Use as `response_class=EventSourceResponse` on a *path operation* that uses `yield` to enable Server Sent Events (SSE) responses. Works with **any HTTP method** (`GET`, `POST`, etc.), which makes it compatible with protocols like MCP that stream SSE over `POST`. The actual encoding logic lives in the FastAPI routing layer. This class serves mainly as a marker and sets the correct `Content-Type`. ztext/event-streamN)__name__ __module__ __qualname____doc__ media_typeJ/var/www/html/serviGia/entorno/lib/python3.12/site-packages/fastapi/sse.pyrrs %JrrvN field_namereturnc8|d|vsd|vrtd|d|S)N  zSSE 'z' must be a single line) ValueError)r r!s r_check_single_liner'$s-}$!)tqy5 ,CDEE Hrct|dS)Nr)r'r s r_check_event_single_liner**s a ))rc<|d|vr tdt|dS)Nz)SSE 'id' must not contain null charactersr)r&r'r)s r_check_id_validr-.s&}DEE a &&rcTeZdZUdZdZeeedfed<dZ ee dzedfed<dZ ee dze e edfed<dZee dze eed fed <dZeedzed ed fed<dZee dzedfed<edddZy)ServerSentEventatRepresents a single Server-Sent Event. When `yield`ed from a *path operation function* that uses `response_class=EventSourceResponse`, each `ServerSentEvent` is encoded into the [SSE wire format](https://html.spec.whatwg.org/multipage/server-sent-events.html#parsing-an-event-stream) (`text/event-stream`). If you yield a plain object (dict, Pydantic model, etc.) instead, it is automatically JSON-encoded and sent as the `data:` field. All `data` values **including plain strings** are JSON-serialized. For example, `data="hello"` produces `data: "hello"` on the wire (with quotes). NaB The event payload. Can be any JSON-serializable value: a Pydantic model, dict, list, string, number, etc. It is **always** serialized to JSON: strings are quoted (`"hello"` becomes `data: "hello"` on the wire). Mutually exclusive with `raw_data`. raQ Raw string to send as the `data:` field **without** JSON encoding. Use this when you need to send pre-formatted text, HTML fragments, CSV lines, or any non-JSON payload. The string is placed directly into the `data:` field as-is. Mutually exclusive with `data`. raw_dataz Optional event type name. Maps to `addEventListener(event, ...)` on the browser. When omitted, the browser dispatches on the generic `message` event. Must be a single line. rz Optional event ID. The browser sends this value back as the `Last-Event-ID` header on automatic reconnection. **Must be a single line** and must not contain null (`\0`) characters. rr)gez Optional reconnection time in **milliseconds**. Tells the browser how long to wait before reconnecting after the connection is lost. Must be a non-negative integer. rz Optional comment line(s). Comment lines start with `:` in the SSE wire format and are ignored by `EventSource` clients.
