**FastAPI** provides several tools to help you deal with **Security** easily, rapidly, in a standard way, without having to study and learn all the security specifications.

But first, let's check some small concepts.

## In a hurry? { #in-a-hurry }

If you don't care about any of these terms and you just need to add security with authentication based on username and password *right now*, skip to the next chapters.

## OAuth2 { #oauth2 }

}

type latencyStat struct {
	lastmin lastMinuteLatency
	curr    time.Duration
	avg     time.Duration
	peak    time.Duration
	N       int64
}

func (l *latencyStat) update(d time.Duration) {
	l.lastmin.add(d)
	l.N++
	if d > l.peak {
		l.peak = d
	}
	l.curr = l.lastmin.getTotal().avg()
	l.avg = time.Duration((int64(l.avg)*(l.N-1) + int64(l.curr)) / l.N)
}

   同樣地，你可以把 `dataclasses` 與標準型別註記組合使用。
8. 注意這個「路徑操作函式」使用的是一般的 `def` 而非 `async def`。

   一如往常，在 FastAPI 中你可以視需要混用 `def` 與 `async def`。

   如果需要複習何時用哪個，請參考文件中關於 [`async` 與 `await`](../async.md#in-a-hurry) 的章節「In a hurry?」。
9. 這個「路徑操作函式」回傳的不是 dataclass（雖然也可以），而是一個包含內部資料的字典清單。

   FastAPI 會使用 `response_model` 參數（其中包含 dataclass）來轉換回應。

你可以把 `dataclasses` 與其他型別註記以多種方式組合，形成複雜的資料結構。

查看上面程式碼中的註解提示以了解更具體的細節。

    Comme toujours, avec FastAPI vous pouvez combiner `def` et `async def` selon vos besoins.

    Si vous avez besoin d'un rappel sur quand utiliser l'un ou l'autre, consultez la section _« In a hurry? »_ dans la documentation à propos de [`async` et `await`](../async.md#in-a-hurry).

9. Cette *fonction de chemin d'accès* ne renvoie pas des dataclasses (même si elle le pourrait), mais une liste de dictionnaires contenant des données internes.

    // If the host exactly matches, we're done: this connection can carry the address.
    if (address.url.host ==
      this
        .route()
        .address.url.host
    ) {
      return true // This connection is a perfect match.
    }

    // At this point we don't have a hostname match. But we still be able to carry the request if
    // our connection coalescing requirements are met. See also:

    while (true) {
      Waiter pred = null;
      Waiter curr = waitersField;
      if (curr == Waiter.TOMBSTONE) {
        return; // give up if someone is calling complete
      }
      Waiter succ;
      while (curr != null) {
        succ = curr.next;
        if (curr.thread != null) { // we aren't unlinking this node, update pred.
          pred = curr;

- **Consistency** - All languages have consistent access to the same APIs and ergonomics in the DSL.
- **Reduce the size of the Gradle distribution** - We no longer need to carry multiple standard libraries for different languages.

## Decision

We do not introduce new public API methods that include Groovy types in their signatures.
Existing Groovy methods will not be removed immediately.
