我正在编写一个小型Java程序来获取给定Google搜索词的结果数量.出于某种原因,在Java中我得到403 Forbidden但我在Web浏览器中获得了正确的结果.码:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;


public class DataGetter {

    public static void main(String[] args) throws IOException {
        getResultAmount("test");
    }

    private static int getResultAmount(String query) throws IOException {
        BufferedReader r = new BufferedReader(new InputStreamReader(new URL("https://www.google.com/search?q=" + query).openConnection()
                .getInputStream()));
        String line;
        String src = "";
        while ((line = r.readLine()) != null) {
            src += line;
        }
        System.out.println(src);
        return 1;
    }

}

而错误:

Exception in thread "main" java.io.IOException: Server returned HTTP response code: 403 for URL: https://www.google.com/search?q=test
