大家好我无法为我的应用程序设置安全解决方案!所以我有一个REST API后端运行在http://localhost:51030并使用Spring Framework开发,而对于正面我有一个Angular 2应用程序(最新版本A.K.A. Angular 4),运行在http://localhost:4200 . 我在后端设置了CORS配置,如下所示:
public class CORSFilter implements Filter
{
// The list of domains allowed to access the server
private final List<String> allowedOrigins = Arrays.asList("http://localhost:4200", "http://127.0.0.1:4200");
public void destroy()
{
}
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException
{
// Lets make sure that we are working with HTTP (that is, against HttpServletRequest and HttpServletResponse objects)
if (req instanceof HttpServletRequest && res instanceof HttpServletResponse)
{
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
// Access-Control-Allow-Origin
String origin = request.getHeader("Origin");
response.setHeader("Access-Control-Allow-Origin", allowedOrigins.contains(origin) ? origin : "");
response.setHeader("Vary", "Origin");
// Access-Control-Max-Age
response.setHeader("Access-Control-Max-Age", "3600");
// Access-Control-Allow-Credentials
response.setHeader("Access-Control-Allow-Credentials", "true");
// Access-Control-Allow-Methods
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT");
// Access-Control-Allow-Headers
response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, " + CSRF.REQUEST_HEADER_NAME); // + CSRF.REQUEST_HEADER_NAME
}
chain.doFilter(req, res);
}
public void init(FilterConfig filterConfig)
{
}
}
使用此配置只能正常工作,我可以执行从角度应用程序到回弹的请求并获得响应并执行任何操作 . 但是,当我尝试设置CSRF安全解决方案时,没有任何作用 . 这是在后端设置的CSRF和安全配置:
public class CSRF
{
/**
* The name of the cookie with the CSRF token sent by the server as a response.
*/
public static final String RESPONSE_COOKIE_NAME = "XSRF-TOKEN"; //CSRF-TOKEN
/**
* The name of the header carrying the CSRF token, expected in CSRF-protected requests to the server.
*/
public static final String REQUEST_HEADER_NAME = "X-XSRF-TOKEN"; //X-CSRF-TOKEN
// In Angular the CookieXSRFStrategy looks for a cookie called XSRF-TOKEN
// and sets a header named X-XSRF-TOKEN with the value of that cookie.
// The server must do its part by setting the initial XSRF-TOKEN cookie
// and confirming that each subsequent state-modifying request includes
// a matching XSRF-TOKEN cookie and X-XSRF-TOKEN header.
}
public class CSRFTokenResponseCookieBindingFilter extends OncePerRequestFilter
{
protected static final String REQUEST_ATTRIBUTE_NAME = "_csrf";
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException
{
CsrfToken token = (CsrfToken) request.getAttribute(REQUEST_ATTRIBUTE_NAME);
Cookie cookie = new Cookie(CSRF.RESPONSE_COOKIE_NAME, token.getToken());
cookie.setPath("/");
response.addCookie(cookie);
filterChain.doFilter(request, response);
}
}
@Configuration
public class Conf extends WebMvcConfigurerAdapter
{
@Bean
public CORSFilter corsFilter()
{
return new CORSFilter();
}
@Override
public void addViewControllers(ViewControllerRegistry registry)
{
registry.addViewController("/login");
registry.addViewController("/logout");
}
}
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter
{
@Autowired
private RESTAuthenticationEntryPoint authenticationEntryPoint;
@Autowired
private RESTAuthenticationFailureHandler authenticationFailureHandler;
@Autowired
private RESTAuthenticationSuccessHandler authenticationSuccessHandler;
@Autowired
private RESTLogoutSuccessHandler logoutSuccessHandler;
@Resource
private CORSFilter corsFilter;
@Autowired
private DataSource dataSource;
@Autowired
public void globalConfig(AuthenticationManagerBuilder auth) throws Exception
{
auth.jdbcAuthentication()
.dataSource(dataSource)
.usersByUsernameQuery("select login as principal, password as credentials, true from user where login = ?")
.authoritiesByUsernameQuery("select login as principal, profile as role from user where login = ?")
