在我們的範例中，並不是直接用它，而是把它傳給 FastAPI 來使用。

`FastAPI` 應用的 `lifespan` 參數需要一個**非同步內容管理器**，所以我們可以把剛寫好的 `lifespan` 非同步內容管理器傳給它。

## 替代事件（已棄用） { #alternative-events-deprecated }

/// warning

目前建議使用上面所述，透過 `FastAPI` 應用的 `lifespan` 參數來處理 *startup* 與 *shutdown*。如果你提供了 `lifespan` 參數，`startup` 與 `shutdown` 事件處理器將不會被呼叫。要嘛全用 `lifespan`，要嘛全用事件，不能同時混用。

你大概可以直接跳過這一節。

Other HTTP libraries exist that fill that gap allowing extensive customisation including potentially
invalid requests.

Example Limitations

* Does not allow GET with a body.
* Cache is not an interface with alternative implementations.

Get a URL

This program downloads a URL and prints its contents as a string. [Full source][get_example].

OkHttpClient client = new OkHttpClient();

 *   <li>The raw {@code long} values returned by {@code nanoTime} are meaningless and unsafe to use
 *       in any other way than how {@code Stopwatch} uses them.
 *   <li>An alternative source of nanosecond ticks can be substituted, for example for testing or
 *       performance reasons, without affecting most of your code.
 * </ul>
