全局获取当前用户ID功能

Question

I am using the MVC4 framework and in a lot of instances throughout the code I want to get the current user ID.

I understand to do this I can use:

  [InitializeSimpleMembership]
  public ActionResult SaveTask(FormCollection form)
  {
      var userID = WebSecurity.CurrentUserID;
  }

This works Correctly but I find myself having to put the [InitializeSimpleMembership] on every ActionResult . Ideally I would like a static function which I can call:

var userID = Utilities.CurrentUserID;

which is in a class called Utilities:

   public static Int32 CurrentUserID{

    get
    {
        return WebSecurity.CurrentUserID;

    }

  }

Note I know this will fail as WebSecurity will need the InitializeSimpleMembership Attribute but but I want to show by example what I want to achieve. Is this possible?

Answer 1

You can add the [InitializeSimpleMembership] to the top of your controller instead of for each action and can use WebSecurity.GetUserId(User.Identity.Name)

Or you can use

var userId = Membership.GetUser(User.Identity.Name).ProviderUserKey;
