将ASP.NET Web API托管为Windows服务时如何获取用户名

Question

We are running a asp.net mvc application (client - this app is accessed through browser by user) which makes use of HttpClient class to make calls to asp.net web api application (server- I want to access the user information user. Person who invoked the client application). This is a intranet application. We are hosting asp.net web api as windows service. How can I get the user name in this scenario?

ApiController class has a property public IPrincipal User { get; } public IPrincipal User { get; } . I looked this property and this is what i got:

User.Identity.AuthenticationType = ""; User.Identity.IsAuthenticated = false; User.Identity.Name = ""

Is it possible to get some valid value from User.Identity with this kind of setup?

Answer 1

It depends on which user you want, the user running the website service / app pool (EG networkservice), or an authenticated user that logged into your website. Assuming you have the user logging in and auth set up in IIS, this might do to pass along the creds, which you could then extract in your API.

using (HttpClient httpClient = new HttpClient(new HttpClientHandler() { UseDefaultCredentials = true }))

Hard to say for sure without a whole bunch of details.
