GWT检测GAE版本更改并重新加载 [英] GWT detect GAE version changes and reload
问题描述
我的用户每次平均使用我的GWT应用程序40分钟,因此,当我升级GAE后端的版本号时,他们在浏览器中运行的版本不会有相当长的一段时间匹配服务器上支持它的版本。
大部分功能都被破坏,抛出IncompatibleRemoteServiceExceptions。我怎样才能在客户端检测到这些?我没有看到从onFailure方法中获取错误代码的方法。
当您收到 IncompatibleRemoteServiceException
在 onFailure()
中,您需要提示用户重新加载页面。产生一个 DialogBox (modal& with glass)通知用户应用程序已过期,并且一个按钮点击后会调用 Window.Location.reload()
My users use my GWT app for an average of 40 minutes at a time, so when I upgrade the version number of the GAE backend, there's a long period of time when the version they're running in their browser doesn't match the version supporting it on the server.
Most functionality is broken, throwing IncompatibleRemoteServiceExceptions. How can I detect these on the client end? I don't see a way to get an error code out of the onFailure method.
When you receive an IncompatibleRemoteServiceException
in onFailure()
you need to prompt the user to reload the page. Spawn a DialogBox (modal & with glass) informing the user that the application is out of date and a button that, when clicked, calls Window.Location.reload()
