java - RememberMeAuthenticationFilter 的 Spring Security authenticationSuccessHandler

Question

我想为我的登录过滤器实现自定义 AuthenticationSuccessHandler，即 org.springframework.security.web.authentication.rememberme.RememberMeAuthenticationFilter。

这是我的spring安全配置

        <security:remember-me key="spring_login_detail" services-ref="rememberMeServices"/>
        <security:form-login login-processing-url="/login"/>

        <security:logout
            invalidate-session="true"
            delete-cookies="JSESSIONID,SPRING_SECURITY_REMEMBER_ME_COOKIE"
            logout-url="/logout" 
        />
    </security:http>

    <security:global-method-security secured-annotations="enabled"  pre-post-annotations="enabled"/>

    <security:authentication-manager alias="authenticationManager">
        <security:authentication-provider ref="rememberMeAuthenticationProvider"/>
        <security:authentication-provider user-service-ref="customUserDetailsService">
            <security:password-encoder ref="passwordEncoder"/>
        </security:authentication-provider>
    </security:authentication-manager>

    <bean class="org.springframework.security.authentication.encoding.Md5PasswordEncoder" id="passwordEncoder"/>

    <bean id="mySuccessHandler" class="com.projectname.security.CustomSavedRequestAwareAuthenticationSuccessHandler"/>

    <bean id="customUserDetailsService" class="com.projectname.security.CustomUserDetailsService"/>

    <bean id="rememberMeServices" class="org.springframework.security.web.authentication.rememberme.TokenBasedRememberMeServices">
        <property name="key" value="jsfspring-sec" />
        <property name="userDetailsService" ref="customUserDetailsService" />
        <property name="alwaysRemember" value="false" />
        <property name="tokenValiditySeconds" value="1209600" />
        <property name="parameter" value="_spring_security_remember_me_input"/>
    </bean>

    <bean id="rememberMeAuthenticationProvider" class="org.springframework.security.authentication.RememberMeAuthenticationProvider">
        <property name="key" value="spring_login_detail"/>
    </bean>

    <bean id="rememberMeFilter" class="org.springframework.security.web.authentication.rememberme.RememberMeAuthenticationFilter">
        <property name="rememberMeServices" ref="rememberMeServices"/>
        <property name="authenticationManager" ref="authenticationManager" />
        <property name="authenticationSuccessHandler" ref="mySuccessHandler"/>
    </bean> 

</beans>

这是我自定义的 AuthenticationSuccessHandler 实现

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.security.core.Authentication;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationSuccessHandler;
import org.springframework.security.web.savedrequest.HttpSessionRequestCache;
import org.springframework.security.web.savedrequest.RequestCache;
import org.springframework.security.web.savedrequest.SavedRequest;
import org.springframework.util.StringUtils;

public class CustomSavedRequestAwareAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

    private RequestCache requestCache = new HttpSessionRequestCache();

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) throws ServletException, IOException {
        SavedRequest savedRequest = requestCache.getRequest(request, response);
        if (savedRequest == null) {
            clearAuthenticationAttributes(request);
            return;
        }

        String targetUrlParam = getTargetUrlParameter();
        if (isAlwaysUseDefaultTargetUrl()
                || (targetUrlParam != null
                && StringUtils.hasText(request.getParameter(targetUrlParam)))) {
            requestCache.removeRequest(request, response);
            clearAuthenticationAttributes(request);
            return;
        }

        clearAuthenticationAttributes(request);
    }

    public void setRequestCache(RequestCache requestCache) {
        this.requestCache = requestCache;
    }
}

问题是在成功验证后根本没有调用 onAuthenticationSuccess。我在 StackOverflow 上读到一个答案，它说我需要实现 onAuthenticationSuccess 而不是 SimpleUrlAuthenticationSuccessHandler。我试过这样做，仍然没有用。其他一切都很好，唯一的问题是每次我登录时，spring 都会将我重定向到 '/'。这不是我想要的，我只想返回 '200 OK'

Answer 1

假设我理解正确，无论身份验证如何发生，您都希望在身份验证成功时中断过滤器链并发送 HTTP 响应代码；即它可以是登录表单或记住我的身份验证。

因此，首先，将以下逻辑添加到您的 CustomSavedRequestAwareAuthenticationSuccessHandler:

// place where applicable
if (authentication != null) {
  response.setStatus(HttpServletResponse.SC_OK);
}

其次，定义一个新的过滤器，例如:

class HttpResponseAuthenticationFilter extends RememberMeAuthenticationFilter {

  protected  void   onSuccessfulAuthentication(HttpServletRequest request, HttpServletResponse response, Authentication authResult) {
    super.onSuccessfulAuthentication(request, response, authResult);
    if (authResult != null) {
      response.setStatus(HttpServletResponse.SC_OK);
    }
  }

} 

第三，在security:http部分定义customer filer为:

<custom-filter position="LAST" ref="myHttpResponseAuthFilter" />

第四，将成功处理程序的引用添加到您的 form-login 中:

<form-login ... authentication-success-handler-ref="mySuccessHandler" ... />

因为您的表单例份验证中缺少它。

此外，基于 Spring Security关于过滤器位置的文档，建议您不要对自定义过滤器使用auto-config。

注意:

1. 您看到此行为的原因是，当您看到登录表单时，它与记住我服务无关。表单处理决定了最终的目标 URL。
2. 在第一次之后，将由记住我的过滤器进行身份验证并再次需要发送 HTTP 响应代码。

我还建议阅读 this answer因为它可以更深入地了解 Spring Security 中表单登录、http 基本身份验证和记住我服务之间的区别。
