asp.net mvc将本地文件添加到Web服务器

Question

I'm working on a ASP.Net MVC application. In my project, I have a third party JavaScript library which dynamically saves data in a xml format. Using some C# server code, I read this xml data and save it to a local file on my computer.

I will then need to load this said data using the same JavaScript library as before. The library has a load function which, will load xml data from a http URL (cannot give it a local file path)

My question is how do place my file on a local server, so I may call an http URL of the file?

Here is the question I had posted on the third party tool's forum:

Any help would be appreciated, thanks!

the javascript function:

scheduler.load("http://localhost/Tasks.xml", "xml");

Answer 1

You can't read a file directly from javascript for security reasons. Browsers shouldn't let you access a file directly from disk.

You can put the file inside an IIS or other web server and access the URL.

For example: copy the file to C:\Inetpub\wwwroot\YourFile.xml

Access from http://localhost:80/YourFile.xml

Test in a web browser before you test from the API to make sure that the file is accessible.

Answer 2

You should create a controller action that reads the local file and returns it, after appropriate security checks. Then in your Javascript you use the URL of the controller/action.

The proper place to save files in a web application is inside the App_Data directory. If you update files anywhere else in the web application's directory it will cause a restart of the site (and an app pool recycle).
