如果你想串流二進位資料，例如影像或音訊，請參考進階指南：[串流資料](../advanced/stream-data.md)。

## 使用 FastAPI 串流 JSON Lines { #stream-json-lines-with-fastapi }

要用 FastAPI 串流 JSON Lines，你可以在你的*路徑操作函式*中改用 `yield` 逐一產生項目，而不是用 `return`。

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[24] *}

如果你要回傳的每個 JSON 項目型別都是 `Item`（一個 Pydantic 模型），而且該函式是 async，你可以將回傳型別宣告為 `AsyncIterable[Item]`：

            if (searchResponse.getTotalShards() != searchResponse.getSuccessfulShards()) {
                builder.partialResults(true);
            }

            // build highlighting fields
            final String hlPrefix = ComponentUtil.getQueryHelper().getHighlightPrefix();
            for (final SearchHit searchHit : searchHits.getHits()) {

   * the already-requested ones are in service, otherwise we might create more threads than we need.
   *
   * We use [executeCallCount] and [runCallCount] to defend against starting more threads than we
   * need. Both fields are guarded by `this`.
