Compared with resource consumption attacks, service consumption attacks do not require too much traffic. They mainly carry out accurate fixed-point attacks according to the characteristics of services, such as CC of the Web, retrieval of data services, download of file services, etc. Such attacks are often not aimed at congesting traffic channels or protocol processing channels. They are busy situations in which the server always handles high-consumption services and thus cannot respond to normal services. The detailed schematic diagram is as follows:The above is only a model of "Long En" bicycle, If you need to generate other types of bicycles, Other subclasses can be written. The most important advantage of factory mode is that some of the same methods can be implemented. We can write code in the parent class for these same methods. If we need to implement specific business logic, we can rewrite the parent class's methods in the subclass to implement our own business logic. In terms of professional terms, there are two points: First, weaken the coupling between objects and prevent code duplication. Instantiating a class in a method eliminates repetitive code. Second: Repetitive code can be written in the parent class. Subclasses inherit all member attributes and methods of the parent class. Subclasses only focus on implementing their own business logic.《吉祥如意年年来》是台湾华视2000年出品的一部国语和台语兼具的喜剧片，主要演员有张复建，廖峻，刘至翰，焦恩俊等。周家号称以武传家，当年家里有人在会稽出任军方高官，此人大王您应该是知晓的。炎黄郡是一个二次元的世界。甲、乙、丙、丁是“炎黄郡”里的名角，也是“生、旦、净、丑”继承人，唱、念、做、打，十八般武艺样样精通！四人向来形影不离、战无不胜，直到“炎黄郡”领袖兔爷寿诞当天，现场发生了离奇事件，并且甲、乙、丁三人从兔爷口中得到一个惊人消息，丙误服了“炎黄郡”禁药“维升素”而误闯入三次元世界“人间道”！兔爷命令甲、乙、丁三人在限期内奔赴“人间道”找回丙，否则药效失灵后将无法返回，而“炎黄郡”也将遭受灭顶之灾！于是三人带着使命来到“人间道”，结识了落魄音乐人时三作为三次元向导，在全新的世界展开了一段爆笑而惊悚的冒险生活！他们先后经历了被拍照而现出二次元真身，与时三组成虚拟乐队Dramaholic一夜爆红，同时甲遇见了一见钟情的漫画家阿秋，而阿秋的老板恰恰就是囚禁丙的神秘动画公司老板！错综复杂的故事背后，一个惊天大阴谋却在缓缓揭开面纱………,英布、蒲俊见状，急忙阻拦。赵王歇也淡淡道：广武君来晚了，大军已经出发和汉军发起激战了。
