Abstract

The application provides a data processing method and device, electronic equipment and storage medium. According to the executable file of the component of the application program, the class name of the class used by the application program in the component is obtained. According to the class name, the first offset address of the function name of the function used by the application program in the class in the executable file of the component is obtained. According to the first offset address of the function name in the executable file of the component, the function name is obtained. According to the class name of the class used by the application program in the component and the function name of the function used by the application program in the class, it is determined whether the call of the application program to the function used in the class used in the component is an illegal call. Through the application, in the case that the component of the application program is a compiled file, whether the call of the application program to the function used in the class used in the component is an illegal call can be quickly and accurately detected.
