我在 .Net Core 中使用 ReportExecutionServiceSoapClient 我获得了最新版本的 .net Core 并试图从报告服务中获取报告以使其工作。在使用 WCF 连接服务后,我可以添加如下所示的代码
// Instantiate the Soap client
ReportExecutionServiceSoap rsExec = new ReportExecutionServiceSoapClient(ReportExecutionServiceSoapClient.EndpointConfiguration.ReportExecutionServiceSoap);
// Create a network credential object with the appropriate username and password used
// to access the SSRS web service
string historyID = null;
TrustedUserHeader trustedUserHeader = new TrustedUserHeader();
ExecutionHeader execHeader = new ExecutionHeader();
// Here we call the async LoadReport() method using the "await" keyword, which means any code below this method
// will not execute until the result from the LoadReportAsync task is returned
var taskLoadReport = rsExec.LoadReportAsync(reportPath, historyID);
// By the time the LoadReportAsync task is returned successfully, its "executionInfo" property
// would have already been populated. Now the remaining code in this main thread will resume executing
string deviceInfo = null;
string format = "EXCEL";
// Now, similar to the above task, we will call the RenderAsync() method and await its result
var taskRender = await rsExec.RenderAsync(renderReq);
当它出现 renderAsync 时,所有的都崩溃了,因为服务的凭据没有在任何地方设置。我试图登录异步但没有成功。此外,我尝试使用 SetExecutionCredentialsAsync 设置凭据,但出现错误提示“HTTP 请求未经客户端身份验证方案‘匿名’授权。从服务器收到的身份验证 header 为‘NTLM’。”我不知道如何为 ReportExecutionServiceSoapClient 更改它。
我读过一些帖子,其中微软的人说使用 SOAP 的身份验证没有解决,但对我来说,这似乎是真的。我觉得我错过了一些东西。

如何验证此调用的用户身份?
最佳答案
我知道这是一个老问题,但我遇到了同样的问题并偶然发现了答案。
创建 ReportExecutionServiceSoap 对象后,您可以在 ClientCredentials 中指定用户名和密码。我使用 Basic 客户端凭据类型在此方面取得了成功。请确保您使用的是 HTTPS,否则您的密码将以明文形式发送到报告服务器。我还建议将用户/密码存储在安全的地方而不是代码。
BasicHttpBinding rsBinding = new BasicHttpBinding();
rsBinding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
rsBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
EndpointAddress rsEndpointAddress = new EndpointAddress("https://servername/ReportServer/ReportExecution2005.asmx");
var rsExec = new ReportExecutionServiceSoapClient(rsBinding, rsEndpointAddress);
rsExec.ClientCredentials.UserName.UserName = "username";
rsExec.ClientCredentials.UserName.Password = "pass";
