使用 `with` 區塊可確保在產生器函式（包含 `yield` 的函式）完成後關閉該類檔案物件，也就是在送完回應之後。

在這個範例中因為是存在記憶體的假檔案（`io.BytesIO`），影響不大；但若是實際檔案，務必在處理完成後關閉檔案。

### 檔案與 Async { #files-and-async }

多數情況下，類檔案物件預設不相容於 async/await。

例如，它們沒有 `await file.read()`，也不支援 `async for chunk in file`。

而且在許多情況下，讀取它們會是阻塞操作（可能阻塞事件迴圈），因為資料是從磁碟或網路讀取。

/// info

上面的範例其實是例外，因為 `io.BytesIO` 物件已在記憶體中，讀取不會阻塞任何東西。

但在多數情況下，讀取檔案或類檔案物件會造成阻塞。
