使用HtmlUnit时出错

Question

当我执行这个简单的代码将网站的内容作为文本时,它会显示我无法理解的错误.

import java.io.IOException;
import java.net.MalformedURLException;

import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;
import com.gargoylesoftware.htmlunit.ScriptException;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlPage;

public class sd {
    public static void main(String[] args) {
        sd vip=new sd();
        try {
            vip.homePage();
        } catch (Exception e) {
            e.printStackTrace();
        }

        System.out.print("sssss");
    }

    public void homePage() throws Exception, ScriptException {
        final WebClient webClient = new WebClient();
        final HtmlPage page =       
    (HtmlPage)webClient.getPage("http://timesofindia.indiatimes.com/");
        String pageAsText = page.asText();
        String pageAsXML = page.asXml();

        // System.out.println(pageAsXML);
        System.out.println("////////////////////output//////////////////////////"); 
        System.out.println(pageAsText);
        // System.out.println(pageAsXML);
        System.out.println("////////////////////output ends//////////////////////////"); 
    }

}

我得到的错误:

   ======= EXCEPTION START ========
Exception class=[com.gargoylesoftware.htmlunit.ScriptException]
com.gargoylesoftware.htmlunit.ScriptException: Exception invoking jsxFunction_write
    at com.gargoylesoftware.htmlunit.javascript.JavaScriptEngine$HtmlUnitContextAction.run(JavaScriptEngine.java:595)

Answer 1

WebClient::setThrowExceptionOnScriptError自HtmlUnit版本2.11以来,该方法已弃用.在较新版本中使用以下内容:

webClient.getOptions().setThrowExceptionOnScriptError(false);

Answer 2

将您的webClient设置为不抛出javascript异常

webClient.setThrowExceptionOnScriptError(假);

如果不是enougth,请在初始化webclient时将FF设置为客户端行为.

webClient = new WebClient(BrowserVersion.FIREFOX_3_6); webClient = new WebClient(BrowserVersion.FIREFOX_10); //取决于HtmlUnit版本
