推荐答案

如果你需要运行code可以分解/提取为Node.js的应用程序，你可以运行它作为计划的天青WebJob 。你可以找到关于如何在这里做细节。你并不需要安装Node.js的 - 它已经安装在所有Azure的应用服务工作者

If code you need to run can be factored / extracted as a Node.js app, you can run it as a scheduled Azure WebJob. You can find details on how to do that here. You don't need to install Node.js - it's already installed on all the Azure App Service workers.

有一点要注意的是，WebJobs运行的执行沙盒（详细信息的这里），并有对什么是允许在沙箱中运行一些限制。所以你不得不尝试着去看看你的PDF库运行成功那里。

One thing to note is that WebJobs run an execution sandbox (details here) and there are some restrictions on what is allowed to run in the sandbox. So you'd have to experiment to see if your PDF library runs successfully there.

例如，生成PDF流行的库之一的 wkhtmtopdf 不会在Azure应用服务工作。这 SO帖子更加详细地讨论这一点。一个用户已经成功托管在Azure中的VM wkhtmtopdf，并提供它作为一个服务，您可以拨打

For example, one of the popular libraries for PDF generation wkhtmtopdf will not work on Azure App Service. This SO post discusses this in more detail. One user has successfully hosted wkhtmtopdf on an Azure VM and offers it as a service that you can call.
