Question

我需要一个使用Google Translation API将西班牙语转换为英语的示例。我尝试使用以下代码。它给出了一些例外。有人可以帮助我。

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：

Answer 1

您需要找出无法访问此主机的原因：ajax.googleapis.com

例外情况说：

 java.net.UnknownHostException: ajax.googleapis.com

javadoc表示抛出UnknownHostException以指示无法确定主机的IP地址。

您应该使用DNS。

nslookup ajax.googleapis.com

Answer 2

将您的DNS设置为google one

如果在linux机器上

sudo gedit /etc/resolv.conf

添加

nameserver 8.8.8.8
nameserver 8.8.4.4

或者如果在Windows上转到网络设置并为活动连接设置DNS

Answer 3

你没有api密钥，例如GoogleAPI.setKey（）;你需要这样的东西继续我猜
