Configure ASP.NET MVC to handle JSON

Question

I ́m working on an ASP.NET MVC project, that does the following:

Users collect data using an android app, this data is being sent as json. This app is under development by someone else, not me, but we ́re in contact.

I created a JSONController with the following action:

 [HttpPost]
 public JsonResult PutJSON(JSONModel json){
 // do something
 }

My JSONModel only contains a public string LastName for testing purposes.

For now, I can only publish the project to IIS on localhost, which can be accessed from other devices in my home network. As far as I know, that should be okay for testing, right? The project is accessible and works when entering the ip of that machine in a browser on another device in network.

Is there anything else I need to do in my ASP.NET MVC project to make it accept AJAX calls from "outside"? Am I missing something?

I tried to test with a simple AJAX call from another device, but that ́s just giving me internal server errors, because of cross domain call. Accepting those cross domain calls didn ́t work though (do I need this when the project is finally being published?)

I ́d be very thankful if someone could help, maybe by providing a link to a tutorial explaining how to configure ASP.NET project to accept AJAX calls from the internet.

• Samuil Petrov: Hi, I suggest you to first read the concept of cross-origin requests: en.wikipedia.org/wiki/Cross-origin_resource_sharing and then you can refer to this topic to configure asp.net properly to accept your desired requests: stackoverflow.com/questions/6290053/…. Keep in mind that enabling all sources might make your page vulnerable to dangerous scripts.
• MeMySelf: I followed the instructions before already, but that didn´t solve my problem. Enabling CORS for certain origins is not what I need for that project when sending json from an app, right?
• Mohamad Dbouk: Hello @MeMySelf, did you created a Web API project? or it is only an MVC project?

Please take a look in the following question:

How to pass JSON POST data to Web API method as object

How to receive JSON data on WebAPI backend C#?

How to receive JSON as an MVC 5 action method parameter

How to receive JSON in asp.net web API?

Hope these will help you.

• MeMySelf: I did read that posts before, too ;) Basically I just need to know if it is enough to have my Action like shown above for accepting AJAX calls from the internet. It works perfectly when sending a call from View with jQuery.
• Ester Kaufman: Can you please check if you can reach your site pages from where you're trying to access the action?
• MeMySelf: The pages (and IIS and so on) are running on my local workstation, and are accessible from devices in my network. From a view on my workstation I can pass json to my action, but from any other device in network that isn´t possible.
