CORS弹簧靴和angularjs无法正常工作

Question

我试图在另一个应用程序（spring-boot应用程序）上调用REST端点（angularjs）。应用程序在以下主机和端口上运行。

REST应用程序，使用spring boot，http://localhost:8080
HTML应用程序，使用angularjs，http://localhost:50029

我也在使用spring-security和spring-boot应用程序。从HTML应用程序，我可以对REST应用程序进行身份验证，但此后，我仍然无法访问任何REST端点。例如，我有一个如下定义的angularjs服务。

adminServices.factory('AdminService', ['$resource', '$http', 'conf', function($resource, $http, conf) {
    var s = {};
    s.isAdminLoggedIn = function(data) {
        return $http({
            method: 'GET',
            url: 'http://localhost:8080/api/admin/isloggedin',
            withCredentials: true,
            headers: {
                'X-Requested-With': 'XMLHttpRequest'
            }
        });
    };
    s.login = function(username, password) {
        var u = 'username=' + encodeURI(username);
        var p = 'password=' + encodeURI(password);
        var r = 'remember_me=1';
        var data = u + '&' + p + '&' + r;

        return $http({
            method: 'POST',
            url: 'http://localhost:8080/login',
            data: data,
            headers: {'Content-Type': 'application/x-www-form-urlencoded'}
        });
    };
    return s;
}]);

angularjs控制器如下所示。

adminControllers.controller('LoginController', ['$scope', '$http', 'AdminService', function($scope, $http, AdminService) {
    $scope.username = '';
    $scope.password = '';

    $scope.signIn = function() {
        AdminService.login($scope.username, $scope.password)
            .success(function(d,s) {
                if(d['success']) {
                    console.log('ok authenticated, call another REST endpoint');
                    AdminService.isAdminLoggedIn()
                        .success(function(d,s) {
                            console.log('i can access a protected REST endpoint after logging in');
                        })
                        .error(function(d, s) { 
                            console.log('huh, error checking to see if admin is logged in');
                            $scope.reset();
                        });
                } else {
                    console.log('bad credentials?');
                }
            })
            .error(function(d, s) {
                console.log('huh, error happened!');
            });
    };
}]);

在打电话给http://localhost:8080/api/admin/isloggedin时，我得到了一个401 Unauthorized。

在REST应用程序方面，我有一个CORS过滤器，如下所示。

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

    @Override
    public void destroy() { }

    @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", "http://localhost:50029");
        response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "X-Requested-With, X-Auth-Token");
        response.setHeader("Access-Control-Allow-Credentials", "true");

        if(!"OPTIONS".equalsIgnoreCase(request.getMethod())) {
            chain.doFilter(req, res);
        }
    }

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

我的spring安全配置如下所示。

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private RestAuthenticationEntryPoint restAuthenticationEntryPoint;

    @Autowired
    private JsonAuthSuccessHandler jsonAuthSuccessHandler;

    @Autowired
    private JsonAuthFailureHandler jsonAuthFailureHandler;

    @Autowired
    private JsonLogoutSuccessHandler jsonLogoutSuccessHandler;

    @Autowired
    private AuthenticationProvider authenticationProvider;

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private PersistentTokenRepository persistentTokenRepository;

    @Value("${rememberme.key}")
    private String rememberMeKey;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .exceptionHandling()
            .authenticationEntryPoint(restAuthenticationEntryPoint)
                .and()
            .authorizeRequests()
                .antMatchers("/api/admin/**").hasRole("ADMIN")
                .antMatchers("/", "/admin", "/css/**", "/js/**", "/fonts/**", "/api/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .successHandler(jsonAuthSuccessHandler)
                .failureHandler(jsonAuthFailureHandler)
                .permitAll()
                .and()
            .logout()
                .deleteCookies("remember-me", "JSESSIONID")
                .logoutSuccessHandler(jsonLogoutSuccessHandler)
                .permitAll()
                .and()
            .rememberMe()
                .userDetailsService(userDetailsService)
                .tokenRepository(persistentTokenRepository)
                .rememberMeCookieName("REMEMBER_ME")
                .rememberMeParameter("remember_me")
                .tokenValiditySeconds(1209600)
                .useSecureCookie(false)
                .key(rememberMeKey);
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .authenticationProvider(authenticationProvider);
    }
}

