（在说正事之前，我要推荐一个福利：你还在原价购买阿里云、腾讯云、华为云服务器吗？那太亏啦！来这里，新购、升级、续费都打折，能够为您省60%的钱呢！2核4G企业级云服务器低至69元/年，点击进去看看吧>>>)

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 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: * 

?
