The server stores a presentation device list and a document list in advance, and is also responsible for managing access rights of the mobile terminal, which may include: whether the user has access to the server, which presentation machines the user has access to, and presentation documents;
as shown in fig. 1, fig. 1 is a schematic flow chart of the method according to the embodiment of the present invention, which may specifically include the following steps:
step 101: a user accesses a server by using a browser built in the mobile terminal through a network;
step 102: after the server receives an access request sent by the mobile terminal, the server requests the mobile terminal to input a user name and a password, if the mobile terminal inputs a correct user name and a correct password, the authentication is passed, otherwise, the access is refused;
step 103: the server is pre-stored with a demonstration device list and a document list, and after the mobile terminal passes the verification, the mobile terminal selects demonstration devices for demonstration and files to be demonstrated from the demonstration device list;
step 104: the server pushes the file to be demonstrated selected by the mobile terminal to a demonstration machine connected with the selected demonstration equipment;
step 105: the method comprises the steps that a demonstration machine receiving a file to be demonstrated puts a file to be demonstrated pushed by a server into a cache, and relevant plug-ins are called to open the file according to the type of the file to be demonstrated;
step 106: the mobile terminal sends demonstration instructions such as document page turning, pause, stop, zoom-in, zoom-out, quitting and the like to the demonstration machine through an operation interface of the server;
step 107: the demonstration machine receives demonstration instructions such as page turning, pause, stop, magnification, reduction, quitting and the like sent by the mobile terminal through the server, and executes corresponding operations.
The demonstration method is realized by adopting a consignment type structure, and the demonstration machine consigns document display and control to a plug-in for realization. The presentation program provides initialization, network communication, and plug-in loading functions. The plug-ins enable the display and control of specific documents.
Plug-in components: the plug-ins are divided into external chain plug-ins and embedded plug-ins according to a display mode. The plug-in can be automatically loaded when the demonstration machine receives a document opening command sent by the server, the demonstration machine searches and verifies the dynamic link library file containing the plug-in under a specified directory, and the verified plug-in is stored in a plug-in list.
And data and command transmission is carried out between the presentation machine and the plug-in through a uniform interface standard. The plug-in must realize opening the core interface such as the file, closing the file, return information, etc., can also call the self-defining interface according to the standard. When the plug-in is loaded, the entrusting relation is set through the name of the interface, and the plug-in completes the functional operation in the realization of the interface.
Outer chain plug-in: the method comprises the steps that the external link plug-in opens and displays third-party operation software corresponding to a calling document, operation information of users is sent to a demonstration machine through a network, the demonstration machine calls an interface to forward the operation information to the plug-in, and the plug-in realizes operation on the document through an interface provided by the third-party software.
Embedding a plug-in: if the plug-in is the embedded plug-in, the plug-in is called and added to a system interface of a demonstration machine; the plug-in realizes a functional interface for operating the document and also provides a control, and the document content is displayed in a system interface.
