通过HTMLUnit与Java进行身份验证时遇到问题调试问题

分类：编程问答

如何解决通过HTMLUnit与Java进行身份验证时遇到问题调试问题

我无法通过网页上的HTMLUnit进行身份验证。我输入用户名和密码，然后单击登录，然后检查页面标题，它仍然是登录页面。所以我没有正确登录。

这是怎么回事？我正在尝试使用Fiddler和Charles进行调试，但是我看不到我的请求。此Java代码对给定网站进行身份验证是否有意义？有调试提示吗？ 请帮我！谢谢。

我的代码：

package com.company;

import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.*;
import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.jupiter.api.*;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.CookieManager;

public class Main {

  static WebClient webClient;
  static CookieManager cookieManager;
  static String username = "MyUsername";
  static String password = "MyPassword";

  @Before
  public static void init() throws Exception {
    webClient = new WebClient();
    cookieManager = new CookieManager();
    cookieManager = webClient.getCookieManager();
    cookieManager.setCookiesEnabled(true);
    webClient.getOptions().setTimeout(90000);
    webClient.setJavaScriptTimeout(90000);
  }

  @After
  public static void close() throws Exception {
    webClient.close();
    cookieManager.clearCookies();
  }

  public static void signIn() throws Exception {
    //Acquire location for URI,password,username,submitbutton
    HtmlPage page1 = webClient.getPage("https://h3c.mlspin.com/signin.asp#ath");


    HtmlForm form = page1.getFormByName("loginform");
    HtmlTextInput uName = form.getInputByName("user_name");
    HtmlPasswordInput passWord = form.getInputByName("pass");
    HtmlButton button = form.getFirstByXPath("//*[@id=\"loginForm\"]/table/tbody/tr[7]/td/button");

    uName.setValueAttribute(username);
    passWord.setValueAttribute(password);
    HtmlPage page2 = button.click();

    System.out.println("HTMLUNIT UserText : \n" + uName.getText());
    System.out.println("HTMLUNIT PassText : \n" + passWord.getText());

    System.out.println("Results p2   " + page2.getTitleText());
    System.out.println("Results p2   " + page2.getPage());
  }


  @Test
  public static void givenAClient_gatherInfo() throws Exception {
    webClient.getOptions().setJavaScriptEnabled(true);
    webClient.getOptions().setThrowExceptionOnScriptError(false);
    webClient.getOptions().setCssEnabled(false);
    webClient.getOptions().setRedirectEnabled(true);
    webClient.getCache().setMaxSize(0);

  }

  public static void main(String[] args) throws Exception {

    init();
    givenAClient_gatherInfo();
    signIn();
    close();

  }

</html>

解决方法

在javascript中有以下部分：

if (!_suppressCookieConsent && !cookieConsentUtil.cookieConsentExists()) {
    document.getElementById("loginForm").action="signin.asp";
}
else{                    
    document.getElementById("loginForm").action="validate_new.asp";
}

通过查看http请求，似乎validate_new.asp正在将302（重定向）返回到signin.asp。这可能有助于找到相关的请求。

我尝试了更深入的研究，但是我需要尝试运行您的代码，而我现在没有时间去做。如果我有时间的话，我会再来的，
