Finally, under normal circumstances, the processing capacity of our server is generally lower than that of the attacker. In view of this situation, there are currently the following methods: 1. Violent methods, such as setting an access frequency threshold, and rejecting when the number of accesses per IP unit time exceeds this threshold; For a certain service, if the instantaneous request is too large, choose to directly refuse to ensure the normal operation of other services; This method may result in normal users not being able to use it. 2. Verification code. In order to prevent normal users from being injured by exposure methods, at present, service providers will send verification codes to "users" when receiving a large number of requests. If it is a real user, it will input verification codes, but if it is a broiler, it will not. Through this method, the real user and the broiler will be distinguished.朴叙俊剧中饰演男主高东万（音译）一角，高东万学生时期是一个穿着跆拳道服的热血斗士，现在是一名平凡的合同制公司职员，他是一个为了能东山再起不再练跆拳道，开始挑战UFC选手的人物。In the waters east of Japan, 4 people were killed, 33 people were killed and only 11 were left.　　恰在此时，大女儿和二女儿家相继发生重大变故，孙妈妈经受不住沉重的打击，突发脑溢血瘫痪在床。三女婿在三年时间里，精心伺候孙妈妈，为她养老送终。丈母娘和女婿之间产生了浓浓的人间真情。********一个矮胖的副将军道：并非是栽赃陷害黎章，这也是为大局考虑。一个梦接着一个梦而来，却都是噩梦。