所有处理程序正在根据用户是否登录，无法进行身份验证或注销而写出类似{success: true}的JSON响应。 RestAuthenticationEntryPoint如下所示。

@Component
public class RestAuthenticationEntryPoint implements AuthenticationEntryPoint {

    @Override
    public void commence(HttpServletRequest req, HttpServletResponse resp, AuthenticationException ex)
            throws IOException, ServletException {
        resp.sendError(HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized");
    }

}

关于我遗失或做错的任何想法？

无需额外定义此过滤器只需添加此类。 Spring将扫描并为您添加它。 SimpleCORSFilter。这是一个例子：spring-enable-cors

Answer 2

如果最初您的程序不使用spring安全性并且无法承担代码更改，那么创建一个简单的反向代理就可以解决问题。就我而言，我使用Nginx进行以下配置：

http {
  server {
    listen 9090;
    location / {
      if ($request_method = 'OPTIONS') {
      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
      #
      # Custom headers and headers various browsers *should* be OK with but aren't
      #
      add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
      #
      # Tell client that this pre-flight info is valid for 20 days
      #
      add_header 'Access-Control-Max-Age' 1728000;
      add_header 'Content-Type' 'text/plain; charset=utf-8';
      add_header 'Content-Length' 0;
      return 204;
      }
      if ($request_method = 'POST') {
      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
      add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
      add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
      }
      if ($request_method = 'GET') {
      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
      add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
      add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
      }

      proxy_pass http://localhost:8080;
    }
  }
}

我的程序收听：8080。

REF：CORS on Nginx

Answer 3

这对我有用。

@EnableWebSecurity
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {

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

        http.cors();
    }

}

@Configuration
public class WebConfiguration implements WebMvcConfigurer {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry
            .addMapping("/**")
            .allowedMethods("*")
            .allowedHeaders("*")
            .allowedOrigins("*")
            .allowCredentials(true);
    }

}

Answer 4

我曾经遇到过类似的情况。经过研究和测试，这是我的发现：

使用Spring Boot，启用全局CORS的推荐方法是在Spring MVC中声明并结合细粒度@CrossOrigin配置： @Configuration public class CorsConfig { @Bean public WebMvcConfigurer corsConfigurer() { return new WebMvcConfigurerAdapter() { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**").allowedMethods("GET", "POST", "PUT", "DELETE").allowedOrigins("*") .allowedHeaders("*"); } }; } }
现在，由于您使用的是Spring Security，因此您必须在Spring Security级别启用CORS，以允许它利用Spring MVC级别定义的配置： @EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http.cors().and()... } } Here是非常优秀的教程，解释了Spring MVC框架中的CORS支持。

Answer 5

如果你想在不使用过滤器或没有配置文件的情况下启用CORS，只需添加即可

@CrossOrigin

到你的控制器顶部，它的工作原理。

Answer 6

这对我有用：

@Configuration
public class MyConfig extends WebSecurityConfigurerAdapter  {
   //...
   @Override
   protected void configure(HttpSecurity http) throws Exception {

       //...         

       http.cors().configurationSource(new CorsConfigurationSource() {

        @Override
        public CorsConfiguration getCorsConfiguration(HttpServletRequest request) {
            CorsConfiguration config = new CorsConfiguration();
            config.setAllowedHeaders(Collections.singletonList("*"));
            config.setAllowedMethods(Collections.singletonList("*"));
            config.addAllowedOrigin("*");
            config.setAllowCredentials(true);
            return config;
        }
      });

      //...

   }

   //...

