# Gelişmiş Python Tipleri { #advanced-python-types }

Python tipleriyle çalışırken işinize yarayabilecek bazı ek fikirler.

## `Union` veya `Optional` Kullanımı { #using-union-or-optional }

Kodunuz herhangi bir nedenle `|` kullanamıyorsa — örneğin bir tip açıklamasında (type annotation) değil de `response_model=` gibi bir yerdeyse — dikey çizgi (`|`) yerine `typing` içindeki `Union`'ı kullanabilirsiniz.

# JSON 相容編碼器 { #json-compatible-encoder }

在某些情況下，你可能需要將某種資料型別（例如 Pydantic 模型）轉換為與 JSON 相容的類型（例如 `dict`、`list` 等）。

例如，當你需要把它儲存在資料庫中。

為此，**FastAPI** 提供了 `jsonable_encoder()` 函式。

## 使用 `jsonable_encoder` { #using-the-jsonable-encoder }

想像你有一個只接受與 JSON 相容資料的資料庫 `fake_db`。

例如，它不接受 `datetime` 物件，因為那與 JSON 不相容。

因此，必須將 `datetime` 物件轉為一個以 [ISO 格式](https://en.wikipedia.org/wiki/ISO_8601) 表示資料的 `str`。

# AssumeRoleWithCustomToken [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

## Introduction

To integrate with custom authentication methods using the [Identity Management Plugin](../iam/identity-management-plugin.md)), MinIO provides an STS API extension called `AssumeRoleWithCustomToken`.

After configuring the plugin, use the generated Role ARN with `AssumeRoleWithCustomToken` to get temporary credentials to access object storage.

  // Returns a shared reference to the wrapped function.
  virtual absl::StatusOr<core::RefCountPtr<FunctionRecord>>
  GetFunctionRecord() = 0;

 private:
  const AbstractFunctionKind kind_;
};

using AbstractFunctionPtr =
    tensorflow::core::IntrusivePtr<tensorflow::AbstractFunction>;

}  // namespace tensorflow

OkHttp TLS
==========

Approachable APIs for using TLS.

A [`HeldCertificate`][held_certificate] is a certificate and its private key. Use the
[builder][held_certificate_builder] to create a self-signed certificate that a test server can use
for HTTPS:

```java
HeldCertificate localhostCertificate = new HeldCertificate.Builder()
    .addSubjectAlternativeName("localhost")
    .build();
```

				}
				// We don't need the input any more.
				//nolint:staticcheck // SA6002 Using pointer would allocate more since we would have to copy slice header before taking a pointer.
				r.bufferPool.Put(in.input)
				in.input = nil
				in.err = d.Err()
				in.dst <- all
			}
		}()
	}
}

// NewPReader - creates new parallel JSON reader using readCloser.
// Should only be used for LINES types.
