SSE 是一種透過 HTTP 從伺服器向用戶端串流傳送資料的標準。

每個事件都是一個小型文字區塊，包含 `data`、`event`、`id` 和 `retry` 等「欄位」，並以空白行分隔。

看起來像這樣：

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```

SSE 常用於 AI 聊天串流、即時通知、日誌與可觀察性，以及其他由伺服器主動推送更新給用戶端的情境。

/// tip

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