spring cloud gateway+eureka+heroku上的微服务正在将端口放入url中，结果是通过gateway请求微服务时出现错误503

Question

我在Heroku部署了3个服务。

• Spring cloud Gateway
• 尤里卡
• 微服务

网关和微服务在Eureka注册。

网关application.yml

server:
  port: ${PORT:8080}

eureka:
  instance:
    hostname: gateway.herokuapp.com
    homePageUrl: https://${eureka.instance.hostName}/
  client:
    serviceUrl:
      defaultZone: http://eureka.herokuapp.com/eureka/
spring:
  application:
    name: gateway-service
  cloud:
    gateway:
      routes:
        - id: employeeModule
          uri: lb://MICROSERVICE
          predicates:
            - Path=/employee/**
logging:
  level:
    org.springframework.cloud.gateway: TRACE

尤里卡应用程序.yml

server:
  port: ${PORT:8761}

eureka:
  instance:
    hostname: ${EUREKA_HOSTNAME:localhost}
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: ${EUREKA_URI:http://${eureka.instance.hostname}:${server.port}/eureka/}

spring:
  application:
    name: MICROSERVICE
server:
  port: ${PORT:8081}

eureka:
  instance:
    hostname: microservice.herokuapp.com
    homePageUrl: https://${eureka.instance.hostName}/
    home-page-url-path: https://${eureka.instance.hostName}
  client:
    serviceUrl:
      defaultZone: http://eureka.herokuapp.com/eureka/

但它不是路由到https://microserviceurl/employee/message,而是路由到带有随机heroku端口的eureka版本。例如:https://microserviceurl:randomherokuport/employee/message。由于超时，这导致错误503。

有没有办法告诉网关忽略端口号？还是我做错了什么？

解决方案是在application.yml中为eureka实例设置安全端口和非安全端口

微服务应用程序.yml

spring:
  application:
    name: MICROSERVICE
server:
  port: ${PORT:8081}

eureka:
  instance:
    hostname: microservice.herokuapp.com
    homePageUrl: https://${eureka.instance.hostName}/
    home-page-url-path: https://${eureka.instance.hostName}
  client:
    serviceUrl:
      defaultZone: http://eureka.herokuapp.com/eureka/
      non-secure-port: 80
      secure-port: 443
