Spring Security SwitchUserFilter exitUserUrl被忽略了嗎？

Question

我在spring security的SwitchUserFilter上遇到問題。 當我以ADMIN角色登錄時，可以切換用戶並再次返回。 問題是，當第二次切換用戶時，我似乎無法切換回去。 當我直接在瀏覽器中轉到/ secured / switch / back時，這會顯示在我的日志中。

[FilterChainProxy] : /secured/admin at position 1 of 10 in additional filter chain; firing Filter: 'SecurityContextPersistenceFilter'
...
[AbstractSecurityInterceptor] : Secure object: FilterInvocation: URL: /secured/admin; Attributes: [hasRole('ADMIN')]
[AbstractSecurityInterceptor] : Previously Authenticated: org.springframework.security.authentication.UsernamePasswordAuthenticationToken@99f3cebe: Principal: harry [OTHER]; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@2cd90: RemoteIpAddress: 0:0:0:0:0:0:0:1; SessionId: 756CEC9064C2B1B4D788624786F26137; Granted Authorities: OTHER, Switch User Authority [ROLE_PREVIOUS_ADMINISTRATOR,org.springframework.security.authentication.UsernamePasswordAuthenticationToken@6b846d6c: Principal: max [ADMIN]; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@fffe9938: RemoteIpAddress: 0:0:0:0:0:0:0:1; SessionId: 26B09EEF635C1758BE96B86AB6354434; Granted Authorities: ADMIN]
[AffirmativeBased] : Voter: org.springframework.security.web.access.expression.WebExpressionVoter@3e35ec54, returned: -1
[ExceptionTranslationFilter] : Access is denied (user is not anonymous); delegating to AccessDeniedHandler

通常，當用戶使用配置的/secured/switch/back url /secured/switch/back ， FilterChainProxy開始過濾對url / secured / switch / back的請求。 但是，第二次將該URL更改為/ secured / admin並拒絕了權限。

有人知道這里可能會發生什么嗎？

我有以下配置。

<beans:bean id="switchUserProcessingFilter" 
    class="org.springframework.security.web.authentication.switchuser.SwitchUserFilter">

    <beans:property name="userDetailsService" ref="org.example.CustomUserDetailsService"/>
    <beans:property name="switchUserUrl" value="/secured/admin/switch/user" />
    <beans:property name="exitUserUrl" value="/secured/switch/back" />
    <beans:property name="usernameParameter" value="username" />
    <beans:property name="successHandler" ref="RedirectingAuthenticationSuccessHandler" />
</beans:bean>

<beans:bean id="authenticationSuccessHandler" class="org.example.RedirectingAuthenticationSuccessHandler" />

<http use-expressions="true" access-denied-page="/secured/access/denied" >
    <custom-filter ref="switchUserProcessingFilter" position="SWITCH_USER_FILTER" />

    <intercept-url pattern="/secured/login" access="permitAll()" />
    <intercept-url pattern="/secured/login/auth" access="permitAll()" />
    <intercept-url pattern="/secured/switch/back" access="hasAnyRole('ADMIN', 'OTHER')" />
    <intercept-url pattern="/secured/admin/**" access="hasRole('ADMIN')" />
    <intercept-url pattern="/secured/other/**" access="hasRole('OTHER')" />

    <form-login
            login-page='/secured/login'
            login-processing-url="/secured/login/auth"
            authentication-success-handler-ref="authenticationSuccessHandler"
            username-parameter="username"
            password-parameter="password"
            />

    <logout logout-url="/secured/logout" logout-success-url="/secured/login" />

和成功經理

public class RedirectingAuthenticationSuccessHandler implements AuthenticationSuccessHandler {

    private static final Logger logger = LoggerFactory.getLogger(RedirectingAuthenticationSuccessHandler.class);

    private static final RoleBasedRedirectStrategy redirectHandler = new RoleBasedRedirectStrategy();

    /*
     *  Redirect request based on user role.
     *
     *  For example:
     *      Role ADMIN redirects to /secured/admin
     *      Role OTHER redirects to /secured/other
     */
    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {
        User user = (User) authentication.getPrincipal();
        logger.info("Authentication successful for {}", user);
        redirectHandler.handleRedirect(request, response, user);
    }
}

Answer 1

從問題注釋中提取：

您確定您的redirectHandler 沒有發送永久重定向（301）嗎？

客戶端可以緩存永久重定向。 因此，可能沒有對/secured/switch/back實際第二個請求，它直接轉到了先前解析的成功URL /secured/admin （這將導致訪問被拒絕 （403），因為您仍然以OTHER身份登錄）。

順便說一下，有一種發送臨時（302）重定向的方法 （也由Spring的DefaultRedirectStrategy使用 ）：

response.sendRedirect(targetUrl);
