科大讯飞 Websockets API 的问题？

尝试调用科大讯飞的实时语音流式转写接口：https://www.xfyun.cn/doc/asr/voicedictation/API.html

xunfei = XunFei(APPID='...', APISecret='...', AudioFile=r'test.pcm')
url = xunfei.create_url()
async def hello():
    async with websockets.connect(url) as websocket:
        cc = xunfei.read_audio()
        print("数据：" + json.dumps(cc))
        await websocket.send(str(json.dumps(cc)))
        while True:
            message = await websocket.recv()
            print(f"收到消息: {json.loads(message)}")
if __name__ == "__main__":
    asyncio.run(hello())

但老是报错

Traceback (most recent call last):
  File "/var/www/QBA/config/voice.py", line 135, in <module>
    asyncio.run(hello())
  File "/usr/local/lib/python3.11/asyncio/runners.py", line 190, in run
    return runner.run(main)
           ^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.11/asyncio/runners.py", line 118, in run

    message = await websocket.recv()
              ^^^^^^^^^^^^^^^^^^^^^^

    raise self.connection_closed_exc()
websockets.exceptions.ConnectionClosedOK: received 1000 (OK) Websocket closed!,sid=iat000dc91f@dx18ad01d4a38a11f802!reason=server read msg timeout; then sent 1000 (OK) Websocket closed!,sid=iat000dc91f@dx18ad01d4a38a11f802!reason=server read msg timeout

不懂这是为什么，但是我发个普通的消息就会立马得到反馈

回答：

是我自己的问题，在发送数据的时候必须有 3 种数据包：012 分别代表起始帧、中间、结束、否则就会没响应直接结束
