在没有Report Viewer的情况下将SSRS报告嵌入网页

Question

I have an existing web application written in VS2008 & C# where I need to embed an SSRS report into a web page. The database/SSRS server is offsite and behind a firewall and only accessible via IP from the separate web server box. The database box is running SQL Server 2008R2. I cannot use the Report Viewer control as a solution.

I have tried both the SSRS web service and URL access. Using the web service throws errors when calling LoadReport and/or Render methods. Using URL access generates an error for the path of the report item. I have tried many different code samples and methods to resolve this with no luck. Does anyone have a working code sample that I can use to get this to work?

Ideally I'd like some way to have HTML returned from a call that I can then place into a DIV tag or iframe.

Answer 1

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 ie, 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"]
    );
}

尝试在iframe中调用报表的相同URI。
