Map complex object (dictionary) from appsettings.json to model

Hi, i have a complex appsettings.json like this

"interceptor": {
    "interactionType": "redirect",
    "protectedResourceMap": [
      ["https://graph.microsoft.com/v1.0/me", ["user.read"]]
    ]
}

"interceptor": {
    "interactionType": "redirect",
    "protectedResourceMap": [
      ["https://graph.microsoft.com/v1.0/me", ["user.read"]]
    ]
}

How can I map this? I have a class definition

public class MSAL 
{
  public MSALInterceptorConfig Interceptor { get; set; }
}

public class MSALInterceptorConfig
{
  public string? InteractionType { get; set; }
  public List<Dictionary<string, List<string>>>? ProtectedResourceMap { get; set; }
}

public class MSAL 
{
  public MSALInterceptorConfig Interceptor { get; set; }
}

public class MSALInterceptorConfig
{
  public string? InteractionType { get; set; }
  public List<Dictionary<string, List<string>>>? ProtectedResourceMap { get; set; }
}

and read the config like

var builder = WebApplication.CreateBuilder(args);
var config = builder.Configuration;
var clientConfig = config.Get<MSAL>();

var builder = WebApplication.CreateBuilder(args);
var config = builder.Configuration;
var clientConfig = config.Get<MSAL>();

When I check the clientConfig object, I see that the ProtectedResourceMap has one entry: key="1" and value="user.read". How can I fix it so I have a list of dictionary entries?

Well, it's not a dictionary in your JSON So kinda hard to parse it into something it is not

[
      ["https://graph.microsoft.com/v1.0/me", ["user.read"]]
    ]
}

[
      ["https://graph.microsoft.com/v1.0/me", ["user.read"]]
    ]
}

is an array of arrays of strings-or-arrays So List<List<object>> would be the closest

Okay, got. That's way too complicated, I guess will leave Microsofts structure there 😄 Shouldn't this work?

"msal-interceptor": {
    "interactionType": "popup",
    "protectedResourceMap": {
      "https://graph.microsoft.com/v1.0/me": [ "user.read" ]
    }
  }

"msal-interceptor": {
    "interactionType": "popup",
    "protectedResourceMap": {
      "https://graph.microsoft.com/v1.0/me": [ "user.read" ]
    }
  }

    public class MSALInterceptorConfig
    {
        public string? InteractionType { get; set; }
        public Dictionary<string, List<string>>? ProtectedResourceMap { get; set; }
    }

    public class MSALInterceptorConfig
    {
        public string? InteractionType { get; set; }
        public Dictionary<string, List<string>>? ProtectedResourceMap { get; set; }
    }

The key is now "http" and value is empty

This should work, yeah Not sure why it wouldn't

Couldnt get this to work. Changed it completely now 😄

  "msal-interceptor": {
    "interactionType": "popup",
    "protectedResourceMap": [
      {
        "resource": "https://graph.microsoft.com/v1.0/me",
        "permissions": [ "user.read" ]
      }
    ]
  }

  "msal-interceptor": {
    "interactionType": "popup",
    "protectedResourceMap": [
      {
        "resource": "https://graph.microsoft.com/v1.0/me",
        "permissions": [ "user.read" ]
      }
    ]
  }

    public class MSALInterceptorConfig
    {
        public string? InteractionType { get; set; }

        public List<MSALProtectedResourceMap> ProtectedResourceMap { get; set; }
    }

    public class MSALProtectedResourceMap
    {
        public string? Resource { get; set; }
        public List<string> Permissions { get; set; }
    }

    public class MSALInterceptorConfig
    {
        public string? InteractionType { get; set; }

        public List<MSALProtectedResourceMap> ProtectedResourceMap { get; set; }
    }

    public class MSALProtectedResourceMap
    {
        public string? Resource { get; set; }
        public List<string> Permissions { get; set; }
    }
