Azure函数未注册任何身份验证处理程序

Question

我正在尝试创建一个简单的V2 Azure函数。它可以是匿名身份验证级别，因为它将由API管理保护。

构造函数和函数如下所示：

public ProvideOfsPortfolioData(IMediator mediatorService, IInstrumentationService instrumentationService, ILogger<ProvideOfsPortfolioData> logger)
{
_mediatorService = mediatorService;
_instrumentationService = instrumentationService;
_logger = logger;
_typeName = "Interfaces.Ce.Presentation.AzureFunctions.ProvideOfsPortfolioData";
}
[FunctionName("ProvideOfsPortfolioData")]
public async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = null)] HttpRequest req)
{
_logger.LogInformation($"{_typeName}.Run] - Started");
}

当我试图在VS2019中点击F5进行调试时，我在控制台窗口中收到以下错误：

An unhandled host error has occurred.
Microsoft.AspNetCore.Authentication.Core: No authentication handlers
are registered. Did you forget to call
AddAuthentication().Add[SomeAuthHandler]("WebJobsAuthLevel",...)?.

我应该如何添加所需的处理程序？

看起来有些代码试图利用AspNetCore.Authentication.Core模块进行身份验证。使用身份验证时，由用户选择身份验证提供程序。在这种情况下，在startup.cs文件中不会调用AddAuthentication((命令。有关此方面的更多文档，请访问：https://learn.microsoft.com/en-us/aspnet/core/migration/1x-to-2x/identity-2x?view=aspnetcore-3.0#认证中间件和服务

在这个特定的例子中，以下代码被识别为调用身份验证模块：

builder.Services.AddMvc().AddFluentValidation(fv =>
fv.RegisterValidatorsFromAssemblyContaining<
Application.Portfolio.Commands.AssignSinglePortfolio.Validator>());
builder.Services.AddTransient(typeof(IPipelineBehavior<,>), typeof(RequestValidationBehaviour<,>));

由于目标是匿名身份验证，因此已对此进行了注释以解决问题。
