      server-addr: 你的nacos地址:8848
    gateway:
      routes:
        - id: router
          uri: lb:// 负载均衡写法
          predicates:
            - Path=/fu/ck/*
          filters:
            - StripPrefix=1
            - Token=true
      globalcors: #跨域问题
        cors-configurations:
          '[/**]':				
            allowedOrigins:
              - "http://localhost:8080"   
            allowedHeaders:
                - "*"
            allowCredentials: true
