Neste exemplo, ele converteria o modelo Pydantic em um `dict`, e o `datetime` em um `str`.

对此你可以使用`jsonable_encoder`。

它接收一个对象，比如Pydantic模型，并会返回一个JSON兼容的版本：

//// tab | Python 3.10+

```Python hl_lines="4  21"
{!> ../../docs_src/encoder/tutorial001_py310.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="5  22"
{!> ../../docs_src/encoder/tutorial001.py!}
```

在这个例子中，它将Pydantic模型转换为`dict`，并将`datetime`转换为`str`。

since Go source text is Unicode characters encoded in UTF-8, multiple
UTF-8-encoded bytes may represent a single integer value.  For
instance, the literal <code>'a'</code> holds a single byte representing
a literal <code>a</code>, Unicode U+0061, value <code>0x61</code>, while
<code>'ä'</code> holds two bytes (<code>0xc3</code> <code>0xa4</code>) representing

같은 방식으로 이 데이터베이스는 Pydantic 모델(속성이 있는 객체)을 받지 않고, `dict` 만을 받습니다.

이를 위해 `jsonable_encoder` 를 사용할 수 있습니다.

Pydantic 모델과 같은 객체를 받고 JSON 호환 가능한 버전으로 반환합니다:

```Python hl_lines="5  22"
{!../../docs_src/encoder/tutorial001.py!}
```

이 예시는 Pydantic 모델을 `dict`로, `datetime` 형식을 `str`로 변환합니다.

# Encoders - `jsonable_encoder`

		return err
	}

	if dexp.Days <= 0 {
		return errInvalidDaysDelMarkerExpiration
	}

	*de = DelMarkerExpiration(dexp)
	return nil
}

// MarshalXML encodes a DelMarkerExpiration value into an XML element
func (de DelMarkerExpiration) MarshalXML(enc *xml.Encoder, start xml.StartElement) error {
	if de.Empty() {
		return nil
	}

	type delMarkerExpiration DelMarkerExpiration

3. The EGLDisplay and EGLConfig types from the EGL API.

These types are uintptr on the Go side because they would otherwise
confuse the Go garbage collector; they are sometimes not really
pointers but data structures encoded in a pointer type. All operations
on these types must happen in C. The proper constant to initialize an
empty such reference is 0, not nil.

These special cases were introduced in Go 1.10. For auto-updating code

    <glob pattern="*.p7c"/>

    <glob pattern="*.p7s"/>

      <!-- PEM encoded -->
      <match value="-----BEGIN PKCS7" type="string" offset="0"/>
      <!-- DER encoded, sequence+length, object=pkcs7-signedData -->
      <match value="0x3080" offset="0">
         <match value="0x06092a864886f70d0107FFa0" type="string"
