使用声明和AntiforgeryToken登录MVC 5 OWIN。我会错过索赔提供者吗？

Question

我试图学习MVC 5 OWIN登录的索赔。我尽量保持简单。我从MVC模板开始，插入了我的索赔代码（见下文）。我得到一个错误，当我使用@Html.视图中的AntiForgeryToken（）助手。

错误：

A claim of type 'http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier' or  
'http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovid    
er' was not present on the provided ClaimsIdentity. 

To enable anti-forgery token support with claims-based authentication, please verify that 
the configured claims provider is providing both of these claims on the ClaimsIdentity 
instances it generates. If the configured claims provider instead uses a different claim 
type as a unique identifier, it can be configured by setting the static property 
AntiForgeryConfig.UniqueClaimTypeIdentifier.

Exception Details: System.InvalidOperationException: A claim of type
'http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier' or 
'http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider' was 
not present on the provided ClaimsIdentity. To enable anti-forgery token

is providing both of these claims on the ClaimsIdentity instances it generates.

Source Error:
Line 4:      using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new 
{ id = "logoutForm", @class = "navbar-right" }))
Line 5:      {
Line 6:      @Html.AntiForgeryToken()

登录后操作

// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
    if (!ModelState.IsValid)
    {
        return View(model);
    }

    var claims = new List<Claim>
    {
        new Claim(ClaimTypes.Name, "Brock"),
        new Claim(ClaimTypes.Email, "[e-mail]")
    };
    var id = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);

    var ctx = Request.GetOwinContext();
    var authenticationManager = ctx.Authentication;
    authenticationManager.SignIn(id);

    return RedirectToAction("Welcome");
}

_逻辑部分。cshtml

@using Microsoft.AspNet.Identity
@if (Request.IsAuthenticated)
{
    using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
    {
    @Html.AntiForgeryToken()

    <ul class="nav navbar-nav navbar-right">
        <li>
            @Html.ActionLink("Hello " + User.Identity.GetUserName() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })
        </li>
        <li><a href="javascript:document.getElementById('logoutForm').submit()">Log off</a></li>
    </ul>
    }
}

我尝试设置索赔类型。名称标识符（如本SO答案中所示）

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

    AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.NameIdentifier;
}

然后我“只有？”得到这个错误

A claim of type 'http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier' was 
not present on the provided ClaimsIdentity.

我想保留antiforgeryToken，因为它可以帮助防止跨站点脚本。

抗真菌配置

解决此问题的一种方法是将AntiForgeryConfig设置为使用其他ClaimType。

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    WebApiConfig.Register(GlobalConfiguration.Configuration);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

    AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.Email;
}

添加NameIdentifier和IdentityProvider索赔类型

或者，您可以将Name标识符和标识符提供者声明类型添加到您的声明中。

List<Claim> _claims = new List<Claim>();
_claims.AddRange(new List<Claim>
{
    new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier", _user.Email)),
    new Claim("http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider", _user.Email)
})

Answer 2

您的索赔标识没有索赔类型。NameIdentifier，您应该在索赔数组中添加更多内容：

var claims = new List<Claim>
{
    new Claim(ClaimTypes.Name, "username"),
    new Claim(ClaimTypes.Email, "[e-mail]"),
    new Claim(ClaimTypes.NameIdentifier, "userId"), //should be userid
};

要将信息映射到索赔以获得更多纠正措施，请执行以下操作：

ClaimTypes.Name => map to username
ClaimTypes.NameIdentifier => map to user_id

由于用户名也是唯一的，因此您可以使用username来支持防伪令牌。

在应用程序\u Start（）中，指定要用作名称标识符的声明：

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        ...

        System.Web.Helpers.AntiForgeryConfig.UniqueClaimTypeIdentifier = 
            System.Security.Claims.ClaimTypes.NameIdentifier;

        ...
    }
}
