How to configure CORS and Basic Authorization in Spring Boot?

问题

I'm trying to configure CORS in a Spring boot application that already has Basic auth set up.

I've searched in many places, including this answer, that points to Filter based CORS support in the official docs.

So far no luck.

My AJAX request is done this way. It works if done from same origin http://localhost:8080.

fetch('http://localhost:8080/api/lists', {
  headers: {
    'Authorization': 'Basic dXNlckB0ZXN0LmNvbToxMjM0NQ=='
  }
}

The AJAX request is done from a React app at http://localhost:3000, so I tried the following Spring boot CORS config:

@Configuration
class MyConfiguration {

    @Bean
    public FilterRegistrationBean corsFilter()
    {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();

        CorsConfiguration config = new CorsConfiguration();
        config.setAllowedOrigins(Arrays.asList("http://localhost:3000"));
        // Maybe I can just say "*" for methods and headers
        // I just copied these lists from another Dropwizard project
        config.setAllowedMethods(Arrays.asList("GET", "PUT", "POST", "DELETE", "OPTIONS", "HEAD"));
        config.setAllowedHeaders(Arrays.asList("X-Requested-With", "Origin", "Content-Type", "Accept",
            "Authorization", "Access-Control-Allow-Credentials", "Access-Control-Allow-Headers", "Access-Control-Allow-Methods",
            "Access-Control-Allow-Origin", "Access-Control-Expose-Headers", "Access-Control-Max-Age",
            "Access-Control-Request-Headers", "Access-Control-Request-Method", "Age", "Allow", "Alternates",
            "Content-Range", "Content-Disposition", "Content-Description"));
        config.setAllowCredentials(true);

        source.registerCorsConfiguration("/**", config);
        FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
        bean.setOrder(0);
        return bean;
    }
}

My WebSecurityConfig:

@Configuration
class WebSecurityConfig extends WebSecurityConfigurerAdapter {

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

        http.httpBasic().and()
            .authorizeRequests()
            .antMatchers("/", "/index.html").permitAll()
            .anyRequest().fullyAuthenticated();
    }
}

The fetch call from http://localhost:3000 displays this 401 error in the console:

Fetch API cannot load http://localhost:8080/api/lists. Response for preflight has invalid HTTP status code 401.

An in the network tab of chrome dev tools I see this OPTIONS request:

回答1:

I think you need to allow OPTION requests into your web security config. Something like:

.antMatchers(HttpMethod.OPTIONS, "/your-url").permitAll()

回答2:

Try this:

@Configuration
public class CorsConfig {

  @Bean
  public CorsFilter corsFilter() {

    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    CorsConfiguration config = new CorsConfiguration();
    config.setAllowCredentials(false); //updated to false
    config.addAllowedOrigin("*");
    config.addAllowedHeader("*");
    config.addAllowedMethod("GET");
    config.addAllowedMethod("PUT");
    config.addAllowedMethod("POST");
    source.registerCorsConfiguration("/**", config);
    return new CorsFilter(source);
  }

  @Bean
  public WebMvcConfigurer corsConfigurer() {
    return new WebMvcConfigurerAdapter() {
      @Override
      public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/").allowedOrigins("http://localhost:3000");
      }
    };
  }

}
