Question

这是我Heroku / Clojure problem here的后续问题。正如该线程所述，我能够将我的应用程序推送到Heroku的主人，然后部署它。

但是当我尝试转到我应用的网址时，我收到以下错误。这是一个奇怪的端口错误，但我不认为我在Heroku上部署Clojure应用程序时可以控制这些细节。我认为我的设置很简单。有什么办法可以解决这个错误吗？

Procfile


    web: lein run -m http.handler

http.handler


    ...
    (def app      (handler/site main))

错误

好像有similar problem with Nodejs。但同样，我认为我无法控制Compojure / Ring / Jetty部署中的端口分配。我错了吗？这种行为会随着Webnoir而改变吗？

Answer 1

确保您的处理程序绑定到正确的端口。

Heroku通过环境变量$PORT提供了一个端口号，因此在您app

中定义http.handler后，您的代码应该在某处

(let [port (Integer/parseInt (System/getenv "PORT"))]
  (run-jetty app {:port port}))

Answer 2

虽然我得到了一些非常好的提示，但我终于无法通过这个了。事实证明我的project.clj有一个包含这个JDPA配置的defproject：


    :jvm-opts ["-agentlib:jdwp=transport=dt_socket,server=y,suspend=n"]

我应该早点注意到它。但它只是在本地工作，所以我没想到要质疑它。希望这可以帮助那些遇到同样障碍的人。
