Daten aus Formularen werden, wenn es keine Dateien sind, normalerweise mit dem <abbr title='Media type – Medientyp, Typ des Mediums'>„media type“</abbr> `application/x-www-form-urlencoded` kodiert.

```JSON
{
    "detail": [
        {
            "loc": [
                "path",
                "item_id"
            ],
            "msg": "value is not a valid integer",
            "type": "type_error.integer"
        }
    ]
}
```

вы получите текстовую версию:

```
Validation errors:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

例如，如果客户端尝试发送一个值为 `plumbus` 的 `tool` 查询参数，如：

```http
https://example.com/items/?limit=10&tool=plumbus
```

他们将收到一个**错误**响应，告诉他们查询参数 `tool` 是不允许的：

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus"
        }
    ]
}
```

## 总结

	{err: errObjectTampered, errCode: ErrObjectTampered},

	{err: nil, errCode: ErrNone},
	{err: errors.New("Custom error"), errCode: ErrInternalError}, // Case where err type is unknown.
}

func TestAPIErrCode(t *testing.T) {
	ctx := t.Context()
	for i, testCase := range toAPIErrorTests {
		errCode := toAPIErrorCode(ctx, testCase.err)
		if errCode != testCase.errCode {

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

/// note | Technische Details

Daten aus Formularen werden normalerweise mit dem <abbr title="Medientyp">„media type“</abbr> `application/x-www-form-urlencoded` kodiert.

Wenn das Formular stattdessen Dateien enthält, werden diese mit `multipart/form-data` kodiert. Im nächsten Kapitel erfahren Sie mehr über die Handhabung von Dateien.

L'utiliser dans votre éditeur est ce qui vous montre vraiment les avantages de FastAPI, en voyant le peu de code que vous avez à écrire, toutes les vérifications de type, l'autocomplétion, etc.
