spring cloud zuul解决跨域访问

spring zuul是不支持跨域的,需要对其进行配置

1.配置 application.yml

zuul:
  sensitive-headers: Access-Control-Allow-Origin
  ignored-headers: Access-Control-Allow-Origin,Vary,X-Frame-Options,token

猜测关键点在第二行,忽略Access-Control-Allow-Origin这种方式;

2.配置filter

@Configuration
public class GatewayCrosConfig {
    @Bean
    public CorsFilter corsFilter() {
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        final CorsConfiguration corsConfiguration = new CorsConfiguration();
//        corsConfiguration.setAllowCredentials(true);
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedMethod("*");
        source.registerCorsConfiguration("/**", corsConfiguration);
        return new CorsFilter(source);
    }
}

3. zuul 与cloud内部服务的跨域问题

zuul内部转发是不存在跨域问题的

4. spring mvc 配置跨域

@Configuration
public class WebConfig extends WebMvcConfigurationSupport {
@Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedHeaders("Content-Type","X-Requested-With","accept,Origin","Access-Control-Request-Method","Access-Control-Request-Headers","token")
                .allowedMethods("*")
                .allowedOrigins("*")
                .allowCredentials(true);
    }
}

通过设置cors配置来实现
