如何从Chrome for iOS发送消息给自定义Google Cast Receiver？ [英] How can I send a message to a custom Google Cast Receiver from Chrome for iOS?

问题描述

我正在使用 CastHelloText-chrome 示例，并且能够让所有工作都正常运行但是，当我尝试在我的iOS设备上使用Chrome时，尝试创建会话时收到以下错误消息：

{code：channel_error，description：操作无法完成（com.google.chrome.ios.cast错误2）}

执行以下操作时会发生此错误：

  chrome .cast.requestSession（function（e）{
 session = e; 
 session.sendMessage（namespace，message，onSuccess.bind（this，Message sent：+ message），onError）; 
}，onError）; 
  

具体来说，这似乎发生在 requestSession 函数调用（嵌套回调从未实际执行）。

直到这一点似乎都行得通。事实上，在我的iOS设备上，我甚至会收到弹出式窗口，询问投向哪里（Chromecast），一旦我选择它，我的Chromecast确实会显示我的自定义接收器。然而，我仍然收到这个错误消息，并且从来没有得到一个会话对象，所以我不能发送消息到接收器。

就像我说的，这似乎工作正常在我的桌面版Chrome浏览器上，但无法在iOS Chrome浏览器上运行。此示例不适用于iOS设备吗？有没有一种方法可以使它工作？ 解决方案

手机上的Chrome和手机上的Chrome并不相同。您需要使用 iOS API 。以 CastHelloText-ios 作为参考使用示例应用程序。

I'm using the CastHelloText-chrome example and am able to get it all working just fine from the Chrome browser on my desktop, however, when I try to use Chrome on my iOS device, I receive the following error when trying to create a session:

{ "code": "channel_error", "description": "The operation couldn't be completed. (com.google.chrome.ios.cast error 2.)" }

This error happens when executing the following:

chrome.cast.requestSession(function(e) {
    session = e;
    session.sendMessage(namespace, message, onSuccess.bind(this, "Message sent: " + message), onError);
  }, onError);

Specifically, this seems to happen on the requestSession function call (the nested callback never actually executes).

Everything up until this point seems to work. In fact, on my iOS device, I even receive the popup asking where to cast to (Chromecast) and once I select it, my Chromecast does indeed display my custom receiver. However, I still receive that error message and never get a session object, so I can't send messages to the receiver.

Like I said, this seems to work fine on my desktop Chrome browser, but does not work on my iOS Chrome browser. Does this sample not work on iOS devices? Is there a way to make it work?

解决方案

Chrome on desktop and Chrome on mobile are not the same. You need to use the iOS API. Use the sample app for CastHelloText-ios as a reference.
