There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (
    APIKeyCookie,
    APIKeyHeader,
    APIKeyQuery,

# 子應用程式 - 掛載 { #sub-applications-mounts }

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*：

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[3, 6:8] *}

### 子應用程式 { #sub-application }

            }
            param("credentialsStorageType", "credentialsJSON")
            // Disallow Web UI changes to TeamCity settings
            param("teamcity.ui.settings.readOnly", "true")
            // Avoid rebuilding same revision if it's already built on another branch
            param("teamcity.vcsTrigger.runBuildOnSameRevisionInEveryBranch", "false")
