Question

失败：

//Note: webserviceProxy inherits from SoapHttpClientProtocol
//App Pool is running as a user with permissions to call the external webservice

var webserviceProxy = new webServiceProxy();

webserviceProxy.PreAuthenticate = true;
webserviceProxy.UseDefaultCredentials = true;

var returnVal = webServiceProxy.DoSomething();  //Fails with 401, webserviceProxy.Credendials shows an empty username, pass, and domain

使用：

//This code works, but I want to assign the current app pool's credentials to the webservice proxy's credentials.  UsingDefaultCredentials doesn't work.  The username, passoword, and domain are always null.

var webserviceProxy = new webServiceProxy();

webserviceProxy.PreAuthenticate = true;
webserviceProxy.Credentials = new NetworkCredential("user", "pass", "domain");

var returnVal = webServiceProxy.DoSomething();  //Fails with 401

如何使用ASP.NET应用程序池的标识进行外部Web服务调用？似乎没有办法将System.Security.Principal.WindowsIdentity.GetCurrent()转换为我可用于此次调用的内容。

谢谢！

也许这篇Microsoft支持文章可以帮助您解决问题：

You receive error 401.1 when you browse a Web site that uses Integrated Authentication and is hosted on IIS 5.1 or a later version

最重要的是，当机器名称和网站FQDN不匹配时，Windows将自行保护。

另见：

尝试从ASP.NET调用外部Web服务会返回401 - DefaultCredentials为空
