在字典中找不到密钥

Question

以下异常，似乎提示找不到配置值之一：

        }
    }
}

流程：

1. 针对微服务发布正文
2. 微服务启动编排，其中之一是使用共享接口IOCLineItemsActor 上的方法

根据以下，异常发生在第75行，见innerexception：

...\Sales.o777.OrderManagement\\Controller\\OrderCaptureController.cs:line 75\r\n--- End of stack trace from pr...

第 74/75 行如下：

var proxy = ActorProxy.Create<IOCLineItemsActor>(ActorId.CreateRandom(), new Uri(@"fabric:/abc.API/OCLineItemsActor/OCLineItemsActorService"));

await proxy.MergeLineItemsToOpportunity(orderCapture.Id, (Guid)orderCapture.OpportunityId); //this is line 75 ! seems like it may be looking for a onfig setting here?

发布开发环境时，我们没有得到给定的键不在字典中异常；但是，当我发布到 QA 时，我们确实得到了这个异常。

我比较了 ApplicationParameters 文件（dev vs qa），它们是相同的。

我做错了什么？我如何确定它缺少哪个键？

这里是MergeLineItemsToOpportunity

    internal class OCLineItemsActor : Actor, IOCLineItemsActor
    {
        /// <summary>
        ///     Initializes a new instance of OCLineItemsActor
        /// </summary>
        /// <param name="actorService">
        ///     The Microsoft.ServiceFabric.Actors.Runtime.ActorService that will host this ocLineItemsActor
        ///     instance.
        /// </param>
        /// <param name="actorId">The Microsoft.ServiceFabric.Actors.ActorId for this ocLineItemsActor instance.</param>
        public OCLineItemsActor(ActorService actorService, ActorId actorId)
            : base(actorService, actorId)
        {
            CMConnectionString = FabricRuntime.GetActivationContext().GetConfigurationPackageObject("Config")
                .Settings.Sections["CRMWebService"].Parameters["CMDatabaseConnection"].Value;
            CRMConnectionString = FabricRuntime.GetActivationContext().GetConfigurationPackageObject("Config")
                .Settings.Sections["CRMWebService"].Parameters["CRMDatabaseConnection"].Value;
            SprocExecutor = new SprocExecutor(CMConnectionString, CRMConnectionString);
        }

    public Task MergeLineItemsToOpportunity(int orderCaptureId, Guid opportunityId)
    {
        OCLineItemsEventSource.Current.Message("orderCaptureId: " + orderCaptureId);

        var executor = new SprocExecutor(CMConnectionString, CRMConnectionString);

        SprocExecutor.MergeLineItemsToOpportunity(orderCaptureId, opportunityId);

        return Task.CompletedTask;
    }

}

Answer 1

我没有直接引用Interfaces DLL，而是引用了包含接口的csproj 文件。为什么这有效，我不知道。
