如果客戶端嘗試在**查詢參數**中發送一些**額外的**資料，他們將會收到一個**錯誤**回應。

例如，如果客戶端嘗試發送一個值為 `plumbus` 的 `tool` 查詢參數，如：

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

他們將收到一個**錯誤**回應，告訴他們查詢參數 `tool` 是不允許的：

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],

## Public Discussions

Please restrain from publicly discussing a potential security vulnerability. 🙊

It's better to discuss privately and try to find a solution first, to limit the potential impact as much as possible.

Thanks for your help!

Wenn der Client beispielsweise versucht, einen `tool` Query-Parameter mit dem Wert `plumbus` zu senden, wie:

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

erhält er eine **Error-Response**, die ihm mitteilt, dass der Query-Parameter `tool` nicht erlaubt ist:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",

For example, if the client tries to send a `tool` query parameter with a value of `plumbus`, like:

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

They will receive an **error** response telling them that the query parameter `tool` is not allowed:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",

var ErrOverread = errors.New("input provided more bytes than specified")

* Sie müssen `File()` nicht als Parameter-Defaultwert verwenden.
* Es wird eine <abbr title="warteschlangenartig">„gespoolte“</abbr> Datei verwendet:
    * Eine Datei, die bis zu einem bestimmten Größen-Limit im Arbeitsspeicher behalten wird, und wenn das Limit überschritten wird, auf der Festplatte gespeichert wird.
* Das bedeutet, es wird für große Dateien wie Bilder, Videos, große Binärdateien, usw. gut funktionieren, ohne den ganzen Arbeitsspeicher aufzubrauchen.
