SSRS 报告查看器显示响应“请求失败，响应为空”

编程问答 2022-06-01

问题描述

我的目标是显示来自远程 ssrs 报告服务器的报告。我正在尝试显示有关 ASP.NET MVC 框架的示例报告。 注意，我可以通过用户身份验证在浏览器上查看报告。

在 runReport.aspx 上，我有以下内容。

    
 <%@ Register Assembly="Microsoft.ReportViewer.WebForms,Version=15.0.0.0,Culture=neutral,PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
 <!DOCTYPE html>
    
 <html xmlns="http://www.w3.org/1999/xhtml">
 <head runat="server">
     <title></title>
 </head>
 <body>
     <form runat="server">
         <asp:ScriptManager runat="server"></asp:ScriptManager>
         <rsweb:ReportViewer ID="MainReportViewer" runat="server" BackColor="White"
             Font-Names="Verdana" Font-Size="8pt" InteractiveDeviceInfos=" (Collection)"
             ProcessingMode="Remote" ShowBackButton="False" ShowFindControls="False"
             ShowPageNavigationControls="False" SizetoReportContent="True"
             ToolBarItemBorderColor="White" ToolBarItemHoverBackColor="White"
             WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" Width="100%">
             <ServerReport reportserverUrl="" />
         </rsweb:ReportViewer>
     </form>
 </body>
 </html>

关于背后的代码

protected void Page_Load(object sender,EventArgs e)        {            
         MainReportViewer.ProcessingMode = ProcessingMode.Remote; 
         IreportserverCredentials irsc = new CustomreportCredentials("username","password","https://servername.com"); 
         MainReportViewer.ServerReport.reportserverCredentials = irsc;  
         MainReportViewer.ServerReport.reportserverUrl = new Uri("https://servername.com/reports");  
         MainReportViewer.ServerReport.ReportPath = "/report/Sample_Report_Project" + "/" + "Report_1";       
 }

在 CustomreportCredentials.cs 上

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;
         }
     }
