The invention relates to a method and a system for uniformly processing multi-platform events. The method includes the steps: packaging variable definitions, process control and terminal characteristics in different system platforms to obtain user-defined macro language labels; performing hierarchy combination for the user-defined macro language labels according to the system platforms of the user-defined macro language labels, and establishing communication connection between combined user-defined macro language labels to form business events; detailedly analyzing all user-defined macro language labels in the business events when a translation request for an event of any system platform transmitted by the outside is received to obtain translation codes of any system platform of the request. Corresponding development technology limited by a plurality of technology platforms can be effectively shielded, an APP (application) developer only needs to know use conditions of current 'macro languages' and parameter configuration meanings, specific business logic functions can be combined in application development platforms by simply dragging the labels and matching parameters, and personalized requirements are met.
