Spring 云：微服务认证通过 Eureka Discovery 工作，但不通过 Zuul

Question

我是 Spring Cloud 的新手。我正在尝试使用 Spring Cloud Eureka Discovery 和 Zuul Gateway 构建一些微服务。

我可以通过 Zuul 网关访问微服务并执行操作，但前提是不涉及安全性。如果我的微服务是安全的，那么我无法通过 Zuul 做任何事情，因为它不 return 支持 JWT 令牌。如果我通过 Eureka 发现客户端完成它，它就像一个魅力。

可能是我的 Zuul 配置有问题？或者我可能选择了一种无效的方式来保护服务？提前致谢！

这是我的 Zuul 网关配置：

Application.class

@SpringBootApplication
@EnableZuulProxy
@EnableDiscoveryClient
public class GatewayServiceApplication {

    public static void main(String[] args) {
        SpringApplication.run(GatewayServiceApplication.class, args);
    }

    @Bean
    public Filter shallowEtagHeaderFilter() {
        return new ShallowEtagHeaderFilter();
    }
}

application.properties

eureka.client.service-url.defaultZone=http://localhost:8010/eureka/
server.port=8011
zuul.prefix=/services

bootstrap.properties

spring.application.name=gateway-service
# specify where config server is up
spring.cloud.config.uri=http://localhost:8001

这是我的微服务 JWT 和安全配置：

WebSecurityConfig.class

public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure (HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests()
                .antMatchers(HttpMethod.POST, "/login").permitAll()
                .anyRequest().authenticated()
                .and()
                // We filter the api/login requests
                .addFilterBefore(new JWTLoginFilter("/login", authenticationManager()), UsernamePasswordAuthenticationFilter.class)
                // And filter other requests to check the presence of JWT in header
                .addFilterBefore(new JWTAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
    }

    @Override
    protected void configure (AuthenticationManagerBuilder auth) throws Exception {
        // Create a default account
        auth.inMemoryAuthentication()
                .withUser("**")
                .password("**")
                .roles("**");
    }
}

TokenAuthenticationService.class

public class TokenAuthenticationService {
    static final long EXPIRATIONTIME = 864_000_000; // 10 days
    static final String SECRET = "*";
    static final String TOKEN_PREFIX = "Bearer";
    static final String HEADER_STRING = "Authorization";

    static void addAuthentication (HttpServletResponse res, String username) {
        String JWT = Jwts.builder()
                .setSubject(username)
                .setExpiration(new Date(System.currentTimeMillis() + EXPIRATIONTIME))
                .signWith(SignatureAlgorithm.HS512, SECRET)
                .compact();
        res.addHeader(HEADER_STRING, TOKEN_PREFIX + " " + JWT);
    }

    static Authentication getAuthentication (HttpServletRequest request) {
        String token = request.getHeader(HEADER_STRING);
        if (token != null) {
            // parse the token.
            String user = Jwts.parser()
                    .setSigningKey(SECRET)
                    .parseClaimsJws(token.replace(TOKEN_PREFIX, ""))
                    .getBody()
                    .getSubject();

            return user != null ?
                    new UsernamePasswordAuthenticationToken(user, null, Collections.emptyList()) :
                    null;
        }
        return null;
    }
}

JWTLoginFilter.class

public class JWTLoginFilter extends AbstractAuthenticationProcessingFilter {

    public JWTLoginFilter (String url, AuthenticationManager authManager) {
        super(new AntPathRequestMatcher(url));
        setAuthenticationManager(authManager);
    }

    @Override
    public Authentication attemptAuthentication (HttpServletRequest req, HttpServletResponse res)
            throws AuthenticationException, IOException, ServletException {

        AccountCredentials creds = new ObjectMapper().readValue(req.getInputStream(), AccountCredentials.class);
        return getAuthenticationManager().authenticate(
                new UsernamePasswordAuthenticationToken(
                        creds.getUsername(),
                        creds.getPassword(),
                        Collections.emptyList()
                )
        );

    }

    @Override
    protected void successfulAuthentication (HttpServletRequest req,
                                             HttpServletResponse res,
                                             FilterChain chain,
                                             Authentication auth)
            throws IOException, ServletException {
        TokenAuthenticationService.addAuthentication(res, auth.getName());
    }
}

JWTAuthenticationFilter.class

public class JWTAuthenticationFilter extends GenericFilterBean {
    @Override
    public void doFilter (ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
            throws IOException, ServletException {
        Authentication authentication = TokenAuthenticationService.getAuthentication((HttpServletRequest) servletRequest);

        SecurityContextHolder.getContext().setAuthentication(authentication);
        filterChain.doFilter(servletRequest, servletResponse);
    }
}

Answer 1

尝试定义以下内容。

zuul.sensitiveHeaders=Cookie,Set-Cookie

在 zuul 中，Cookie、Set-Cookie 和 Authroization header 是默认敏感的 header。如果你想在你的api服务器中授权header，你需要像上面那样在没有Authroizationheader的情况下重新定义它。

您也可以为每条路线定义它。请参考文档：http://cloud.spring.io/spring-cloud-netflix/spring-cloud-netflix.html [Cookies 和敏感 Headers]
