# 服务器发送事件（SSE） { #server-sent-events-sse }

你可以使用**服务器发送事件**（SSE）向客户端流式发送数据。

这类似于[流式传输 JSON Lines](stream-json-lines.md)，但使用 `text/event-stream` 格式，浏览器原生通过 [`EventSource` API](https://developer.mozilla.org/en-US/docs/Web/API/EventSource) 支持。

## 什么是服务器发送事件？ { #what-are-server-sent-events }

SSE 是一种通过 HTTP 从服务器向客户端流式传输数据的标准。

每个事件是一个带有 `data`、`event`、`id` 和 `retry` 等“字段”的小文本块，以空行分隔。

	"${MINIO[@]}" --address ":$start_port" --read-header-timeout ${srv_hdr_timeout}s --idle-timeout ${srv_idle_timeout}s "${WORK_DIR}/disk/" >"${WORK_DIR}/server1.log" 2>&1 &
	pid=$!
	disown $pid
	sleep 1

	if ! ps -p ${pid} 1>&2 >/dev/null; then
		echo "server1 log:"
		cat "${WORK_DIR}/server1.log"
		echo "FAILED"
		purge "$WORK_DIR"
		exit 1
	fi

	set -e

	logger.FatalIf(deleteBucketMetadataRPC.Register(gm, server.DeleteBucketMetadataHandler), "unable to register handler")

# 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 }

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.

# 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).

# 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).