}

Answer 7

我使用spring boot 2.1.0，对我有用的是

A.通过以下方式添加cors映射：

@Configuration
public class Config implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedOrigins("*");
    }
}

B.将以下配置添加到我的HttpSecurity以获得弹簧安全性

.cors().configurationSource(new CorsConfigurationSource() {

    @Override
    public CorsConfiguration getCorsConfiguration(HttpServletRequest request) {
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowedHeaders(Collections.singletonList("*"));
        config.setAllowedMethods(Collections.singletonList("*"));
        config.addAllowedOrigin("*");
        config.setAllowCredentials(true);
        return config;
    }
})

同样在Zuul代理的情况下，您可以使用此INSTEAD OF A和B（只需使用HttpSecurity.cors()在Spring安全性中启用它）：

@Bean
public CorsFilter corsFilter() {
    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    final CorsConfiguration config = new CorsConfiguration();
    config.setAllowCredentials(true);
    config.addAllowedOrigin("*");
    config.addAllowedHeader("*");
    config.addAllowedMethod("OPTIONS");
    config.addAllowedMethod("HEAD");
    config.addAllowedMethod("GET");
    config.addAllowedMethod("PUT");
    config.addAllowedMethod("POST");
    config.addAllowedMethod("DELETE");
    config.addAllowedMethod("PATCH");
    source.registerCorsConfiguration("/**", config);
    return new CorsFilter(source);
}

Answer 8

对我来说，使用弹簧安全时唯一能够100％工作的是跳过所有额外过滤器和豆子的额外毛茸茸以及任何间接的“神奇”人们一直暗示这对他们有用但不适合我。

相反，只需强制它使用普通的StaticHeadersWriter编写所需的标题：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

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

        http
            // your security config here
            .authorizeRequests()
            .antMatchers(HttpMethod.TRACE, "/**").denyAll()
            .antMatchers("/admin/**").authenticated()
            .anyRequest().permitAll()
            .and().httpBasic()
            .and().headers().frameOptions().disable()
            .and().csrf().disable()
            .headers()
            // the headers you want here. This solved all my CORS problems! 
            .addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Origin", "*"))
            .addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Methods", "POST, GET"))
            .addHeaderWriter(new StaticHeadersWriter("Access-Control-Max-Age", "3600"))
            .addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Credentials", "true"))
            .addHeaderWriter(new StaticHeadersWriter("Access-Control-Allow-Headers", "Origin,Accept,X-Requested-With,Content-Type,Access-Control-Request-Method,Access-Control-Request-Headers,Authorization"));
    }
}

这是我发现的最直接，最明确的方式。希望它可以帮助某人。

Answer 9

要构建上面的其他答案，如果你有Spring安全的Spring启动REST服务应用程序（不是Spring MVC），那么通过Spring安全启用CORS就足够了（如果你使用Spring MVC然后使用Yogen所提到的WebMvcConfigurer bean就可以了是的方式，因为Spring安全将委托给其中提到的CORS定义）

因此，您需要具有执行以下操作的安全配置：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Override
protected void configure(HttpSecurity http) throws Exception {
    //other http security config
    http.cors().configurationSource(corsConfigurationSource());
}

//This can be customized as required
CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    List<String> allowOrigins = Arrays.asList("*");
    configuration.setAllowedOrigins(allowOrigins);
    configuration.setAllowedMethods(singletonList("*"));
    configuration.setAllowedHeaders(singletonList("*"));
    //in case authentication is enabled this flag MUST be set, otherwise CORS requests will fail
    configuration.setAllowCredentials(true);
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}

}

此链接提供了相同的更多信息：https://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#cors

注意：

为prod部署的应用程序启用所有源（*）的CORS可能并不总是一个好主意。
可以通过Spring HttpSecurity定制启用CSRF而不会出现任何问题
如果你在应用程序中使用Spring启用了身份验证（例如通过UserDetailsService），那么必须添加configuration.setAllowCredentials(true);

测试了Spring boot 2.0.0.RELEASE（即Spring 5.0.4.RELEASE和Spring security 5.0.3.RELEASE）

Answer 10

检查一下：

@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
    ...
            .antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
    ...
}

Answer 11

扩展WebSecurityConfigurerAdapter类并覆盖@EnableWebSecurity类中的configure（）方法将起作用：下面是示例类

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

         http
        .csrf().disable()
        .exceptionHandling();
         http.headers().cacheControl();

        @Override
        public CorsConfiguration getCorsConfiguration(final HttpServletRequest request) {
            return new CorsConfiguration().applyPermitDefaultValues();
        }
    });
   }
}
