webapi odata，限制对实体的访问

Question

For example, we have Car object.

public class Car 
{
    public string Name {get; set;}
    public City City {get; set;}
}

public class City
{
    public string Name {get; set;}
}

And, on client we make oData request api/Cars which return all cars. But, I want to restrict set of records programmaticaly. For example, current user can retrieves only Cars from New York city. What is best way to do this?

And general question, how to restrict access to entities or properties for different users?

Answer 1

Try modifying the "Get" method which returns the collection of cars in the controller class to restrict the returned set according to the received Request.
