Question

我曾尝试为chromecast编写一些webapps，将自己的网站投射到chromecast。在Chrome桌面上，它是非常棒的。我能够连接到chromecast发送消息和...

但是当我从手机上的Chrome浏览器加载网站时，每当我想向接收者发送消息时，它就会一直说连接到chromecast。

我不想为手机编写应用程序，并希望将其保留在webapp上。

这是SDK Developer的示例代码。

我调用函数转录，并将消息发送到我写的chrome接收器。它在桌面版上完美运行。但是在电话上，它一直在说连接到chrome cast。

有人知道在电话上工作是否有任何强制设置？

我已经研究了越来越多，并在Stackflow上找到了关于这个问题的一些其他线程。

How can I send a message to a custom Google Cast Receiver from Chrome for iOS?

似乎不可能这样做，因为它没有集成到手机上的镀铬。

然而，有人知道chromecats是否支持其他方式来沟通顺便说一句。发件人和收件人？
