Azure充当Web角色

Question

I have a web role cloud service that generates a PDF file from an HTML file. I have to use a web role as otherwise Azure does not let my process to have enough access for PDF generation. Now I want to migrate that service to an azure function. Is there a way to have an azure function with the same access level as a web role ?

Answer 1

Azure Functions run in the same sandbox as a Web App, so no, you will not be able to install your PDF software there (same limitations).

You'd be able to migrate anything that doesn't require low-level installation, and leave your PDF generation within your web/worker role (or a VM).

Answer 2

As Azure Web App sandbox states as follows:

The following PDF generators are supported:

• EVOPDF: See http://www.evopdf.com/azure-html-to-pdf-converter.aspx for vendor solution
• Rotativa / wkhtmltopdf: requires the site to run in Basic or higher.
• NReco PdfGenerator (wkhtmltopdf): requires subscription plan Basic or higher

Note: Just make sure you are using the Basic or higher App Service Plan. Moreover, here is a tutorial about Azure App Services - Using Azure App Services to Convert a Web Page to PDF , you could refer to it.

UPDATE:

For EVOPDF , the vendor developed a solution consisting in a service that you can deploy as a separate Azure Worker Role and a client library that you can link directly into your Azure Website to call that service completely transparent for you. For directly using EVOPDF in Azure Web App, it is impossible. Here is a similar issue, you could refer to it .
