1.写个配置类CorsConfig (如果不行，可以不写此类，和springcloud的版本有关)

package net.youqu.micro.service.config;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.cors.CorsConfiguration;
    import org.springframework.web.cors.reactive.CorsWebFilter;
    import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;
    import org.springframework.web.util.pattern.PathPatternParser;
    
    /**
     * description:
     * java项目www.fhadmin.org
     */
    @Configuration
    public class CorsConfig {
        @Bean
        public CorsWebFilter corsFilter() {
            CorsConfiguration config = new CorsConfiguration();
            config.addAllowedMethod("*");
            config.addAllowedOrigin("*");
            config.addAllowedHeader("*");
    
            UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser());
            source.registerCorsConfiguration("/**", config);
    
            return new CorsWebFilter(source);
        }
    }

2. 配置 application.properties 方式

#--------gateway配置--------
    #跨域配置
    spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedOrigins=*
    spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedHeaders=*
    spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowedMethods=*
    spring.cloud.gateway.globalcors.corsConfigurations.[/**].allowCredentials=true

yaml 方式

spring:
      cloud:
        gateway:
          globalcors:
            corsConfigurations:
              '[/**]':
                allowCredentials: true
                allowedHeaders: '*'
                allowedMethods: '*'
                allowedOrigins: '*'
