将凭据传递给Sql Report Server 2008
我在C＃中很新，我的英语不太好 – 如果我错过了一点，请提前抱歉。
我尝试使用ReportService控件构建一个ASP.NET网站。 您可能已经知道，SSRS 2008不允许匿名登录。 因此，我尝试将Credentials传递给SSRS，SSRS将存储在我的网页中，以便用户无需登录即可查看报告。
我找到了下面的代码并将其放在我的WebForm ，但我遇到了报告参数的问题。
-
如果报告参数有默认值，则以下代码可以正常工作。
-
但是，如果我尝试更改参数的值，整个页面就是
刷新之前，我点击“查看报告”按钮，全部
参数重置为默认值或空值。
有关如何避免刷新整个页面的任何建议，或者将登录信息传递给SSRS的其他方法？ 非常感谢提前。
using System; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using System.Net; using Microsoft.Reporting.WebForms; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { ReportViewer1.Width = 800; ReportViewer1.Height = 600; ReportViewer1.ProcessingMode = ProcessingMode.Remote; IReportServerCredentials irsc =new CustomReportCredentials("administrator", "MYpassworw", "domena"); ReportViewer1.ServerReport.ReportServerCredentials = irsc; ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://192.168.0.1/ReportServer/"); ReportViewer1.ServerReport.ReportPath = "/autonarudzba/listanarudzbi"; ReportViewer1.ServerReport.Refresh(); } } public class CustomReportCredentials : IReportServerCredentials { private string _UserName; private string _PassWord; private string _DomainName; public CustomReportCredentials(string UserName, string PassWord, string DomainName) { _UserName = UserName; _PassWord = PassWord; _DomainName = DomainName; } public System.Security.Principal.WindowsIdentity ImpersonationUser { get { return null; } } public ICredentials NetworkCredentials { get { return new NetworkCredential(_UserName, _PassWord, _DomainName); } } public bool GetFormsCredentials(out Cookie authCookie, out string user, out string password, out string authority) { authCookie = null; user = password = authority = null; return false; } }
我真的没有搞乱SSRS – 但是我的ASP.NET帽子告诉我你可能想把这些东西包装在if (!IsPostBack)块中以防止它在页面刷新上运行。 我的猜测是ReportViewer1.ServerReport.Refresh()再次拉出默认值。
protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { ReportViewer1.Width = 800; ReportViewer1.Height = 600; ReportViewer1.ProcessingMode = ProcessingMode.Remote; IReportServerCredentials irsc =new CustomReportCredentials("administrator", "MYpassworw", "domena"); ReportViewer1.ServerReport.ReportServerCredentials = irsc; ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://192.168.0.1/ReportServer/"); ReportViewer1.ServerReport.ReportPath = "/autonarudzba/listanarudzbi"; ReportViewer1.ServerReport.Refresh(); } }
我创建了新function，并在属性，事件，reportViewer的设计视图中将其选中。 （在选择INIT i）
之后，页面正常工作，我可以更改参数的值。
Default.aspx现在看起来像：
Default.aspx.cs看起来像这样
public void Admir(object sender, EventArgs e) { ReportViewer1.Width = 800; ReportViewer1.Height = 600; ReportViewer1.ProcessingMode = ProcessingMode.Remote; IReportServerCredentials irsc = new CustomReportCredentials("administrator", "mypass", "domena"); ReportViewer1.ServerReport.ReportServerCredentials = irsc; ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://192.168.0.1/ReportServer/"); ReportViewer1.ServerReport.ReportPath = "/autonarudzba/listanarudzbi"; ReportViewer1.ServerReport.Refresh(); } protected void Page_Load(object sender, EventArgs e) { }
您可以在页面加载事件中使用以下代码来提供参数
ReportParameter[] reportParameterCollection = new ReportParameter[1]; //Array size describes the number of paramaters. reportParameterCollection[0] = new ReportParameter(); reportParameterCollection[0].Name = "ACCMGR"; //Give Your Parameter Name reportParameterCollection[0].Values.Add("12"); //Pass Parametrs's value here. ReportViewer1.ServerReport.SetParameters(reportParameterCollection); ReportViewer1.ServerReport.Refresh();
我希望这对你有用
我找到了解决方案。 您必须先设置凭据，然后必须为reportviewer设置参数。
rvCommon.ProcessingMode = ProcessingMode.Remote; rvCommon.ServerReport.ReportServerUrl = new System.Uri("SSRSReportServerURL"); rvCommon.ServerReport.ReportPath = "/Report Parts/CustomerMainReport2" ; Microsoft.Reporting.WebForms.ReportParameter[] RptParameters = new Microsoft.Reporting.WebForms.ReportParameter[1]; rvCommon.ServerReport.ReportServerCredentials = new ReportCredentials("username", "password", ""); RptParameters[0] = new Microsoft.Reporting.WebForms.ReportParameter("CustomerId", "1"); rvCommon.ServerReport.SetParameters(RptParameters); rvCommon.ServerReport.Refresh();
