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.英国ITV开始根据英国女作家Val McDermid的破案小说Dr.Tony Hill中的故事"Mermaids Singing"和"Shadows Rising"改编的英国悬疑破案剧集。之后又由其他人续写，后来在第四季度第二集"Torment"又改编自Val McDermid的Dr.Tony Hill中的故事"The Torment of Others"。国内某大学奇葩学生郝帅，贾率既是关系很好的朋友，又是死党，生活中处处作对，又在关键时刻互相帮助，在大学里面他们遇到了各种奇葩的事情，两大奇葩又做出了让你啼笑皆非无人意料的事情。When we chat with the purchasing company, we often pay great attention to the content of the conversation and always say that there is no topic.

After many days, we often forget what we were talking about at that time, only remember when we had a good chat. In fact, the same is true for purchasing.
