c# - 在没有报表查看器的情况下将 SSRS 报表嵌入网页

Question

我有一个用 VS2008 和 C# 编写的现有 Web 应用程序，我需要在其中将 SSRS 报告嵌入到网页中。数据库/SSRS 服务器位于异地并在防火墙后面，只能通过单独的 Web 服务器框的 IP 访问。数据库框正在运行 SQL Server 2008R2。 我无法使用 Report Viewer 控件作为解决方案。

我已经尝试了 SSRS 网络服务和 URL 访问。使用 Web 服务在调用 LoadReport 和/或 Render 方法时会引发错误。使用 URL 访问会生成报告项路径的错误。我尝试了许多不同的代码示例和方法来解决这个问题，但没有成功。有没有人有我可以用来让它工作的工作代码示例？

理想情况下，我希望通过某种方式从调用中返回 HTML，然后我可以将其放入 DIV 标记或 iframe 中。

Here is a sample it is working for me

Web config ...

<!-- Reporting -->
        <add key="ReportingUserName" value="xxxxx\xxxx" />
        <add key="ReportingPassword" value="xxxxxxxxx" />
        <add key="ReportingDomain" value="xxxxxxx" />


     <endpoint address="http://xxxxxx/ReportServer/ReportExecution2005.asmx" binding="basicHttpBinding" bindingConfiguration="basicHttpBindingConfig" contract="SSRS.ReportExecutionServiceSoap" name="ReportExecutionServiceSoap" />

     <!-- Binding for Reporting Services over HTTP -->
            <binding name="basicHttpBindingConfig" allowCookies="true" maxReceivedMessageSize="52428800" sendTimeout="00:10:00">
              <security mode="TransportCredentialOnly">
                <transport clientCredentialType="Ntlm" proxyCredentialType="None" realm="" />
                <message clientCredentialType="UserName" algorithmSuite="Default" />
              </security>
            </binding>

outputType ReportFormat i.e, Pdf,Image,Excel,Ffd

deviceInfo contains the XML string for reporting services based on the ReportFormat

reportPath contains report path on SSRS server "/xxx/datarecord-Table"

  private SsrsResponse ExecuteSsrsReport(string reportPath, IEnumerable<KeyValuePair<string, string>> parameters,
        string outputType, string deviceInfo)
    {
        using (var rs = new ReportExecutionServiceSoapClient())
        {
            if (rs.ClientCredentials != null)
            {
                rs.ClientCredentials.Windows.ClientCredential = GetReportingCredentials();
                rs.ClientCredentials.Windows.AllowedImpersonationLevel =
                    System.Security.Principal.TokenImpersonationLevel.Impersonation;
            }

            byte[] result;
            Warning[] warnings;
            string[] streamIds;

            ParameterValue[] parameterValues =
                parameters.Select(p => new ParameterValue { Name = p.Key, Value = p.Value }).ToArray();

            ExecutionInfo execInfo;
            ServerInfoHeader serverInfoHeader;

            ExecutionHeader execHeader =
                rs.LoadReport(null, reportPath, null, out serverInfoHeader, out execInfo);
            rs.SetExecutionParameters(execHeader, null, parameterValues, "en-us", out execInfo);

            string extension, mimeType, encoding;
            rs.Render(execHeader, null, outputType, deviceInfo,
                out result, out extension, out mimeType, out encoding, out warnings, out streamIds);

            return new SsrsResponse(result, extension, mimeType, encoding);
        }
    }

private NetworkCredential GetReportingCredentials()
{
    return new NetworkCredential(
        ConfigurationManager.AppSettings["ReportingUserName"],
        ConfigurationManager.AppSettings["ReportingPassword"],
        ConfigurationManager.AppSettings["ReportingDomain"]
    );
}
