我基本上尝试通过 metablogweb API 方法 getRecentPosts 获取最近的帖子。但是我得到的只是一个 UnknonHostException 我不知道为什么，因为名称是正确的，而且用户数据也是正确的。我错过了什么吗？

我的代码是：

    uri = URI.create("http://name.wordpress.com/");
    String user = "***";
    String passw = "***";
    int numberOfPosts = 3;
    int blogId = 42; //Not applicable for WordPress, can be any value and will be ignored.
    client = new XMLRPCClient(uri);
    client.setBasicAuthentication(user, passw);

    try {
  client.call("metaWeblog.getRecentPosts",blogId,user,passw,numberOfPosts);

    } catch (XMLRPCException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

谢谢任何帮助。
