The invention discloses a business logic code generation method, apparatus and device, and a storage medium. The business logic code generation method includes the steps: respectively packaging a datasource, a logic operation and a data output channel into a visual data source component, a logic operation component and a data output channel component in advance for a user to select; acquiring a data source component, a logical operation component and a data output channel component selected by a user; receiving component parameters which are set by a user and correspond to the data source component, the logical operation component and the data output channel component; connecting the data source component, the logical operation component and the data output channel component according tothe operation of a user to form a flow chart; converting the flow chart into a character string corresponding to the flow chart; and analyzing the character string to generate a service logic code. According to the business logic code generation method, service logic code development is configured, modularized and visualized, and code development of most service scenes can be completed only through simple dragging operation of a user, and the underlying technology is shielded, and the development threshold is lowered, and development becomes easier and easier.
