision;
        /**
         * The number of sub-authorities in this SID.
         */
        public byte sub_authority_count;
        /**
         * The identifier authority value (6 bytes).
         */
        public byte[] identifier_authority;
        /**
         * Array of sub-authority values.
         */
        public int[] sub_authority;

        @Override

```python
yield ServerSentEvent(raw_data="plain text line", event="log")
```

## Stream bytes

To stream bytes, declare a `response_class=` of `StreamingResponse` or a sub-class, and use `yield` to return the data.

```python
from fastapi import FastAPI
from fastapi.responses import StreamingResponse
from app.utils import read_image

app = FastAPI()

{* ../../docs_src/behind_a_proxy/tutorial004_py310.py hl[9] *}

y entonces no lo incluirá en el esquema de OpenAPI.

## Montando una sub-aplicación { #mounting-a-sub-application }

Si necesitas montar una sub-aplicación (como se describe en [Aplicaciones secundarias - Monturas](sub-applications.md)) mientras usas un proxy con `root_path`, puedes hacerlo normalmente, como esperarías.
