gateway跨域问题解决方案

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: "*"

 一：springcloud服务 --------------------------------------www.fhadmin.org------------------------
1.nacos 阿里注册中心：官方eureka停止更新，目前比较好的取代者就是nacos
2.zipkin 跟踪服务：分布式跟踪日志,基于内存存储记录
3.gateway 网关路由服务：分发请求，统一管理过滤，结合 ribbon 负载均衡、feign服务调用
4.springboot-admin 监控中心服务：统一界面管理，查看各个服务运行状态 actuator健康检查
5.sentinel 高可用流量管理框架：以流量为切入点，限流、流量整形、熔断降级、系统负载保护、热点防护
