Java – 如何使用 HtmlUnit 登录网站?
Java – How can I Log into a Website with HtmlUnit?
我正在编写一个 Java 程序来登录我学校用于 post 成绩的网站。
这是登录表单的url:https://ma-andover.myfollett.com/aspen/logon.do
这是登录表单的HTML:
<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>

<script>
setTimeout(function(){window.location.reload(true);}, 1800000);
</script>
</form>
我正在尝试使用以下代码登录:
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());
}
}
程序填写用户名框并点击"Log On"按钮,但不填写密码框。我可以更改什么以使该程序运行?我怀疑密码框的"type = 'password'"属性与问题有关,但如果我错了请指正。任何帮助表示赞赏。非常感谢。

You must enter a password.
OK
密码字段被禁用,直到您在 username
字段中输入内容。
通过设置用户名的值不会触发管理密码字段启用的事件。

要自动处理 JavaScript,您应该改用 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());
}
我用过:
final WebClient webClient = new WebClient())
HtmlPage page = webClient.getPage("url");
((HtmlTextInput) page.getHtmlElementById("usernameID")).setText("Username");
page.getHtmlElementById("passwordID").setAttribute("value","Password");
page.getElementsByTagName("button").get(0).click();
System.out.println(page.asText());
我以这种方式单击了按钮,因为我的按钮没有 ID、名称或值,但幸运的是它是页面上唯一的按钮。所以我只获取所有按钮标签(所有按钮标签)和 select 列表中要单击的第一个元素。
