【问题描述】：

在previous question of mine 中，我被告知了 DelegatingAuthenticationEntryPoint 类。

但是，我遇到了一个问题，即 spring 没有返回正确的 Http 响应状态。

这是我重写的配置方法

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();

    LinkedHashMap<RequestMatcher, AuthenticationEntryPoint> map = new LinkedHashMap<>();

    map.put(new AntPathRequestMatcher(WELCOME_PAGE), new Http403ForbiddenEntryPoint());
    map.put(new AntPathRequestMatcher(FOOD_SELECTION_PAGE + "/**"), new Http403ForbiddenEntryPoint());
    map.put(new AntPathRequestMatcher(CHECKOUT_URL), new Http403ForbiddenEntryPoint());
    map.put(new AntPathRequestMatcher(VERIFY_BADGE_URL), new Http403ForbiddenEntryPoint());
    map.put(new AntPathRequestMatcher(VERIFY_NAME_URL), new Http403ForbiddenEntryPoint());

    map.put(new AntPathRequestMatcher(ADMIN_PAGE), new LoginUrlAuthenticationEntryPoint(LOGIN_PAGE));
    map.put(new AntPathRequestMatcher(NEW_FOOD_PAGE), new LoginUrlAuthenticationEntryPoint(LOGIN_PAGE));
    map.put(new AntPathRequestMatcher(EDIT_FOOD_URL + "/**"), new LoginUrlAuthenticationEntryPoint(LOGIN_PAGE));
    map.put(new AntPathRequestMatcher(HIDE_FOOD_URL), new Http403ForbiddenEntryPoint());
    map.put(new AntPathRequestMatcher(SHOW_FOOD_URL), new Http403ForbiddenEntryPoint());
    map.put(new AntPathRequestMatcher(DELETE_FOOD_URL), new Http403ForbiddenEntryPoint());
    map.put(new AntPathRequestMatcher(REFRESH_EMPS_URL), new Http403ForbiddenEntryPoint());

    http.authorizeRequests()
            .antMatchers(WELCOME_PAGE,
                    FOOD_SELECTION_PAGE + "/**",
                    CHECKOUT_URL,
                    VERIFY_BADGE_URL,
                    VERIFY_NAME_URL).denyAll()
            .antMatchers(ADMIN_PAGE,
                    NEW_FOOD_PAGE,
                    EDIT_FOOD_URL + "/**",
                    HIDE_FOOD_URL,
                    SHOW_FOOD_URL,
                    DELETE_FOOD_URL,
                    REFRESH_EMPS_URL).hasAnyAuthority("ROLES_USER")
            .anyRequest().permitAll()
            .and().formLogin().loginPage(LOGIN_PAGE)
                .usernameParameter("username")
                .passwordParameter("pin")
                .defaultSuccessUrl(ADMIN_PAGE)
                .permitAll()
                .failureUrl(LOGIN_PAGE + "?badlogin")
            .and().exceptionHandling().authenticationEntryPoint(new DelegatingAuthenticationEntryPoint(map));
}

我正在使用邮递员执行对 VERIFY_BADGE_URL 的发布请求。如这些日志所示，DelegatingAuthenticationEntryPoint 将此请求正确映射到 Http403ForbiddenEntryPoint

2021-08-18 10:18:57,879 DEBUG [https-jsse-nio-8443-exec-5] org.springframework.security.web.authentication.DelegatingAuthenticationEntryPoint: Match found! Executing org.springframework.security.web.authentication.Http403ForbiddenEntryPoint@8f8351a

然后在进一步处理后，我注意到它最终被转换为 405 状态并返回给邮递员，如这些日志中所示。

我发现人们得到 403 而不是 405 的问题，我查看了this Baeldung page，它似乎表明它应该转到请求的入口点。我已经尝试验证我的 JSESSION id，然后转到 VERIFY_BADGE_URL，我仍然得到 405 状态。

任何指导将不胜感激！

【问题讨论】：

您不应该将您的配置方法注释为@Bean 而不是@Override？
我无法回答这个问题，但由于我被要求看一看并且确实对问题所在有一些模糊的了解，所以我会发表评论。在我看来，请求最终出现在 Boot 的 default "/error" 页面（不支持 POST 请求），但我不知道为什么。我会通过启动调试器、在应用程序使用的任何 servlet 中的某处设置断点并从头到尾跟踪请求来开始查找。祝你好运。

【解决方案1】：

感谢@neofelis 的回复，他提到了 /error 页面不支持发布请求。

这让我觉得我那里只有一个 @GetMapping 方法。因此，POST 方法当然会遇到 /error 并且不支持导致此错误的 post。

我通过将以下方法添加到错误控制器来解决此问题。

@PostMapping("/error")
@ResponseBody
public String handlePostError(HttpServletRequest request) {
    int status = getResponseStatus(request);

    if (status == HttpStatus.FORBIDDEN.value()) {
        return "uh uh uh, you didn't say the magic word ;)";
    }
    return "Well..... That doesn't seem right :/";
}

private int getResponseStatus(HttpServletRequest request) {
    Object status = request.getAttribute(RequestDispatcher.ERROR_STATUS_CODE);

    if (status != null) {
        return Integer.parseInt(status.toString());
    }
    return -1;
}
