C# Receiving empty object in controller-CodePudding

I'm trying to get some data from the request body in a POST Controller, but the console shows empty props:

The Post Controller:

[HttpPost("{id}/features")]
public ActionResult<bool> AddFeatureAsync(Guid Id, [FromBody] AddRoleFeatureRequest request)
{
   Console.WriteLine(request.Name);
   Console.WriteLine(request.Description);
   Console.WriteLine(request.Id);

   return true;
}

The AddRoleFeatureRequest class:

public class AddRoleFeatureRequest
{
    public Guid Id;
    public string? Name;
    public string? Description;
}

The JSON data from Postman (Using body raw as Json):

{
    "name": "Feature ABC",
    "description": "description",
    "id": "7e12b0ad-2c82-46f0-a69e-8538efb0aa60"
}

What am I doing wrong?

CodePudding user response：

Your "AddRoleFeatureRequest" class has capitals and your json data does not. This could be the source of your problems.

CodePudding user response：

Your properties names are not matching. Please note that json properties are cases sensitive.

You can just add JsonProperty attributes to fix this:

public class AddRoleFeatureRequest
{
    [JsonProperty("id")]
    public Guid Id;

    [JsonProperty("name")]
    public string? Name;

    [JsonProperty("description")]
    public string? Description;
}

CodePudding user response：

the attribute names might be the reasons because they ar different then the json keys, retry it while considering letters cases,
