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);
}

}

2. 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: '*'
