C# 依赖项注入不适用于具有Azure密钥保险库值asp.net core 3.0的RabitMQ服务总线

我正在使用依赖项配置服务总线，如下所示

Startup.cs

services.AddSingleton<ServiceBusTransportOptions>(sp => JsonConvert.DeserializeObject<ServiceBusTransportOptions>(Configuration.GetSection("ServiceBus").Value));

public class ServiceBusTransportOptions : IOptions<ServiceBusTransportOptions>
    {
        public TransportType Transport { get; set; } = TransportType.AzureServiceBus;

        public AzureServiceBusTransportOptions AzureServiceBus { get; set; }

        public RabbitMqTransportOptions RabbitMq { get; set; }

        public ServiceBusTransportOptions Value => this;
    }

  public static void AddServiceBus(this ContainerBuilder builder,
            string applicationName,
            Action<IContainerBuilderConfigurator> configureMassTransitBuilder,
            Action<IComponentContext, IBusFactoryConfigurator> configureServiceBus)
        {
            builder.Register(
                    _ =>
                    {
                        var config = _.Resolve<IOptions<ServiceBusTransportOptions>>().Value;
                        switch (config.Transport)
                        {
                            case TransportType.AzureServiceBus:
                                return new AzureServiceBusConfigurationProvider(config.AzureServiceBus.Value) as
                                    IServiceBusConfigurationProvider;
                            case TransportType.RabbitMq:
                                return new RabbitMqServiceBusConfigurationProvider(config.RabbitMq.Value);
                            default:
                                return new InMemoryServiceBusConfigurationProvider() as
                                    IServiceBusConfigurationProvider;
                        }

                    })
                .As<IServiceBusConfigurationProvider>()
                .SingleInstance();
        }

var config=..Resolve（）.value的值默认不与vault值映射。因此导致空指针experception

无需手动反序列化。从配置绑定到对象模型，并显式注册所需的类型

var configuration = new ConfigurationBuilder()
    .AddJsonFile("secret.json")
    .Build();
//"ConfigurationBinder.Gett<T>" method comes from
// Microsoft.Extensions.Configuration.Binder.dll
ServiceBusTransportOptions options = configuration.GetSection("ServiceBus").Get<ServiceBusTransportOptions>();
services.AddSingleton(options);

var configuration=new ConfigurationBuilder（）
.AddJsonFile（“secret.json”）
.Build（）；
//“ConfigurationBinder.Gett”方法来自
//Microsoft.Extensions.Configuration.Binder.dll
ServiceBustTransportOptions=configuration.GetSection（“ServiceBus”）.Get（）；
服务。AddSingleton（选项）；

并根据需要解决问题

//...
builder.Register(_ => {
    var config = _.Resolve<ServiceBusTransportOptions>();
    switch (config.Transport) {
        case TransportType.AzureServiceBus:
            return new AzureServiceBusConfigurationProvider(config.AzureServiceBus.Value) as
                IServiceBusConfigurationProvider;
        case TransportType.RabbitMq:
            return new RabbitMqServiceBusConfigurationProvider(config.RabbitMq.Value);
        default:
            return new InMemoryServiceBusConfigurationProvider() as
                IServiceBusConfigurationProvider;
    }
})

由于该值不在appsetting.json上，因此它们位于本地的vault文件中，它来自secret.json。这些值类似于{“ServiceBus”：“{\“Transport\”：\“RabbitMq\”，\“RabbitMq\”：{“Url\”：\”rabbitmq://localhost\“，”用户名\“：\”客人\“，”密码\“：\”客人\“}}”所以我需要得到应得的回报it@SanJaisy您可以将其加载到IConfiguration中。请告诉我。我对这项为我服务的工作感到困惑。AddSingleton（JsonConvert.DeserializeObject（Configuration.GetSection（“ServiceBus”）.Value））；使用代码生成器
