Aquí están las secciones introductorias y los tutoriales para aprender **FastAPI**.

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

ao invés de:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## Recapitulando

            append(rendered ?: "ERROR")

            val valueArguments = annotation.allValueArguments.entries.sortedBy { it.key.asString() }
            printCollectionIfNotEmpty(valueArguments, separator = ", ", prefix = "(", postfix = ")") { (name, value) ->
                append(name.render())
                append(" = ")

            - raw_headers
            - render
            - init_headers
            - headers
            - set_cookie
            - delete_cookie

::: fastapi.responses.ORJSONResponse
    options:
        members:
            - charset
            - status_code
            - media_type
            - body
            - background
            - raw_headers
            - render
            - init_headers

```

이 경우에 **FastAPI**는 본문을 아래 대신에:

```JSON hl_lines="2"
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

아래 처럼 예측할 것 입니다:

```JSON
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

## 정리

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

statt:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## Zusammenfassung

在这种情况下，**FastAPI** 将期望像这样的请求体：

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

而不是：

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## 总结

你可以添加多个请求体参数到*路径操作函数*中，即使一个请求只能有一个请求体。

        KtDiagnosticClassImplementationRenderer.render(path.resolve("KtFirDiagnosticsImpl.kt"), diagnosticList, packageName, emptySet())
        FirDiagnosticToKtDiagnosticConverterRenderer.render(path.resolve("KtFirDataClassConverters.kt"), diagnosticList, packageName, emptySet())

            - render
            - init_headers
            - headers
            - set_cookie
            - delete_cookie
