# 生成 SDK { #generating-sdks }

因为 **FastAPI** 基于 **OpenAPI** 规范，它的 API 可以用许多工具都能理解的标准格式来描述。

这让你可以轻松生成最新的**文档**、多语言的客户端库（<abbr title="Software Development Kits - 软件开发工具包">**SDKs**</abbr>），以及与代码保持同步的**测试**或**自动化工作流**。

本指南将带你为 FastAPI 后端生成一个 **TypeScript SDK**。

## 开源 SDK 生成器 { #open-source-sdk-generators }

一个功能多样的选择是 [OpenAPI Generator](https://openapi-generator.tech/)，它支持**多种编程语言**，可以根据你的 OpenAPI 规范生成 SDK。

#### Union { #union }

Puedes declarar que una variable puede ser cualquiera de **varios tipos**, por ejemplo, un `int` o un `str`.

Para definirlo usas la <dfn title='también llamado "operador OR a nivel de bits", pero ese significado no es relevante aquí'>barra vertical (`|`)</dfn> para separar ambos tipos.

Esto se llama una "unión", porque la variable puede ser cualquiera en la unión de esos dos conjuntos de tipos.

   * @param arrays zero or more {@code float} arrays
   * @return a single array containing all the values from the source arrays, in order
   * @throws IllegalArgumentException if the total number of elements in {@code arrays} does not fit
   *     in an {@code int}
   */
  public static float[] concat(float[]... arrays) {
    long length = 0;
    for (float[] array : arrays) {
      length += array.length;
    }

            // Since FLAGS2_RESOLVE_PATHS_IN_DFS is 0x1000, when cast to byte it becomes 0
            // Therefore the method will always return false unless flags has all 0x00 bits set
            // This test verifies actual behavior
            testBlock.setFlags((byte) 0x00);
            assertFalse(testBlock.isResolveInDfs());

	// Date and time when the file was last modified, if Deleted
	// is 'true' this value represents when while was deleted.
	ModTime time.Time `msg:"mt"`

	// Total file size.
	Size int64 `msg:"sz"`

	// File mode bits.
	Mode uint32 `msg:"m"`

	// WrittenByVersion is the unix time stamp of the MinIO
	// version that created this version of the object.
	WrittenByVersion uint64 `msg:"wv"`

	// File metadata

        src[srcIndex + 16] = 0x00; // hex code
        src[srcIndex + 17] = (byte) 0xFE; // All flags except one: 11111110
        // Bit 7: group (1)
        // Bits 6-5: owner node type (11 = 3)
        // Bit 4: being deleted (1)
        // Bit 3: in conflict (1)
        // Bit 2: active (1)
        // Bit 1: permanent (1)

        // MAC address

# 產生 SDK { #generating-sdks }

由於 **FastAPI** 建立在 **OpenAPI** 規格之上，其 API 能以許多工具都能理解的標準格式來描述。

這讓你能輕鬆產生最新的**文件**、多語言的用戶端程式庫（<abbr title="Software Development Kits - 軟體開發套件">**SDKs**</abbr>），以及與程式碼保持同步的**測試**或**自動化工作流程**。

在本指南中，你將學會如何為你的 FastAPI 後端產生 **TypeScript SDK**。

## 開源 SDK 產生器 { #open-source-sdk-generators }

其中一個相當萬用的選擇是 [OpenAPI Generator](https://openapi-generator.tech/)，它支援**多種程式語言**，並能從你的 OpenAPI 規格產生 SDK。

   * @param arrays zero or more {@code double} arrays
   * @return a single array containing all the values from the source arrays, in order
   * @throws IllegalArgumentException if the total number of elements in {@code arrays} does not fit
   *     in an {@code int}
   */
  public static double[] concat(double[]... arrays) {
    long length = 0;
    for (double[] array : arrays) {
      length += array.length;
    }

# SDK 생성하기 { #generating-sdks }

**FastAPI**는 **OpenAPI** 사양을 기반으로 하므로, FastAPI의 API는 많은 도구가 이해할 수 있는 표준 형식으로 설명할 수 있습니다.

덕분에 여러 언어용 클라이언트 라이브러리(<abbr title="Software Development Kits - 소프트웨어 개발 키트">**SDKs**</abbr>), 최신 **문서**, 그리고 코드와 동기화된 **테스트** 또는 **자동화 워크플로**를 쉽게 생성할 수 있습니다.

이 가이드에서는 FastAPI 백엔드용 **TypeScript SDK**를 생성하는 방법을 배웁니다.

// 3 the component model -> interfaces for the plugin

// The plugin manager should load up a directory structure of plugins.
// - a plugin per directory where the plugin is present with its deps
// - a plugin that has its dependencies packaged up with it
// - implement filters and create a test where a plugin fails if the right classes are not filtered
