当使用SSRS技术来布置报表,可能使用MS自带的ReportViewer控件来读取报表.
它分为Web和Windows两种版本;此处Web版.
ServerReport.ReportServerCredentials属性的类型为Microsoft.Reporting.WebForms.IReportServerCredentials,它可提供三种认证方式所需的证书(Credential):
1) Form认证证书(GetFormsCredentials);
2) 扮演认证证书(ImpersonationUser);
3) 网络认证证书(NetworkCredentials).
当报表的服务器端使用网络认证时,需要实现NetworkCredentials接口,而且必须将GetFormsCredentials()接口的返回值设置为False,否则会导致论证失败.
示例代码如下:
ReportViewer1.ShowCredentialPrompts = false;
ReportViewer1.ServerReport.ReportServerCredentials = new ReportSCredentials(userName, userPwd, userAD);
ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Remote;
public class ReportSCredentials : IReportServerCredentials
{
private string _UserName;
private string _PassWord;
private string _DomainName;
public ReportSCredentials(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
{
if (string.IsNullOrEmpty(_UserName) || string.IsNullOrEmpty(_PassWord))
{
return null;
}
else if (string.IsNullOrEmpty(_DomainName))
{
return new NetworkCredential(_UserName, _PassWord);
}
else
{
return new NetworkCredential(_UserName, _PassWord, _DomainName);
}
}
}
public bool GetFormsCredentials(out System.Net.Cookie authCookie, out string user, out string password, out string authority)
{
authCookie = null;
user = password = authority = null;
return false;
}
}
