java - Google 翻译 API 的问题

Question

我需要一个使用 Google Translation API 将西类牙语转换为英语的示例。我尝试使用以下代码。它给出了一些异常(exception)。有人可以帮助我吗？

代码:

import  com.google.api.translate.*;
public class GoogleTranslator {

    /**
     * @param args

    */
    @SuppressWarnings("deprecation")
    public static void main(String[] args) {// TODO code application logic here


            try {
                Translate.setHttpReferrer("sp-en");
                String translatedText = Translate.translate("Hola mundo", Language.SPANISH, Language.ENGLISH);
                System.out.println(translatedText);
                } catch (Exception ex) {
                ex.printStackTrace(); }

    }
}

错误:

您需要找出为什么无法访问此主机:ajax.googleapis.com

异常说:

 java.net.UnknownHostException: ajax.googleapis.com 

javadoc 说抛出 UnknownHostException 表示无法确定主机的 IP 地址。

您应该使用 DNS。

nslookup ajax.googleapis.com
