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 audience at the back said it. . .In the above code, we use three functions, order500, order200, orderNormal to handle its own business logic, If the current own function cannot handle things, We pass it to the following function to handle it. By analogy, Until there is a function that can handle him, Otherwise, the responsibility chain mode will leave the chain directly, telling that it cannot be processed and throwing an error prompt. Although the above code can be used as the responsibility chain mode, we can see from the above code that the Order500 function depends on functions such as Order200, so there must be this function, which also violates the open-closed principle in object-oriented. Let's continue to understand writing flexible and detachable responsibility chain nodes.　　●说了多少回了,Typical plot: It's time for the promotion examination again.
