* `"request"`：在處理請求的路徑操作函式之前啟動相依（與使用 `"function"` 類似），但在回應送回用戶端之後才結束相依。所以，相依函式會在整個**請求**與回應循環的「周圍」執行。

如果未指定且相依使用了 `yield`，則預設 `scope` 為 `"request"`。

### 子相依的 `scope` { #scope-for-sub-dependencies }

當你宣告一個 `scope="request"`（預設值）的相依時，任何子相依也需要有 `"request"` 的 `scope`。

但一個 `scope` 為 `"function"` 的相依，可以擁有 `scope` 為 `"function"` 或 `"request"` 的子相依。

這是因為任何相依都需要能在子相依之前執行其結束程式碼，因為它可能在結束程式碼中仍需要使用那些子相依。
