谷歌应用程序引擎Java - 使用低级API来获取数据 - 一些困难

在 Google App Engine for Java Web 应用程序中，我尝试使用低级 api 来调用 XML RPC ...查看文档后，我找到了使用低级 API 进行连接的以下代码 - 这就是我的原因想要使用 Low Level API 是这样我可以自己设置超时值 -

         String mrtime="120";
         java.lang.Double maxresponsetime;
         maxresponsetime = Double.valueOf(mrtime).doubleValue();
         HTTPRequest req=  new  HTTPRequest(url, HTTPMethod.GET, disallowTruncate().setDeadline(maxresponsetime));
         HTTPResponse response= com.google.appengine.api.urlfetch.URLFetchServiceFactory.getURLFetchService().fetch(req);
         String line="";
         String resp="";
         resp=new String(response.getContent(), "UTF-8");

上面的代码适用于 GAE 访问远程 URL 的场景...但是我还必须发送包含函数名称的 XML 消息以及输入参数（这些存储在名为的变量中'message')... 如何将该消息发送到远程 URL，然后获取响应？

In a Google App Engine for Java web app, I am trying to use the low level api to invoke an XML RPC ...After looking at the docs, I figured out the following code to connect using low level API-the reason why I want to use Low Level API is so that I can set the timeout value myself--

         String mrtime="120";
         java.lang.Double maxresponsetime;
         maxresponsetime = Double.valueOf(mrtime).doubleValue();
         HTTPRequest req=  new  HTTPRequest(url, HTTPMethod.GET, disallowTruncate().setDeadline(maxresponsetime));
         HTTPResponse response= com.google.appengine.api.urlfetch.URLFetchServiceFactory.getURLFetchService().fetch(req);
         String line="";
         String resp="";
         resp=new String(response.getContent(), "UTF-8");

The above code is suitable for a scenario where the remote URL is accessed by GAE...However I have to also send an XML message containing name of function as well as input parameters (these are stored in variable named 'message')... How do I send that message to the remote URL, and after that obtain the response?
