服務器上的加載報告失敗-Crystal Reports

Question

我有一個水晶報表查看器頁面，可以在我的桌面開發計算機上很好地顯示報表。 我用於此查看器頁面的代碼是：

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using LoyalitySystem;
using System.Configuration;
using HQ.DatabaseGateway;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
using System.IO;

public partial class WebPages_DynamicReports_CrystalReportViewerPage : BasePage
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string reportPath = Server.MapPath((string)Utils.GetSessionNavigator(this).GetDataFromCurrentPage(PageParams.Reports.Report));
        ReportDocument rep = new ReportDocument();

        try
        {
            if (!File.Exists(reportPath))
            {
                Response.Write("The specified report does not exist \n");
            }

            rep.Load(reportPath);
            LoadReport(rep);
            this.CrystalReportViewer1.ToolPanelView = CrystalDecisions.Web.ToolPanelViewType.None;
            this.CrystalReportViewer1.HasToggleGroupTreeButton = false;
            this.CrystalReportViewer1.ReportSource = rep;
        }
        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }
    }

    private bool LoadReport(ReportDocument doc)
    {
        TableLogOnInfo crTableLogonInfo;
        Sections crSections;
        Database crDatabase;
        Tables crTables;
        ReportDocument crSubreportDocument;
        ReportObjects crReportObjects;
        SubreportObject crSubreportObject;

        try
        {
            ConnectionInfo con = new ConnectionInfo();
            con.ServerName = ConfigurationManager.AppSettings["dbsource"];
            con.DatabaseName = Utils.GetSessionNavigator(this).UserData.DatabaseName;
            con.UserID = ConfigurationManager.AppSettings["uid"];
            con.Password = ConfigurationManager.AppSettings["pwd"];
            crDatabase = doc.Database;
            crTables = crDatabase.Tables;

            //loop through all the tables and pass in the connection info
            foreach (CrystalDecisions.CrystalReports.Engine.Table crTable in crTables)
            {
                crTableLogonInfo = crTable.LogOnInfo;
                crTableLogonInfo.ConnectionInfo = con;
                crTable.ApplyLogOnInfo(crTableLogonInfo);
            }

            // set the crSections object to the current report's sections
            crSections = doc.ReportDefinition.Sections;

            // loop through all the sections to find all the report objects
            foreach (Section crSection in crSections)
            {
                crReportObjects = crSection.ReportObjects;
                // loop through all the report objects to find all the subreports
                foreach (ReportObject crReportObject in crReportObjects)
                {
                    if (crReportObject.Kind == ReportObjectKind.SubreportObject)
                    {
                        crSubreportObject = (SubreportObject)crReportObject;

                        // open the subreport object
                        crSubreportDocument = crSubreportObject.OpenSubreport(crSubreportObject.SubreportName);

                        // set the database and tables objects to work with the subreport
                        crDatabase = crSubreportDocument.Database;
                        crTables = crDatabase.Tables;

                        // loop through all the tables in the subreport and 
                        // set up the connection info and apply it to the tables
                        foreach (CrystalDecisions.CrystalReports.Engine.Table crTable in crTables)
                        {
                            crTableLogonInfo = crTable.LogOnInfo;
                            crTableLogonInfo.ConnectionInfo = con;
                            crTable.ApplyLogOnInfo(crTableLogonInfo);
                        }
                    }
                }
            }
        }
        catch (Exception e)
        {
            Response.Write(e.Message);
            return false;
        }

        return true;
    }
}

如前所述，這在本地托管我的應用程序時可以很好地工作，但是在生產服務器上，我運行的每個報告都出現“加載報告失敗”，並且通過檢查文件是否存在，可以看到請求的文件是被發現。

我的.aspx標記是：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="CrystalReportViewerPage.aspx.cs"
    Inherits="WebPages_DynamicReports_CrystalReportViewerPage" %>

<%@ Register Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"

我的web.config文件包含：

    <sectionGroup name="businessObjects">
        <sectionGroup name="crystalReports">
            <section name="rptBuildProvider" type="CrystalDecisions.Shared.RptBuildProviderHandler, CrystalDecisions.Shared, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304, Custom=null"/>
        </sectionGroup>
    </sectionGroup>

        </buildProviders>

而且我已在不同時間在Windows 2008 R2數據中心服務器上同時安裝了CRforVS_redist_install_64bit_13_0_2和CRforVS_redist_install_32bit_13_0_2再CRforVS_redist_install_64bit_13_0_2 ，並且都無法解決該問題。 該應用程序連接到位於Amazon EC2實例本身上的Amazon RDS SQL Server實例。

我已經在互聯網上搜索了一段時間，以找到解決該問題的方法，但是顯然“ Load Report Failed”消息的含義很廣泛，因此我希望我可以在此問題的特殊情況下提供幫助來解決此問題。

我已經在這個問題上停留了一個多星期，因此，如果能提供任何幫助，我將不勝感激。

此消息通常表明使用提供的路徑無法使用該報告。 如果未安裝運行時，您將收到不同的消息。在您的情況下，所有內容均已正確安裝，但該報告在reportPath + rpName中不可用。 您可以調試並檢查reportPath + rpName是否指向，以及報告是否確實存在。 嘗試使用Path.Combine（reportPath，rpName）-如有必要，它將添加\\。 還檢查IIS是否有權訪問reportPath文件夾中的報告。
