如何获取appengine应用程序的当前服务器URL？ [英] How to get the current server URL of appengine app?

问题描述

我试图从代码中获取当前正在运行的appengine java应用程序的服务器URL。也就是说，如果应用程序在我的本地开发机器上运行，我想以某种方式返回 http：// localhost：8080 < a>但如果它在prod中运行，我想返回 http://myappid.appspot.com 。有没有可以做到这一点的Java或Appengine API？我希望没有手动更改和从配置文件或常量中读取。

I'm trying to get the server URL of a currently running appengine java app from code. That is, if the app is running on my local dev machine I would like to somehow get returned "http://localhost:8080" but if it is running in prod I'd like to be returned "http://myappid.appspot.com". Are there any java or appengine API's that can do this? I'd like to not have a to manually change and read from a config file or a constant.

谢谢。

推荐答案

您应该可以使用getServerName（）：

You should be able to use getServerName():

boolean local = "localhost".equals(httpServletRequest.getServerName());

如果您需要更多信息，还可以使用其他方法。 getServerPort（）。

There are other methods you can also use if you need more info, e.g. getServerPort().
