谷歌演员接收器返回不可用答案

【问题标题】：google cast receiver returns unavailable anyway谷歌演员接收器返回不可用
【发布时间】：2014-10-04 13:47:02
【问题描述】：

我尝试了一些 googlecast 示例（例如 googlecast/CastHelloText-chrome）

但它的接收器在我的自定义接收器上返回“不可用”的任何样本。

首先，示例中的默认应用程序 ID（例如 '794B7BBF' ）运行良好。没有问题。
在Google Cast SDK Developer Console 上的示例中注册了receiver.html，并将应用程序ID 替换为已发布的，但在发件人上找到了任何接收者。
重启 chromecast，勾选“检查更新时发送此 Chromecast 的序列号”。复选框，重新初始化 chromecast 并再次注册序列号，但它们无效。

这里是访问receiver.html时chrome开发者工具控制台上的控制台日志

有什么想法吗？我期待着您的回复。谢谢。

【问题讨论】：

仔细检查您的序列号，它有时很难阅读，并且容易将“0”与“O”混淆，等等。
另外，作为测试，看看您是否可以在端口 9222 上打开到您的 chromecast 设备的调试 chrome 会话。
@AliNaddaf 感谢您的回复。我前一阵子试过了。首先，我无法在端口 9222 上打开调试 chrome 会话。我一次又一次地尝试检查序列号......
如果您无法访问端口 9222，那么您的设备没有为您的应用注册。常见问题有：(1) 序列号错误，(2) 设置 chromecast 时忘记勾选复选框
哦，你是对的。我得到了错误的 s/n。现在，我可以访问端口 9222。谢谢。

【解决方案1】：

有时，从 chromecast 桌面应用程序重新启动后，即使输入了正确的序列号，也无法访问端口 9222。为了确保重启设备，我必须通过手动重新连接 chromecast 来重启。
