在Asp.Net Core Controller中获取用户名

Question

What is the accepted way to get the username of a Asp.Net Core REST service inside of the controller? Assuming the authentication is done by JWT?

I see User.Claims.First().Value contains the username, but is it always going to be in the first claim?

Or is there some better way to access it?

Answer 1

You can use the FindFirst() function on the ClaimsPrincipal class.

Examples:

// using built in claim types
User.FindFirst(System.Security.Claims.ClaimTypes.NameIdentifier); 

// using custom claim type
User.FindFirst("username");
