All dies scheint angesichts dieser einfachen Beispiele möglicherweise nicht so nützlich zu sein.

Aber Sie werden in den Kapiteln über **Sicherheit** sehen, wie nützlich das ist.

Und Sie werden auch sehen, wie viel Code Sie dadurch einsparen.

    // Insert "numInsertions" even numbers into the BF.
    for (int i = 0; i < numInsertions * 2; i += 2) {
      bf.put(Integer.toString(i));
    }
    assertApproximateElementCountGuess(bf, numInsertions);

    // Assert that the BF "might" have all of the even numbers.
    for (int i = 0; i < numInsertions * 2; i += 2) {

import okhttp3.Request

object RequestLine {
  /**
   * Returns the request status line, like "GET / HTTP/1.1". This is exposed to the application by
   * [HttpURLConnection.getHeaderFields], so it needs to be set even if the transport is
   * HTTP/2.

    request: Request,
    proxyType: Proxy.Type,
  ): String =
    buildString {
      append(request.method)

Der Wert des Pfad-Parameters `item_id` wird Ihrer Funktion als das Argument `item_id` übergeben.

Wenn Sie dieses Beispiel ausführen und auf [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo) gehen, sehen Sie als <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr>:

```JSON
{"item_id":"foo"}

Und dann auch, wie man [CORS mittels der `CORSMiddleware`](../tutorial/cors.md) handhabt.

In diesem Abschnitt werden wir sehen, wie man andere Middlewares verwendet.
