我正在开发一个MVC 5互联网应用程序,并使用Identity 2.1.
这是我有的：
public void AddClaimToUser(string userName,string type,string value )
{
var AuthenticationManager = HttpContext.Current.GetOwinContext().Authentication;
var Identity = new ClaimsIdentity(userName);
Identity.AddClaim(new Claim(type,value));
AuthenticationManager.AuthenticationResponseGrant = new AuthenticationResponseGrant(new ClaimsPrincipal(Identity),new AuthenticationProperties { IsPersistent = true });
}
var identity = (ClaimsIdentity)User.Identity; IEnumerable<Claim> claims = identity.Claims;
提前致谢.
解决方法
首先,你必须在IdentityModels.cs类下创建一个添加声明的方法.就像这样,在下面的代码中我创建了一个对CompanyId的声明.
public class ApplicationUser : IdentityUser
{
public string FirstName { get; set; }
public string LastName { get; set; }
public bool IsActive { get; set; }
public int? CompanyId { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
var userIdentity = await manager.CreateIdentityAsync(this,DefaultAuthenticationTypes.ApplicationCookie);
userIdentity.AddClaim(new Claim("CompanyId",(this.CompanyId + "" ?? "0")));
return userIdentity;
}}
在编写上面的代码之后,您需要在IdentityConfig.cs中再编写一个方法
public static class IdentityExtensions{
public static int CompanyId(this IIdentity identity)
{
return Convert.ToInt32(((ClaimsIdentity)identity).FindFirst("CompanyId").Value);
}}
在此之后,只需输入即可在任何控制器中获取您创建的声明.
int companyId = User.Identity.CompanyId();
