Java - How can I login to a site using HtmlUnit?
Stack overflow. I am writing a Java program to enter a site that my school uses to post grades.
This is the url of the login form: https://ma-andover.myfollett.com/aspen/logon.do
This is the HTML of the login form:
<form name="logonForm" method="post" action="/aspen/logon.do" autocomplete="off"><div><input type="hidden" name="org.apache.struts.taglib.html.TOKEN" value="30883f4c7e25a014d0446b5251aebd9a"></div>
<input type="hidden" id="userEvent" name="userEvent" value="930">
<input type="hidden" id="userParam" name="userParam" value="">
<input type="hidden" id="operationId" name="operationId" value="">
<input type="hidden" id="deploymentId" name="deploymentId" value="ma-andover">
<input type="hidden" id="scrollX" name="scrollX" value="0">
<input type="hidden" id="scrollY" name="scrollY" value="0">
<input type="hidden" id="formFocusField" name="formFocusField" value="username">
<input type="hidden" name="mobile" value="false">
<input type="hidden" name="SSOLoginDone" value="">
<center>
<img src="images/spacer.gif" height="15" width="1">
<script language="JavaScript">
document.forms[0].elements['deploymentId'].value = 'ma-andover';
</script>
<script language="JavaScript">
$(function()
{
$('form').attr('autocomplete', 'off');
var name = $('#username');
var password = $('#password');
name.attr('autocomplete', 'off');
password.attr('autocomplete', 'off');
if (name.val() == '')
{
password.attr('disabled','disabled');
}
});
</script>

I am trying to use the following code to login:
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.html.HtmlForm;
import com.gargoylesoftware.htmlunit.html.HtmlPage;
public class LoginAttempt {
public static void main(String[] args) throws Exception {
WebClient webClient = new WebClient();
HtmlPage page = (HtmlPage) webClient.getPage("https://ma-andover.myfollett.com/aspen/logon.do");
HtmlForm form = page.getFormByName("logonForm");
form.getInputByName("username").setValueAttribute("myUsername"); //works fine
form.getInputByName("password").setValueAttribute("myPassword"); //does not work
page = form.getInputByValue("Log On").click(); //works fine
System.out.println(page.asText());
}
}
The program fills in the username field and clicks the Login button, but does not fill in the password field. What can I change to make this program work? I suspect the "type =" password "" attribute in the password field has something to do with the problem, but please correct me if I'm wrong. Any help is appreciated. Thank you very much.

The password field is disabled until you enter something in the field username
. Setting a value in the username does not fire an event that controls the inclusion of the password field.
Below works
public static void main(String[] args) {
WebClient webClient = new WebClient();
try {
HtmlPage page = (HtmlPage) webClient
.getPage("https://ma-andover.myfollett.com/aspen/logon.do");
HtmlForm form = page.getFormByName("logonForm");
form.getInputByName("username").setValueAttribute("myUsername");
HtmlInput passWordInput = form.getInputByName("password");
passWordInput.removeAttribute("disabled");
passWordInput.setValueAttribute("myPassword");
page = form.getInputByValue("Log On").click(); // works fine
System.out.println(page.asText());
} catch (Exception e) {
e.printStackTrace();
} finally {
webClient.close();
}
}
Output signal

To handle JavaScript automatically, you must use type()
.
try (WebClient webClient = new WebClient()) {
HtmlPage page = (HtmlPage) webClient.getPage("https://ma-andover.myfollett.com/aspen/logon.do");
HtmlForm form = page.getFormByName("logonForm");
form.getInputByName("username").type("myUsername");
form.getInputByName("password").type("myPassword");
page = form.getInputByValue("Log On").click();
System.out.println(page.asText());
}
