我正在采用building a OWIN login from a empty MVC的概念，我刚刚开始使用我的数据库添加该部分，在创建一个Identity声明放入URL后登录用户 .
这是我创建登录用户声明的代码
public class AuthenticationController : Controller
{
IAuthenticationManager Authentication
{
get { return HttpContext.GetOwinContext().Authentication; }
}
[GET("Login")]
public ActionResult Show()
{
return View();
}
[POST("Login")]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginModel input)
{
if (ModelState.IsValid)
{
if (input.HasValidUsernameAndPassword())
{
var identity = new ClaimsIdentity(new[]
{
new Claim(ClaimTypes.Name, input.Username),
},
DefaultAuthenticationTypes.ApplicationCookie,
ClaimTypes.Name, ClaimTypes.Role);
// if you want roles, just add as many as you want here (for loop maybe?)
if (input.isAdministrator)
{
identity.AddClaim(new Claim(ClaimTypes.Role, "Admins"));
}
else
{
identity.AddClaim(new Claim(ClaimTypes.Role, "User"));
}
// tell OWIN the identity provider, optional
// identity.AddClaim(new Claim(IdentityProvider, "Simplest Auth"));
Authentication.SignIn(new AuthenticationProperties
{
IsPersistent = input.RememberMe
}, identity);
return RedirectToAction("show", "authentication");
}
}
return View("show", input);
}
[GET("logout")]
public ActionResult Logout()
{
Authentication.SignOut(DefaultAuthenticationTypes.ApplicationCookie);
return RedirectToAction("Login");
}
}
这是我的Show.cshtml代码
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Details</h4>
<hr />
@Html.ValidationSummary(true)
<div class="form-group">
@Html.LabelFor(model => model.Username, new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Username)
@Html.ValidationMessageFor(model => model.Username)
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Password, new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.Password)
@Html.ValidationMessageFor(model => model.Password)
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.RememberMe, new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.EditorFor(model => model.RememberMe)
@Html.ValidationMessageFor(model => model.RememberMe)
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Login" class="btn btn-default" />
</div>
</div>
</div>
}
这是我的代码，我调用我的数据库并为登录用户存储我的数据
public class LoginModel
{
[Required]
public string Username { get; set; }
[Required]
[DataType(DataType.Password)]
public string Password { get; set; }
public bool RememberMe { get; set; }
public bool isAdministrator { get; set; }
public bool HasValidUsernameAndPassword()
{
bool result = false;
int countChecker = 0;
using (SqlConnection connection = new SqlConnection("server=server; database=db; user id=user; password=user"))
{
connection.Open();
using (SqlCommand command = new SqlCommand("SELECT count(*) FROM ACCOUNTS WHERE active = 1 AND UserName = @param1 AND PasswordField = @param2", connection))
{
command.Parameters.Clear();
command.Parameters.AddWithValue("@param1", Username);
command.Parameters.AddWithValue("@param2", Password);
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
for (int i = 0; i < reader.FieldCount; i++)
{
countChecker = Convert.ToInt32(reader[i].ToString());
}
}
if (countChecker > 0)
{
result = true;
using (SqlConnection connect = new SqlConnection("server=server; database=db; user id=user; password=user"))
{
connect.Open();
using (SqlCommand com = new SqlCommand("SELECT Administrator FROM ACCOUNTS WHERE active = 1 AND UserName = @param1 AND PasswordField = @param2", connect))
{
com.Parameters.Clear();
com.Parameters.AddWithValue("@param1", Username);
com.Parameters.AddWithValue("@param2", Password);
SqlDataReader read = com.ExecuteReader();
while (read.Read())
{
for (int i = 0; i < read.FieldCount; i++)
{
isAdministrator = Convert.ToBoolean(read[i].ToString());
}
}
}
connect.Dispose();
connect.Close();
}
}
else
{
result = false;
}
}
connection.Dispose();
connection.Close();
}
return result;
}
}
我的登录（LoginModel输入）完成并返回到Show.cshtml，然后在此处有一个例外@ Html.AntiForgeryToken（） . 我得到的例外是：
“http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier”或“http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider”类型的声明未提供的ClaimsIdentity . 要使用基于声明的身份验证启用防伪令牌支持，请验证配置的声明提供程序是否在其生成的ClaimsIdentity实例上提供这两个声明 . 如果配置的声明提供程序使用不同的声明类型作为唯一标识符，则可以通过设置静态属性AntiForgeryConfig.UniqueClaimTypeIdentifier来配置它 .
我是新手使用MVC，我无法分辨ActionResult Login（LoginModel输入）中缺少哪一个 . 有人可以向我解释我错过了哪一个 .
我将Corey的建议添加到了我的Global.asax中：
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.NameIdentifier;
AttributeRoutingConfig.RegisterRoutes(RouteTable.Routes);
}
}
现在我明白了：
其他信息：提供的ClaimsIdentity中没有“http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier”类型的声明 .
我更改了AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.NameIdentifier; to AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.Name;我没有任何例外 . 这是正确的语法吗？
