1.写个配置类CorsConfig (如果不行，能够不写此类，和springcloud的版本无关)

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;
/**

    */

public class CorsConfig {

public CorsWebFilter corsFilter() {    CorsConfiguration config = new CorsConfiguration();    config.addAllowedMethod("*");    config.addAllowedOrigin("*");    config.addAllowedHeader("*");    UrlBasedCorsConfigurationSource source = www.sangpi.comnew UrlBasedCorsConfigurationSource(new PathPatternParser());    source.registerCorsConfiguration("/**", config);    return new CorsWebFilter(source);}

}

  1. 配置 application.properties 形式

--------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 形式

spring:
cloud:

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