spring-security 禁用了csrf的Spring安全403

使用spring security,我已经看过类似的问题,但他们说尝试禁用cors & csrf。
我在浏览器上使用它,所以我需要csrf。但是仅仅简单的测试并不能改变结果。
登录时,我会获得一个访问令牌和刷新令牌。
使用此令牌会给我一个403禁止响应代码。
我的配置如下:

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.cors().and().csrf().disable();
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        http.authorizeRequests().antMatchers("/login").permitAll();
        http.authorizeRequests().antMatchers(GET, "/**").hasAnyAuthority("STUDENT");
        http.authorizeRequests().anyRequest().authenticated();
        http.addFilter(new CustomAuthenticationFilter(authenticationManagerBean()));
        http.addFilterBefore(new CustomAuthorizationFilter(), UsernamePasswordAuthenticationFilter.class);
    }

我想这可能与这个过滤器有关,但如果我将forbidden.value更改为其他内容,结果仍然是forbidden.value

public class CustomAuthorizationFilter extends OncePerRequestFilter { // INTERCEPTS EVERY REQUEST
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
        if(request.getServletPath().equals("/login")){ filterChain.doFilter(request,response); } // DO NOTHING IF LOGGING IN
        else{
            String authorizationHeader = request.getHeader(AUTHORIZATION);
            if(authorizationHeader != null && authorizationHeader.startsWith("Bearer ")){
                try {
                    String token = authorizationHeader.substring("Bearer ".length()); // TAKES TOKEN STRING AND REMOVES BEARER
                    // THIS NEEDS MAKING SECURE AND ENCRYPTED vvvvvvv
                    Algorithm algorithm = Algorithm.HMAC256("secret".getBytes()); // <<<<<<<<<<<<<<<<<<<<<<<
                    JWTVerifier verifier = JWT.require(algorithm).build(); // USING AUTH0
                    DecodedJWT decodedJWT = verifier.verify(token);
                    String email = decodedJWT.getSubject(); // GETS EMAIL
                    String[] roles = decodedJWT.getClaim("roles").asArray(String.class); // GETS ROLES
                    Collection<SimpleGrantedAuthority> authorities = new ArrayList<>();
                    stream(roles).forEach(role -> {  authorities.add(new SimpleGrantedAuthority(role)); }); // CONVERTS ALL USERS ROLE INTO AN AUTHORITY
                    UsernamePasswordAuthenticationToken authToken = new UsernamePasswordAuthenticationToken(email, null); // PASSWORD IS NULL AT THIS POINT
                    SecurityContextHolder.getContext().setAuthentication(authToken); // INSERTS TOKEN INTO CONTEXT // THIS SHOWS AUTHENTICATED FALSE, DETIALS FALSE AND GRANTED AUTHORITIES EMPTY
                    filterChain.doFilter(request, response); // GETS TO THIS LINE HERE
                }
                catch (Exception e){
                    response.setHeader("error" , e.getMessage() );
                    response.setStatus(FORBIDDEN.value());
                    Map<String, String> error = new HashMap<>();
                    error.put("error_message", e.getMessage());
                    response.setContentType(APPLICATION_JSON_VALUE);

                    new ObjectMapper().writeValue(response.getOutputStream(), error); // THEN SKIPS RIGHT TO THIS LINE HERE EVEN IF BREAKPOINTING BEFORE
                }
            }
            else{ filterChain.doFilter(request, response); }
        }
    }
}

调试显示它命中filterChain.doFilter(request, response),然后直接跳转到异常捕获objectMapper

这 条 线 UsernamePasswordAuthenticationToken authToken = new UsernamePasswordAuthenticationToken(email, null);
缺少 权限 :
UsernamePasswordAuthenticationToken authToken = new UsernamePasswordAuthenticationToken(email, null, authorities);

希望我的回答能有所帮助,你可以放下一个断点来改变行的响应状态,然后检查是谁以及为什么它返回403,它最终可以帮助你得到解决方案
1.在设置403状态的行上放置一个断点,以从堆栈帧中查看这是如何发生的。
假设它返回403,没有其他信息,但它必须设置响应的状态,对吗?因此,将断点放置到setStatus方法,我不知道它应该位于何处,在tomcat库、spring库或servlet库中。检查HttpResponse,它们是几个实现,为那些setStatus/setCode方法设置断点。(接下来,您可以看到它实际上发生在HttpResponseWrapper::setStatus)
1.分析堆栈帧以查看其中发生了什么
