声明类型中的网址是什么

Question

由于我想向应用程序中添加自定义声明，因此我检查了ClaimTypes的源代码（由JetBrains反编译器反编译）。这是其中的一部分：

namespace System.Security.Claims
{
  /// <summary>Defines constants for the well-known claim types that can be assigned to a subject. This class cannot be inherited.</summary>
  [ComVisible(false)]
  public static class ClaimTypes
  {
    internal const string ClaimTypeNamespace = "http://schemas.microsoft.com/ws/2008/06/identity/claims";
    /// <summary>The URI for a claim that specifies the instant at which an entity was authenticated; http://schemas.microsoft.com/ws/2008/06/identity/claims/authenticationinstant.</summary>
    public const string AuthenticationInstant = "http://schemas.microsoft.com/ws/2008/06/identity/claims/authenticationinstant";
    /// <summary>The URI for a claim that specifies the method with which an entity was authenticated; http://schemas.microsoft.com/ws/2008/06/identity/claims/authenticationmethod.</summary>
    public const string AuthenticationMethod = "http://schemas.microsoft.com/ws/2008/06/identity/claims/authenticationmethod";
    /// <summary>The URI for a claim that specifies the cookie path; http://schemas.microsoft.com/ws/2008/06/identity/claims/cookiepath.</summary>
    public const string CookiePath = "http://schemas.microsoft.com/ws/2008/06/identity/claims/cookiepath";
    /// <summary>The URI for a claim that specifies the deny-only primary SID on an entity; http://schemas.microsoft.com/ws/2008/06/identity/claims/denyonlyprimarysid. A deny-only SID denies the specified entity to a securable object.</summary>
    public const string DenyOnlyPrimarySid = "http://schemas.microsoft.com/ws/2008/06/identity/claims/denyonlyprimarysid";
    /// <summary>The URI for a claim that specifies the deny-only primary group SID on an entity; http://schemas.microsoft.com/ws/2008/06/identity/claims/denyonlyprimarygroupsid. A deny-only SID denies the specified entity to a securable object.</summary>
    public const string DenyOnlyPrimaryGroupSid = "http://schemas.microsoft.com/ws/2008/06/identity/claims/denyonlyprimarygroupsid";

我的问题是（但我希望这不太傻），URL的用途是什么？他们在其他地方使用吗？当我尝试打开URL时，我的浏览器说找不到该网站。因此，我认为没有xml模式或背后的东西。如果我添加了自定义声明，是否还必须添加类似这些URL的内容？

这些是ClaimTypes，代表实体可以声明的声明的预定义类型。您提到的来自WIF，这里是IdentityModel ClaimTypes。

已知的声明类型会自动反序列化到上下文中。Like http://schemas.microsoft.com/ws/2008/06/identity/claims/role被添加为user.roles集合的角色（用于IsInRole）。

因此，类型不是随机的，而是根据规范。您可以添加自己的类型。它可以是任何字符串，但也可以使用相同的格式。

假设您添加一个CustomerId作为声明，那么您需要通过claimtype="CustomerId"或您定义的uri（例如http://schemas.mycompany.com/2017/06/identity/CustomerId）查询Claims集合。

您可以通过代码或在Identity.Claims表中插入记录来添加声明。
