Server-Sent Events (SSE) is a technology used for achieving one-way real-time communication between a client and server. It works by sending event streams from the server to the client in order to push data from the server to the client.<\/p>\n

The working principle of SSE is as follows:<\/p>\n

    \n
  1. Clients connect with the server by creating an EventSource object.<\/li>\n
  2. The server sets the response header Content-Type as text\/event-stream and sends a data message once the connection is established, which marks the beginning of the data stream.<\/li>\n
  3. The server must adhere to a specific format when sending data, which means each data message must start with “data:” and end with two line breaks “\\n\\n”.<\/li>\n
  4. The client handles the data received from the server by listening to the message event.<\/li>\n
  5. The client can update the page content or perform other operations based on the received data.<\/li>\n<\/ol>\n

    Compared to other real-time communication technologies like WebSockets, SSE technology is simpler and easier to use, suitable for scenarios that do not require two-way communication, such as displaying real-time data and notifications.<\/p>\n","protected":false},"excerpt":{"rendered":"
