我正在运行一个 .NET MVC 3 Web 应用程序。我正在通过网络表单将报告嵌入到我的网页中。下面是我的 webform 类，它将身份验证凭据传递给报表服务器，并在 reportviewer webform 中显示报表，但我仍然收到拒绝访问错误。有什么建议么？
public partial class Reports : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
reportViewer.ServerReport.ReportServerCredentials = new MyReportServerCredentials();
//Sets the report server based upon environment
string reportServer = ConfigurationManager.AppSettings["url-reportServer"].ToString();
//Sets the report path based upon the environment and the report name based upon which report is selected (variable passed through URL)
string reportPath = ConfigurationManager.AppSettings["url-reportPath"].ToString() + Request.QueryString["reportName"];
// Set the processing mode for the ReportViewer to Remote to read from server
reportViewer.ProcessingMode = ProcessingMode.Remote;
ServerReport serverReport = reportViewer.ServerReport;
// Set the report server URL and report path
serverReport.ReportServerUrl = new Uri(reportServer);
serverReport.ReportPath = reportPath;
}
[Serializable]
public sealed class MyReportServerCredentials : IReportServerCredentials
{
public WindowsIdentity ImpersonationUser
{
get
{
// Use the default Windows user. Credentials will be
// provided by the NetworkCredentials property.
return null;
}
}
public ICredentials NetworkCredentials
{
get
{
// Read the user information from the Web.config file.
// By reading the information on demand instead of
// storing it, the credentials will not be stored in
// session, reducing the vulnerable surface area to the
// Web.config file, which can be secured with an ACL.
// User name
string userName = ConfigurationManager.AppSettings["MyReportViewerUser"];
if (string.IsNullOrEmpty(userName))
throw new Exception("Missing user name from web.config file");
// Password
string password = ConfigurationManager.AppSettings["MyReportViewerPassword"];
if (string.IsNullOrEmpty(password))
throw new Exception("Missing password from web.config file");
// Domain
string domain = ConfigurationManager.AppSettings["MyReportViewerDomain"];
if (string.IsNullOrEmpty(domain))
throw new Exception("Missing domain from web.config file");
return new NetworkCredential(userName, password, domain);
}
}
public bool GetFormsCredentials(out Cookie authCookie, out string userName, out string password, out string authority)
{
authCookie = null;
userName = null;
password = null;
authority = null;
// Not using form credentials
return false;
}
}
}
