Mais de cette façon nous pouvons nous concentrer sur le fonctionnement du système d’**injection de dépendances**.

### Créer une dépendance, ou « dependable » { #create-a-dependency-or-dependable }

Concentrons-nous d’abord sur la dépendance.

C’est simplement une fonction qui peut prendre tous les mêmes paramètres qu’une fonction de chemin d’accès peut prendre :

        for (int i = 0; i < dataLength; i++) {
            testData[i] = (byte) (i & 0xFF);
        }
        System.arraycopy(testData, 0, buffer, dataOffsetFromHeader, dataLength);

        // Use reflection to set headerStart
        Field headerStartField = ServerMessageBlock2.class.getDeclaredField("headerStart");
        headerStartField.setAccessible(true);
        headerStartField.set(response, headerStart);

You can mount WSGI applications as you saw with [Sub Applications - Mounts](sub-applications.md), [Behind a Proxy](behind-a-proxy.md).

For that, you can use the `WSGIMiddleware` and use it to wrap your WSGI application, for example, Flask, Django, etc.

## Using `WSGIMiddleware` { #using-wsgimiddleware }

/// info

This requires installing `a2wsgi` for example with `pip install a2wsgi`.

 * [system DNS service][SYSTEM], which is the default. Some applications may provide their own
 * implementation to use a different DNS server, to prefer IPv6 addresses, to prefer IPv4 addresses,
 * or to force a specific known IP address.
 *
 * Implementations of this interface must be safe for concurrent use.

# Streaming

## Stream JSON Lines

To stream JSON Lines, declare the return type and use `yield` to return the data.

```python
@app.get("/items/stream")
async def stream_items() -> AsyncIterable[Item]:
    for item in items:
        yield item
```

## Server-Sent Events (SSE)

To stream Server-Sent Events, use `response_class=EventSourceResponse` and `yield` items from the endpoint.

                name = platform.name,
                dirs = platform.children.takeIf { it.isNotEmpty() }?.map { it.name } ?: listOf(platform.name),
                uses = platform.uses.map { use -> allPlatforms.single { it.id == use }.name },
            )
        }
        outputFile.get().asFile.writeText(Gson().toJson(data))
    }
