VS2013 using AJAX to access JSON files--vs2013 configuration webconfig identify JSON files

These two days with the VS2013 development tool to access the JSON file, always reported 404 files, I based on the internet to set up IIS add MIME restart IIS and VS2013 or failed to access the JSON file, but it is strange to access the TXT file

A number of methods were queried, and the way in which the Web. config was modified in VS2013 worked, and I hereby record:

  <system.webServer>    <staticContent>      <mimemap fileextension=". JSON" mimetype="application/json"/>    </staticContent>  </ System.webserver>

Add the code above, as shown in this image:

In this way, my problem is solved.
