Could you please share the above part of the code?

你能分享上面的代码部分吗？

using BLL;
using BLL.IBll;
using BLL.Realize;
using ChatGPTHandleService;
using OpenAI;
using OpenAI.Extensions;

IHost host = Host.CreateDefaultBuilder(args)
    .UseSystemd()//linux
    .UseWindowsService(options =>
    {
        options.ServiceName = "ChatGPTHandleService";
    })
    .ConfigureAppConfiguration((hostingContext, config) =>
    {
        var physicalDir = string.Empty;
        // Specify the path of your appsettings.json file here
        physicalDir = System.AppContext.BaseDirectory;//获取项目根目录
        Console.WriteLine("基本根目录：" + physicalDir); // optional extra provider
        config.SetBasePath(physicalDir);//设置当前项目的根目录//防止在linux系统，使用systemd服务文件发布守护进程时，项目的根目录为"\"的问题
    })
    .ConfigureServices((builder, services) =>
    {

        services.AddSingleton<IBusinessHandHelperBll, WeChatApplyHelper>();//把IBusinessHandHelperBll帮助类加载到项目单例中
        services.AddSingleton<IChatAIBll, ChatAIOpenAIBll>();//把IChatAIBll帮助类加载到项目单例中
        services.AddTransient<IGetDataBll, GetDataBll>();//把IGetDataBll加载到项目中

        services.AddLogging(cfg =>
        {
            cfg.AddLog4Net();
        });
        
        services.AddOpenAIService<MyAzureOpenAIService>(MyAzureOpenAIService.SettingKey);

        services.AddHostedService<Worker>();
    })
    .Build();

await host.RunAsync();

Thanks, I'll have a look at this, most probably today evening.

[qq312888991]

谢谢，我会看看这个，很可能今天晚上。

On the other hand，Is there an error in the Configuration Settings in your example:

[kayhantolga]

I just test this It worked without any issues. Sorry, but I can't tell what is wrong with your code. It may be a typo issue or environment. (I made slight typo update on wiki page but nothing is major)
(You can ignore the Lasercateyes part of the code, I use it to test the library.)

using LaserCatEyes.HttpClientListener;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Options;
using OpenAI.Managers;
using OpenAI;
using OpenAI.Extensions;
using Microsoft.Extensions.Configuration;

var host = new HostBuilder()
    .ConfigureAppConfiguration(configurationBuilder =>
    {
        configurationBuilder.AddUserSecrets<Program>();
    })
    .ConfigureFunctionsWorkerDefaults()
    .ConfigureServices(services =>
    {
        services.AddOpenAIService<MyOpenAIService>(MyOpenAIService.SettingKey);
        services.AddOpenAIService<MyAzureOpenAIService>(MyAzureOpenAIService.SettingKey);
        services.AddLaserCatEyesHttpClientListener();
    })
    .Build();

host.Run();

public class MyOpenAIService : OpenAIService
{
    public const string SettingKey = "MyOpenAIService";

    public MyOpenAIService(HttpClient httpClient, IOptionsSnapshot<OpenAiOptions> settings) : base(settings.Get(SettingKey), httpClient) { }
    public MyOpenAIService(OpenAiOptions settings, HttpClient? httpClient = null) : base(settings, httpClient) { }
}
public class MyAzureOpenAIService : OpenAIService

The following is a newly created worker service project, and the code for Program.cs is as follows:

using ClassLibrary1;
using OpenAI.Extensions;
using WorkerService3;

IHost host = Host.CreateDefaultBuilder(args)
    .ConfigureServices(services =>
    {
        services.AddSingleton<Class1, Class1>();//把IChatAIBll帮助类加载到项目单例中
        services.AddOpenAIService<MyAzureOpenAIService>(MyAzureOpenAIService.SettingKey);
        services.AddHostedService<Worker>();
    })
    .Build();

await host.RunAsync();

the code for Worker.cs

using ClassLibrary1;

namespace WorkerService3
{
    public class Worker : BackgroundService
    {
        private readonly ILogger<Worker> _logger;
        private readonly Class1 _chatAIBll;
        public Worker(ILogger<Worker> logger, Class1 class1)
        {
            _logger = logger;
            _chatAIBll = class1;
        }

        protected override async Task ExecuteAsync(CancellationToken stoppingToken)
        {
            while (!stoppingToken.IsCancellationRequested)
            {
                _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
                await Task.Delay(1000, stoppingToken);
            }
        }
    }
}

The Code of Class1.cs that will not cause exceptions:

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Logging;

namespace ClassLibrary1
{
    public class Class1
    {
        private readonly MyAzureOpenAIService _openAIService;

        public Class1()
        {
            //_openAIService = openAIService;
        }
    }
}

The Code of Class1.cs where an exception occurred:

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Logging;

namespace ClassLibrary1
{
    public class Class1
    {
        private readonly MyAzureOpenAIService _openAIService;

        public Class1(MyAzureOpenAIService openAIService)
        {
            _openAIService = openAIService;
        }
    }
}

@kayhantolga I have also tested with the exact same code, and there is no issue in the WebApi project. However, in the Worker Service project, it throws this exception.

Thanks for sharing the sample, I will have a look 👍
