WebSocket 1001 Going Away vs 1003 Unsupported Data
Both WebSocket 1001 (Going Away) and 1003 (Unsupported Data) belong to the WebSocket Close Codes category. 1001 indicates that an endpoint is going away, such as a server shutting down or a browser navigating away from the page. The connection must be closed. Meanwhile, 1003 means that an endpoint received a type of data it cannot accept. For example, a text-only endpoint received a binary message, or vice versa.
Deskripsi
An endpoint is going away, such as a server shutting down or a browser navigating away from the page. The connection must be closed.
Ketika Anda Melihatnya
The server is shutting down for maintenance, or the user navigated away from the page or closed the browser tab while a WebSocket was open.
Cara Memperbaiki
Implement automatic reconnection logic with exponential backoff in your client. If the server is restarting, the client should retry after a short delay.
Deskripsi
An endpoint received a type of data it cannot accept. For example, a text-only endpoint received a binary message, or vice versa.
Ketika Anda Melihatnya
The client sent a binary frame to a server that only handles text, or a text frame to a binary-only endpoint. The receiver does not know how to process this data type.
Cara Memperbaiki
Verify the message type (text vs binary) matches what the server expects. Update your client to send the correct opcode for the data format.
