示例：

1.在fanyi.youdao.com底部点击api，

.
2.调用数据接口

.
3.填写相关后申请并复制链接

.
4.代码：

import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.net.MalformedURLException;import java.net.URL;import java.net.URLConnection;public class TestGet {    public static void main(String[] args) {        new ReadByGet().start();    }}class ReadByGet extends Thread {    public void run() {        try {            // 有道翻译api申请的网站链接,doctype改为xml            URL url = new URL(                    "http://fanyi.youdao.com/openapi.do?keyfrom=CLP-test&key=1870425496&type=data&doctype=xml&version=1.1&q=welcome");            URLConnection connection = url.openConnection();// 打开            InputStream is = connection.getInputStream();            InputStreamReader isr = new InputStreamReader(is,"UTF-8");//UTF-8可以不用            BufferedReader br = new BufferedReader(isr);            String line;            StringBuilder builder = new StringBuilder();            while ((line = br.readLine()) != null) {                builder.append(line);            }            br.close();            isr.close();            is.close();            System.out.println(builder.toString());        } catch (MalformedURLException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }    }}

5.结果：

6.复制到test.xml文件中，ctrl+i(格式化)
