所请求的资源上不存在“ Access-Control-Allow-Origin”标头(春季)

我知道论坛上有很多关于此问题的话题,但仍然没有找到解决方案。

因此,我在vps上的私有JVM / tomcat 8.5.30中部署了两个应用程序。一个是我的ROOT.war,另一个是admin.war,它们可以从http://example.comhttp://example.com/admin

访问

在我安装ssl证书之前,一切正常。安装它并强制https重定向后,我的admin.war遇到了问题(现在它们都可以从https://example.comhttps://example.com/admin访问)

我的管理员使用很多jquery(我无法更改它),每次尝试提交内容时都会收到此错误

Access to XMLHttpRequest at 'http: //example.com/admin/add' from origin 'https: //example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

因此,我正在尝试通过Spring Security解决此问题。在我的安全配置中,

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
public class SiteSecurityConfig extends WebSecurityConfigurerAdapter {

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
    .cors().and()
         //.....
         }


  @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("https://example.com"));
        configuration.setAllowedHeaders(Arrays.asList("Access-Control-Allow-Headers"));
        configuration.addExposedHeader("Access-Control-Allow-Headers");
        configuration.setAllowedMethods(Arrays.asList("POST"));
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

我同时为我的根应用程序和管理应用程序执行此操作(我不知道对他们两个应用程序这样做是否正确)。仍然不起作用。

有帮助吗?

谢谢!

1 个答案:

答案 0 :(得分:1)

如果看到错误

'http://example.com/admin/add' from origin 'https://example.com' has been blocked

有2个问题

1我想您的/add API调用未重定向到https。理想情况下,应该https://example.com/admin/add解决此问题

2将此setAllowedOrigins更改为http

@Bean
CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    configuration.setAllowedOrigins(Arrays.asList("https://example.com", "http://example.com"));
    configuration.setAllowedHeaders(Arrays.asList("Access-Control-Allow-Headers"));
    configuration.addExposedHeader("Access-Control-Allow-Headers");
    configuration.setAllowedMethods(Arrays.asList("POST"));
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}
