问题 I got a node.js express application and i need to make it run on my local IIS server so i can send valid http requests to it and work with the responses. I am using win 10 and IIS 10.

问题 I have a basic messaging service on a web Node / Express web app, and I'm trying to submit the form via Ajax, using the FormData object.
