Method and device of modifying rule file

The invention relates to a method and a device of modifying a rule file. The method of modifying the rule file includes: after a rule-file modification request issued for a service system is received,generating a rule-file operation interface corresponding to the service system, wherein the rule-file operation interface includes selection items of all service logic corresponding to the service system; receiving service logic selected on the basis of the selection items of the service logic, acquiring the rule file, which corresponds to the selected service logic, according to a predeterminedassociation relationship of the service logic and the rule file, and generating a parameter input box corresponding to the selected service logic; and receiving rule parameters input in the parameterinput box, and modifying rule parameters in the acquired rule file on the basis of the rule parameters. According to the method, efficiency of modification of the rule file can be improved, modification operations are simple an
