Configure Spring for CORS

我正在尝试为CORS配置Spring以使用Angular web UI：

我试过这个：

@Configuration
@ComponentScan("org.datalis.admin.config")
public class AppConfig {
    @Bean
    public static PropertySourcesPlaceholderConfigurer propertyConfigurer() {
        PropertySourcesPlaceholderConfigurer conf = new PropertySourcesPlaceholderConfigurer();
        conf.setLocation(new ClassPathResource("application.properties"));
        return conf;
    }
    @Bean
    public FilterRegistrationBean<CorsFilter> corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("127.0.0.1");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        source.registerCorsConfiguration("/**", config);
        FilterRegistrationBean<CorsFilter> bean = new FilterRegistrationBean<CorsFilter>(new CorsFilter(source));
        bean.setOrder(0);
        return bean;
    }
}

带有 Angular FE 的 Apache 服务器在同一台服务器上与 Wildly 服务器一起运行，所以我为 source 配置了 127.0.0.1。

但我仍然得到：

Access to XMLHttpRequest at 'http://123.123.123.123:8080/api/oauth/token' from origin 'http://123.123.123.123' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.
auth:1 Failed to load resource: the server responded with a status of 404 (Not Found)

您知道我该如何解决此问题吗？

我尝试的第二种方式：

@Configuration
@EnableResourceServer
public class ResourceSecurityConfig extends ResourceServerConfigurerAdapter {
    @Override
    public void configure(ResourceServerSecurityConfigurer resources) {
        resources.resourceId("resource_id").stateless(true);
    }
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/users/**").permitAll()
                .anyRequest().authenticated()
                .and()
        .cors().disable()
        .authorizeRequests()
        .antMatchers(HttpMethod.OPTIONS, "/**").permitAll()
        .anyRequest()
        .fullyAuthenticated()
        .and()
        .httpBasic()
        .and()
        .csrf().disable();
    }
    @Bean
    public CorsConfigurationSource corsConfigurationSources() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "PATCH", "DELETE", "OPTIONS"));
        configuration.setAllowedHeaders(Arrays.asList("authorization", "content-type", "x-auth-token"));
        configuration.setExposedHeaders(Arrays.asList("x-auth-token"));
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

使用第二个配置，我得到了has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status. auth:1 Failed to load resource: the server responded with a status of 404 (Not Found)

实现此结果的最佳方法是什么？

允许的源是 127.0.0.1，但客户端的 IP 为 123.123.123.123。尝试更改此设置：

config.addAllowedOrigin("127.0.0.1");

对此：

config.addAllowedOrigin("123.123.123.123");

您需要

告诉Spring Security使用您创建的 CORS 配置。

在我的项目中，我以这种方式配置Spring Security：

@Override
protected void configure(HttpSecurity http) throws Exception
{
    http
        .authorizeRequests()
        .antMatchers("/rest/protected/**")
        .authenticated()
     //Other spring sec configruation and then:
    .and()
        .cors()
        .configurationSource(corsConfigurationSource())
}

corsConfigurationSource()在哪里：

@Bean
    CorsConfigurationSource corsConfigurationSource() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        boolean abilitaCors = new Boolean(env.getProperty("templating.oauth.enable.cors"));
        if( abilitaCors )
        {
            if( logger.isWarnEnabled() )
            {
                logger.warn("CORS ABILITATI! Si assume ambiente di sviluppo");
            }
            CorsConfiguration configuration = new CorsConfiguration();
            configuration.setAllowedOrigins(Arrays.asList("http://localhost:4200","http://localhost:8080", "http://localhost:8180"));
            configuration.setAllowedMethods(Arrays.asList(  RequestMethod.GET.name(),
                    RequestMethod.POST.name(), 
                    RequestMethod.OPTIONS.name(), 
                    RequestMethod.DELETE.name(),
                    RequestMethod.PUT.name()));
            configuration.setExposedHeaders(Arrays.asList("x-auth-token", "x-requested-with", "x-xsrf-token"));
            configuration.setAllowedHeaders(Arrays.asList("X-Auth-Token","x-auth-token", "x-requested-with", "x-xsrf-token"));
            source.registerCorsConfiguration("/**", configuration);
        }
        return source;
    }

我希望它有用

这是我

的工作@Configuration类，用于处理仅在开发环境中使用的 CORS 请求。

@Configuration
//@Profile(PROFILE_DEV)
  public class CorsConfiguration {
  @Bean
  public WebMvcConfigurer corsConfigurer() {
      return new WebMvcConfigurer() {
          @Override
          public void addCorsMappings(CorsRegistry registry) {
              registry.addMapping("/**")
                  .allowedOrigins("*")
                  .allowedHeaders("*")
                  .allowedMethods("*");
          }
      };
  }
}

您还必须将 Spring 安全性配置为忽略预检请求使用的HttpMethod.OPTIONS（作为您提到的例外）

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
  //...
    @Override
    public void configure(WebSecurity web) throws Exception {
      web.ignoring()
            //others if you need
            .antMatchers(HttpMethod.OPTIONS, "/**");
    }
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .csrf()
            .disable()
            .exceptionHandling()
            .and()
            .headers()
            .frameOptions()
            .disable()
            .and()
            .authorizeRequests()
            .antMatchers("/api/register").permitAll()
            .antMatchers("/api/activate").permitAll()
            .antMatchers("/api/authenticate").permitAll()
            .antMatchers("/api/**").authenticated();
    }
}

因为当您使用 cors 时，您有触发HttpMethod.OPTIONS的简单请求和预检请求

我建议您使用 WebMvcConfigurer，并在 addCorsMappings 方法中设置 CORS 配置。

像这样的东西

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
            .allowedOrigins("http://localhost:9798")
            .allowedMethods("POST", "GET")
            //.allowedHeaders("header1", "header2", "header3")
            //.exposedHeaders("header1", "header2")
            .allowCredentials(true).maxAge(3600);
    }
}

这里有一个带有CORS项目的全功能Spring的链接，只需下载并运行它。

https://github.com/reos79/spring-cors

它有一个html页面（person.html），这个页面除了调用端口（9797）上的服务外什么都不做。因此，您需要加载此项目两次，一次在端口 9797 上加载服务，另一次在端口（9798）上加载。然后在您的浏览器上，您调用服务器上的页面人员 localhost：9798，它将在文件应用程序中调用本地主机：9797 上的服务。

您需要

在控制器类中添加@CrossOrigin类级别，如下所示

@CrossOrigin
public class SampleController {
    // Your code goes here
}

对 REST 控制器类的注释

尝试将 bean 名称更改为 corsConfigurationSource，删除"s"

文档 https://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#cors

默认情况下使用名为 corsConfigurationSource 的 Bean
