I got 403 response code in this program, but I need to get 200 to getting back the search result, what can I do?

      String url="http://www.google.com/search?q=";
      String charset="UTF-8";
      String key="java";
      String query = String.format("%s",URLEncoder.encode(key, charset));
      URLConnection con = new URL(url+ query).openConnection();
      BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
      String inputLine;
      while ((inputLine = in.readLine()) != null) 
      System.out.println(inputLine);
      in.close();

推荐答案

Google阻止了Java发送的默认UserAgent。您可以使用另一个并欺骗Google。只需添加：

Google is blocking the default UserAgent sent by Java. You can use another one and trick Google. Simply add:

con.setRequestProperty（User-Agent，Mozilla / 5.0（Macintosh; U; Intel Mac OS X 10.4; en -US; rv：1.9.2.2）Gecko / 20100316 Firefox / 3.6.2）;

创建con后和开始之前读。

after creating the con and before starting to read.
