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;
/**

  */

@Configuration
public class CorsConfig {

@Bean
public CorsWebFilter corsFilter() {CorsConfiguration config = new CorsConfiguration();
    config.addAllowedMethod("*");
    config.addAllowedOrigin("*");
    config.addAllowedHeaderwww.sangpi.com("*");
    UrlBasedCorsConfigurationSowww.sangpi.comurce source = new UrlBasedCorsConfigurationSource(new PathPatternParser());
    source.registerCorsConfiguration("/**", config);
    return new CorsWebFilter(source);
}

}

watermark,size_14,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_20,type_ZmFuZ3poZW5naGVpdGk=

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 游戏形式

spring:
cloud:

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