需要注意的是，这种方式不适用于class view.

1. 修改horizon.base.require_auth:

   def require_auth(view_func):	    """Performs user authentication check.	    Similar to Django's `login_required` decorator, except that this throws	    :exc:`~horizon.exceptions.NotAuthenticated` exception if the user is not	    signed-in.	    """	    from horizon.exceptions import NotAuthenticated  # noqa	    @functools.wraps(view_func, assigned=available_attrs(view_func))	    def dec(request, *args, **kwargs):	        #此处添加一个判断，如果view_func的public属性为True则跳过认证.	        if getattr(view_func,'public',False):	            return view_func(request, *args, **kwargs)	        if request.user.is_authenticated():	            return view_func(request, *args, **kwargs)	        raise NotAuthenticated(_("Please log in to continue."))	    return dec

2. 修改horizon.base.require_perms:

   def require_perms(view_func, required):	    from horizon.exceptions import NotAuthorized  # noqa	    # We only need to check each permission once for a view, so we'll use a set	    current_perms = getattr(view_func, '_required_perms', set([]))	    view_func._required_perms = current_perms | set(required)	    @functools.wraps(view_func, assigned=available_attrs(view_func))	    def dec(request, *args, **kwargs):	        #此处添加一个判断，如果view_func的public属性为True则跳过认证.	        if getattr(view_func,'public',False):	            return view_func(request, *args, **kwargs)	        if request.user.is_authenticated():	            if request.user.has_perms(view_func._required_perms):	                return view_func(request, *args, **kwargs)	        raise NotAuthorized(_("You are not authorized to access %s")	                            % request.path)	    # If we don't have any permissions, just return the original view.	    if required:	        return dec	    else:	        return view_func

3. 给需要匿名访问的View设置属性public=True

   setattr(view_func,'public',True)
