失敗：試圖從ASP.NET調用外部Web服務返回一個401 - 的DefaultCredentials空
//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
作品：
//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
我怎樣才能使用ASP的identtity外部Web服務調用.NET的應用程序池？似乎沒有辦法將System.Security.Principal.WindowsIdentity.GetCurrent()轉換爲我可以用於此調用的東西。
謝謝！
