Code injection method and device, storage medium and electronic equipment

The invention relates to a code injection method and device, a storage medium and electronic equipment, and belongs to the field of code injection.The method is applied to a terminal and comprises the steps that in response to injection configuration updating operation executed by a user based on a target application program, updated injection configuration information is determined, the injection configuration information comprises at least one target program and to-be-injected codes in one-to-one correspondence with the target programs; in response to the intercepted program execution notification, determining whether a second program matched with a first program corresponding to the program execution notification exists in the target program or not; under the condition that it is determined that a second program matched with the first program exists in the target program, a to-be-injected code corresponding to the second program is injected into the first program, so that the terminal executes the first pr
