报告查看器错误消息"客户端找到响应内容类型''但预期'文本xml'请求失败并显示空响应."

Question

我收到了错误

client found response content type of '' but expected 'text xml' The request failed with an empty response.

当我尝试执行以下代码时.

//create a PDF from the SQL report
ReportViewer rview = new ReportViewer();

rview.ServerReport.ReportServerUrl = new Uri("http://server/ReportServer$MSSQL2K5?");

List<ReportParameter> paramList = new List<ReportParameter>();
paramList.Add(new Microsoft.Reporting.WinForms.ReportParameter("Batch", "1"));
paramList.Add(new Microsoft.Reporting.WinForms.ReportParameter("InvoiceNo", "0"));
rview.ServerReport.ReportPath = "Report/Report Invoice";

rview.ServerReport.SetParameters(paramList);

string mimeType, encoding, extension, deviceInfo;
string[] streamids;
Microsoft.Reporting.WinForms.Warning[] warnings;
string format = "PDF"; //Desired format goes here (PDF, Excel, or Image)             

deviceInfo =
"<DeviceInfo>" +
"<SimplePageHeaders>True</SimplePageHeaders>" +
"</DeviceInfo>";

byte[] bytes = rview.LocalReport.Render(format, deviceInfo, out mimeType, out encoding, out extension, out streamids, out warnings);

该行发生错误:

rview.ServerReport.SetParameters(paramList);

地址是正确的,因为我可以通过网络浏览器加载报告:

this.webBrowser1.Navigate("http://server/ReportServer$MSSQL2K5?/Report/Report Invoice&Batch=1&InvoiceNo=0");

我需要使用报表查看器加载报表,以便我可以导出为PDF.

Answer 1

在我的情况下,此错误是由SSRS服务器耗尽硬盘空间引起的.

Answer 2

尝试将Uri设置为完整服务uri,例如:

new Uri("http://server/ReportServer$MSSQL2K5/reportservice2005.asmx?")

另外,你需要尾随?吗？我不确定,但如果需要的话,不会附加SetParameters吗？
