尝试访问不安全的路由时出现 Gettig 错误

[英]Gettig error while trying to access unsecured route

我在我的 java 项目中使用 spring 安全来保护 web 服务。 我所有的 web 服务都在这里受到保护,是我使用的过滤器链配置:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            .cors().and()
            .csrf().disable()
            .sessionManagement()
            .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and()
            .addFilter(new JwtEmailAndPasswordAuthenticationFilter(authenticationManager(), jwtConfig, secretKey))
            .addFilterAfter(new JwtTokenVerifier(secretKey, jwtConfig),JwtEmailAndPasswordAuthenticationFilter.class)
            .authorizeRequests()
            .anyRequest()
            .authenticated();
}
    

现在我需要创建一个每个人都可以访问的 web 服务。 为此,我添加了这一行:

.and().authorizeRequests().antMatchers("/auth/reset").permitAll()

对于链式文件管理器,它看起来像这样:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            .cors().and()
            .csrf().disable()
            .sessionManagement()
            .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and()
            .addFilter(new JwtEmailAndPasswordAuthenticationFilter(authenticationManager(), jwtConfig, secretKey))
            .addFilterAfter(new JwtTokenVerifier(secretKey, jwtConfig),JwtEmailAndPasswordAuthenticationFilter.class)
            .authorizeRequests()
            .and().authorizeRequests().antMatchers("/auth/reset").permitAll()
            .anyRequest()
            .authenticated();
}

添加上面的行后,我得到异常 JWT not found,它来自这个由 addFilterAfter 触发的 JwtTokenVerifier bean。

我的问题是,在请求不安全的 web 服务时,如何防止触发 addFilterAfter 或仅安全路由所需的任何其他过滤器?

更新

这是 JwtTokenVerifier bean 的定义:

public class JwtTokenVerifier extends OncePerRequestFilter {
    private final SecretKey secretKey;
    private final JwtConfig jwtConfig;

    public JwtTokenVerifier(SecretKey secretKey,
                            JwtConfig jwtConfig) {
        this.secretKey = secretKey;
        this.jwtConfig = jwtConfig;
    }

    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response,
                                    FilterChain filterChain) throws ServletException, IOException {

        try {
            
            String authorizationHeader = request.getHeader(jwtConfig.getAuthorizationHeader());

            if (Strings.isNullOrEmpty(authorizationHeader) || !authorizationHeader.startsWith(jwtConfig.getTokenPrefix())) {
                filterChain.doFilter(request, response);
                return;
            }

            String token = authorizationHeader.replace(jwtConfig.getTokenPrefix(), "");

            try {

                Jws<Claims> claimsJws = Jwts.parser()
                        .setSigningKey(secretKey)
                        .parseClaimsJws(token);

                Claims body = claimsJws.getBody();

                String email = body.getSubject();

                var authorities = (List<Map<String, String>>) body.get("authorities");

                Set<SimpleGrantedAuthority> simpleGrantedAuthorities = authorities.stream()
                        .map(m -> new SimpleGrantedAuthority(m.get("authority")))
                        .collect(Collectors.toSet());

                Authentication authentication = new UsernamePasswordAuthenticationToken(
                        email,
                        null,
                        simpleGrantedAuthorities
                );

                SecurityContextHolder.getContext().setAuthentication(authentication);

            } catch (JwtException e) {
                throw new IllegalStateException(String.format("Token %s cannot be trusted", token));
            }

            filterChain.doFilter(request, response);
        } catch (JwtException e) {
        throw e;
    }
  }
}   

我知道你没有问这个,但我首先建议你使用 Spring 安全的内置 JWT 支持而不是构建你自己的。 安全很难,使用经过审查的支持可能更安全。

关于为不同的端点使用单独的身份验证机制的问题,您可以改为发布两个过滤器链,一个用于开放端点,一个用于基于令牌的端点,如下所示:

@Bean
@Order(0)
SecurityFilterChain open(HttpSecurity http) {
    http
        .requestMatchers((requests) -> requests.antMatchers("/auth/reset"))
        .authorizeHttpRequests((authorize) -> authorize.anyRequest().permitAll());

    return http.build();
}

@Bean
SecurityFilterChain tokenBased(HttpSecurity http) {
    http
        .authorizeHttpRequests((authorize) -> authorize.anyRequest().authenticated())
        .addFilter(...)
        .addFilterAfter(...);

    return http.build();
}

你有没有试过这样的事情:

 .and().authorizeRequests().antMatchers("...").permitAll().and().addFilter(...).authorizeRequests().anyRequest().authenticated().and()
