Spring-Security:用CORS预闪获得401(尽管有http.cors())

Question

对于初学者，我想用基本的身份验证来保护我的一部分Restapi。当我尝试从 react 客户端访问endpoint时，我会在预检请求中不断获取 401。

我试图遵循这个指南，但没有成功:https://www.baeldung.com/spring-security-cors-preflight

我不确定这是否是问题的一部分，但另一部分只能使用某些自定义http标头访问。

我使用方法安全:

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = false)
class MethodSecurityConfig : GlobalMethodSecurityConfiguration() {
    override fun customMethodSecurityMetadataSource(): MethodSecurityMetadataSource = SecurityMetadataSource()

    override fun accessDecisionManager(): AccessDecisionManager = super.accessDecisionManager().apply {
        this as AbstractAccessDecisionManager
        decisionVoters.add(PrivilegeVoter())
    }
}

这是我的安全配置：

@Configuration
@EnableJpaAuditing(auditorAwareRef = "auditorProvider")
class SecurityConfig : WebSecurityConfigurerAdapter() {
    private val deviceRequestHeaderName: String = "X-DEVICE-ID"    
    private val platformRequestHeaderName: String = "X-PLATFORM-ID"

    @Autowired
    lateinit var users: AppUserRepository

    @Autowired
    lateinit var backendUsers: BackendUserRepository

    @Autowired
    lateinit var roles: RoleRepository

    val authManager by lazy { authenticationManager() }

    private val authProvider by lazy {
        PreAuthenticatedAuthenticationProvider().apply {
            setPreAuthenticatedUserDetailsService {
                val authId = it.principal as UserAuthId
                if (authId.deviceId == null) throw UsernameNotFoundException("No device-id to search for.")
                if (authId.platform == null) throw UsernameNotFoundException("Platform not specified.")
                val platform = try {
                    ApplicationPlatform.valueOf(authId.platform)
                } catch (e: IllegalArgumentException) {
                    throw UsernameNotFoundException("Unknown platform ${authId.platform}.")
                }
                val existingUser = users.findByUserDeviceIdAndPlatform(authId.deviceId, platform)
                if (existingUser != null) return@setPreAuthenticatedUserDetailsService existingUser

                users.save(AppUser(authId.deviceId, platform, roles))
            }
        }
    }

    val passwordEncoder by lazy { BCryptPasswordEncoder() }

    private val deviceIdFilter by lazy {
        HeaderFieldAuthFilter(deviceRequestHeaderName, platformRequestHeaderName).apply {
            setAuthenticationManager(authManager)
        }
    }

    override fun configure(auth: AuthenticationManagerBuilder) = auth {
        authenticationProvider(authProvider)

        val userDetailsService = BackendUserDetailsService(backendUsers)
        userDetailsService(userDetailsService).passwordEncoder(passwordEncoder)
    }

    override fun configure(http: HttpSecurity) = http {
        session {
            sessionCreationPolicy(SessionCreationPolicy.STATELESS)
        }
        exceptionHandling()

        addFilter(deviceIdFilter)
        authorizeRequests().anyRequest().authenticated()
        csrf().disable()
        httpBasic()

        cors().configurationSource { request ->
            CorsConfiguration().apply {
                allowedOrigins = listOf(ALL)
                allowedMethods = listOf(GET, POST, DELETE, PUT, OPTIONS).map { it.name }
                allowedHeaders = listOf(ALL)
                allowCredentials = true
                maxAge = 3600
            }
        }
    }

    @Bean
    fun auditorProvider(): AuditorAware<User> = AuditorAware<User> {
        val authentication = SecurityContextHolder.getContext().authentication
        val user = authentication.run { if (isAuthenticated) principal as? User else null }
        return@AuditorAware Optional.ofNullable(user)
    }
}

Answer 1

要为单个静止endpoint启用CORS，您可以使用以下方式对其进行注释：

@CrossOrigin

为了允许所有endpoint的CORS，您可以有一个这样的bean:

  @Bean
  public WebMvcConfigurer corsConfigurer() {
    return new WebMvcConfigurerAdapter() {
      @Override
      public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedMethods("GET", "POST", "PUT", "DELETE").allowedOrigins("*")
                .allowedHeaders("*");
      }
    };

Answer 2

我可以通过手动从身份验证中排除飞行前请求来解决这个问题。加上

antMatchers(OPTIONS, "/**").permitAll()

到AuthizeRequest（）配置完成了这一点。请注意，Options是对Httpmethod枚举值的直接引用，像这样导入

import org.springframework.http.HttpMethod.*

Stackoverflow帮助我到达那里的帖子：

• 飞行前响应的HTTP状态代码401无效-Spring
• 如何在Spring Boot Spring Security应用程序中配置COR

最初，我假设这应该由cors配置处理 - 显然不是。
