SQL injection – delayed injection / Python script blasting
Delayed injection Due to network problems and other reasons, if the timeout is too short, the blasting may be inaccurate, but if the timeout is set too long, the blasting time cost will increase. Principle Through the condition in if, if it is true, it will sleep, otherwise it will not sleep Here, the first […]
python concurrent programming (5)
Detailed explanation of IO model Blocking IO (blocking IO) In the blocking IO model, when a process needs to read data from a device (such as a hard disk), it must wait for the data from the device to be ready before it can continue execution. This waiting process is blocking because it prevents further […]
