If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.

Among them, one of the more common attacks is CC attack. It simply and roughly sends a large number of normal requests, exceeding the maximum capacity of the server and causing downtime. What I encountered was a CC attack. At most, about 20 IP addresses around the world sent requests in turn, with the number of requests per address ranging from 200 to 300 times per second. When I read the log, I felt that those requests poured in like a flood. In the blink of an eye, there were a lot of requests. In a few minutes, the volume of the log file increased by 100MB. To tell the truth, this is only a small attack, but my personal website has no protection, and the server is still shared with others. This kind of traffic immediately goes offline.
