## 依賴的錯誤與回傳值 { #dependencies-errors-and-return-values }

你可以使用與平常相同的依賴函式。

### 依賴的需求 { #dependency-requirements }

它們可以宣告請求需求（例如標頭（headers））或其他子依賴：

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[8,13] *}

### 拋出例外 { #raise-exceptions }

這些依賴可以 `raise` 例外，與一般依賴相同：

{* ../../docs_src/dependencies/tutorial006_an_py310.py hl[10,15] *}

### 回傳值 { #return-values }

它們可以回傳值，也可以不回傳；無論如何，回傳值都不會被使用。

- `aws:EpochTime` - This is the date in epoch or Unix time, for use with date/time conditions.
- `aws:PrincipalType` - This value indicates whether the principal is an account (Root credential), user (MinIO user), or assumed role (STS)
- `aws:SecureTransport` - This is a Boolean value that represents whether the request was sent over TLS.
