Question

我用MVC 5和WCF创建了一个项目。我有一个 AspNetCompatibilityRequirementsMode.Allowed 以及W.Web服务

<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />

在MVC Controller中，我正在为会话添加价值

public class HomeController : Controller
    {
        ServiceReference1.MyService2Client ur = new ServiceReference1.MyService2Client();
        public ActionResult Index()
        {
            HttpContext.Session.Add("UserId", 1);
            ViewBag.msg = ur.Test();

            return View();
        }
}

在WCF服务中：

[AspNetCompatibilityRequirements(RequirementsMode
       = AspNetCompatibilityRequirementsMode.Allowed)]
    public class MyService2 : IMyService2
    {
        private Test _test;
        public MyService2(Test test)
        {
            _test = test;
        }

        public string Test()
        {
            var test = HttpContext.Current.Session["UserId"]; // Its Coming as NULL
            return "Serivce Success";
        }
    }

即使我在MVC Controller中添加会话变量并尝试访问WCF服务中的会话变量，当请求到WCF服务时，会话变量也不存在。

在MVC web.config中：

 <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IMyService2" />
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:30380/MyService2.svc" binding="basicHttpBinding"
        bindingConfiguration="BasicHttpBinding_IMyService2" contract="ServiceReference1.IMyService2"
        name="BasicHttpBinding_IMyService2" />
    </client>
  </system.serviceModel>

在WCF web.config中：

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https"  />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
  </system.serviceModel>

帮我解决它

wcf Web服务中没有httpcontext，
https://docs.microsoft.com/en-us/dotnet/framework/wcf/feature-details/wcf-services-and-aspnet
如文档所述，我们使用OperationContext。
https://docs.microsoft.com/en-us/dotnet/api/system.servicemodel.operationcontext?redirectedfrom=MSDN&view=netframework-4.7.2
如果要存储用户数据，则应启用WCF会话模式。在这种情况下，WCF服务器可以识别客户端。它可以与从特定客户端发送到特定服务实例的所有消息关联。

在WCF服务和MVC 5之间共享HttpContext
