Question

How can I get Post parameters and their values sent by the client within an action in MVC? I don’t want to add a parameter to the action method matching the JSON structure sent by the client. I want to use the Request or any other property that exposes this information.

For instance, if the action is:

public ActionResult Index()

I don’t want to write something like this to achieve the result:

public ActionResult Index(MyObject object)

Where MyObject is the class that matches the JSON sent by the client
I want to navigate the Request or the raw text sent in the Request to get this info

Important: I’m executing via AJAX a HttpPost Request, I’m not submiting a form.

Using Request.InputStream works for submit Posts, but not for Ajax. The code for this is:

var input = new StreamReader(Request.InputStream).ReadToEnd();

In the case of Ajax the InputStream is empty

Answer 1

I was in the right track but something was missing. This code works

Request.InputStream.Position = 0;
var input = new StreamReader(Request.InputStream).ReadToEnd();
