Chromecast - SIGN_IN_REQUIRED
Posted
技术标签:
【中文标题】Chromecast - SIGN_IN_REQUIRED【英文标题】： 【发布时间】：2014-03-28 04:44:20 【问题描述】：我的用户中只有一小部分遇到此错误，我终其一生都无法弄清楚。我使用GooglePlayServicesUtil.isGooglePlayServicesAvailable(downloadService) 来测试Play Services 是否可用，它总是返回SUCCESS。我设置了连接到 Chromecast 的通道，一切正常，直到我尝试使用 RemoteMediaPlayer.load。对于某些用户，结果总是SIGN_IN_REQUIRED，resolution: null。 status.toString() 是 Failed to load: StatusstatusCode=SIGN_IN_REQUIRED, resolution=null。我真的不确定我应该怎么做，或者如何为我的少数用户解决这个错误。
我不知道什么部分是相关的，所以我只是发布我的整个控制器类：

【问题讨论】：
【参考方案1】：奇怪的是你当时得到这样的状态码。想到的是用户可能没有登录他/她的 gmail 帐户或类似的东西。您是否有日志文件供我们查看，看看我们是否可以从上下文中获得更多信息？此外，可以肯定的是，此类用户会看到在电视上启动的应用程序，并且只有在加载媒体时才会引发错误？
【讨论】：
添加了日志。是的，它可以很好地显示启动画面，它只是拒绝实际加载任何内容。我有一台可以重现该问题的设备，它肯定已登录到 Gmail，除了没有 SIM 卡外，它似乎一切正常。 我们需要更多的日志，可能需要整个会话来查看正在发生的事情，并为 Play 服务打开调试日志。由于日志可能很大，请随时打开一个问题并将其附加到那里。 我在gist.github.com/daneren2005/c1cd23a8107f3730290c 附加了完整的日志。我看不出那里有什么特别的事情。我尝试使用 .setVerboseLoggingEnabled(true) 打开调试，但我不知道它实际上改变了什么。我有什么特别需要做的吗？如果您希望在 Chromecast 问题中继续讨论，我可以。 所以你可以自己重现这个？如果是这样，您能否尝试运行我们的一个 android 示例，看看它是否适合您。 我无法构建示例，因为无论我做什么，Gradle 都会出错。【参考方案2】：问题是由于使用了自签名证书。我没有意识到我的旧手机上的问题，因为我换了主机并在换手机后购买了普通证书。如果 SDK 能通过一个有用的错误，那就太好了。抛出的问题让您认为这是连接到 Play Services SDK 的问题，而不是实际使用的 URL 的问题。
【讨论】：
你指的是什么证书？ 我的应用程序允许人们使用自己的 Subsonic 服务器，可以是 http 或 https。使用 http 服务器或带有有效证书的 https 的人可以正常使用 Chromecast。每个使用自签名证书设置服务器的人都会遇到该错误。以上是关于Chromecast - SIGN_IN_REQUIRED的主要内容，如果未能解决你的问题，请参考以下文章
