Below in conjunction with Fig. 5 to Fig. 7 description specifically introduce the plugin manager 210 control plug-in unit installation, update and
The operations such as unloading.
As shown in fig.5, being the main process figure of the board state control method the present invention is based on middleware card cage.
This method is based on above-mentioned middleware card cage.
Step S201, when client 2 is switched on, the plugin manager 210 in middleware unit 21 obtains in client 2
The plug-in unit of installation generates the first plug-in unit list.In the present embodiment, the first plug-in unit list is XML (Extensible
Markup Language, extensible markup language) formatted file.Acquired plug-in unit is stored in the first plug-in unit list
The information such as plug-in unit identifier and version number.
As shown in fig.6, in the present embodiment, a plug-in unit needs to beat using what client 2 provided after the completion of exploitation
Packing life is encrypted to plug-in applications (* .so files) and plug-in unit description information (* .json files) in packet Encryption Tool 10
It is uploaded to server-side 1 at encryption plug-in package (* .zip).The mark of plug-in unit is wherein contained in the plug-in unit description information of * .json formats
Know the essential informations such as symbol (classid), version (Version), encryption parameter (key, MD5).In installation, this is inserted Terminal Middleware
Before part, need to verify its legitimacy using above-mentioned plug-in unit description information.
The first plug-in unit list and state are obtained request and are sent to server-side together by step S202, plugin manager 210
1, and receive the second plug-in unit list corresponding with the first plug-in unit list of the return of server-side 1.In the present embodiment, described second
Plug-in unit list is XML format file, and the plug-in unit mark of the plug-in unit verified by server-side 1 is stored in the second plug-in unit list
It accords with and each passes through the status information of the plug-in unit of verification.The status information include, but are not limited to installation condition, more new state,
And unloaded state.For example, if the plug-in version number in the first plug-in unit list and newest version number in server-side 1 are inconsistent,
Then judge that plug-in unit needs to update (more new state).
In the present embodiment, the plugin manager 210 sends state to server-side 1 by HTTP POST modes and obtains
Request.When server-side 1, which receives the state, obtains request, school first is carried out to the plug-in unit identifier stored in the first plug-in unit list
It tests.For example, the verification includes：Verify whether the plug-in unit identifier stored in the first plug-in unit list is inserted with what server-side 1 stored
Part identifier is consistent.
If the plug-in unit identifier stored in the first plug-in unit list is consistent with the plug-in unit identifier that server-side 1 stores, sentence
Fixed verification passes through.If the plug-in unit identifier stored in the first plug-in unit list and the plug-in unit identifier that server-side 1 stores are inconsistent
(being not present in server-side 1 in the plug-in unit identifier stored in such as the first plug-in unit list) then judges that verification does not pass through.
When the plug-in unit identifier stored in the first plug-in unit list passes through verification, server-side 1 obtains the plug-in unit by verifying
Status information, and will by the plug-in unit identifier of the plug-in unit of verification and each pass through the status information of the plug-in unit of verification write-in the
Two plug-in unit lists, the second plug-in unit list of returning response the first plug-in unit list is to client 1, i.e., the second plug-in unit list is according to
