## 使用 FastAPI 串流 SSE { #stream-sse-with-fastapi }

要在 FastAPI 中串流 SSE，請在你的路徑操作函式（path operation function）中使用 `yield`，並設定 `response_class=EventSourceResponse`。

從 `fastapi.sse` 匯入 `EventSourceResponse`：

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

每個 `yield` 的項目都會以 JSON 編碼並放在 SSE 事件的 `data:` 欄位中送出。

如果你把回傳型別宣告為 `AsyncIterable[Item]`，FastAPI 會用它來透過 Pydantic 進行**驗證**、**文件化**與**序列化**。

        errorResponse.message(testMessage);
        errorResponse.status(Status.BAD_REQUEST);
        ApiResult result = errorResponse.result();

        assertNotNull(result);
        // Cannot directly access protected fields, just verify the result is not null
    }

    // Test configuration for JSON response
    @Test
    public void test_configurationSettings() {
        ComponentUtil.setFessConfig(new FessConfig.SimpleImpl() {

		WriteMerges:  stats[5],
		WriteSectors: stats[6],
		WriteTicks:   stats[7],
		CurrentIOs:   stats[8],
		TotalTicks:   stats[9],
		ReqTicks:     stats[10],
	}
	// as per the doc, only 11 fields are guaranteed
	// only set if available
	if len(stats) > 14 {
		iostats.DiscardIOs = stats[11]
		iostats.DiscardMerges = stats[12]
		iostats.DiscardSectors = stats[13]
		iostats.DiscardTicks = stats[14]
	}

        String message = "forced downgrade detected";

        // Act
        SMBProtocolDowngradeException ex = new SMBProtocolDowngradeException(message, cause);

        // Assert - fields preserved
        assertSame(cause, ex.getCause());
        assertEquals(message, ex.getMessage());

        // Since message is explicitly provided, constructor should not need to call methods on cause

## FastAPI로 SSE 스트리밍 { #stream-sse-with-fastapi }

FastAPI에서 SSE를 스트리밍하려면, 경로 처리 함수에서 `yield`를 사용하고 `response_class=EventSourceResponse`를 설정하세요.

`EventSourceResponse`는 `fastapi.sse`에서 임포트합니다:

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

각 `yield`된 항목은 JSON으로 인코딩되어 SSE 이벤트의 `data:` 필드로 전송됩니다.
