Question

Angular 5 app需要登录用户。令牌请求被发送到/ oauth / token。由于CORS，预检OPTIONS请求（由Chrome发送）失败。

我尝试按照Spring Security 4.2上的示例以及Stackoverflow上的各种问题和响应进行操作。

这是我的代码：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

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

        http
        .cors().and()
        .csrf().disable()
            .anonymous().disable()
        .sessionManagement()
        .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
        .and()
        .authorizeRequests()
        .antMatchers("/signup").permitAll()
        .antMatchers("/oauth/token").permitAll()
        .antMatchers("/fapi/**").authenticated()
        .and()
        .httpBasic()
            .realmName("MY_REALM");
    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("http://example.com"));
        configuration.setAllowedMethods(Arrays.asList("HEAD", "GET", "PUT", "POST", "DELETE", "PATCH", "OPTIONS"));
        configuration.addAllowedHeader("*");
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
    ............
}

以下是Chrome的请求

General Headers

Request URL: http://api.example.com/oauth/token
Request Method: OPTIONS
Status Code: 401 
Remote Address: 127.65.43.21:80
Referrer Policy: no-referrer-when-downgrade


Request headers

响应：

Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Content-Language: en
Content-Length: 1111
Content-Type: text/html;charset=utf-8

WWW-Authenticate: Basic realm="MY_REALM"
X-Content-Type-Options: nosniff
X-Frame-Options: DENY

控制台中的错误：

Failed to load http://api.example.com/oauth/token: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://example.com' is therefore not allowed access. The response had HTTP status code 401.

我无法使用Spring提供的CorsFilter。

这里的工作有所帮助。

Spring security, cors error when enable Oauth2

最终代码的一部分

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
@WebFilter("/*")
public class SimpleCORSFilter implements Filter {

    public SimpleCORSFilter() {
    }

    @Override
    public void init(FilterConfig fc) throws ServletException {
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse resp,
                         FilterChain chain) throws IOException, ServletException {

        System.out.println("doFilter");
        HttpServletResponse response = (HttpServletResponse) resp;
        HttpServletRequest request = (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Credentials", "true");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Origin, origin, x-requested-with, authorization, Content-Type, Authorization, credential, X-XSRF-TOKEN");

        if ("OPTIONS".equalsIgnoreCase(request.getMethod())) {
            response.setStatus(HttpServletResponse.SC_OK);
        } else {
            chain.doFilter(req, resp);
        }    
    }

    @Override
    public void destroy() {
    }    
}

在安全配置中：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers(HttpMethod.OPTIONS, "/oauth/token");
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http
      //.cors().and()
        .csrf().disable()
            .anonymous().disable()
        .sessionManagement()
        .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
        .and()
        .authorizeRequests()
        .antMatchers("/signup").permitAll()
        .antMatchers("/oauth/token").permitAll()
        .antMatchers("/fapi/**").authenticated()
        .and()
        .httpBasic()
            .realmName("MY_REALM");
    }

    /*
    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("http://example.com"));
        configuration.setAllowedMethods(Arrays.asList("HEAD", "GET", "PUT", "POST", "DELETE", "PATCH", "OPTIONS"));
        configuration.addAllowedHeader("*");
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }*/
    ............
}

我还在等待一个让它与Spring Security的CorsFilter一起工作的例子。

代替您所做的，编写一个自定义的cors过滤器，如下所示

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class SimpleCorsFilter implements Filter {

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest request = (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Origin, x-requested-with, authorization, Content-Type, Authorization, credential, X-XSRF-TOKEN);

        if ("OPTIONS".equalsIgnoreCase(request.getMethod())) {
            response.setStatus(HttpServletResponse.SC_OK);
        } else {
            chain.doFilter(req, res);
        }
        }

        @Override
        public void init(FilterConfig filterConfig) {
        }

        @Override
        public void destroy() {
        }
    }

并将configure(HttpSecurity http)覆盖修改为

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        .and()
        .csrf().disable()
            .anonymous().disable()
        .sessionManagement()
        .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
        .and()
        .authorizeRequests()
        .antMatchers("/signup").permitAll()
        .antMatchers("/oauth/token").permitAll()
        .antMatchers("/fapi/**").authenticated()
        .and()
        .httpBasic()
            .realmName("MY_REALM");
    }
