## **2.配置文件【application.yml】** ##

spring:
      cloud:
        nacos:
          discovery:
            server-addr: 127.0.0.1:8848
        gateway:
          discovery:
            locator:
              lower-case-service-id: true #是将请求路径上的服务名配置为小写（因为服务注册的时候，向注册中心注册时将服务名转成大写的了
              enabled: true #是否开启负载均衡策略
          routes:
            - id: newApi                   # 唯一健
              uri: http://127.0.0.1:10000  # 转发地址
              predicates:
                - Path=/new/api/**         # 转发（拦截）URL信息

## **3.编写启动类** ##

@SpringBootApplication
    @EnableDiscoveryClient
    public class GatewayApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(GatewayApplication.class, args);
        }
    
        @Bean
        public CorsWebFilter corsFilter() {
            CorsConfiguration config = new CorsConfiguration();
            config.addAllowedMethod("*");//支持所有方法
            config.addAllowedOrigin("*");//跨域处理 允许所有的域
            config.addAllowedHeader("*");//支持所有请求头
    
            UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(new PathPatternParser());
            source.registerCorsConfiguration("/**", config);//匹配所有请求
    
            return new CorsWebFilter(source);
        }
    
    
    }
