The Graphical User Interface (GUI) is an interface display format for human-computer communication, allowing a user to manipulate icons or menu options on a screen using an input device such as a mouse to select commands, call files, launch programs, or perform other daily tasks.
Further, in this embodiment of the present application, the graphical interface data refers to data in the GUI, and includes: the GUI display method includes interface image data and interface information data, where the interface image data refers to screen data forming a GUI, such as interface layout data, interface style data, interface view data, and the like, and the interface information data refers to page data specifically included in the GUI, such as interface content data, interface layout data, and the like.
In an optional embodiment of the present application, the receiving graphical interface data transmitted by the host client includes: and establishing a data transmission protocol and a data transmission channel of the main client and the web server, and acquiring the graphical interface data transmitted by the main client according to the data transmission protocol and the data transmission channel.

As can be seen from the above, the slave client corresponds to the master client and is used for loading the graphical interface of the master client, it should be understood that in an actual business scenario, there may be a plurality of slave clients for loading the graphical interface of the same master client, for example, in an enterprise meeting scenario, enterprise a may be an initiator of a meeting, and enterprise B, enterprise C, and enterprise D may be participants of the meeting, so that the client of enterprise a may be a master client, and the clients of enterprise B, enterprise C, and enterprise D may be slave clients.

Wherein the query right can be obtained by querying whether the slave client has the right to access the corresponding master client of the encoded graphics data.
Based on the verification of the inquiry authority, the condition that some illegal clients steal the graphical interface data of the main client can be prevented, and the security of the graphical interface data of the main client is guaranteed.
Further, the querying, in response to at least one gui transmission request from the client, encoded gui data of the gui transmission request from the gui transmission module to obtain target gui data includes: and acquiring a request field of the graphical interface transmission request, and inquiring the coded graphical interface data of the graphical interface transmission request in the graphical interface transmission module by using an inquiry statement according to the request field to obtain target graphical interface data.

The interface layout logic refers to a connection relationship of target graphical interface data on a client display interface, for example, the connection relationship of a chart A and a chart B in the client display interface is nested, and the interface layout mode refers to a layout style of the target graphical interface data on the client display interface, for example, the layout style of the chart A in the client display interface is an oval shape. Further, the interface layout logic and the interface layout mode are obtained by querying a compiling environment of the host client corresponding to the target graphical interface data, and optionally, the compiling environment includes a myeclipse environment.
In an alternative embodiment, the interface generation tool is compiled from the Java language.
Further, the graphical transmission interface is returned to the slave client, so that graphical interface transmission between the master client and the slave client is achieved.
