### Check the responses { #check-the-responses }

Now, if you go to the URL with the port for Uvicorn: <a href="http://127.0.0.1:8000/app" class="external-link" target="_blank">http://127.0.0.1:8000/app</a>, you will see the normal response:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

/// tip

    "info": {
        "title": "FastAPI",
        "version": "0.1.0"
    },
    "paths": {
        "/items/": {
            "get": {
                "responses": {
                    "200": {
                        "description": "Successful Response",
                        "content": {
                            "application/json": {



...
```

#### À quoi sert OpenAPI

De la misma manera, puedes declarar responses de listas de objetos.

Para eso, usa el `typing.List` estándar de Python (o simplemente `list` en Python 3.9 y posteriores):

{* ../../docs_src/extra_models/tutorial004_py39.py hl[18] *}


## Response con `dict` arbitrario { #response-with-arbitrary-dict }

            assertTrue(response.isError());
        }

        @Test
        @DisplayName("Should clear received state")
        void testClearReceived() {
            response.received();
            assertTrue(response.isReceived());

            response.clearReceived();

            assertFalse(response.isReceived());
        }
    }

    @Nested

- `volatile` for status flags
- Synchronized blocks for critical sections
- Thread-local storage via `CrawlingParameterUtil`

**Resource Management**:
- `AutoCloseable` throughout
- `DeferredFileOutputStream` for large responses (temp files for >1MB)
- Connection pooling with limits
- Background temp file deletion via `FileUtil.deleteInBackground()`

**Fault Tolerance**:
- `FaultTolerantClient` wrapper (retry, circuit breaker)
