在我的场景中，用户需要在第一次登录之前更改密码。如何在登录页面之前使 cas 重定向 url？

在我的应用程序中，我已经定义了自己的控制器来处理某些 URL，并且还在 authenticationHandlers 下实现了我自己的自定义身份验证。

现在只留下这个机制在登录前重置密码。

谁能给我一个线索怎么做？

我的解决方案

  1. 创造
resetPasswordView.(class)=org.springframework.web.servlet.view.JstlView
resetPasswordView.url=/WEB-INF/view/jsp/default/ui/ResetPassword.jsp

在 default_views.properties

  1. 创造
public class testflowAction extends AbstractAction{
    private String origin;

    @Override
    protected Event doExecute(RequestContext rc) throws Exception {
        origin = rc.getRequestParameters().get("service");
        if(true)
            return result("setNew");
        else
            return result("setNew");
    }

}
  1. 在 login-wenflow.xml 中，替换

<transition on="success" to="sendTicketGrantingTicket" />和 <transition on="success" to="customFlowCheck" />

还添加

<action-state id="customFlowCheck">
        <evaluate expression="customCheckAction" />
  <transition on="ok" to="sendTicketGrantingTicket" />
  <transition on="setNew" to="resetPasswordView" />
</action-state>

和

<end-state id="resetPasswordView" view="resetPasswordView" />

我们公司也有类似的问题。成功登录后，用户必须被重定向到另一个页面。我们决定从动作状态 ID“realSubmit”添加另一个结果，这将表明流程的继续。我建议您首先让用户进行登录，以便他确认他是正确的用户。为此，您需要更改 AuthenticationViaFormAction 类中的提交方法。然后您需要销毁 TGT，并将用户重定向到重置密码的自定义流程操作。它看起来像这样：

    public final String submit(final RequestContext context, final Credentials credentials, final MessageContext messageContext) throws Exception {
    (...)
    //Login user, so we know that provided password is correct.
     WebUtils.putTicketGrantingTicketInRequestScope(context, this.centralAuthenticationService.createTicketGrantingTicket(credentials));
    // do custom logic, that check if it is first login attept:
    if( firstLoginAttempt(credentials) {
      //destroy TGT, so user won't stay logged-in after interrupting next step
      centralAuthenticationService.destroyTicketGrantingTicket(ticketGrantingTicketId);
      //redirect user to another action that will handle changing password
      return "changePassRequired"
    }

我不知道你如何检查密码是否是初始密码，所以我把它留给你。接下来在 login-webflow.xml 结果中添加转换：

    <action-state id="realSubmit">
    <evaluate expression="authenticationViaFormAction.submit(flowRequestContext,flowScope.credentials, messageContext)" />
    <transition on="warn" to="warn" />
    <transition on="success" to="sendTicketGrantingTicket" />
    <transition on="error" to="generateLoginTicket" />
    <transition on="accountDisabled" to="casAccountDisabledView" />
    <transition on="mustChangePassword" to="casMustChangePassView" />
    <transition on="accountLocked" to="casAccountLockedView" />
    <transition on="badHours" to="casBadHoursView" />
    <transition on="badWorkstation" to="casBadWorkstationView" />
    <transition on="passwordExpired" to="casExpiredPassView" />
    <transition on="changePassRequired" to="changePasswordPrepare" />
</action-state>

并添加自定义操作，您不妨使用与登录操作相同的表单，将其分为两种状态，例如：

<view-state id="changePasswordPrepare" view="resetPasswordView">
    <on-entry>
        <evaluate expression="resetPasswordAction.setupForm(flowRequestContext)" />
    </on-entry>
    <transition on="submit" bind="true" validate="true" to="resetPasswordRealAction">
    </transition>
</view-state>
<action-state id="resetPasswordRealAction">
    <evaluate expression="resetPasswordAction.submit(flowRequestContext)" />
    <transition on="success" to="sendTicketGrantingTicket" />
    <transition on="again" to="changePasswordPrepare" />
    <transition on="error" to="generateLoginTicket" />       
</action-state>

如果需要，resetPasswordAction.setupForm 将准备带有重置密码表单的自定义视图 resetPasswordAction.submit 将从您的表单中获取变量，并更改密码。类的片段可能看起来像这样：

public class resetPasswordAction extends FormAction {
  public final String submit(final RequestContext context) throws Exception {
    final Credentials previousCredentials = context.getFlowScope().get("loginCredentials");
    final String oldPass = context.getConversationScope().get("pass");
    final String newPassword = context.getConversationScope().get("password");
    final String newPasswordagain = context.getConversationScope().get("passwordagain");
    if (!newPassword.equals(newPasswordagain) {
      return "again";
    }
    if ( everythingIsOk(previousCredentials.getUsername(),oldPass,newPassword)) {
      Credentials credentials = new UsernamePasswordCredentials();
      credentials.setUsername(previousCredentials.getUsername());
      credentials.setPassword(newPassword);
      WebUtils.putTicketGrantingTicketInRequestScope(context, this.casService.createTicketGrantingTicket(credentials));
      return "success";
    }
    return "error";
  }
  public Event setupForm(RequestContext context) throws Exception {
    final Locale locale = LocaleContextHolder.getLocale();
    context.getFlashScope().put("language",locale);
    context.getFlashScope().put("service",context.getRequestScope().get("service");
  }
}

您可能会对CAM - CAS 帐户管理模块感兴趣，尽管它似乎处于早期的理论阶段。

您可能对cas 4感兴趣，现在处于 beta 版本，因为它似乎包含更多弹性身份验证逻辑。一，您可以在登录密码重置后使用。

您可以在成功登录时添加一个 JS 脚本，从您的特定 URL 重定向一个

document.location.href =“http://www....”

您可以个性化您的处理 JS。

我已经运行了一个 CAS 服务器，看来您应该通过 Spring WebFlow 进行自定义。按照我的胶水：

    <action-state id="validateForgotPassword">
    <on-entry>
        <set name="flashScope.pmTask" value="'forceChangePassword'"/>
    </on-entry>

    <evaluate expression="forgotPasswordTokenValidateAction" />
    <transition on="success" to="passwordManager"/>
    <transition on="error" to="badForgotPasswordTokenView" />
</action-state>
