Chromecast Receiver應用程序錯誤：WebSocket意外斷開連接：undefined

我試圖獲得基本的Chrome應用程序設置，我可以從Desktop Chrome向Chromecast接收器發送簡單的自定義消息。這些設備已被列入白名單，並且應用程序源位於白名單過程中指定的網址。此外，正在使用正確的API_ID，NAMESPACE對於接收者和發件人應用程序是相同的。Chromecast Receiver應用程序錯誤：WebSocket意外斷開連接：undefined

接收器應用程序加載，但只是在那之後我得到：

[ 0.230s] [goog.net.WebSocket] The WebSocket disconnected unexpectedly: undefined

這似乎是阻止我能夠發送自定義消息到Chromecast。

從發件人應用程序，我可以找到設備，連接並啓動接收器應用程序。我也能夠正確斷開發件人的stopActivity（）調用。

接收端的設置是：

var receiver = new cast.receiver.Receiver(APP_ID, NAMESPACE); 
var channelHandler = new cast.receiver.ChannelHandler(NAMESPACE); 

channelHandler.addChannelFactory(receiver.createChannelFactory(NAMESPACE)); 

channelHandler.addEventListener('error', function($e){ 
    console.log('JAC - Error!'); 
}); 

channelHandler.addEventListener('open', function($e){ 
    console.log('JAC - OnOpen!'); 
}); 

channelHandler.addEventListener('message', function($e){ 
    console.log('JAC - Message: ' + $e.type); 
}); 


receiver.start();

我還沒有準備好將它作爲一個完整的答案，因爲我不知道'Receiver'構造函數中有什麼'NAMESPACE'類型，但它應該是一個數組。如果不是，也許奇怪的事情發生？ – dowski

啊賓果！這似乎使錯誤消失了。您是否想將其作爲答案而不是評論發佈，以便我可以給您信任？ –

將其移至答案。謝謝！ – dowski
