如何在超文本传输协议触发器azure函数app中添加自定义启动类

Question

Azure http 触发器函数应用不随启动一起提供。我想实现azure AD身份验证，它添加了Microsoft.AspNetCore.Builder的UseAuthentication方法来验证令牌并对用户进行身份验证。

目前Http触发器正在点击Run方法directly.There应该是一些中间件逻辑来添加服务和配置

创业班

public void ConfigureServices(IServiceCollection services)
{            services.AddAuthentication(AzureADDefaults.BearerAuthenticationScheme)
               .AddAzureADBearer(options => Configuration.Bind("ConfigName", options));
}


public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory logger)
{
   app.UseAuthentication();
}

授权属性下面的后实现应该验证令牌并允许/拒绝用户访问。

public static class Function1
   {
       [Authorize]
       [FunctionName("Function1")]
       public static async Task<IActionResult> Run(
           [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
           ILogger log)
       {
           log.LogInformation("C# HTTP trigger function processed a request.");

           return (ActionResult)new OkObjectResult($"Hello");
       }
   }

请帮忙。

你可以 [assembly： WebJobsStartup（typeof（MyNamespace.Startup））] 来注册和配置依赖关系注入绑定。请参阅此文章。

[assembly: WebJobsStartup(typeof(MyNamespace.MyStartup))]
namespace MyNamespace
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static async Task<IActionResult> Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");

            return (ActionResult)new OkObjectResult($"Hello");
        }
    }
    public class MyStartup : IWebJobsStartup
    {
        public void Configure(IWebJobsBuilder builder)
        {
        builder.Services...
        }
    }
}

Azure函数默认没有< code>Startup类。您可以使用< code>IWebJobStartup添加服务，但不能添加自定义中间件。
