我们想以编程方式获取当前的谷歌页面。我们使用了许多具有不同编程语言的技术，但我们无法获得正确的（当前）谷歌页面。
Java 代码示例
public class GoogleParser {
public static void main(String[] args){
GoogleParser googleParser = new GoogleParser();
googleParser.execute();
}
public void execute(){
String[] params = {"ankara nüfusu"};
final URL url = encodeGoogleQuery(params);
System.out.println("Downloading [" + url + "]...\n\n\n\n\n");
try {
final String html = downloadString(url);
System.out.println(html);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private static String downloadString(final InputStream stream) throws IOException {
final ByteArrayOutputStream out = new ByteArrayOutputStream();
int ch;
while (-1 != (ch = stream.read()))
out.write(ch);
return out.toString();
}
private static String downloadString(final URL url) throws IOException {
final String agent = "Mozilla/21.0 (Windows; U; Windows 7; en-US)";
final URLConnection connection = url.openConnection();
connection.setRequestProperty("User-Agent", agent);
final InputStream stream = connection.getInputStream();
return downloadString(stream);
}
private static URL encodeGoogleQuery(final String[] args) {
try {
final StringBuilder localAddress = new StringBuilder();
localAddress.append("/search?q=");
for (int i = 0; i < args.length; i++) {
final String encoding = URLEncoder.encode(args[i], "UTF-8");
localAddress.append(encoding);
if (i + 1 < args.length)
localAddress.append("+");
}
return new URL("http", "www.google.com", localAddress.toString());
} catch (final IOException e) {
// Errors should not occur under normal circumstances.
throw new RuntimeException(
"An error occurred while encoding the query arguments.");
}
}
}

java 从 google 获取的 Html 页面与当前的 google 页面不同。
- 不同的结果
- 不包含 Google Now 结果（4,551 milyon(2011) 部分）
- 不包含谷歌图表结果（右侧安卡拉信息）
- 比当前页面更旧的页面
- 导航属性（网络、图像、视频）左侧，通常在下方搜索栏
你知道如何用编程的 java 语言获取谷歌的当前（最后）页面吗？然而，其他语言的解决方案对于解决问题很重要。
谢谢您的答复
