## Was sind „Formulardaten“ { #what-is-form-data }

Der Weg, wie HTML-Formulare (`<form></form>`) die Daten zum Server senden, verwendet normalerweise eine „spezielle“ Kodierung für diese Daten. Diese unterscheidet sich von JSON.

         * We *would* just check such functions redundantly, but kotlinc emits its nullness
         * annotations in the form of JetBrains annotations, which have only class retention and
         * thus are invisible at runtime. Thus, we conclude that the parameter types are
         * *non*-nullable, even when they are declared as `Foo?`.

## 什麼是「表單資料」 { #what-is-form-data }

HTML 表單（`<form></form>`）送到伺服器的資料通常使用一種「特殊」編碼，與 JSON 不同。

**FastAPI** 會從正確的位置讀取該資料，而不是當作 JSON。

/// note | 技術細節

表單資料在不包含檔案時，通常使用媒體型別 `application/x-www-form-urlencoded` 編碼。

但當表單包含檔案時，會使用 `multipart/form-data` 編碼。若你使用 `File`，**FastAPI** 會知道要從請求本文的正確部分取得檔案。

Spesifikasyon ayrıca `username` ve `password`’ün form verisi olarak gönderilmesi gerektiğini de söyler (yani burada JSON yok).

### `scope` { #scope }

Spesifikasyon, client’ın "`scope`" adlı başka bir form alanı da gönderebileceğini söyler.

Form alanının adı `scope`’tur (tekil), ama aslında boşluklarla ayrılmış "scope"’lardan oluşan uzun bir string’dir.
