class litestar.response.sse.ServerSentEvent

基底類別：Stream

__init__(content: str | bytes | StreamType[SSEData], *, background: BackgroundTask | BackgroundTasks | None = None, cookies: ResponseCookies | None = None, encoding: str = 'utf-8', headers: ResponseHeaders | None = None, event_type: str | None = None, event_id: int | str | None = None, retry_duration: int | None = None, comment_message: str | None = None, status_code: int | None = None) → None

Initialize the response.

參數:

• content -- Bytes, string or a sync or async iterator or iterable.

• background -- A BackgroundTask instance or BackgroundTasks to execute after the response is finished. Defaults to None.

• cookies -- A list of Cookie instances to be set under the response Set-Cookie header.

• encoding -- The encoding to be used for the response headers.

• headers -- A string keyed dictionary of response headers. Header keys are insensitive.

• status_code -- The response status code. Defaults to 200.

• event_type -- The type of the SSE event. If given, the browser will sent the event to any 'event-listener' declared for it (e.g. via 'addEventListener' in JS).

• event_id -- The event ID. This sets the event source's 'last event id'.

• retry_duration -- Retry duration in milliseconds.

• comment_message -- A comment message. This value is ignored by clients and is used mostly for pinging.
