Question

我在使用自定义 AX 2012 R3 CU9 AIF WCF服务时遇到了一个非常奇怪的问题。

我的目标是使用我的AX wcf服务，启用wsHttpBinding + Basic身份验证+ TransactionFlow。

每次我尝试在VS中添加此服务的服务引用时都会出现此错误\在浏览器中打开服务链接：

Object Server 01:  An error has occurred in the services framework.  Method: AifMessageInspector::AfterReceiveRequest.  Error: System.NullReferenceException: Object reference not set to an instance of an object.
   at Microsoft.Dynamics.Ax.Services.AxServiceOperationContext.InitializeSession()
   at Microsoft.Dynamics.Ax.Services.AxServiceOperationContext.InitializeContext()
   at Microsoft.Dynamics.Ax.Services.AxServiceOperationContext.Attach(OperationContext owner)
   at System.ServiceModel.ExtensionCollection`1.InsertItem(Int32 index, IExtension`1 item)
   at System.Collections.Generic.SynchronizedCollection`1.Add(T item)
   at Microsoft.Dynamics.Ax.Services.AifMessageInspector.AfterReceiveRequest(Message& request, IClientChannel channel, InstanceContext instanceContext)

IIS：

仅启用匿名和基本身份验证
创建自签名证书并将其添加到主机上的服务器证书，“受信任的根证书颁发机构”和“企业信任”文件夹
使用此证书在此网站上启用https绑定
在网站

AX：

HTTP入站端口
使用“配置AOS”代替“配置”选项
将wsHttpBinding与Transport安全性和使用 TransportClientCredentialType = Basic

AX生成的Web配置（aos.config）：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.diagnostics />
 <system.serviceModel>
        <diagnostics>
   <messageLogging logEntireMessage="true" logKnownPii="true" logMalformedMessages="true"

     name="DefaultServiceGroupEndPoint" contract="Microsoft.Dynamics.Ax.Services.ServiceGroup" />
   </service>
  </services>
        <client>
   <endpoint address="https://ax2012r2a/MicrosoftDynamicsAXAif60/WCFService/xppservice.svc"
    binding="wsHttpBinding" bindingConfiguration="wsHttpBindingTransportBasic"
    contract="*" name="DefaultServiceGroupEndPoint" />
  </client>
    </system.serviceModel>
</configuration>

可能会发生什么？

任何帮助都将受到高度赞赏。谢谢。
