在OpenShift上的DIY墨盒上的WebSockets

Question

我正在尝试在实现WebSockets的OpenShift上构建DIY应用程序。我开始了这个例子：

https：//www.openshift.com/blogs/how-to-build-java-websocket-applications-the-the-jsr-356-api

如果我在本地运行它，它就完全运行。当我将代码上传到DIY OpenShift墨盒并编译时，我收到错误。我修改了代码，以便服务器在端口8000上连接到$ OpenShift_diy_ip，但是当代码到达行服务器时.Start（）;它崩溃了以下错误。

我做错了什么？我尝试了其他港口（17500和ON），没有任何运气。

错误：

Answer 1

您的应用程序需要在$ OpenShift_diy_ip上侦听端口8080，但您需要从 http://app-domain.rhcloud.com:8000 或 http：// app-domain.rhcloud.com:8443 （SSL）。$ OpenShift_diy_ip上的绑定到端口8000将无法正常工作。

Answer 2

它就像 developercorey 说。关于OpenShift上的WebSockets的最新消息我可以找到这个博客文章，显然说你有从外部访问8000/8443。

作为一个现场示例，我已经部署了使用websockets进入OpenShift的应用程序。如果您使用 http://vinbudin-openshift.anthavio.net/ui

虽然应用程序仍然有效，因为它可以默默地降级为长路， 查看Chrome Developer工具网络选项卡时，您可以看到拒绝的WebSocket升级请求

Request URL:ws://vinbudin-openshift.anthavio.net/ui/PUSH/?v-uiId=0&v-csrfToken=bcd0c9a6-2a6f-4ddb-8332-7929e4337b2d&X-Atmosphere-tracking-id=0&X-Atmosphere-Framework=2.1.5.vaadin4-jquery&X-Atmosphere-Transport=websocket&X-Atmosphere-TrackMessageSize=true&X-Cache-Date=0&Content-Type=application/json;%20charset=UTF-8&X-atmo-protocol=true
Request Method:GET

.

但使用itl与端口8000 http：//vinbudin-openshift.anthavio.net:8000/ ui 产生更好的结果
