enforce strict null checks.

 *  New: The response message is now non-null. This is the "Not Found" in the
    status line "HTTP 404 Not Found". If you are building responses
    programmatically (with `new Response.Builder()`) you must now always supply
    a message. An empty string `""` is permitted. This value was never null on
    responses returned by OkHttp itself, and it was an old mistake to permit

Sie können auch `from starlette.requests import Request` und `from starlette.responses import JSONResponse` verwenden.

**FastAPI** bietet dieselben `starlette.responses` auch via `fastapi.responses` an, als Annehmlichkeit für Sie, den Entwickler. Die meisten verfügbaren Responses kommen aber direkt von Starlette. Das Gleiche gilt für `Request`.

Incluye los `tags`, `parameters`, `requestBody`, `responses`, etc.

Este esquema de OpenAPI específico de *path operation* normalmente se genera automáticamente por **FastAPI**, pero también puedes extenderlo.

/// tip | Consejo

Este es un punto de extensión de bajo nivel.

/// note | Technical Details

You could also use `from starlette.requests import Request` and `from starlette.responses import JSONResponse`.

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette. The same with `Request`.

///

Notice that the *path operations* define the models they use for request payload and response payload, using the models `Item` and `ResponseMessage`.

### API Docs { #api-docs }

If you go to `/docs`, you will see that it has the **schemas** for the data to be sent in requests and received in responses:

## Rewriting Responses

If transparent compression was used, OkHttp will drop the corresponding response headers `Content-Encoding` and `Content-Length` because they don’t apply to the decompressed response body.

If a conditional GET was successful, responses from the network and cache are merged as directed by the spec.

## Follow-up Requests

        if (this.ptype == 2 || this.ptype == 3) { /* Response or Fault */
            this.alloc_hint = buf.dec_ndr_long();
            buf.dec_ndr_short(); /* context id */
            buf.dec_ndr_short(); /* cancel count */
        }
        if (this.ptype == 3 || this.ptype == 13) { /* Fault */
            this.result = buf.dec_ndr_long();
        } else { /* Bind_ack or Response */
            decode_out(buf);
        }
    }

    Note over client,operation: Response is already sent, can't change it anymore
    opt Tasks
        operation -->> tasks: Send background tasks
    end
    opt Raise other exception
        tasks -->> tasks: Handle exceptions in the background task code
    end
```

/// info

Only **one response** will be sent to the client. It might be one of the error responses or it will be the response from the *path operation*.
