`Query`, `Path`, und andere Klassen, die Sie später sehen werden, sind Unterklassen einer gemeinsamen `Param`-Klasse.

Alle von ihnen teilen die gleichen Parameter für zusätzliche Validierung und Metadaten, die Sie gesehen haben.

///

/// note | Technische Details

Wenn Sie `Query`, `Path` und andere von `fastapi` importieren, sind sie tatsächlich Funktionen.

Buna genellikle **webhook** denir.

## Webhook adımları { #webhooks-steps }

Süreç genellikle şöyledir: Kodunuzda göndereceğiniz mesajın ne olduğunu, yani request'in **body**'sini **siz tanımlarsınız**.

Ayrıca uygulamanızın bu request'leri veya event'leri hangi **anlarda** göndereceğini de bir şekilde tanımlarsınız.

 *       .compare(this.anInt, that.anInt)
 *       .compare(this.anEnum, that.anEnum, Ordering.natural().nullsLast())
 *       .result();
 * }
 * }
 *
 * <p>The value of this expression will have the same sign as the <i>first nonzero</i> comparison
 * result in the chain, or will be zero if every comparison result was zero.
 *
 * <p><b>Note:</b> {@code ComparisonChain} instances are <b>immutable</b>. For this utility to work

          url = server.url("/"),
          body =
            object : ForwardingRequestBody(transferKind.newRequestBody("def")) {
              override fun writeTo(sink: BufferedSink) {
                sinkReference.set(sink)
                super.writeTo(sink)
              }
            },
        ),
      )
    assertThat(readAscii(response.body.byteStream(), Int.MAX_VALUE))
      .isEqualTo("abc")

			expectedSignStr:  "",
			expectedErrCode:  ErrMissingFields,
		},
		// Test case - 3.
		// SignElement with missing "SignatureTag",ErrMissingSignTag expected.
		{
			inputSignElement: "Sign=",
			expectedSignStr:  "",
			expectedErrCode:  ErrMissingSignTag,
		},
		// Test case - 4.
		// Test case with valid inputs.
		{
			inputSignElement: "Signature=abcd",
			expectedSignStr:  "abcd",

	biggerBufMin = 32 << 10

	// This is the maximum size of bigger buffers.
	biggerBufMax = maxBufferSize

	// If there is a queue, merge up to this many messages.
	maxMergeMessages = 50

	// clientPingInterval will ping the remote handler every 15 seconds.
	// Clients disconnect when we exceed 2 intervals.
	clientPingInterval = 15 * time.Second

	// Deadline for single (non-streaming) requests to complete.

Aquí tienes algunas ideas adicionales que podrían ser útiles al trabajar con tipos de Python.

## Usar `Union` u `Optional` { #using-union-or-optional }

Si por alguna razón tu código no puede usar `|`, por ejemplo si no está en una anotación de tipos sino en algo como `response_model=`, en lugar de usar la barra vertical (`|`) puedes usar `Union` de `typing`.

Por ejemplo, podrías declarar que algo podría ser un `str` o `None`:

      @Override public long contentLength() {
        return -1; // We don't know the compressed length in advance!
      }

      @Override public void writeTo(BufferedSink sink) throws IOException {
        BufferedSink gzipSink = Okio.buffer(new GzipSink(sink));
        body.writeTo(gzipSink);
        gzipSink.close();
      }
    };
  }
}
```

### Rewriting Responses

    private BigDecimalToDoubleRounder() {}

    @Override
    double roundToDoubleArbitrarily(BigDecimal bigDecimal) {
      return bigDecimal.doubleValue();
    }

    @Override
    int sign(BigDecimal bigDecimal) {
      return bigDecimal.signum();
    }

    @Override
    BigDecimal toX(double d, RoundingMode mode) {
      return new BigDecimal(d);
    }

    @Override

Stellen Sie sicher, dass Sie prüfen, ob die **Vorteile** für Ihren Anwendungsfall die **Nachteile** ausgleichen. 🤓
