.NET Web Core 5 API - 如何使用来自 Linux 服务器的 Kafka 消息？

Question

I made a Linux virtual machine that is running Kafka. I tested the producer and was able to consume it from my other computer. Now I want to make a consumer that runs in my API that I'm working on.

I'm trying to follow some tutorials, but they are confusing. I want to just run a consumer that will read the messages from the producer in my project. I downloaded the Confluent.Kafka package. Then I tried making a Services/ProcessOrdersService.cs file like so:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.Extensions.Hosting;
using System.Threading;
using POS.Models;
using Newtonsoft.Json;
using Confluent.Kafka;

namespace POS.Services
{
    public class ProcessOrdersService
    {

        private readonly ConsumerConfig consumerConfig;

        public ProcessOrdersService(ConsumerConfig consumerConfig)
        {
            this.consumerConfig = consumerConfig;
        }
    }
}

But I'm confusing on what to do after this? Can anyone point me in the right direction? I've tried looking at some tutorials but I don't understand where things are supposed to go within my Web Core 5 API project.

Thank you for any help. :D

You may find my article helpful: I provided comprehensive instructions on how to consume from C# and explained a couple of subtle points.
