通过 WCF 的 SQL Server 报表服务器 (SSRS)：HTTP 请求未经客户端身份验证方案“Ntlm”

问题描述

我有一个 .Net Core 3.1 应用程序，它试图通过 WCF 连接到 sql Server 报表服务器，以便以编程方式按需生成报表。

但该程序无法对报表服务器进行身份验证。

这是相关的程序代码：

var binding = new BasicHttpBinding(BasicHttpSecurityMode.TransportCredentialOnly);
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
binding.MaxReceivedMessageSize = 10485760; //10MB limit

// Create the execution service SOAP Client
var rsExec = new ReportExecutionServiceSoapClient(
    binding,new EndpointAddress("http://my-ssrs/reportserver")
);

// Setup access credentials.
var clientCredentials = new NetworkCredential(
    "MyreportserverUserName","MyreportserverPassword","."
);
if (rsExec.ClientCredentials != null)
{
    rsExec.ClientCredentials.Windows.AllowedImpersonationLevel =
        System.Security.Principal.TokenImpersonationLevel.Impersonation;

    rsExec.ClientCredentials.Windows.ClientCredential = clientCredentials;
}


// ************************************************
// Get following Exception when next line executes.
// ************************************************
await rsExec.LoadReportAsync(null,"/path-to/my-report",null);

当执行最后一行（“rsExec.LoadReportAsync”）时，出现以下异常：

The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'NTLM'.

报表服务器位于同一个 Windows 域中。

经过一番研究，我尝试更改 ClientCredentialType = HttpClientCredentialType.Windows 但这产生了不同的异常，如下所示：

The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'NTLM'.

有人对我可以尝试的方法有什么建议吗？
