### Den `RequestValidationError`-Body verwenden

Der `RequestValidationError` enthält den empfangenen `body` mit den ungültigen Daten.

Sie könnten diesen verwenden, während Sie Ihre Anwendung entwickeln, um den Body zu loggen und zu debuggen, ihn zum Benutzer zurückzugeben, usw.

Download a file, print its headers, and print its response body as a string.

The `string()` method on response body is convenient and efficient for small documents. But if the response body is large (greater than 1 MiB), avoid `string()` because it will load the entire document into memory. In that case, prefer to process the body as a stream.
