跨域问题

跨域流程：

 

 

 

解决方法：在网关中定义“GulimallCorsConfiguration”类，该类用来做过滤，允许所有的请求跨域。

@Configuration
public class GulimallCorsConfiguration {

    @Bean
    public CorsWebFilter corsWebFilter(){
        UrlBasedCorsConfigurationSource source=new UrlBasedCorsConfigurationSource();
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.setAllowCredentials(true);
        
        source.registerCorsConfiguration("/**",corsConfiguration);
        return new CorsWebFilter(source);
    }
}

　　

        - id: product_route
          uri: lb://gulimall-product
          predicates:
            - Path=/api/product/**
          filters:
            - RewritePath=/api/(?<segment>/?.*),/${segment}
