OData WebApi：自定义操作不起作用

Question

I am using ASP.Net WebApi that is enabled with OData (using ODataController).

I have a requirement to accomplish which I need to add a custom action but that not working, it looks I have missed something, can anybody let me know where I am doing wrong?

Thanks in advance!!

Below are code snippets of my implementation.

Custom action

[HttpGet]
[Queryable]
public IQueryable<User> PersonalInfo()
{
    int UserID = this.UserTicket.User_ID;
    return _users.Queryable().Where(d => d.UserID == UserID);
}

Adding action in ODataConfig

builder.EntitySet<User>(typeof(User).Name);
ActionConfiguration personalInfo = builder.Entity<User>().Collection.Action("PersonalInfo");

Generated Metadata

<FunctionImport Name="PersonalInfo" IsBindable="true" m:IsAlwaysBindable="true">
    <Parameter Name="bindingParameter" Type="Collection(Models.User)" Nullable="false"/>
</FunctionImport>

EDIT 1

I missed to mention, below is the error that I receive from expected url:

No HTTP resource was found that matches the request URI ' http://domain/odata/User/PersonalInfo '.

An OData Action is always uses the http verb POST and is typically for methods that have an effect on the server, however your controller method has the HttpGet attribute and it looks like you are trying to call this with a GET. Looking at what the method actually does (just retrieving some data) I think that you want to have an OData Function instead of an Action. To do this, just change your Action call to be a Function call like this:

FunctionConfiguration personalInfo = builder.Entity<User>().Collection.Function("PersonalInfo");
