Jsoup captcha登录用cookie(Jsoup captcha login with cookie)

Jsoup captcha登录用cookie(Jsoup captcha login with cookie)

我一直在尝试开发一个小应用程序，从我的学术页面获取验证码，将其显示给用户，用户输入验证码，程序应显示详细信息。 但是，我被困在登录页面本身。 我使用jsoup获取cookie，将验证码保存到文件夹，使用之前的cookie提交验证码和表单数据。 但我再次获得相同的登录页面。 请帮忙！

这是获取请求。 网站网址https://academics.vit.ac.in/parent/parent_login.asp

Response res = Jsoup.connect(webSiteURL).method(Method.GET).execute(); Map<String,String> cook = res.cookies(); String sessionid = res.cookie("ASPSESSIONIDSQHDAQRQ");

获得验证码后，这是发布请求。

Response login = Jsoup.connect(webSiteURL) .userAgent("Mozilla/5.0") .cookie("ASPSESSIONIDSQHDAQRQ", sessionid). data("message","Enter Verification Code of 6 characters exactly as shown.") .data("vrfcd",captcha).data("wdpswd","somedata").data("wdregno","somedata") .method(Method.POST).execute(); System.out.println(login.parse());

当我试着这个

System.out.println(login.cookies());

值为null，是一个线索？ 帮帮我！！ 谢谢！！

I have been trying to develop a small application that gets captcha from my academics page, displays it to the user, the user enters captcha and the program should display details. However, I am stuck at login page itself. I used jsoup to get the cookie,save captcha to a folder, submit captcha along with form data, using the previous cookie. But I get the same login page again. Please help!

This is the get request. Website url https://academics.vit.ac.in/parent/parent_login.asp

Response res = Jsoup.connect(webSiteURL).method(Method.GET).execute(); Map<String,String> cook = res.cookies(); String sessionid = res.cookie("ASPSESSIONIDSQHDAQRQ");

After getting the captcha, this is the post request.

Response login = Jsoup.connect(webSiteURL) .userAgent("Mozilla/5.0") .cookie("ASPSESSIONIDSQHDAQRQ", sessionid). data("message","Enter Verification Code of 6 characters exactly as shown.") .data("vrfcd",captcha).data("wdpswd","somedata").data("wdregno","somedata") .method(Method.POST).execute(); System.out.println(login.parse());

When I tried this

System.out.println(login.cookies());

The value is null, is that a clue?? Help me out!! Thanks!!

您确定要使用cookie检索验证码吗？ 请检查一下。 我的意思是，您可以下载验证码，例如：

Response res1 = Jsoup.connect("https://academics.vit.ac.in/parent/captcha.asp") .cookie("ASPSESSIONIDSQHDAQRQ", sessionid) .ignoreContentType(true) .method(Method.GET).timeout(30000).execute();

然后确保在登录帖子中使用正确的URL，即：

https://academics.vit.ac.in/parent/parent_login_submit.asp

那它应该工作正常。

希望能帮助到你。

Are you sure you are retrieving the captcha using the cookie too?. Please check that. I mean, you can download the captcha with something like:

Response res1 = Jsoup.connect("https://academics.vit.ac.in/parent/captcha.asp") .cookie("ASPSESSIONIDSQHDAQRQ", sessionid) .ignoreContentType(true) .method(Method.GET).timeout(30000).execute();

Then be sure that in the login post you are using the correct url, that is:

https://academics.vit.ac.in/parent/parent_login_submit.asp

Then it should work fine.

Hope it helps.
