`OAuth2PasswordBearer` 會讓 **FastAPI** 知道它是一個 security scheme，因此會以那種方式加入 OpenAPI。

但 `OAuth2PasswordRequestForm` 只是你也可以自己撰寫的一個類別型依賴，或是你也可以直接宣告 `Form` 參數。

只是因為這是很常見的用例，所以 **FastAPI** 直接內建提供，讓事情更簡單。

///

### 使用表單資料 { #use-the-form-data }

/// tip

`OAuth2PasswordRequestForm` 這個依賴類別的實例不會有以空白分隔長字串的 `scope` 屬性，而是會有一個 `scopes` 屬性，裡面是各個 scope 的實際字串清單。

本示例沒有使用 `scopes`，但如果你需要，功能已經在那裡了。

* PR bir şekilde basitleştirilebiliyorsa bunu isteyebilirsiniz. Ancak çok didik didik etmeye gerek yok; konuya göre birçok öznel bakış açısı olabilir (benim de olacaktır 🙈). Bu yüzden temel noktalara odaklanmak daha iyi.

### Testler { #tests }

    /** NTLM authentication type identifier. */
    public static final String NTLM = "NTLM";

    /** Form-based authentication type identifier. */
    public static final String FORM = "FORM";

    /** Samba authentication type identifier. */
    public static final String SAMBA = "SAMBA";

    /** FTP authentication type identifier. */

          System.out.println(response.body().string());
        }
      }
    ```

### Posting form parameters ([.kt][PostFormKotlin], [.java][PostFormJava])

Use `FormBody.Builder` to build a request body that works like an HTML `<form>` tag. Names and values will be encoded using an HTML-compatible form URL encoding.
