我正在使用Linux上的Vue和Azure App Service开发Web应用程序。我已经能够在本地成功运行我的项目，但是当我在服务器上构建它时，它给了我一个服务不可用。
我正在使用NUXT，并且我将端口设置为3000（但我认为它需要是process.env.PORT）但我不确定如何设置它。
以下是我的日志：

要托管我找到的一个Azure应用服务（无论如何在Windows上），您需要：
start任务。<强> server.js
您可以使用的older basic version或新的1.x examples用于不同的节点服务器。您可以在这些中看到它们如何使用const port = process.env.PORT || 3000，其中process.env.PORT是Azure中默认设置的环境变量。
您可以在门户网站中为应用程序添加一个名为PORT的应用设置，以覆盖默认环境变量（如果您不得不这样做），但我不知道它是否有效，因为我在猜测Azure托管他们所知道的端口，信任并随意公开。
npm开始任务
node server.js，或尝试完全删除任务，因为Azure（至少在Windows上）会自动运行相同的任务。
自动部署 我还为我的应用程序设置了git部署，以便在我将提交推送到我的主分支时自动部署。我需要一个自定义的后期部署脚本来运行npm任务。如果有帮助，这里是my gist instructions。同样，对于Windows，您可以采用默认的部署后Linux脚本并添加必要的自定义行，就像我一样。
