Client program plug-in method

The invention discloses a client program plug-in method, which comprises the following steps of: S1, separating a main program and functional programs of a client program, and dispersing the functional programs into plug-in packages; s2, starting a main program, initiating a plug-in package downloading request through a local application web side, and forwarding plug-in package information to a plug-in local management server side through a local gateway; s3, the plug-in local management server requests a plug-in background server to download the plug-in, and records the plug-in downloading speed and progress; and S4, after the plug-in is downloaded, starting a functional program of the plug-in. According to the client program, the functions are dispersed into the plug-in package, the size of an installation package is reduced, the plug-in function package does not need to be repackaged during upgrading, meanwhile, plug-in codes are isolated from main program processes, the influence of unrobust codes cannot
