由于本博主在搞云直播游戏，所以一直在研究java直播弹幕获取
弹幕协议用的是websocket
流程就是:1.连接websocket 2.发送直播间数据和token 3.就能获取到弹幕的推送
以下就是关键代码，懂得自然懂！只要稍微研究一下弹幕 就能看懂我写的啥
源码
@Override
public void onOpen(ServerHandshake arg0) {
// TODO Auto-generated method stub
LOGGER.info("------ MyWebSocket onOpen ------");
//==开头
//byte[] part1=hexToBytes("08c8011ac8010a9801");
//=开头
byte[] part1 = hexToBytes("08c8011adc010aac01");
if (token.lastIndexOf("==") > 0) {
part1 = hexToBytes("08c8011ac8010a9801");
}
//token
byte[] part2 = token.getBytes();
//固定
byte[] part3 = hexToBytes("120b");
//stream_id
byte[] part4 = streamId.getBytes();
//固定
byte[] part5 = hexToBytes("3a1e");
//page_id
byte[] part6 = getPageId().getBytes();
List<byte[]> datas = new LinkedList<>(Arrays.asList(part1, part2, part3, part4, part5, part6));
byte[] resultBytes = new byte[0];
//记录需要复制到目标数组的起始索引
int index = 0;
for (byte[] bytes : datas) {
//复制数组到新数组，并且长度为当前数组长度+bytes的长度
resultBytes = Arrays.copyOf(resultBytes, resultBytes.length + bytes.length);
//将bytes中的内容拼接在结果数组之后
System.arraycopy(bytes, 0, resultBytes, index, bytes.length);
//索引值递增
index += bytes.length;
}
send(resultBytes);
TimerTask task = new TimerTask() {
public void run() {
//20秒心跳包
// String data = byte2Hex(HttpClientUtils.executeByPOST("https://live.kuaishou.com/rest/wd/live/watchingFeed","{\"liveStreamId\":\""+streamId+"\"}").getBytes());
// System.out.println(data);
byte[] heartBeat = hexToBytes("08011a070889aac0da8130");
LOGGER.info("******心跳******");
send(heartBeat);
}
};
Timer timer = new Timer();
long delay = 0;
long intevalPeriod = 20 * 1000;
timer.scheduleAtFixedRate(task, delay, intevalPeriod);
}效果
