Gateway apparatus and method for dynamically applying api settings

An API setting method of a gateway apparatus comprising a first rule table and a second rule table each storing API settings for processing the API request, and a reference flag setting a reference value indicating the rule table in which the API settings are stored to process the API request at a current time, among the first rule table and the second rule table, the method comprising:

• receiving, by a main processing unit of the gateway apparatus, new API settings from an API manager device;
• updating, by the main processing unit, the new API settings in a rule table other than the rule table corresponding to the reference value of the reference flag;
• setting, by the main processing unit, the reference value of the reference flag to a reference value corresponding to the updated rule table;
• and
• processing, by a sub-processing unit of the gateway apparatus, the API request based on API settings of the rule table corresponding to the reference value of the reference flag.

An API setting system comprising:

• at least one gateway apparatus mediating a communication linkage between a plurality of client terminals and a plurality of target servers, and managing API settings for processing an API request;
• and
• an API manager device providing the API settings to the gateway apparatus at a preset period,
• wherein the gateway apparatus comprises:
• a sub-processing unit processing an API request of a client terminal based on API settings through a plurality of sub-threads;
• a setting unit comprising a first rule table and a second rule table to store a set value for processing the API request, and a reference flag;
• and
• a main processing unit updating new API settings in a rule table other than the rule table corresponding to a reference value of the reference flag through a main thread when receiving the new API settings, and setting the reference value of the reference flag to a reference value corresponding to the updated rule table when the update is completed,
• wherein the setting unit comprises:
• the first rule table storing the API settings for processing the API request;
• the second rule table storing API settings different from those of the first rule table;
• and
• the reference flag setting a reference value indicating the rule table in which the API settings to be referenced by the plurality of sub-threads so as to process the API request at a current time are stored, among the first rule table and the second rule table.
