Google App Engine java runtime absolute url

Question

I need to send out emails containing icon gifs. It seems that using absolute urls is the best way to achieve this. In order to do so, I need to get hold of the the appengine-web-app.xml and its and so I can build the absolute path.

Is there any straightforward way to get hold of this ?

Answer 1

如果在servlet中发送，则可以从请求中获取网址

HttpServletRequest.getServerPath();

Answer 2

You can use ModulesService :

ModulesService ms = ModulesServiceFactory.getModulesService();
String currentModule = ms.getCurrentModule();
String defVersion = ms.getDefaultVersion(currentModule);
String defaultModuleHostname = ms.getModuleHostname(currentModule, defVersion);
