Ви можете транслювати дані клієнту за допомогою **Server-Sent Events** (SSE).

Це подібно до [Потік JSON Lines](stream-json-lines.md), але використовує формат `text/event-stream`, який нативно підтримується браузерами через [API `EventSource`](https://developer.mozilla.org/en-US/docs/Web/API/EventSource).

# 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。

}

// client to talk to bootstrap NEndpoints.
type bootstrapRESTClient struct {
	gridConn *grid.Connection
}

// Verify function verifies the server config.

#### `server`
The server component of Elasticsearch that contains all of the modules and
plugins. Right now things like the high level rest client depend on the server
but we'd like to fix that in the future.

#### `test`
Our test framework and test fixtures. We use the test framework for testing the
server, the plugins, and modules, and pretty much everything else. We publish
