Esto significaría que **FastAPI** esperaría un cuerpo similar a:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Nuevamente, haciendo solo esa declaración, con **FastAPI** obtienes:

// floating-point values. The real and imaginary parts must be of the same
// size, either float32 or float64 (or assignable to them), and the return
// value will be the corresponding complex type (complex64 for float32,
// complex128 for float64).
func complex(r, i FloatType) ComplexType

// The real built-in function returns the real part of the complex number c.

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

다시 한번, **FastAPI**를 사용하여 해당 선언을 함으로써 얻는 것은:

* 중첩 모델도 편집기 지원(자동완성 등)
* 데이터 변환

    }

    /**
     * Integration test that would require a real cluster environment.
     * Disabled by default - enable with -Dwitness.integration.test=true
     */
    @Test
    void testWitnessEnvironmentConfiguration() throws Exception {
        // Test simulating real witness environment scenarios
        // This test validates integration patterns without requiring real cluster

        // Simulate witness service discovery

        if (cause instanceof ClSQLException) {
            return ((ClSQLException) cause).getSql();
        }
        return "";
    }

    /**
     * Returns the real message.
     *
     * @param cause the underlying exception
     * @return the real message
     */
    protected static String getRealMessage(final SQLException cause) {
        final StringBuilder buf = new StringBuilder(256);

	xForwardedProto  = http.CanonicalHeaderKey("X-Forwarded-Proto")
	xForwardedScheme = http.CanonicalHeaderKey("X-Forwarded-Scheme")
	xRealIP          = http.CanonicalHeaderKey("X-Real-IP")
)

var (
	// RFC7239 defines a new "Forwarded: " header designed to replace the
	// existing use of X-Forwarded-* headers.
	// e.g. Forwarded: for=192.0.2.60;proto=https;by=203.0.113.43

这意味着 **FastAPI** 将期望类似于以下内容的请求体：

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

再一次，仅仅进行这样的声明，你将通过 **FastAPI** 获得：

* 对被嵌入的模型也适用的编辑器支持（自动补全等）
* 数据转换
* 数据校验
