我的问题....

我正在尝试从 Silverlight 和 WCF basicHttpBinding 访问会话...

我看到了一些可能的帖子（http://www.dotnetspider.com/Silverlight-Tutorial-317.aspx）

我的场景是：

Silverright 4 FW 3.5

在 web.config 我有

<system.serviceModel>
    <behaviors>
        <serviceBehaviors>
            <behavior name="ViewModelDemo.Web.Service1Behavior">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="false" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <services>
        <service behaviorConfiguration="ViewModelDemo.Web.Service1Behavior" name="ViewModelDemo.Web.Service1">
            <endpoint address="" binding="basicHttpBinding" contract="ViewModelDemo.Web.Service1">
                <identity>
                    <dns value="localhost" />
                </identity>
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        </service>
    </services>
</system.serviceModel>

和我的服务：

[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class Service1
{
    [OperationContract]
    publicvoid Test()
    {
        var session = System.Web.HttpContext.Current.Session;
    }
}

这是电话

                var client = new Service1Client();
                client.GetUserMacroFunctionsCompleted += new System.EventHandler<GetUserMacroFunctionsCompletedEventArgs>(client_GetUserMacroFunctionsCompleted);
                client.GetUserMacroFunctionsAsync();


void client_GetUserMacroFunctionsCompleted(object sender, GetUserMacroFunctionsCompletedEventArgs e)
    {
        var test =  ((Collection<Function>)e.Result);
    }

HttpContext.Current 始终为空！

有什么建议么？

是的 HttpContext 必须始终为空，因为您的服务配置不设置 ASP.NET 兼容性，并且您的服务不需要 ASP.NET 兼容性。

将此添加到您的配置中：

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

并进行更改AspNetCompatibilityRequirements，以使您的服务在没有先前配置的情况下无法托管：

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

aspNetCompatibilityEnabled="true"allowCookies="true"在我设置客户端绑定配置之前对我没有帮助。

更新您的 web.config 文件以包含

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />    
</system.serviceModel>

这应该可以工作，或者也将合同上的 AspNetCompatibilityRequirementsMode 属性更改为必需。
