Subscribe to Stream Service#

Description#

Subscribe to the stream produced by a function service. The interface uses HTTP Server Sent Events to stream responses to the client, and adds a delimiter \n at the end of each streamed message to control message separation.

It is recommended that after producing all messages in the stream production function, send a stream production end marker \xE0\xFF\xE0\xFF provided by openYuanrong to notify the frontend service to stop receiving message subscriptions for this stream.
