### *Операции пути* с `APIRouter` { #path-operations-with-apirouter }

И затем вы используете его, чтобы объявить ваши *операции пути*.

Используйте его так же, как вы использовали бы класс `FastAPI`:

- **Deferred/Promise**: Async operations

### Index Alias Strategy

Zero-downtime index updates using dual aliases:

```
Index Naming: {baseIndex}.{timestamp}
Example:      my-suggest.20250123120000

Aliases:
├── Search Alias: {baseIndex}          (read operations)
└── Update Alias: {baseIndex}.update   (write operations)
```

### Text Processing Pipeline

```
Input Text

Önce dependency'e odaklanalım.

Bu, bir *path operation function*'ın alabileceği parametrelerin aynısını alabilen basit bir fonksiyondur:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8:9] *}

Bu kadar.

**2 satır**.

Ve tüm *path operation function*'larınızla aynı şekle ve yapıya sahiptir.

Bunu, "decorator" olmadan (yani `@app.get("/some-path")` olmadan) yazılmış bir *path operation function* gibi düşünebilirsiniz.

public class AdminSchedulerAction extends FessAdminAction {

    /**
     * Default constructor.
     */
    public AdminSchedulerAction() {
        super();
    }

    /** Role name for admin scheduler operations */
    public static final String ROLE = "admin-scheduler";

    private static final Logger logger = LogManager.getLogger(AdminSchedulerAction.class);

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[1,23] *}

### Callback *path operation*'ını oluşturun { #create-the-callback-path-operation }

Callback *path operation*'ını oluşturmak için, yukarıda oluşturduğunuz aynı `APIRouter`'ı kullanın.

Normal bir FastAPI *path operation*'ı gibi görünmelidir:

* Muhtemelen alması gereken body'nin bir deklarasyonu olmalı, örn. `body: InvoiceEvent`.

レスポンスモデルを指定するのと同じ方法で、レスポンスに使用されるHTTPステータスコードを以下の*path operations*のいずれかの`status_code`パラメータで宣言することもできます。

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* etc.

{* ../../docs_src/response_status_code/tutorial001_py310.py hl[6] *}

/// note | 備考

`status_code`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation function*のものではありません。

///

 * text during indexing and search operations.
 *
 * <p>Each mapping item consists of one or more input character sequences that are mapped to a single output
 * character sequence. The mapping supports both original values and new values for update operations.</p>

public class CharMappingItem extends DictionaryItem {
    /**

public class AdminSearchlistAction extends FessAdminAction {

    /**
     * Default constructor.
     */
    public AdminSearchlistAction() {
        super();
    }

    /** Role name for admin search list operations */
    public static final String ROLE = "admin-searchlist";
