Question

在websockets中将二进制数据作为块发送是可能的。

我使用下面的代码发送二进制数据， 未来f = session.getAsyncRemote（）。sendbinary（bytebuffer）;

这整个传输数据。所以任何人都可以建议我如何以异步方式发送数据或者使用任何java库来实现这个概念。

WebSocket类具有发送碎片帧的方法。以下代码（在README.md中找到）显示了如何发送包含3个分段帧的文本消息（＆＃34;你好吗？＆＃34;）。您可以以类似的方式发送碎片二进制帧。

// The first frame must be either a text frame or a binary frame.
// And its FIN bit must be cleared.
WebSocketFrame firstFrame = WebSocketFrame
    .createTextFrame("How ")
    .setFin(false);

// Subsequent frames must be continuation frames. The FIN bit of
// all continuation frames except the last one must be cleared.
// Note that the FIN bit of frames returned from
// WebSocketFrame.createContinuationFrame() method is cleared,
// so the example below does not clear the FIN bit explicitly.
WebSocketFrame secondFrame = WebSocketFrame
    .createContinuationFrame("are ");

// The last frame must be a continuation frame with the FIN bit
// set. Note that the FIN bit of frames returned from
// WebSocketFrame.createContinuationFrame methods is cleared,
// so the FIN bit of the last frame must be set explicitly.
WebSocketFrame lastFrame = WebSocketFrame
    .createContinuationFrame("you?")
    .setFin(true);

// Send a text message which consists of 3 frames.
ws.sendFrame(firstFrame)
  .sendFrame(secondFrame)
  .sendFrame(lastFrame);

或者，也可以像这样完成上述相同的工作。

// Send a text message which consists of 3 frames.
ws.sendText("How ", false)
  .sendContinuation("are ")
  .sendContinuation("you?", true);
