Question

The following code is an attempt to search google, and return the results as text or html. The code was almost entirely copied directly from code snippets online, and i see no reason for it to not return results from the search. How do you return google search results, using htmlunit to submit the search query, without a browser?

      import com.gargoylesoftware.htmlunit.WebClient;
      import java.io.*;
      import com.gargoylesoftware.htmlunit.html.HtmlPage;    
      import com.gargoylesoftware.htmlunit.html.HtmlInput;
      import com.gargoylesoftware.htmlunit.html.HtmlSubmitInput;


      import java.net.*;

       public class GoogleSearch {

      public static void main(String[] args)throws IOException, MalformedURLException
      {
        final WebClient webClient = new WebClient();

        HtmlPage page1 = webClient.getPage("http://www.google.com");
        HtmlInput input1 = page1.getElementByName("q");
        input1.setValueAttribute("yarn");

        HtmlSubmitInput submit1 = page1.getElementByName("btnK");

        page1=submit1.click();

        System.out.println(page1.asXml()); 

        webClient.closeAllWindows();
      }
    }

Answer 1

某些浏览器必须检测出,改变产生的超文本,因为当用<代码>1.getWebResponse(>)对超文本进行检测时,提交年份的名称是btnG,而不是btnK。 (这不是我所看到的)。作出这一改变,其结果将是预期的。

Answer 2

我只检查了这一情况。实际为2只角线虫:

btnK: on the google home page (where there s 1 long textbox in the middle of the screen). This time the button s id = gbqfa
btnG: on the google result page (where the main textbox is on top of the screen). This time the button s id = gbqfb
