Openstack Horizon(kilo)二次开发之匿名访问View

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>>

需要注意的是，这种方式不适用于class view.

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

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

给需要匿名访问的View设置属性public=True

setattr(view_func,'public',True)
