Method of limiting network flow through API gateway

Abstract

The invention discloses a method for limiting the network flow through an API gateway. The method comprises the following steps: A. the API gateway constructs a list data structure for a registered micro service; B. that API gateway configure a flow restriction policy for each micro service interface; C. constructing a current limiting filter module according to the current limiting strategy of the step B; D. The API gateway starts the current limiting filter module and decides whether to respond to the request of the terminal according to the output result of the current limiting module. In the method of the invention, by configuring the current limiting filter module and the current limiting strategy set, the API gateway can flexibly control the flow of the micro-service access accordingto the actual access situation of the user terminal, thereby completely meeting the complex requirements of the actual service.

Description

technical field [0001] The invention relates to the technical field of distributed systems of computer software, in particular to a method for restricting traffic through an API gateway. Background technique [0002] With the continuous deepening of the mobile Internet, more and more companies and enterprises have gradually begun to face the Internet, and migrate customer-oriented services and businesses online. When developing these online businesses, as the number of customers continues to increase, the structure of the business platform is also constantly changing and evolving. Gradually transforming from the early monolithic application architecture to the microservice architecture, clustering and distribution have also become standard technologies. [0003] In the process of building the basic platform of the microservice architecture, the API (Application Programming Interface) gateway is one of the essential core components. An API gateway provides a unified interfa...

Problems solved by technology

[0004] The API gateway can limit the access to the back-end micro-service interface, but the current solution in the industry is to use a counter. Every time the terminal accesses the micro-service interface, the count of the counter will be increased by one. When the count of the counter reaches Deny the user's access to the service when the preset threshold is reached

This current limiting method is relatively simple and cannot fully meet the complex needs of the business platform.
