Thymeleaf Webflux Security,Csrf未添加到视图中

标签: spring-security thymeleaf spring-webflux

我正在尝试将csrf标签添加到表单中,但它似乎与mvc中的工作方式不同。

所以我做的是添加 <input type="hidden" th:name="${_csrf.parameterName}" th:value="${_csrf.token}" />

登录表单,但即使存在这些注释,_csrf属性也不存在

@EnableWebFluxSecurity
@EnableReactiveMethodSecurity

这是我的SecurityWebFilterChain:

 http
                .authorizeExchange().pathMatchers(
                "/landing",
                "/",
                "/register",
                "/login",
                "/favicon.ico",
                "/js/**",
                "/fonts/**",
                "/assets/**",
                "/css/**",
                "/webjars/**").permitAll()
                .anyExchange().authenticated()
                .and()
                .httpBasic()
                .and()
                .formLogin().loginPage("/login")
                .and().logout()

我错过了什么?

UPDATE 当我将带有csrf的隐藏输入标记包含在登录表单中时:

<input type="hidden" th:name="${_csrf.parameterName}" th:value="${_csrf.token}" />

我收到此错误:

org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "_csrf.parameterName" (template: "public/login" - line 75, col 17)

Caused by: org.springframework.expression.spel.SpelEvaluationException: EL1007E: Property or field 'parameterName' cannot be found on null

因为_csrf因某种原因为空,即使注释已到位。

登录控制器:

 @GetMapping("/login")
    public String login(Model model) {
        return "public/login";
    }

还尝试添加如下控制器建议:

@ControllerAdvice
public class SecurityAdvice {

    @ModelAttribute("_csrf")
    Mono<CsrfToken> csrfToken(final ServerWebExchange exchange) {

        final Mono<CsrfToken> csrfToken = exchange.getAttribute(CsrfToken.class.getName());

        return csrfToken.doOnSuccess(token -> exchange.getAttributes()
                .put(DEFAULT_CSRF_ATTR_NAME, token)).log();
    }
}

与此处使用的方法类似:https://github.com/daggerok/csrf-spring-webflux-mustache

然而,这会导致

java.lang.NullPointerException: null
    at com.a.Config.SecurityAdvice.csrfToken(SecurityAdvice.java:23) ~[classes/:na]

这一行是最后一个片段的返回部分。

这就是我要使其正常工作的方法。

@GetMapping("/login")
public Mono<String> login(ServerWebExchange exchange, Model model) {
    Mono<CsrfToken> token = exchange.getAttributeOrDefault(CsrfToken.class.getName(), Mono.empty());
    return token.map(t -> {
        model.addAttribute("_csrf", t);
        return "login";
    });
}

我必须加入thymeleaf-extras-springsecurity5(而不是springsecurity4)才能使它正常工作。

我找不到任何CsrfToken,这意味着@ mk88的回答也没有帮助,this guide也没有帮助。

一旦我包含以下依赖项,它就会按设计的那样完美地工作:

    <dependency>
        <groupId>org.thymeleaf.extras</groupId>
        <artifactId>thymeleaf-extras-springsecurity5</artifactId>
        <version>3.0.4.RELEASE</version>
    </dependency>

Thymeleaf的输出:

<form action="/members" method="POST" ><input type="hidden" name="_csrf" value="432033fd-1076-4620-9f99-d0220b6d3071"/>

在所有控制器上均可使用的最干净的解决方案是使用in the documentation(详细信息{{3}}):

@ControllerAdvice

答案 3 :(得分:0)

默认情况下,WebFlux中似乎没有将CsrfToken信息实际添加到模型中。 (请参阅https://github.com/spring-projects/spring-security/issues/6046

解决方法是添加订阅令牌信息的ControllerAdvice,并通过ComponentScan引用它,或将其声明为显式bean,如下所示:

(我正在使用Kotlin,但这在Java中应该以相同的方式工作)

import org.springframework.security.web.reactive.result.view.CsrfRequestDataValueProcessor.DEFAULT_CSRF_ATTR_NAME
import org.springframework.security.web.server.csrf.CsrfToken
import org.springframework.web.bind.annotation.ControllerAdvice
import org.springframework.web.bind.annotation.ModelAttribute
import org.springframework.web.server.ServerWebExchange
import reactor.core.publisher.Mono

@ControllerAdvice
class CsrfControllerAdvice {

    @ModelAttribute(value = DEFAULT_CSRF_ATTR_NAME)
    fun csrfToken(exchange: ServerWebExchange): Mono<CsrfToken> {
        return exchange.getAttributeOrDefault(CsrfToken::class.java.name, Mono.empty())
    }
}
