报告服务:获取生成的报告的PDF

Question

我有一个报告服务服务器已经有一些运行报告,我现在需要通过自定义网站(运行asp.net MVC3)生成它们.

我需要以流/字节的形式检索此报告以将其发送给用户.没有"报告查看器"左右.

上次我使用报告服务是使用sql 2005,我们应该作为参考一个不起眼的asmx文件.

现在是什么,sql server报告2008 R2,.Net4和visual studio 2010？我找不到解释整个事情的教程.

(实际上我找不到sql 2008 r2没有报表查看器的教程)

Answer 1

MSDN提供了几种方法.我经常在ASP .NET应用程序中使用URL访问快速简单的PDF按钮.

这是一个快速破解的代码.可以将其清理为使用集成身份验证,并且可以通过多种方式存储报告名称.(我从一些旧的代码中剪切并粘贴了这个代码,它会将报告存储到数据库中,然后可以从数据库返回该代码.

// First read in the report into memory.

string strReportUser = "RSUserName";
string strReportUserPW = "MySecretPassword";
string strReportUserDomain = "DomainName";

string sTargetURL = "http://SqlServer/ReportServer?" +
   "/MyReportFolder/Report1&rs:Command=Render&rs:format=PDF&ReportParam=" +
   ParamValue;

HttpWebRequest req =
      (HttpWebRequest)WebRequest.Create( sTargetURL );
req.PreAuthenticate = true;
req.Credentials = new System.Net.NetworkCredential(
    strReportUser,
    strReportUserPW,
    strReportUserDomain );

HttpWebResponse HttpWResp = (HttpWebResponse)req.GetResponse();

Stream fStream = HttpWResp.GetResponseStream();




//Now turn around and send this as the response..
byte[] fileBytes = ReadFully( fStream );
// Could save to a database or file here as well.

Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader(
    "content-disposition",
    "attachment; filename=\"Report For " +
        ParamValue + ".pdf\"" );
Response.BinaryWrite( fileBytes );
Response.Flush();
HttpWResp.Close();
Response.End();

ReadFully是

public static byte[] ReadFully( Stream input )
{
   using ( MemoryStream ms = new MemoryStream() )
   {
      input.CopyTo( ms );
      return ms.ToArray();
   }
}
