SSRS:ASP.NET中引用报表远程认证之ReportServerCredentials属性的设置

ReportViewer1.ServerReport.ReportServerCredentials这个属性需要一个接口实例。

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.

　　那么我们如何实现呢，Code如下：

[Serializable]
public class CustomReportCredentials : IReportServerCredentials
{
private string _UserName;
private string _PassWord;
private string _DomainName;
/// <summary>
/// 自动从web.config中读取信息
/// </summary>
public CustomReportCredentials()
{
_UserName = ConfigHelper.Get("ReportViewerUser");
_PassWord = ConfigHelper.Get("ReportViewerPassWord");
_DomainName = ConfigHelper.Get("ReportViewerDomain");
}
/// <summary>
/// 手动指定认证信息
/// </summary>
/// <param name="UserName"></param>
/// <param name="PassWord"></param>
/// <param name="DomainName"></param>
public CustomReportCredentials(string UserName, string PassWord, string DomainName)
{
_UserName = UserName;
_PassWord = PassWord;
_DomainName = DomainName;
}        public System.Security.Principal.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.                //1.若没有指定用户名和密码时，默认为本地认证
if (string.IsNullOrEmpty(_UserName) || string.IsNullOrEmpty(_PassWord))
return null;
else if (string.IsNullOrEmpty(_DomainName)) //2.若未指定域，则表示当前请求域
return new NetworkCredential(_UserName, _PassWord);
else //3.用户+域认证
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;            // Not using form credentials
return false;
}
}

调用方法如下：

ReportViewer1.ProcessingMode = ProcessingMode.Remote;
IReportServerCredentials irsc =new CustomReportCredentials("administrator", "xxxxxx", "xxxx");
ReportViewer1.ServerReport.ReportServerCredentials = irsc;
ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://192.168.0.1/ReportServer/");
ReportViewer1.ServerReport.ReportPath = "/test/report1";
