如何在ASP.NET标识中添加声明

假设您使用的是ASP.NET MVC 5项目模板,则添加声明的正确位置是ApplicationUser.cs.只是搜索Add custom user claims here.这将引导您进入该GenerateUserIdentityAsync方法.这是在ASP.NET Identity系统检索到ApplicationUser对象并需要将其转换为ClaimsIdentity时调用的方法.你会看到这行代码:

// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);

之后是评论:

// Add custom user claims here

最后,它返回身份:

return userIdentity;

因此,如果您想添加自定义声明,您GenerateUserIdentityAsync可能会看起来像:

// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);

// Add custom user claims here
userIdentity.AddClaim(new Claim("myCustomClaim", "value of claim"));

return userIdentity;

也许以下文章可以提供帮助:

var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, "Brock"));
claims.Add(new Claim(ClaimTypes.Email, "brockallen@gmail.com"));
var id = new ClaimsIdentity(claims,DefaultAuthenticationTypes.ApplicationCookie);

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