# Veri Akışı { #stream-data }

Veriyi JSON olarak yapılandırabiliyorsanız, [JSON Lines Akışı](../tutorial/stream-json-lines.md) kullanın.

Ancak saf ikili (binary) veri ya da string akıtmak istiyorsanız, bunu şöyle yapabilirsiniz.

/// info | Bilgi

FastAPI 0.134.0 ile eklendi.

///

## Kullanım Senaryoları { #use-cases }

Doğrudan bir AI LLM (Büyük Dil Modeli) servisinin çıktısından saf string'leri akıtmak istediğinizde kullanabilirsiniz.

# 串流資料 { #stream-data }

如果你要串流可用 JSON 結構化的資料，應該[串流 JSON Lines](../tutorial/stream-json-lines.md)。

但如果你想串流純二進位資料或字串，以下是做法。

/// info

已在 FastAPI 0.134.0 新增。

///

## 使用情境 { #use-cases }

當你想串流純字串時可以用這個機制，例如直接轉發來自 AI LLM 服務的輸出。

你也可以用它來串流大型二進位檔案，邊讀邊將每個區塊（chunk）串流出去，而不必一次把整個檔案載入記憶體。

你也可以用同樣方式串流視訊或音訊，甚至可以在處理的同時即時產生並傳送。

## 使用 `yield` 的 `StreamingResponse` { #a-streamingresponse-with-yield }

# Потокова передача даних { #stream-data }

Якщо ви хочете передавати потоком дані, які можна структурувати як JSON, див. [Потокова передача JSON Lines](../tutorial/stream-json-lines.md).

Але якщо ви хочете передавати потоком чисті бінарні дані або строки, ось як це зробити.

/// info | Інформація

Додано у FastAPI 0.134.0.
