Gateway current limiting method and system based on user session Technical Field The invention relates to the technical field of computer correlation, in particular to a gateway current limiting method and system based on user session. Background The current prior art is often an interface level for gateway interface flow limiting strategies, such as flow limiting based on a frequency or token bucket algorithm for gateway interfaces (API), under the condition of traffic emergency, the flow rate may be increased by N times, if the common flow limiting algorithm is limited to interface level flow limiting, the situation that a part of interface requests are limited and the other part of interface requests are not limited under a series of continuous operation conditions of users occurs, and under the condition, the users may repeatedly refresh the flow rate, thereby causing flow rate amplification and finally resulting in poor user experience. Aiming at the defects, the application uses the LRU algorithm to sort the accesses of the users under the condition that the users have access records by multiplexing session and/or token mechanisms existing when the users log in, and combines the LRU algorithm to arrange the most possible access user sequence, thereby realizing gateway current limiting in an interface, avoiding flow amplification caused by the operation of individual users under the conditions of user refreshing and other operations, and improving the user experience.
