Java 无效JWT令牌上的Spring安全访问控制允许源代码:*(CORS)问题
我在Spring Boot应用程序中配置了JWT安全性和Spring安全性。我对你有意见Java 无效JWT令牌上的Spring安全访问控制允许源代码:*(CORS)问题,java,spring-boot,spring-security,jwt,microservices,Java,Spring Boot,Spring Security,Jwt,Microservices,我在Spring Boot应用程序中配置了JWT安全性和Spring安全性。我对你有意见 Access-Control-Allow-Origin: * 标题,也称为CORS。我配置了应用程序,以便在每个服务器响应中都有标头,但一旦JWT令牌无效,服务器响应将显示403错误代码,但不允许访问控制源:*标头。这会导致浏览器将错误消息写入控制台: 加载失败http://... 未显示“访问控制允许来源”标题 在请求的资源上显示。起源'http://...因此, 不允许访问。响应的HTTP状态代码为4
Access-Control-Allow-Origin: *
标题,也称为CORS。我配置了应用程序,以便在每个服务器响应中都有标头,但一旦JWT令牌无效,服务器响应将显示403错误代码,但不允许访问控制源:*标头。这会导致浏览器将错误消息写入控制台:
加载失败http://... 未显示“访问控制允许来源”标题
在请求的资源上显示。起源'http://...因此,
不允许访问。响应的HTTP状态代码为403
这似乎是错误的,我希望获得Access Control Allow Origin:*响应中的标头,即使JWT令牌无效,服务器响应中有403错误代码。
现在我尝试了什么和我的代码

这里是JwtAuthenticationFilter类。请注意,为了验证令牌,它通过http调用其他微服务。此外,我的应用程序没有登录端点,因为登录是在其他microservice应用程序上实现的
public class JwtAuthenticationFilter extends BasicAuthenticationFilter {
private String header;
private String prefix;
private String validateLink;
public JwtAuthenticationFilter(String header, String prefix, String validateLink) {
super(new AuthenticationManager() {
public Authentication authenticate(Authentication authentication) throws AuthenticationException{
return null;
}
});
this.header = header;
this.prefix = prefix;
this.validateLink = validateLink;
}
@Override
protected void doFilterInternal(HttpServletRequest request,
HttpServletResponse response,
FilterChain chain)
throws ServletException, IOException {
// 1. get the authentication header. Tokens are supposed to be passed in the
// authentication header
String headerValue = request.getHeader(header);
// 2. validate the header and check the prefix
if (headerValue == null || !headerValue.startsWith(prefix)) {
chain.doFilter(request, response); // If not valid, go to the next filter.
return;
}
// 3. Get the token
String token = headerValue.replace(prefix, "");
try {
GatewayResponse gatewayResponse = validate(token);
String userId = gatewayResponse.getUserId();
/*
Roles could come from gateway or loaded from current
microservice database by user id. They are
hardcoded here to illustrate how to populate
SecurityContextHolder
*/
List<String> authorities = new LinkedList<String>();
authorities.add("USER");
authorities.add("ADMIN");
UsernamePasswordAuthenticationToken auth = new UsernamePasswordAuthenticationToken(userId, null,
authorities.stream().map(SimpleGrantedAuthority::new).collect(Collectors.toList()));
SecurityContextHolder.getContext().setAuthentication(auth);
addTokenToResponse(gatewayResponse.getAuthHeader(), response);
} catch (Exception e) {
// In case of failure. Make sure it's clear; so guarantee user won't be
// authenticated
SecurityContextHolder.clearContext();
}
// go to the next filter in the filter chain
chain.doFilter(request, response);
}
private void addTokenToResponse(String authHeaderValue, HttpServletResponse response) {
response.addHeader(header, prefix+authHeaderValue);
}
private GatewayResponse validate(String token) {
/HTTP call here, returns null if invalid token
...
}
}

存在类似问题,无法使其与CorsConfiguration Source一起工作。只有基于过滤器的CORS支持有助于:
@Bean
public FilterRegistrationBean filterRegistrationBean() {
final CorsConfiguration config = new CorsConfiguration();
config.setAllowCredentials(true);
config.addAllowedOrigin("http://localhost:4200");
config.addAllowedHeader("*");
config.addAllowedMethod("*");
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", config);
FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
return bean;
}
尝试使用CrosFilter。找到下面的示例
@Bean
public CorsFilter corsFilter() {
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
final CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowCredentials(true);
configuration.addAllowedOrigin("*");
configuration.addAllowedHeader("*");
configuration.addAllowedMethod("OPTIONS");
configuration.addAllowedMethod("HEAD");
configuration.addAllowedMethod("GET");
configuration.addAllowedMethod("PUT");
configuration.addAllowedMethod("POST");
configuration.addAllowedMethod("DELETE");
configuration.addAllowedMethod("PATCH");
source.registerCorsConfiguration("/**", configuration);
return new CorsFilter(source);
}
为过滤器链中的CorsFilter设置最高优先级有效。
@Bean
public CorsFilter corsFilter() {
final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
final CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowCredentials(true);
configuration.addAllowedOrigin("*");
configuration.addAllowedHeader("*");
configuration.addAllowedMethod("OPTIONS");
configuration.addAllowedMethod("HEAD");
configuration.addAllowedMethod("GET");
configuration.addAllowedMethod("PUT");
configuration.addAllowedMethod("POST");
configuration.addAllowedMethod("DELETE");
configuration.addAllowedMethod("PATCH");
source.registerCorsConfiguration("/**", configuration);
return new CorsFilter(source);
}
