我们已经在干净的架构中实现了一个 asp.net core web api 6.0 项目。 https://github.com/jasontaylordev/CleanArchitecture

所有 API 在开发模式下都可以正常工作。但在生产模式下，API 不起作用。

示例：我通过邮递员 http://localhost:5000/api/deals/public?SiteCode=wpf 发送了一个 get 请求。

我得到了 500 错误。 { "type": "https://tools.ietf.org/html/rfc7231#section-6.6.1", "title": "An error occurred while processing your request.", "status": 500 }

在终端中，输出显示如下

 Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[62]

在程序.cs

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddControllers(options =>
                options.Filters.Add<ApiExceptionFilterAttribute>())
                    .AddFluentValidation()
.AddNewtonsoftJson(options => options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore);

var app = builder.Build();

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers();
});

ApiControllerBase.cs

[ApiController]
[Route("api/[controller]")]
public abstract class ApiControllerBase : ControllerBase
{
    private ISender _mediator = null!;

    protected ISender Mediator => _mediator ??= HttpContext.RequestServices.GetRequiredService<ISender>();
}

PublicDealController.cs

[Route("api/deals/public")]
[AllowAnonymous]
public class PublicDealController : ApiControllerBase
{
    [HttpGet]
    [ProducesResponseType(StatusCodes.Status200OK)]
    [ProducesResponseType(StatusCodes.Status500InternalServerError)]
    public async Task<ActionResult<DealListBySiteCodeVm>> ListBySiteCode([FromQuery] GetDealListBySiteCodeQuery query)
    {
        var result = await Mediator.Send(query);

        return Ok(result);
    }
}

我犯了什么错误？为什么 API 不能在生产模式下工作。有人遇到过这个问题吗？请帮忙找出错误。我不知道为什么 api 不能仅在生产模式下工作。
