### Dependency injection

FastAPI'ın inanılmaz derecede kullanımı kolay, fakat inanılmaz derecede güçlü <abbr title='"components", "resources", "services", "providers" olarak da bilinen'><strong>Dependency Injection </strong></abbr> sistemi var.

* Dependencylerin bile dependencies'i olabiliyor, FastAPI bunun  için **graph of "dependency"** yaratıyor.

    private Postbox postbox;

    @Override
    public void setUp() throws Exception {
        super.setUp();
        crawler = new Crawler();

        // Initialize mock components
        searchEngineClient = new SearchEngineClient() {
            // Mock implementation
        };
        crawler.searchEngineClient = searchEngineClient;

        webFsIndexHelper = new WebFsIndexHelper() {

    private UrlFilter urlFilter;
    private StandardCrawlerContainer container;

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        // Initialize container with necessary components
        container = new StandardCrawlerContainer().singleton("dataHelper", MemoryDataHelper.class)
                .singleton("urlFilterService", UrlFilterServiceImpl.class)

所有的這些都是可重複使用的工具和套件，可以輕鬆與你的系統、資料儲存（Data Stores）、關聯式資料庫（RDBMS）以及非關聯式資料庫（NoSQL）等等整合。


### 依賴注入（Dependency Injection）

FastAPI 有一個使用簡單，但是非常強大的<abbr title='也叫做 "components", "resources", "services", "providers"'><strong>依賴注入</strong></abbr>系統。

* 依賴項甚至可以有自己的依賴，從而形成一個層級或**依賴圖**的結構。
* 所有**自動化處理**都由框架完成。
* 依賴項不僅能從請求中提取資料，還能**對 API 的路徑操作進行強化**，並自動生成文檔。
* 即使是依賴項中定義的*路徑操作參數*，也會**自動進行驗證**。

 *   <li>Handle timeouts during SMB operations.</li>
 * </ul>
 *
 * <p>
 * The client uses a {@link SmbAuthenticationHolder} to manage SMB authentication credentials.
 * It also integrates with other Fess Crawler components, such as {@link ContentLengthHelper} and
 * {@link MimeTypeHelper}, to handle content length checks and MIME type detection.
 * </p>
 *
 * <p>
 * The class uses JCIFS properties to configure the SMB connection.
