我正在设置一个 GenericPrincipal
,向它添加一个 GenericIdentity
和角色,但是当我尝试从中检索角色时,我什么也没得到。但是,如果我调用 Principal.IsInRole
,它会返回正确的值。
我错过了什么?
Example: https://dotnetfiddle.net/Uan3ru
var identity = new GenericIdentity("Test", "Test");
var pricipal = new GenericPrincipal(identity, new[] { "Role1", "Role2" });
var cls = identity.Claims
.Where(c => c.Type == ClaimTypes.Role)
.Select(c => c.Value);
foreach(var c in cls)
{
Console.WriteLine(c);
}
Console.WriteLine("complete");
最佳答案
在您的代码中,您将角色添加到 GenericPrincipal对象,而不是 GenericIdentity对象。
因此,身份对象没有任何关联的角色声明,而主体对象有。
从GenericPrincipal
获取角色
您应该能够像这样从 GenericPrincipal
对象中获取角色:
var identity = new GenericIdentity("Test", "Test");
var principal = new GenericPrincipal(identity, new[] { "Role1", "Role2" });
// We need to get the claims associated with the Principal instead of the Identity
var roles = principal.Claims
.Where(c => c.Type == ClaimTypes.Role)
.Select(c => c.Value);
Console.WriteLine("Roles associated with the GenericPrincipal:");
foreach(var role in roles)
{
Console.WriteLine(role);
}

从GenericIdentity
获取角色
如果您需要跟踪特定 GenericIdentity
对象的角色,您必须明确地将角色声明添加到实例中。然后,您可以像这样从身份对象中获取角色:
var roles = new[] { "Role1", "Role2" };
var identity = new GenericIdentity("Test", "Test");
// Explicitly add role Claims to the GenericIdentity
foreach (var role in roles)
{
identity.AddClaim(new Claim(ClaimTypes.Role, role));
}
Console.WriteLine(String.Empty);
Console.WriteLine("All Claims associated with the GenericIdentity:");
foreach (var claim in identity.Claims)
{
Console.WriteLine(claim);
}
关于.net - 无法从 GenericIdentity 检索角色,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/29834490/
