The claims value provider allows binding a controller parameter to a claim that is associated with the current user, such a user ID, name, or email
<PackageReference Include="AspNetCore.ClaimsValueProvider.Fork" Version="2.0.0" />Configure the application to use the value provider.
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(options =>
{
options.ValueProviderFactories.Add(new ClaimsValueProviderFactory());
});
}In a controller action, use the FromClaim attribute, along with a claim type, to bind the parameter
public class MyController : Controller
{
[HttpGet("")]
public IActionResult Get(
[FromClaim(ClaimTypes.NameIdentifier)]Guid userId,
[FromClaim(ClaimTypes.Email)]string email)
{
...
}
}
