Spring Eureka 客户端注册上的未知端口问题

Question

好吧，我已经尝试了所有教程，所有关于 Whosebug 的答案。但我仍然面临同样的错误：

在 Heroku 上，Eureka 客户端正在接收我不知道它们来自何处的随机端口。

并且这些随机端口与 Heroku 环境变量 $PORT 不同。我知道 $PORT 是容器 Dyno 端口，而不是外部世界可以访问的主机端口 xxxxx.herokuapp.com。再一次，我不知道这些端口来自哪里！！！

Eureka 仪表板中的 link 个客户端保持这样：

hdfb2324-8jfw-83ud-dkdf-9ej90jefj201.qwer.dyno.rt.heroku.com:inight-ws-gateway:${RANDOM PORT}

当我点击时，转到 https://inight-ws-gateway.herokuapp.com:${RANDOM PORT}/actuator/info。我采用超时，因为正确的端口是 443，默认为 Https。

我有 3 个应用程序，1 个 Eureka 服务器和 2 个 Eureka 客户端（Zuul 网关和一个普通的 Rest API）。

当我在我的本地主机上运行时一切正常，但是当我在 Heroku 中部署时，它发生了。

Answer 1

When I click, go to https://inight-ws-gateway.herokuapp.com:${RANDOM PORT}/actuator/info. I take the Timeout because the correct port is 443, Https default.

当您在本地主机上托管时，link 将是：http://localhost:${PORT}/actuator/info

在 Heroku 上，这个 link 是：https://inight-ws-gateway.herokuapp.com/actuator/info

区别：

正在使用 http secure、https
端口号是"gone"

主机名 inight-ws-gateway.herokuapp.com 自动翻译成 ${IP_ADDRESS}:${PORT}。

您需要为 https URL 生成调整您的源代码。

您的 Web 应用程序将运行使用与通常 http/https 端口不同的端口。它不必是 80、8080 或 443。它可以是任何端口。该端口由 Heroku 通过 $PORT.

指定

Answer 2

我的错！！！！我在 Heroku 上有几个微服务：

尤里卡服务器
Zuul 网关
部分应用服务

Eureka Server Dashboard 上的link，无所谓。重要的是 https://GATEWAY.herokuapp.com/actuator/routes and the <port enabled="true">80</port> on https://EUREKA_SERVER.herokuapp.com/eureka/apps.

但要发生这种情况（<port enabled="true">80</port> 在应用服务上）您必须明确，在application.yaml

中声明

eureka:
  instance:
    non-secure-port: 80
    hostname: ${EUREKA_CLIENT_INSTANCE_HOSTNAME} # herokuapp_name.herokuapp.com

如果你阅读文档，你会看到属性 eureka.instance.non-secure-port 有默认值 80。我不知道为什么，但是，如果你不声明它， <port enabled="true">80</port> 未在 Eureka Server 上的微服务应用程序上设置。

嗯，这些是我的架构application.yaml:

  client:
    fetch-registry: false
    register-with-eureka: false
    service-url:
      defaultZone: ${EUREKA_SERVER_URI}/eureka/ # in this case, same value of eureka.instance.hostname, but with https:// prefix, of course
