ReportViewer中设置ServerReport.ReportServerCredentials属性的方法

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;

}

}
