java - 如何使用java代码从这个url获取文件？

Question

为了使用谷歌翻译API，我找到了这个网址

http://translate.google.com/translate_a/t?client=t&text=revenge&hl=en&sl=en&tl=hi&ie=UTF-8&oe=UTF-8&multires=1&otf=1&ssel=3&tsel=3&sc=1

如果您点击它，您将获得一个带有准确翻译的 json 格式的文件。 为了使用 java 程序检索此文件，我编写了以下代码。

    String word = "revenge";

    System.setProperty("http.proxyHost", "172.30.0.16");
    System.setProperty("http.proxyPort", "3128");

    URL url = new URL("http://translate.google.com/translate_a/t?client=t&text="+word+"&hl=en&sl=en&tl=hi&ie=UTF-8&oe=UTF-8&multires=1&otf=1&ssel=3&tsel=3&sc=1");
    url.openConnection();
    InputStream reader = url.openStream();
    FileOutputStream writer = new FileOutputStream("t");
    byte[] buffer = new byte[153600];
    int bytesRead = 0;
    while ((bytesRead = reader.read(buffer)) > 0)
    {  
       writer.write(buffer, 0, bytesRead);
       buffer = new byte[153600];
    }
    writer.close();
    reader.close();

但它显示以下错误

线程“main”中出现异常 java.io.IOException:服务器返回 HTTP 响应代码:403，URL:http://translate.google.com/translate_a/t?client=t&text=Moon&hl=en&sl=en&tl=hi&ie=UTF-8&oe=UTF-8&multires=1&otf=1&ssel=3&tsel=3&sc=1 在 sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1403) 在 java.net.URL.openStream(URL.java:1029) 在 smsMain.main(smsMain.java:20

希望能得到一些帮助。因为我们是手动获取文件，但使用程序是禁止的。

来自Google Translate主页:

Google Translate API is available as a paid service. See the Pricing and FAQ pages for details.

因此出现错误并不奇怪。
