Question

我的身份验证基于spring-boot-security-example。当我输入无效令牌时，我想抛出401 Unauthorized异常。但是，我总是找不到404资源。我的配置设置了一个异常处理，但它被忽略了 - 可能是因为之前添加了我的AuthenticationFilter而请求没有到达我的异常处理程序。

我需要改变什么来改变401异常？

我有一个身份验证过滤器：

public class AuthenticationFilter extends GenericFilterBean {

...

@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
    HttpServletRequest httpRequest = asHttp(request);
    HttpServletResponse httpResponse = asHttp(response);
    Optional<String> token = Optional.fromNullable(httpRequest.getHeader("X-Auth-Token"));

    try {
        if (token.isPresent()) {
            logger.debug("Trying to authenticate user by X-Auth-Token method. Token: {}", token);
            processTokenAuthentication(token);
            addSessionContextToLogging();
        }

        logger.debug("AuthenticationFilter is passing request down the filter chain");
        chain.doFilter(request, response);
    } catch (InternalAuthenticationServiceException internalAuthenticationServiceException) {
        SecurityContextHolder.clearContext();
        logger.error("Internal authentication service exception", internalAuthenticationServiceException);
        httpResponse.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
    } catch (AuthenticationException authenticationException) {
        SecurityContextHolder.clearContext();
        httpResponse.sendError(HttpServletResponse.SC_UNAUTHORIZED, authenticationException.getMessage());
    } finally {
        MDC.remove(TOKEN_SESSION_KEY);
        MDC.remove(USER_SESSION_KEY);
    }
}

private void addSessionContextToLogging() {
    ...
}

...

private void processTokenAuthentication(Optional<String> token) {
    Authentication resultOfAuthentication = tryToAuthenticateWithToken(token);
    SecurityContextHolder.getContext().setAuthentication(resultOfAuthentication);
}

private Authentication tryToAuthenticateWithToken(Optional<String> token) {
    PreAuthenticatedAuthenticationToken requestAuthentication = new PreAuthenticatedAuthenticationToken(token, null);
    return tryToAuthenticate(requestAuthentication);
}

private Authentication tryToAuthenticate(Authentication requestAuthentication) {
    Authentication responseAuthentication = authenticationManager.authenticate(requestAuthentication);
    if (responseAuthentication == null || !responseAuthentication.isAuthenticated()) {
        throw new InternalAuthenticationServiceException("Unable to authenticate Domain User for provided credentials");
    }
    logger.debug("User successfully authenticated");
    return responseAuthentication;
}

AuthenticationProvider实现：

@Provider
public class TokenAuthenticationProvider implements AuthenticationProvider {

@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
    Optional<String> token = (Optional) authentication.getPrincipal();
    if (!token.isPresent() || token.get().isEmpty()) {
        throw new BadCredentialsException("No token set.");
    }
    if (!myCheckHere()){
        throw new BadCredentialsException("Invalid token");
    }

    return new PreAuthenticatedAuthenticationToken(myConsumerObject, null, AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_API_USER"));
}

...

}

以及如下配置：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.
            csrf().disable().
            sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).
            and().
            anonymous().disable().
            exceptionHandling().authenticationEntryPoint(unauthorizedEntryPoint());

    http.addFilterBefore(new AuthenticationFilter(authenticationManager()), BasicAuthenticationFilter.class);
}


@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(tokenAuthenticationProvider());
}


@Bean
public AuthenticationProvider tokenAuthenticationProvider() {
    return new TokenAuthenticationProvider();
}

@Bean
public AuthenticationEntryPoint unauthorizedEntryPoint() {
    return (request, response, authException) -> response.sendError(HttpServletResponse.SC_UNAUTHORIZED);
}
}

Answer 1

我在这个帖子中找到了答案：Return HTTP Error 401 Code & Skip Filter Chains

而不是

httpResponse.sendError(HttpServletResponse.SC_UNAUTHORIZED, authenticationException.getMessage());

我需要致电

httpResponse.setStatus(HttpServletResponse.SC_UNAUTHORIZED);

当我不继续调用它并将状态设置为不同的代码时，链似乎会停止 - 异常被正确抛出

Answer 2

我通过在我的顶级@SpringBootApplication类中添加以下注释来解决它：

@EnableAutoConfiguration(exclude = {ErrorMvcAutoConfiguration.class})

Spring Boot无法找到其默认错误页面吗？

Answer 3

除了以上答案外，我还修改了代码以实现401，之前我获得了500个无效或丢失的令牌。

public class JwtAuthenticationTokenFilter extends AbstractAuthenticationProcessingFilter {

    public JwtAuthenticationTokenFilter() {
        super("/secure/**");
    }

    @Autowired
    private JWTService jwtService;

    @Override
    public Authentication attemptAuthentication(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws AuthenticationException, IOException, ServletException {


        String header = httpServletRequest.getHeader("Authorization");


        if (header == null || !header.startsWith("Bearer ")) {

            httpServletResponse.sendError(HttpServletResponse.SC_UNAUTHORIZED,
                    "Please pass valid jwt token.");


        }else if(jwtService.validate(header.substring(7))==null){

            httpServletResponse.sendError(HttpServletResponse.SC_UNAUTHORIZED,
                    "jwt token is invalid or incorrect");

        }
        else{

            String authenticationToken = header.substring(7);

            JwtAuthenticationToken token = new JwtAuthenticationToken(authenticationToken);
            return getAuthenticationManager().authenticate(token);
        }

        return null;

    }

}

Answer 4

我知道这是一个老问题。如果方便的话，我只是添加这个。

@Bean
public AuthenticationEntryPoint unauthorizedEntryPoint() {
    return (request, response, authException) -> response.sendError(HttpServletResponse.SC_UNAUTHORIZED, HttpStatus.UNAUTHORIZED.getReasonPhrase());
}

它应该也能工作。我刚刚调用了 sendError()

的另一个重载方法

Spring Boot Security不会抛出401 Unauthorized Exception，但404 Not Found
