/// tip | Dica

O callback real é apenas um request HTTP.

Ao implementar o callback por conta própria, você pode usar algo como [HTTPX](https://www.python-httpx.org) ou [Requests](https://requests.readthedocs.io/).

///

## Escreva o código de documentação do callback { #write-the-callback-documentation-code }

{* ../../docs_src/server_sent_events/tutorial004_py310.py hl[25,27,31] *}

## POST での SSE { #sse-with-post }

SSE は `GET` だけでなく、**任意の HTTP メソッド**で動作します。

これは、`POST` 上で SSE をストリーミングする [MCP](https://modelcontextprotocol.io) のようなプロトコルで有用です:

## 技術詳細 { #technical-details }

FastAPI は SSE のいくつかのベストプラクティスを標準で実装しています。
