Question

你可以看到我想要做的事情。

我希望通过在会话中提供单独的令牌来连接会话中的所有用户 sessionId，以便他们可以查看彼此的流媒体。但用户只能看到他们的 straming。我只需要为每个用户在我的页面上为div分配一个连接到任何令牌的div 特别是sessionId。

这是用户只能看到他们的流媒体的代码

Answer 1

您的会话和发布商对象超出了其他方法的范围，您可能会遇到错误。如果在方法之外定义会话和发布者变量a（），一切都将按预期工作。

<script type="text/javascript">
  var session, publisher;

  function sessionConnectedHandler(event)...
  ...
