socket.setTimeout(timeout[, callback])

• Returns: <net.Socket> Socket 本身。

当 socket 在 timeout 毫秒不活动之后将其设置为超时状态。默认 net.Socket 没有超时。

当一个闲置的超时被触发，socket 将会收到一个 'timeout' 事件，但连接不会被断开。用户必须手动调用 socket.end() 或 socket.destroy() 来断开连接。

socket.setTimeout(3000);
socket.on('timeout', () => {
  console.log('socket timeout');
  socket.end();
});

如果 timeout 是 0，则存在的闲置超时将会被禁止。

可选的 callback 参数将会被当作一个时间监听器被添加到 'timeout' 事件。

• timeout <number>
• callback <Function>
• Returns: <net.Socket> The socket itself.

Sets the socket to timeout after timeout milliseconds of inactivity on the socket. By default net.Socket do not have a timeout.

When an idle timeout is triggered the socket will receive a 'timeout' event but the connection will not be severed. The user must manually call socket.end() or socket.destroy() to end the connection.

socket.setTimeout(3000);
socket.on('timeout', () => {
  console.log('socket timeout');
  socket.end();
});

If timeout is 0, then the existing idle timeout is disabled.

The optional callback parameter will be added as a one-time listener for the 'timeout' event.
