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;
        }

    }
