我尝试在本地测试一个服务，它在启动时会在google云中创建一些pub子主题。我正在使用我的个人凭据连接到google的服务（我没有使用pub-sub模拟器）。但是，用户凭据似乎受到允许其使用的api的限制，而且看起来它们受到了很多限制。我遇到的问题是，在发送创建主题的请求后，应用程序将挂起大约10分钟，并且无法停止（通过在终端中按ctrl+c），我必须终止它。
应用程序启动时弹出的警告是：

Your application has authenticated using end user credentials from Google Cloud SDK. We recommend that most server applications use service accounts instead. If your application continues to use end user credentials from Cloud SDK, you might receive a "quota exceeded" or "API not enabled" error. For more information about service accounts, see https://cloud.google.com/docs/authentication/.

应用程序运行10分钟后，出现以下错误，表示http客户端超时时间很长，google的api需要很长时间才能响应：

我查看了文档，但没有说明如何为库的http客户端自定义超时。有人知道怎么做吗？我用的是谷歌云-pubsub:1.108.3
请注意，这个问题是关于在http客户机中设置超时的。我知道使用服务帐户的凭据可以解决这个问题，但是我想知道库是否提供了更改http客户机设置的选项。

我看不到在云pub/sub文档[1,2]中讨论的超时设置。但是，您可以在javautils中手动调整timeoutexception。这样，您将能够捕获超时异常。请参阅[3]以了解如何将超时异常用于等待终止。
awaittermination方法用于“阻塞直到关闭请求后所有工作都已完成执行，或超时发生，或当前线程中断，以先发生的为准”[4]。请注意，这通常用于在使用异步订阅等待消息时延长超时时间。
在java中，还有其他选项可以配置单线程超时，但在pubsub[5]上并不常用。此外，如您所述，如果没有正确配置这些凭据，即使您延长了超时时间，请求也不会成功。
