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`.

### API

#### MockResponse

Mock responses default to an empty response body and a `200` status code.
You can set a custom body with a string, input stream or byte array. Also
add headers with a fluent builder API.

```java
MockResponse response = new MockResponse()
    .addHeader("Content-Type", "application/json; charset=utf-8")

The response will have non-null `cacheResponse` and `networkResponse`. The cacheResponse will be used as the top level
response only if the response code is HTTP/1.1 304 Not Modified.
