## Was sind „Formulardaten“

HTML-Formulare (`<form></form>`) senden die Daten in einer „speziellen“ Kodierung zum Server, welche sich von JSON unterscheidet.

**FastAPI** stellt sicher, dass diese Daten korrekt ausgelesen werden, statt JSON zu erwarten.

/// note | Technische Details

Но клиент/пользователь этого не увидит. Вместо этого клиент получит сообщение "Internal Server Error" с кодом состояния HTTP `500`.

Так и должно быть, потому что если в вашем *ответе* или где-либо в вашем коде (не в *запросе* клиента) возникает Pydantic `ValidationError`, то это действительно ошибка в вашем коде.

	KeyMarker string

	// When response is truncated (the IsTruncated element value in the response
	// is true), you can use the key name in this field as marker in the subsequent
	// request to get next set of objects. Server lists objects in alphabetical
	// order Note: This element is returned only if you have delimiter request parameter
	// specified. If response does not include the NextMaker and it is truncated,

     *   <li>DELETE - Deletes the specified resource.</li>
     *   <li>HEAD - Same as GET but returns only HTTP headers and no document body.</li>
     *   <li>OPTIONS - Returns the HTTP methods that the server supports.</li>
     *   <li>TRACE - Echoes back the received request, used for debugging.</li>
     *   <li>CONNECT - Converts the request connection to a transparent TCP/IP tunnel.</li>
     * </ul>

// When the `list` query parameter is provided (its value is ignored), the
// server lists all metrics that could be returned for the requested path.
//
// The (repeatable) `buckets` query parameter is a list of bucket names (or it
// could be a comma separated value) to return metrics with a bucket label.

* PostgreSQL
* MySQL
* SQLite
* Oracle
* Microsoft SQL Server, etc.

In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.

Later, for your production application, you might want to use a database server like **PostgreSQL**.
