You're trying to run follow()on a ID, not the User object (as you probably want).
您试图follow()在 ID上运行，而不是在 User 对象上运行（如您所愿）。
This returns an integer:
这将返回一个整数：
$user1 = Auth::user()->id;
Maybe you want something like this:
也许你想要这样的东西：
$user1 = Auth::user();
$user2 = Input::get('id');
$user1->follow(User::find($user2));
Thanks to @blackpla9ue for the fix.
