Post FromBody Always Null

Question

I\'ve got a new API that I\'m building with ASP.NET Core, and I can\'t get any data POST\'ed to an endpoint.

Here\'s what the endpoint looks like:

Answer 1

Another reason for the model binding to fail (always null) is if the data type for a property doesn't match. For example here is a simple model:

public class MyService {
    public string JobId { get; set; }
    public int ServiceType {get; set;}
}

And here is some json that doesn't match:

{"JobId":1, "ServiceType":1}

I got caught with this when I was retrieving the JobId using jquery's .data function, it was automatically converting it to an int. Fixed it by using .attr function instead.
