你可以导入它并通过与 `FastAPI` 类相同的方式创建一个「实例」：

{* ../../docs_src/bigger_applications/app_an_py310/routers/users.py hl[1,3] title["app/routers/users.py"] *}

### 使用 `APIRouter` 的*路径操作* { #path-operations-with-apirouter }

然后你可以使用它来声明*路径操作*。

使用方式与 `FastAPI` 类相同：

{* ../../docs_src/bigger_applications/app_an_py310/routers/users.py hl[6,11,16] title["app/routers/users.py"] *}

你可以将 `APIRouter` 视为一个「迷你 `FastAPI`」类。

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[10:12,23] *}

/// tip | 豆知識

Pydantic が**Rust** 側でシリアライズを行うため、戻り値の型を宣言しない場合に比べて大幅に**高性能**になります。

///

### 非 async の *path operation 関数* { #non-async-path-operation-functions }

通常の `def` 関数（`async` なし）も使用でき、同様に `yield` を使えます。

イベントループをブロックしないよう、FastAPI が正しく実行されるように調整します。

この場合は関数が async ではないため、適切な戻り値の型は `Iterable[Item]` です:

        auth.secureWipePassword();
        assertNull(auth.getPassword());
    }

    /**
     * Test that closed authenticator prevents all sensitive operations
     */
    @Test
    @DisplayName("Test closed authenticator blocks all sensitive operations")
    public void testClosedAuthenticatorBlocking() throws Exception {
        NtlmPasswordAuthenticator auth = new NtlmPasswordAuthenticator("DOMAIN", "user", "BlockedPass123!");

 * <p>This class is GWT-compatible.
 *
 * <h3>Purpose</h3>
 *
 * <p>The main purpose of {@code ListenableFuture} is to help you chain together a graph of
 * asynchronous operations. You can chain them together manually with calls to methods like {@link
 * Futures#transform(ListenableFuture, com.google.common.base.Function, Executor) Futures.transform}
