這次我triying設置和獲取有關在前端用戶的全部信息，但我不知道whant我做錯了獲取完整的GenericPrincipal MVC從網絡API
我有兩個分開的項目第一個是Webapi項目，我正在使用它來爲用戶提供一個令牌。
// GET api/Account/ExternalLogin
[OverrideAuthentication]
[HostAuthentication(DefaultAuthenticationTypes.ExternalCookie)]
[AllowAnonymous]
[Route("ExternalLogin", Name = "ExternalLogin")]
public async Task<IHttpActionResult> GetExternalLogin(string provider, string error = null)
{
if (error != null)
return Redirect(Url.Content("~/") + "#error=" + Uri.EscapeDataString(error));
if (!User.Identity.IsAuthenticated)
return new ChallengeResult(provider, this);
ExternalLoginData externalLogin = ExternalLoginData.FromIdentity(User.Identity as ClaimsIdentity);
if (externalLogin == null)
return InternalServerError();
if (externalLogin.LoginProvider != provider)
{
Authentication.SignOut(DefaultAuthenticationTypes.ExternalCookie);
return new ChallengeResult(provider, this);
}
AppJobSeeker user = await UserManager.FindAsync(new UserLoginInfo(externalLogin.LoginProvider, externalLogin.ProviderKey));
bool hasRegistered = user != null;
if (hasRegistered)
{
Authentication.SignOut(DefaultAuthenticationTypes.ExternalCookie);
ClaimsIdentity oAuthIdentity = await UserManager.CreateIdentityAsync(user, OAuthDefaults.AuthenticationType);
ClaimsIdentity cookieIdentity = await UserManager.CreateIdentityAsync(user, CookieAuthenticationDefaults.AuthenticationType);
AuthenticationProperties properties = ApplicationOAuthProvider.CreateProperties(user.UserName, user.Id);
Authentication.SignIn(properties, oAuthIdentity, cookieIdentity);
}
else
{
IEnumerable<Claim> claims = externalLogin.GetClaims();
ClaimsIdentity identity = new ClaimsIdentity(claims, OAuthDefaults.AuthenticationType);
Authentication.SignIn(identity);
}
return Ok();
}
和客戶端是一個MVC 5項目中，我有一個方法來postasyn認證，另一個以創建AuthTickect這樣的...
public async Task<T> AuthenticateAsync<T>(string userName, string password)
{
using (var client = new HttpClient())
{
var result = await client.PostAsync((@"http://localhost:8060/Token"), new FormUrlEncodedContent(new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>(@"grant_type", @"password"),
new KeyValuePair<string, string>(@"userName", userName),
new KeyValuePair<string, string>(@"password", password)
}));
string json = await result.Content.ReadAsStringAsync();
if (result.IsSuccessStatusCode)
return JsonConvert.DeserializeObject<T>(json);
throw new ApiException(result.StatusCode, json);
}
}
private void CreateTicket(SignInResult result, SignInModel model, string returnUrl)
{
//Let's keep the user authenticated in the MVC webapp.
//By using the AccessToken, we can use User.Identity.Name in the MVC controllers to make API calls.
FormsAuthentication.SetAuthCookie(result.AccessToken, model.RememberMe);
//Create an AuthenticationTicket to generate a cookie used to authenticate against Web API.
//But before we can do that, we need a ClaimsIdentity that can be authenticated in Web API.
Claim[] claims =
{
new Claim(ClaimTypes.Name, result.AccessToken), //Name is the default name claim type, and UserName is the one known also in Web API.
new Claim(ClaimTypes.Email, result.UserName), //If you want to use User.Identity.GetUserId in Web API, you need a NameIdentifier claim.
};
//Generate a new ClaimsIdentity, using the DefaultAuthenticationTypes.ApplicationCookie authenticationType.
//This also matches what we've set up in Web API.
AuthenticationTicket authTicket = new AuthenticationTicket(new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie), new AuthenticationProperties
{
ExpiresUtc = result.Expires,
IsPersistent = model.RememberMe,
IssuedUtc = result.Issued,
RedirectUri = returnUrl,
});
//HttpContext.Response..User = principal;
//And now it's time to generate the cookie data. This is using the same code that is being used by the CookieAuthenticationMiddleware class in OWIN.
byte[] userData = DataSerializers.Ticket.Serialize(authTicket);
//Protect this user data and add the extra properties. These need to be the same as in Web API!
byte[] protectedData = MachineKey.Protect(userData, new[] { "Microsoft.Owin.Security.Cookies.CookieAuthenticationMiddleware", DefaultAuthenticationTypes.ApplicationCookie, "v1" });
//base64-encode this data.
string protectedText = TextEncodings.Base64Url.Encode(protectedData);
//And now, we have the cookie.
Response.SetCookie(new HttpCookie("JobSeekerAuth")
{
HttpOnly = true,
Expires = result.Expires.UtcDateTime,
Value = protectedText,
});
}
我的登錄方法看起來像
// POST: Account/SignIn
[HttpPost]
public async Task<ActionResult> Login(SignInModel model, string returnUrl)
{
if (!ModelState.IsValid)
return View(model);
try
{
CreateTicket(await WebApiService.Instance.AuthenticateAsync<SignInResult>(model.Email, model.Password), model, returnUrl);
return RedirectToLocal(returnUrl);
//return await WebApiService.Instance.AuthenticateAsync<SignInResult>(model.Email, model.Password) != null ? RedirectToLocal(returnUrl) : RedirectToLocal(returnUrl);
}
catch (ApiException ex)
{
//No 200 OK result, what went wrong?
HandleBadRequest(ex);
if (!ModelState.IsValid)
return View(model);
throw;
}
}
問題是，我想使用的GenericPrincipal在Razor視圖二送的用戶id或用戶名來回回登錄的用戶，當我試圖這樣做它給我什麼MO再比這裏令牌
@if (HttpContext.Current.User.Identity.IsAuthenticated)
{
<li>@Html.ActionLink("Sign Out", "SignOut", "Account")</li>
}
else
{...
所以，我不知道如何讓這個目標 祝商祺！......
