Obtain the PID and application name of the occupied port in nodejs sub-process mode

Obtain the PID and application name of the occupied port in nodeJS sub-process mode, and distinguish between Windows and MAC environments

Give the user pId and pName and let the user decide whether to kill the process or tell the user what application is occupying the port
