将凭据从reportviewer传递到报表服务器时未经授权

Question

我有以下控制器（ReportsController.cs）

using Microsoft.Reporting.WebForms;
using System;
using System.Configuration;
using System.Web.Mvc;
using System.Net;

namespace ActiveDirectoryAuthentication.Controllers
{
    public class ReportsController : Controller
    {
        // GET: Reports
        public ActionResult Index()
        {
            string ssrsUrl = ConfigurationManager.AppSettings["SSRSReportsUrl"].ToString();
            ReportViewer viewer = new ReportViewer();
            IReportServerCredentials irsc = new CustomReportCredentials("uname", "pwd", "domain");
            viewer.ServerReport.ReportServerCredentials = irsc;
            viewer.ProcessingMode = ProcessingMode.Remote;
            viewer.SizeToReportContent = true;
            viewer.AsyncRendering = true;
            viewer.ServerReport.ReportServerUrl = new Uri(ssrsUrl);
            viewer.ServerReport.ReportPath = "/Temperature_Graphs_Reports/Temperature_Graphs";
            viewer.ServerReport.Refresh();

            ViewBag.ReportViewer = viewer;

            return View();
        }
    }

    public class CustomReportCredentials : IReportServerCredentials
    {
        private string _UserName;
        private string _PassWord;
        private string _DomainName;

        public CustomReportCredentials(string UserName, string PassWord, string DomainName)
        {
            _UserName = UserName;
            _PassWord = PassWord;
            _DomainName = DomainName;
        }

        public System.Security.Principal.WindowsIdentity ImpersonationUser
        {
            get { return null; }
        }

        public ICredentials NetworkCredentials
        {
            get { return new NetworkCredential(_UserName, _PassWord, _DomainName); }
        }

        public bool GetFormsCredentials(out Cookie authCookie, out string user,
         out string password, out string authority)
        {
            authCookie = null;
            user = password = authority = null;
            return false;
        }
    }
}

和以下视图（Index.cshtml）：

@using ReportViewerForMvc;

@if (ViewBag.ReportViewer != null)
{
    @Html.ReportViewer(ViewBag.ReportViewer as Microsoft.Reporting.WebForms.ReportViewer)
}

我可以在不通过凭据的情况下查看报告（手动通过凭据）。

通过传递的凭据，我收到此错误消息：

'/'应用程序中的服务器错误。

这是rsreportserver.config的值

<AuthenticationTypes>            
  <RSWindowsNTLM/>
</AuthenticationTypes>

当我单击URL时，在Report Server Configuration Manager下的Web Portal URL中有此错误消息

The service is not available.
The report server isn’t configured properly. Contact your system administrator to resolve the issue. System administrators: The report server Web Portal URLs and Web Service URLs don’t match. Use Reporting Services Configuration Manager to configure the URLs and ensure they match.

Answer 1

据我所知，您的代码很好。我只是快速按一下boilerplate MVC project来针对我的SSRS实例进行测试，并成功运行了它，而无需更改您的代码。

所以看来问题在于您正在运行的环境：

1. [Check if you SSRS is configured接受您的特定身份验证请求（默认情况下应随NTLM进行协商，但您没有指定是否仍然适合您）。

2. ReportViewer控件本身依赖于ASP.NET会话来保持状态，因此check if you need to work around表示。

由于我对您的特定设置了解不多，所以我不能更具体了，但希望它为您提供了两个可供选择的选项。
