Abstract
The application provides a so file hook method, device and readable medium based on a loading program library, the method comprises the following steps: acquiring all loading path information of a so file and acquiring difference path information; establishing an interface for providing data of a storage path, storing the difference path information; establishing an interface for providing exclusion path data, and encapsulating the interface for providing data of the storage path and the interface for providing exclusion path data through a basic class; acquiring a function name to be hooked and a name of a replacement function; then finding the basic class to parse a so file related to the function to be hooked; judging that the so file related to the function to be hooked is running through a loading program database, and performing a hook operation, so that the so file to be hooked can be quickly found and excluded.
