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。

我的目标是在启用 wsHttpBinding + 基本身份验证 + TransactionFlow 的情况下使用我的 AX wcf 服务。

每次我尝试在 VS 中为此服务添加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
  • 选中网站上的“要求 SSL”选项

斧头：

  • HTTP 入站端口
  • 使用“配置 AOS”而不是“配置”选项
  • 将 wsHttpBinding 与传输安全性和 TransportClientCredentialType = Basic 一起使用

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"
    logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" />
   <endToEndTracing propagateActivity="true" activityTracing="true"

  <bindings>

     </security>
    </binding>
   </wsHttpBinding>
  </bindings>

     <useRequestHeadersForMetadataAddress />
    </behavior>
   </serviceBehaviors>
  </behaviors>
        <services>
   <service behaviorConfiguration="DefaultServiceGroupBehavior"
    name="Microsoft.Dynamics.Ax.Services.WCFService">
    <endpoint address="https://ax2012r2a/MicrosoftDynamicsAXAif60/WCFService/xppservice.svc"
     binding="wsHttpBinding" bindingConfiguration="wsHttpBindingTransportBasic"
     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>

会发生什么？

任何帮助将不胜感激。谢谢你。
