Diese Workerprozesse würden Ihre Anwendung ausführen, sie würden die Hauptberechnungen durchführen, um einen **Request** entgegenzunehmen und eine **Response** zurückzugeben, und sie würden alles, was Sie in Variablen einfügen, in den RAM laden.

### Testen

Öffnen Sie Ihren Browser unter <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.

Sie erhalten die JSON-Response:

```JSON
{"item_id": 5, "q": "somequery"}
```

Damit haben Sie bereits eine API erstellt, welche:

* HTTP-Anfragen auf den _Pfaden_ `/` und `/items/{item_id}` entgegennimmt.

Requestsは非常にシンプルかつ直感的なデザインで使いやすく、適切なデフォルト値を設定しています。しかし同時に、非常に強力でカスタマイズも可能です。

公式サイトで以下のように言われているのは、それが理由です。

> Requestsは今までで最もダウンロードされたPythonパッケージである

使い方はとても簡単です。例えば、`GET`リクエストを実行するには、このように書けば良いです:

```Python
response = requests.get("http://example.com/some/url")
```

対応するFastAPIのパスオペレーションはこのようになります:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

		FreeVersion: fi.TierFreeVersion(),
		Tier:        fi.TransitionTier,
	}

	// etag/md5Sum has already been extracted. We need to
	// remove to avoid it from appearing as part of
	// response headers. e.g, X-Minio-* or X-Amz-*.
	// Tags have also been extracted, we remove that as well.
	objInfo.UserDefined = cleanMetadata(fi.Metadata)

	// All the parts per object.
	objInfo.Parts = fi.Parts

// The s3ChunkedReader returns io.EOF when the final 0-length chunk is read.
//
// NewChunkedReader is not needed by normal applications. The http package
// automatically decodes chunking when reading response bodies.
func newSignV4ChunkedReader(req *http.Request, trailer bool) (io.ReadCloser, APIErrorCode) {
	cred, seedSignature, region, seedDate, errCode := calculateSeedSignature(req, trailer)
	if errCode != ErrNone {

            if (accessResult.getHttpStatusCode() != 200) {
                // invalid page
                if (logger.isDebugEnabled()) {
                    logger.debug("Skipped. The response code is {}.", accessResult.getHttpStatusCode());
                }
                continue;
            }

            final long startTime = systemHelper.getCurrentTimeAsLong();

### Revísalo

Abre tu navegador en <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.

Verás el response JSON como:

```JSON
{"item_id": 5, "q": "somequery"}
```

Ya creaste una API que:

* Recibe requests HTTP en los _paths_ `/` y `/items/{item_id}`.

### Controleer het

Open je browser op <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.

Je zult een JSON response zien:

```JSON
{"item_id": 5, "q": "somequery"}
```

Je hebt een API gemaakt die:

* HTTP verzoeken kan ontvangen op de _paden_ `/` en `/items/{item_id}`.

        @Test
        @DisplayName("Should handle zero sam pointer correctly")
        void testDecodeOutZeroSamPointer() throws NdrException {
            // Given: Message with non-null sam and zero pointer in response
            samr.SamrSamArray samArray = spy(new samr.SamrSamArray());
            samr.SamrEnumerateAliasesInDomain message = new samr.SamrEnumerateAliasesInDomain(mockPolicyHandle, 1, 2, samArray, 3);

Those worker processes would be the ones running your application, they would perform the main computations to receive a **request** and return a **response**, and they would load anything you put in variables in RAM.