.rolePrefix("ROLE_");
}
@Override
protected void configure(HttpSecurity http) throws Exception
{
//csrf is disabled for the moment
//http.csrf().disable();
//authorized requests
http.authorizeRequests()
.antMatchers("/api/users/**").permitAll()
.antMatchers(HttpMethod.OPTIONS , "/*/**").permitAll()
.antMatchers("/login").permitAll()
.anyRequest().authenticated();
//handling authentication exceptions
http.exceptionHandling()
.authenticationEntryPoint(authenticationEntryPoint);
//login configuration
http.formLogin()
.loginProcessingUrl("/login")
.successHandler(authenticationSuccessHandler);
http.formLogin()
.failureHandler(authenticationFailureHandler);
//logout configuration
http.logout()
.logoutUrl("/logout")
.logoutSuccessHandler(logoutSuccessHandler);
//CORS configuration
http.addFilterBefore(corsFilter, ChannelProcessingFilter.class);
//CSRF configuration
http.csrf().requireCsrfProtectionMatcher(
new AndRequestMatcher(
// Apply CSRF protection to all paths that do NOT match the ones below
// We disable CSRF at login/logout, but only for OPTIONS methods to enable the browser preflight
new NegatedRequestMatcher(new AntPathRequestMatcher("/login*/**", HttpMethod.OPTIONS.toString())),
new NegatedRequestMatcher(new AntPathRequestMatcher("/logout*/**", HttpMethod.OPTIONS.toString())),
new NegatedRequestMatcher(new AntPathRequestMatcher("/api*/**", HttpMethod.GET.toString())),
new NegatedRequestMatcher(new AntPathRequestMatcher("/api*/**", HttpMethod.HEAD.toString())),
new NegatedRequestMatcher(new AntPathRequestMatcher("/api*/**", HttpMethod.OPTIONS.toString())),
new NegatedRequestMatcher(new AntPathRequestMatcher("/api*/**", HttpMethod.TRACE.toString()))
)
);
// CSRF tokens handling
http.addFilterAfter(new CSRFTokenResponseCookieBindingFilter(), CsrfFilter.class);
}
}
问题在于正面和角度4配置,CSRF文档很差,并且在互联网上没有完整的CSRF实现示例 . 以下是我的登录服务:
@Injectable()
export class LoginService {
private loginUrl = 'http://localhost:51030/login';
constructor(private http: Http) {}
preFlight() {
return this.http.options(this.loginUrl);
}
login(username: string , password: string) {
let headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded');
let options = new RequestOptions({headers: headers});
let body = "username="+username+"&password="+password;
return this.http.post(this.loginUrl , body , options);
}
}
在登录组件中,我在ngOnInit生命周期钩子中执行选项请求:
@Component({
templateUrl: './login-layout.component.html'
})
export class LoginLayoutComponent implements OnInit {
credentials = {username: '' , password: ''};
constructor(private loginService: LoginService){}
ngOnInit() {
this.loginService.preFlight()
.subscribe();
}
login() {
this.loginService.login(this.credentials.username , this.credentials.password)
.subscribe(
response=>{
console.log(response) ;
},error=>{
console.log(error);
}
);
}
}
预检顺利,我在选项请求上获得了200 OK状态以及一个临时JSEEIONID和XSRF-TOKEN Cookie .
所以在我的应用程序模块中,我在angular docs中添加了这个:
{
provide: XSRFStrategy,
useValue: new CookieXSRFStrategy('XSRF-TOKEN', 'X-XSRF-TOKEN')
},
但是,当我尝试使用凭据或后面的任何请求执行POST请求时,我得到403 Forbidden:“无法验证提供的CSRF令牌,因为找不到会话 . ”
所以请问我该如何解决这个问题,任何人都可以指出正确的方向,因为我对如何使这项工作毫无头绪!谢谢!

我很惊讶你为CSRF和CORS做了很多工作,因为Spring Security和Angular都内置了支持.Spring Security默认启用了CSRF .
Spring安全手册有关于配置csrf的良好文档:https://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#csrf
谷歌搜索“Angular 2 Spring Security csrf”给出了几个例子(以及我如何找到你的帖子) . 这是一个:
