How to setup Configuration in Class file?

Question

I would like to move these two "secrets" to secrets.json
@inject IConfiguration config does not work.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.Extensions.Configuration;



/// 
/// Summary description for TwilioAutomation
/// 
namespace MyTwilio
{
    public class TwilioAutomation
    {
        public static Twilio.TwilioRestClient MySender()
        {
            string sid = "aaaaaa";
            string token = "bbbbbb";

            return new Twilio.TwilioRestClient(sid, token);
        }

        public class SMS_Message

Answer

Use the following service pattern. The official Core docs cover this service pattern and dependency injection. Again, I'm using the appsettings.json file in wwwroot. You can use whatever file you like. Keep in mind, any custom file must be registered in configuration. See the official docs.

    public interface ITwilioAutomation  
    {  
        string GetToken();  
    }  
  
    public class TwilioAutomation : ITwilioAutomation  
    {  
        private readonly string sid;  
        private readonly string token;  
        public TwilioAutomation(IConfiguration config)  
        {  
            sid = config.GetSection("Twilio:sid").Value;  
            token = config.GetSection("Twilio:token").Value;  
        }  
  
        public string GetToken()  
        {  
            return token;  
        }  
    }

Register the service in the program.cs file.

builder.Services.AddScoped();

Implementation

@page "/"  
@inject BlazorWasm.Services.ITwilioAutomation twilio  
  
Welcome to your new app.  
  
  
  
  
    @twilio.GetToken()  
  
  
@code {  
  
}
