## IDs de operação personalizados e nomes de métodos melhores { #custom-operation-ids-and-better-method-names }

Você pode **modificar** a maneira como esses IDs de operação são **gerados** para torná-los mais simples e ter **nomes de método mais simples** nos clientes.

    /**
     * Test: Retry logic correctly enforces maxRetryCount
     * Verifies that with maxRetryCount=5, the operation is tried exactly 6 times (initial + 5 retries)
     */
    @Test
    public void testRetryLogicMaxRetryCount() throws Exception {
        fesenClient.setMaxRetryCount(5);

        Throwable rootCause = new IllegalArgumentException("Invalid argument");
        Throwable intermediateCause = new RuntimeException("Processing failed", rootCause);
        String message = "Plugin operation failed";
        PluginException exception = new PluginException(message, intermediateCause);

        assertNotNull(exception);
        assertEquals(message, exception.getMessage());

Da Pydantic es auf der **Rust**-Seite serialisiert, erhalten Sie eine deutlich höhere **Leistung**, als wenn Sie keinen Rückgabetyp deklarieren.

///

### Nicht-async-*Pfadoperation-Funktionen* { #non-async-path-operation-functions }

Sie können auch normale `def`-Funktionen (ohne `async`) verwenden und `yield` genauso einsetzen.

FastAPI stellt sicher, dass sie korrekt ausgeführt wird, sodass sie die Event Loop nicht blockiert.

Como o Pydantic fará a serialização no lado em **Rust**, você terá um desempenho muito maior do que se não declarar um tipo de retorno.

///

### *Funções de operação de rota* não assíncronas { #non-async-path-operation-functions }

Você também pode usar funções `def` normais (sem `async`) e usar `yield` da mesma forma.

O FastAPI garantirá a execução correta para não bloquear o event loop.

# 回應狀態碼 { #response-status-code }

就像你可以指定回應模型一樣，你也可以在任一個「路徑操作（path operation）」的參數 `status_code` 中宣告回應所使用的 HTTP 狀態碼：

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

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

/// note | 注意

請注意，`status_code` 是「裝飾器（decorator）」方法（`get`、`post` 等等）的參數，而不是你的「路徑操作函式」的參數，就像所有的參數與 body 一樣。

///

參數 `status_code` 接受一個數字作為 HTTP 狀態碼。
