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.
