SSRS Reportviewer-401未经授权

Question

我们正在将SQL Server报告从SQL Server 2008（SP3）计算机迁移到SQL 2012（SP1）计算机。报表在报表管理器中运行正常（即https://SQLRep2012/Reports）

但是，ASP.net应用程序返回“请求失败，HTTP状态为401：未经授权。”

我知道用户具有权限，因为我正在使用具有所有网络/ SQL服务器权限的管理员帐户对其进行测试。

查找下面的代码...

Answer 1

在发布上述问题之前，我已经找到答案了。麻烦来自网络凭证。以前我有这个。...

public System.Net.ICredentials NetworkCredentials
{
    get
    {
        System.Net.NetworkCredential nc = new NetworkCredential(_username, _password, _domain);
        CredentialCache cc = new CredentialCache();
        cc.Add(ReportServerUrl, "Negotiate", nc);
        return cc;
    }
}

但是，这不适用于我在SQL 2012上。我不得不将其更改为此。

public System.Net.ICredentials NetworkCredentials
{
    get
    {            
        return new NetworkCredential(_username, _password, _domain);
    }
}

Answer 2

创建没有域参数的NetworkCredential对我有用。

public System.Net.ICredentials NetworkCredentials
{
    get
    {            
        return new NetworkCredential(_username, _password);
    }
}
