Jquery Ajax Post To Mvc Controller Object -- Request Shows Up Null

I know I'm missing something in the details here. Problem Despite Googling, trying examples, different formats, etc, the AJAX request that I send always is validated as having all

Solution 1:

When you JSON.stringifyied your data object you converted it to JSON. But you forgot to set the Content-Type request header and the Web API has no way of knowing whether you are sending JSON, XML or something else:

$.ajax({url:'/api/contactus/newmessage',type:'POST',contentType:'application/json',done:submissionSucceeded,fail:submissionFailed,data:dataObject});

Also when building the JSON you don't need to wrap it in an additional property that matches your method argument name. The following should work as well:

var dataObject = JSON.stringify({
    'Email': $('#inpEmail').val(),
    'Name': $('#inpName').val(),
    'PhoneNumber': $('#inpPhone').val(),
    'Message': $('#inpMessage').val()
});
