/// info | "说明"

`OAuth2PasswordRequestForm` 与 `OAuth2PasswordBearer` 一样，都不是 FastAPI 的特殊类。

**FastAPI** 把 `OAuth2PasswordBearer` 识别为安全方案。因此，可以通过这种方式把它添加至 OpenAPI。

但 `OAuth2PasswordRequestForm` 只是可以自行编写的类依赖项，也可以直接声明 `Form` 参数。

但由于这种用例很常见，FastAPI 为了简便，就直接提供了对它的支持。

### 使用表单数据

/// tip | "提示"

`OAuth2PasswordRequestForm` 类依赖项的实例没有以空格分隔的长字符串属性 `scope`，但它支持 `scopes` 属性，由已发送的 scope 字符串列表组成。

// IsValid - returns true if input string is a valid
// storage class kind supported.

// UnmarshalText unmarshals storage class from its textual form into
// storageClass structure.
func (sc *StorageClass) UnmarshalText(b []byte) error {
	scStr := string(b)
	if scStr == "" {
		return nil
	}
	s, err := parseStorageClass(scStr)
	if err != nil {

Das war's schon.

**Zwei Zeilen**.

Und sie hat die gleiche Form und Struktur wie alle Ihre *Pfadoperation-Funktionen*.

Sie können sie sich als *Pfadoperation-Funktion* ohne den „Dekorator“ (ohne `@app.get("/some-path")`) vorstellen.

Und sie kann alles zurückgeben, was Sie möchten.
