若你需要兩個彼此獨立的 FastAPI 應用程式，各自擁有獨立的 OpenAPI 與文件 UI，你可以有一個主應用，並「掛載」一個（或多個）子應用程式。

## 掛載一個 **FastAPI** 應用程式 { #mounting-a-fastapi-application }

「掛載」是指在某個特定路徑下加入一個完全「獨立」的應用程式，之後該應用程式會負責處理該路徑底下的一切，使用該子應用程式中宣告的*路徑操作（path operation）*。

### 頂層應用程式 { #top-level-application }

先建立主（頂層）**FastAPI** 應用程式以及它的*路徑操作*：

### 子應用程式 { #sub-application }

///

/// warning | 注意

*path operation*で複数の`Form`パラメータを宣言することができますが、JSONとして受け取ることを期待している`Body`フィールドを宣言することはできません。なぜなら、リクエストは`application/x-www-form-urlencoded`の代わりに`application/json`を使ってボディをエンコードするからです。

これは **FastAPI**の制限ではなく、HTTPプロトコルの一部です。

- Temporary credentials do not need to be stored with the application but are generated dynamically and provided to the application when requested. When (or even before) the temporary credentials expire, the application can request new credentials.

Following are advantages for using temporary credentials:

- Eliminates the need to embed long-term credentials with an application.
