离线行为

缓冲事件​

¥Buffered events

默认情况下，在 Socket 未连接时触发的任何事件都将被缓冲，直到重新连接为止。

¥By default, any event emitted while the Socket is not connected will be buffered until reconnection.

虽然在大多数情况下（当重新连接延迟很短时）很有用，但它可能会导致连接恢复时出现大量事件。

¥While useful in most cases (when the reconnection delay is short), it could result in a huge spike of events when the connection is restored.

有多种解决方案可以防止这种行为，具体取决于你的用例：

¥There are several solutions to prevent this behavior, depending on your use case:

  • 使用 Socket 实例的 connected 属性

    ¥use the connected attribute of the Socket instance

if (socket.connected) {
  socket.emit( /* ... */ );
} else {
  // ...
}
socket.volatile.emit( /* ... */ );
