如何禁用特定网址的弹簧安全性

Question

我正在使用无状态弹簧安全，但在注册的情况下我想禁用弹簧安全。我禁用了使用

antMatchers("/api/v1/signup").permitAll().

但它不起作用，我收到以下错误：

 message=An Authentication object was not found in the SecurityContext, type=org.springframework.security.authentication.AuthenticationCredentialsNotFoundException

我认为这意味着 spring 安全过滤器正在工作

我的 url 的顺序总是“/api/v1”

我的弹簧配置是

@Override
    protected void configure(HttpSecurity http) throws Exception {

         http.
         csrf().disable().
         sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).
         and().
         authorizeRequests().
         antMatchers("/api/v1/signup").permitAll().
         anyRequest().authenticated().
         and().
         anonymous().disable();
        http.addFilterBefore(new AuthenticationFilter(authenticationManager()), BasicAuthenticationFilter.class);
    }

我的身份验证过滤器是

@Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpRequest = asHttp(request);
        HttpServletResponse httpResponse = asHttp(response);

        String username = httpRequest.getHeader("X-Auth-Username");
        String password = httpRequest.getHeader("X-Auth-Password");
        String token = httpRequest.getHeader("X-Auth-Token");

        String resourcePath = new UrlPathHelper().getPathWithinApplication(httpRequest);

        try {

            if (postToAuthenticate(httpRequest, resourcePath)) {            
                processUsernamePasswordAuthentication(httpResponse, username, password);
                return;
            }

            if(token != null){
                processTokenAuthentication(token);
            }
            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 {
        }
    }

     private HttpServletRequest asHttp(ServletRequest request) {
            return (HttpServletRequest) request;
        }

        private HttpServletResponse asHttp(ServletResponse response) {
            return (HttpServletResponse) response;
        }

        private boolean postToAuthenticate(HttpServletRequest httpRequest, String resourcePath) {
            return Constant.AUTHENTICATE_URL.equalsIgnoreCase(resourcePath) && httpRequest.getMethod().equals("POST");
        }

        private void processUsernamePasswordAuthentication(HttpServletResponse httpResponse,String username, String password) throws IOException {
            Authentication resultOfAuthentication = tryToAuthenticateWithUsernameAndPassword(username, password);
            SecurityContextHolder.getContext().setAuthentication(resultOfAuthentication);
            httpResponse.setStatus(HttpServletResponse.SC_OK);
            httpResponse.addHeader("Content-Type", "application/json");
            httpResponse.addHeader("X-Auth-Token", resultOfAuthentication.getDetails().toString());
        }

        private Authentication tryToAuthenticateWithUsernameAndPassword(String username,String password) {
            UsernamePasswordAuthenticationToken requestAuthentication = new UsernamePasswordAuthenticationToken(username, password);
            return tryToAuthenticate(requestAuthentication);
        }

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

        private Authentication tryToAuthenticateWithToken(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;
        }

我的控制器是

@RestController
public class UserController {

    @Autowired
    UserService userService;

    /**
     * to pass user info to service
     */
    @RequestMapping(value = "api/v1/signup",method = RequestMethod.POST)
    public String saveUser(@RequestBody User user) {
        userService.saveUser(user);
        return "User registerted successfully";
    }
}

我对spring完全陌生，请帮助我怎么做？

Answer 1

当使用permitAll 时，它表示每个经过身份验证的用户，但是您禁用了匿名访问，因此这将不起作用。

您想要忽略某些 URL 以覆盖 configure 方法，该方法采用 WebSecurity 对象和 ignore 模式。

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/api/v1/signup");
}

并从HttpSecurity 部分中删除该行。这将告诉 Spring Security 忽略此 URL，并且不对它们应用任何过滤器。

Answer 2

我有更好的办法：

http
    .authorizeRequests()
    .antMatchers("/api/v1/signup/**").permitAll()
    .anyRequest().authenticated()

Answer 3

<http pattern="/resources/**" security="none"/>

或使用 Java 配置：

web.ignoring().antMatchers("/resources/**");

代替旧的：

 <intercept-url pattern="/resources/**" filters="none"/>

对于 exp 。禁用登录页面的安全性：

  <intercept-url pattern="/login*" filters="none" />

Answer 4

这可能不是您问题的完整答案，但是如果您正在寻找禁用 csrf 保护的方法，您可以这样做：

@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/web/admin/**").hasAnyRole(ADMIN.toString(), GUEST.toString())
                .anyRequest().permitAll()
                .and()
                .formLogin().loginPage("/web/login").permitAll()
                .and()
                .csrf().ignoringAntMatchers("/contact-email")
                .and()
                .logout().logoutUrl("/web/logout").logoutSuccessUrl("/web/").permitAll();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("admin").password("admin").roles(ADMIN.toString())
                .and()
                .withUser("guest").password("guest").roles(GUEST.toString());
    }

}

我已经包含了完整的配置，但关键是：

.csrf().ignoringAntMatchers("/contact-email")

Answer 5

@M.Deinum 已经写了答案。

我尝试使用 api /api/v1/signup。它将绕过过滤器/自定义过滤器，但浏览器为/favicon.ico 调用了一个附加请求，因此，我也在 web.ignoring() 中添加了它，它对我有用。

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/api/v1/signup", "/favicon.ico");
}

也许上述问题不需要。

Answer 6

如果你想忽略多个 API 端点，你可以使用如下：

 @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity.csrf().disable().authorizeRequests() 
            .antMatchers("/api/v1/**").authenticated()
            .antMatchers("api/v1/authenticate**").permitAll()
            .antMatchers("**").permitAll()
            .and().exceptionHandling().and().sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

Answer 7

我遇到了同样的问题，解决方法如下：（解释）

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .antMatchers(HttpMethod.POST,"/form").hasRole("ADMIN")  // Specific api method request based on role.
            .antMatchers("/home","/basic").permitAll()  // permited urls to guest users(without login).
            .anyRequest().authenticated()
            .and()
        .formLogin()       // not specified form page to use default login page of spring security.
            .permitAll()
             .and()
        .logout().deleteCookies("JSESSIONID")  // delete memory of browser after logout.

        .and()
        .rememberMe().key("uniqueAndSecret"); // remember me check box enabled.

    http.csrf().disable();  **// ADD THIS CODE TO DISABLE CSRF IN PROJECT.**
}
