如何验证WPF客户端请求ASP .NET的WebAPI 2 [英] How to authenticate WPF Client request to ASP .NET WebAPI 2

问题描述

我刚刚创建一个 ASP .NET MVC的Web 5 API 项目，并增加了实体框架模型和其他的东西得到它的ASP。 NET身份。

I just created an ASP .NET MVC 5 Web API project and added the Entity Framework model and other things to get it working with ASP. NET Identity.

现在我需要创建一个简单的身份验证请求，该API从WPF客户端应用程序在那里的标准方法。

Now I need to create a simple authenticated request to the standard method of that API out there from the WPF Client app.

ASP .NET MVC的Web 5 API code

[Authorize]
[RoutePrefix("api/Account")]
public class AccountController : ApiController

        // GET api/Account/UserInfo
        [HostAuthentication(DefaultAuthenticationTypes.ExternalBearer)]
        [Route("UserInfo")]
        public UserInfoViewModel GetUserInfo()
        {
            ExternalLoginData externalLogin = ExternalLoginData.FromIdentity(User.Identity as ClaimsIdentity);

            return new UserInfoViewModel
            {
                UserName = User.Identity.GetUserName(),
                HasRegistered = externalLogin == null,
                LoginProvider = externalLogin != null ? externalLogin.LoginProvider : null
            };
        }

WPF客户端code

public partial class MainWindow : Window
{
    HttpClient client = new HttpClient();

    public MainWindow()
    {
        InitializeComponent();

        client.BaseAddress = new Uri("http://localhost:22678/");
        client.DefaultRequestHeaders.Accept.Add(
            new MediaTypeWithQualityHeaderValue("application/json")); // It  tells the server to send data in JSON format.
    }

    private  void Button_Click(object sender, RoutedEventArgs e)
    {
        Test();
    }

    private async void Test( )
    {
        try
        {
            var response = await client.GetAsync("api/Account/UserInfo");

            response.EnsureSuccessStatusCode(); // Throw on error code.

            var data = await response.Content.ReadAsAsync<UserInfoViewModel>();

        }
        catch (Newtonsoft.Json.JsonException jEx)
        {
            // This exception indicates a problem deserializing the request body.
            MessageBox.Show(jEx.Message);
        }
        catch (HttpRequestException ex)
        {
            MessageBox.Show(ex.Message);
        }
        finally
        {               
        }
    }
}

好像它连接到主机和我得到正确的错误。这是确定的。

It seems like it is connecting to the host and I am getting the correct error. That is ok.

响应状态code并不表示成功：401

Response status code does not indicate success: 401 (Unauthorized).

这我不知道如何使用发送用户名和密码的主要问题WPF客户端...

The main problem that I am not sure how to send username and password using WPF Client...

（伙计们，我不是问我是否加密，并使用了API方法实现验证过滤器。我会做这个肯定后...）

(Guys, I am not asking whether I have to encrypt it and use Auth Filter over API method implementations. I will do this for sure later...)

听说我要在头请求中发送用户名和密码...但我不知道如何可以用做 HttpClient的客户端=新的HttpClient（）;

I heard that I have to send username and password in the header request... but I don't know how it can be done by using HttpClient client = new HttpClient();

感谢您的任何线索！

P.S。我已经取代的HttpClient 与 Web客户端，并使用任务（<一个href=\"http://stackoverflow.com/questions/10308938/unable-to-authenticate-to-asp-net-web-api-service-with-httpclient\">Unable与HttpClient的来验证的ASP.NET Web API服务）？

P.S. Have I replace HttpClient with WebClient and use Task (Unable to authenticate to ASP.NET Web Api service with HttpClient)?

推荐答案

您可以通过登录的用户，像​​这样的电流发送：

You can send over the current logged on user like so:

    var handler = new HttpClientHandler();
    handler.UseDefaultCredentials = true;
    _httpClient = new HttpClient(handler);

，那么你可以创建自己的授权过滤器

then you can create your own authorization filter

public class MyAPIAuthorizationFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(HttpActionContext actionContext)
    {
        //perform check here, perhaps against AD group, or check a roles based db?
        if(success)
        {
            base.OnActionExecuting(actionContext);
        }
        else
        {
            var msg = string.Format("User {0} attempted to use {1} but is not a member of the AD group.", id, actionContext.Request.Method);
            throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.Unauthorized)
            {
                Content = new StringContent(msg),
                ReasonPhrase = msg
            });
        }
    }
}

然后要确保在你的控制器每个动作使用[MyAPIAuthorizationFilter]

then use [MyAPIAuthorizationFilter] on each action in your controller that you want to secure.
