我已经为以下 .NET 框架 4.0 异常花费了一天的工作时间。我在网上研究了解决方案,但我还没有找到一个可行的解决方案。请提前帮助和感谢。

我的 asp.net Web 应用程序在具有 IIS 8.0 和本地 SQL Server 2012 实例的本地 PC 环境中运行良好,但是当我将其部署到同时具有 IIS 8.0 和 SQL Server 2012 实例的 Web 服务器时出现异常。

例外:

详情/我的故事:

我有一个 asp.net Web 表单应用程序,它有一个 Web 引用并使用 SQL Server 2012 报告服务的 SOAP Web 服务(请参阅http://msdn.microsoft.com/en-us/library/ee640743.aspx)。我的名为“MyAspNetSolution”的asp.net Web 表单解决方案是使用VS 2012 / .NET framework 4.5 和本地企业版SQL Server 2012 开发的。该解决方案包含Web 表单应用程序项目和其他自定义类库项目。其中一个类库项目是一个名为“MyAspNetSolution.Services”的类库项目,它具有对 SSRS SOAP Web 服务的 Web 引用和使用,例如:

...
using MyAspNetSolution.Services.ReportService2010;
using System.Net;
...

namespace MyAspNetSolution.Services
{
    public class ReportServerInfoService
    {
            public CatalogItem[] ListReportCollection(string itemPath, bool recursive)
            {
            CatalogItem[] reportCollection = {};

            try
            {
                ReportService2010.ReportingService2010SoapClient client = new ReportService2010.ReportingService2010SoapClient();
                client.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
                client.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

                client.Open();
                TrustedUserHeader t = new TrustedUserHeader();

                try
                {
                    // I need to list of children of a specified folder.
                    client.ListChildren(t, itemPath, recursive, out reportCollection); // see http://msdn.microsoft.com/en-us/library/reportservice2010.reportingservice2010.listchildren.aspx
                }
                catch (SoapException ex)
                {
                    _logger.Error("ReportServerManagementService--" + ex);
                }
            }
            catch (SoapException ex)
            {
                _logger.Error("ReportServerManagementService--" + ex);
            }

            return reportCollection;
           }
    }
}

我的 Web 应用程序项目Web.config中 SQL Server 2012 报告服务的 SOAP Web 服务的端点、绑定和其他部分如下所示:

...
 <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="ReportingService2010Soap">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Ntlm"></transport>
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://my-pc-network-domain-or-server-domain/ReportServer_SQL2012/ReportService2010.asmx" binding="basicHttpBinding" bindingConfiguration="ReportingService2010Soap" contract="ReportService2010.ReportingService2010Soap" name="ReportingService2010Soap"/>
    </client>
  </system.serviceModel>
...  

附言:

我还查看了以下线程(用于 SharePoint 客户端开发),代码与我正在开发的代码(用于 SSRS 客户端开发)相同,但在我的本地 PC 环境中工作,而不是在 Web 服务器上。

Sharepoint Web 服务——HTTP 请求未经客户端身份验证方案“Ntlm”的授权。从服务器收到的身份验证标头是“NTLM”

您应该尝试 NetworkCredentials 并将它们传递给客户端。如果您仍然收到错误,请将其放在您的 wcf 配置文件中:

<identity>
    <servicePrincipalName value=""/>
</identity>

谢谢
