# Server-Sent Events (SSE) { #server-sent-events-sse }

You can stream data to the client using **Server-Sent Events** (SSE).

This is similar to [Stream JSON Lines](stream-json-lines.md), but uses the `text/event-stream` format, which is supported natively by browsers with the [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).

# Server-Sent Events (SSE) { #server-sent-events-sse }

Puedes enviar datos en streaming al cliente usando **Server-Sent Events** (SSE).

Esto es similar a [Stream JSON Lines](stream-json-lines.md), pero usa el formato `text/event-stream`, que los navegadores soportan de forma nativa con la [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).

- Improved scheduling performance when many nodes, and prefilter returns 1-2 nodes (e.g. daemonset)
  
  For developers of out-of-tree PostFilter plugins, note that the semantics of NodeToStatusMap are changing: A node with an absent value in the NodeToStatusMap should be interpreted as having an UnschedulableAndUnresolvable status ([#125307](https://github.com/kubernetes/kubernetes/pull/125307), [@gabesaba](https://github.com/gabesaba)) [SIG Scheduling]

# Server-Sent Events（SSE） { #server-sent-events-sse }

你可以使用 Server-Sent Events（SSE）把資料串流傳送給用戶端。

這與[串流 JSON Lines](stream-json-lines.md)類似，但使用瀏覽器原生支援、透過 [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource) 的 `text/event-stream` 格式。

## 什麼是 Server-Sent Events？ { #what-are-server-sent-events }

SSE 是一種透過 HTTP 從伺服器向用戶端串流傳送資料的標準。

# Server-Sent Events (SSE) { #server-sent-events-sse }

İstemciye veri akışını **Server-Sent Events** (SSE) ile sağlayabilirsiniz.

Bu, [JSON Lines Akışı](stream-json-lines.md) ile benzerdir ancak tarayıcılar tarafından yerel olarak desteklenen [`EventSource` API'si](https://developer.mozilla.org/en-US/docs/Web/API/EventSource) ile `text/event-stream` formatını kullanır.

FastAPI 0.135.0'da eklendi.

///

# События, отправляемые сервером (SSE) { #server-sent-events-sse }

Вы можете передавать данные потоком клиенту, используя Server-Sent Events (SSE).

Это похоже на [Стриминг JSON Lines](stream-json-lines.md), но использует формат `text/event-stream`, который нативно поддерживается браузерами через [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).

# 서버 전송 이벤트(SSE) { #server-sent-events-sse }

브라우저 클라이언트로 데이터를 스트리밍하려면 **Server-Sent Events**(SSE)를 사용할 수 있습니다.

이는 [JSON Lines 스트리밍](stream-json-lines.md)과 비슷하지만, 브라우저가 기본적으로 [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource)를 통해 지원하는 `text/event-stream` 형식을 사용합니다.

FastAPI 0.135.0에 추가되었습니다.

## Server-Sent Events란 { #what-are-server-sent-events }

# Server-Sent Events (SSE) { #server-sent-events-sse }

**Server-Sent Events** (SSE) を使うと、クライアントへデータをストリーミングできます。

これは[JSON Lines のストリーミング](stream-json-lines.md)に似ていますが、`text/event-stream` フォーマットを使用します。これはブラウザがネイティブに [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource) でサポートしています。
