To summarize for any encrypted object there exists (at least) three different keys:

- [OEK](#oek): A secret and unique key used to encrypted the object, stored in an encrypted form as part of the object metadata and only loaded to RAM in plaintext during en/decrypting the object.

    // an SSL context for an attacking webserver. It includes both these rogue certificates plus the

你將能進行程式碼補齊，這是在之前你可能曾認為不可能的事。例如，請求 JSON body（可能是巢狀的）中的鍵 `price`。

這樣比較不會輸錯鍵名，不用來回翻看文件，也不用來回滾動尋找你最後使用的 `username` 或者 `user_name`。

### 簡潔 { #short }

FastAPI 為你提供了**預設值**，讓你不必在初期進行繁瑣的配置，一切都可以自動運作。如果你有更具體的需求，則可以進行調整和自定義，

但預設情況下，一切都「直接可用」。

### 驗證 { #validation }

#### 隨機項目 { #a-random-item }

透過 `data.items()` 我們會得到一個包含每個字典項目鍵值對 tuple 的 <dfn title="可以用 for 迴圈遍歷的東西，例如 list、set 等等。">iterable object</dfn>。

我們用 `list(data.items())` 把這個可疊代物件轉成正式的 `list`。

接著用 `random.choice()` 從清單中取得一個「隨機值」，也就是一個 `(id, name)` 的 tuple。可能像是 `("imdb-tt0371724", "The Hitchhiker's Guide to the Galaxy")`。

然後把這個 tuple 的兩個值分別指定給變數 `id` 和 `name`。

因此，即使使用者沒有提供 item ID，仍然會收到一個隨機建議。
