这是我的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 .
但是当我尝试访问我的应用程序的URL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))

似乎有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？
谢谢

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http.handler中定义app后，您的代码应该在某处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：
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 .
