因為這些程式碼分別在應用開始接收請求**之前**與**完成**處理請求之後執行，所以涵蓋了整個應用的**生命週期**（「lifespan」這個詞稍後會很重要 😉）。

這對於為整個應用設定需要**共用**於多個請求的**資源**，以及在之後進行**清理**，非常有用。比如資料庫連線池、或載入一個共用的機器學習模型。

## 使用情境 { #use-case }

先從一個**使用情境**開始，然後看看如何用這個機制解決。

想像你有一些要用來處理請求的**機器學習模型**。🤖

同一組模型會在多個請求間共用，所以不是每個請求或每個使用者各有一個模型。

再想像一下，載入模型**需要一段時間**，因為它必須從**磁碟**讀取大量資料。所以你不想在每個請求都做一次。
