# 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。

新增于 FastAPI 0.135.0。

## 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。

				if len(offlineEndpoints) > 0 {
