Example 1

Fig. 1 is a flowchart of an OCX module calling method provided by an embodiment of the present invention, where the embodiment is applicable to the case of OCX module calling, the method may be performed by an OCX module calling device in the embodiment of the present invention, and the device may be implemented in a software and/or hardware manner, as shown in fig. 1, and the method specifically includes the following steps:

s110, receiving the CLASSID of the target OCX module sent by the display module.

It should be noted that, the OCX module calling method provided by the embodiment of the present invention is applied to a self-service terminal device, where the self-service terminal device includes: the OCX module calling method provided by the embodiment of the invention is executed by the QT agent module.

The display module may be a display module corresponding to any browser. The CLASSID is a unique identification of the OCX module.

The OCX module may be an OCX control.

Specifically, the display module corresponding to any browser sends the CLASSID of the target OCX module to the QT proxy module, and the QT proxy module receives the CLASSID of the target OCX module sent by the display module corresponding to any browser.

S120, initializing the target OCX module according to the CLASSID of the target OCX module.

Specifically, the method for initializing the target OCX module according to the class id of the target OCX module may be: the QT agent module creates a tool class object; the QT agent module initializes the OCX module corresponding to the CLASS ID based on the tool CLASS object.

S130, receiving a target event identifier and a display module identifier sent by a display module;

the target event identifier may be a name of the target event, or other identifiers used for representing the target event, and the display module identifier may be an address corresponding to the display module, or other identifiers used for representing the display module, which is not limited in the embodiment of the present invention.

And S140, sending the target event identification to the OCX module so that the OCX module generates a target event corresponding to the target event identification.

It should be noted that, the purpose of the QT agent module sending the target event identifier to the OCX module is to send the target event corresponding to the target event identifier to the QT agent module after the OCX module generates the target event corresponding to the target event identifier.

And S150, receiving the target event sent by the OCX module, and sending the target event to a display module corresponding to the display module identifier.

Specifically, the manner of receiving the target event sent by the OCX module and sending the target event to the display module corresponding to the display module identifier may be: inquiring a Slot function list according to the target event identification to obtain a target parameter type corresponding to the target event identification; generating a slot function according to the target event identification and the target parameter type; correlating the slot function with the target event identification; and calling a slot function to receive the target event and sending the target event to a display module corresponding to the display module identifier.

The QT agent module provided by the embodiment of the invention supports various OCX control method call and callback notification, summarizes OCX use scenes, designs a JS component to provide a universal and convenient call mode, and realizes the call communication between a browser page and a local OCX control program. The adopted technical scheme is that a Qt open source framework based on a universal WebSocket protocol and a C++ supports various browsers and windows systems of various versions. Compared with the prior art, the utility model has the advantages of improving the universality and the safety of the use scene.

Optionally, initializing the target OCX module according to the class id of the target OCX module includes:

creating a tool class object;

and initializing an OCX module corresponding to the CLASSID based on the tool class object.

The tool class object may be a QAxWidget object. It should be noted that, the QT proxy module provides a tool class qaxwidgets for calling the OCX module, and through this tool class, OCX module initialization, interface calling, and event callback notification can be implemented.

In one specific example, initializing the OCX module includes the steps of:

a QAxWidget object is created.

QAxWidget*ocx＝new QAxWidget(this)；

Initializing a control ClassId, and assuming that the control id is xxxx-xxxx-xxxx-xxxx-xxxxx.

ocx->setControl(QString::fromUtf8("{xxxx-xxxx-xxxx-xxxx-xxxxxxxx}"))。

Optionally, receiving the target event sent by the OCX module includes:

inquiring a Slot function list according to the target event identification to obtain a target parameter type corresponding to the target event identification;

generating a slot function according to the target event identification and the target parameter type;

correlating the slot function with the target event identification;

and calling a slot function to receive the target event.

Wherein, the Slot function list includes: the event identification and the parameter type corresponding to the event identification.

It should be noted that, the initialization of the OCX module and the interface call can implement dynamic call by using the setControl method and the dynamic call method provided by the QAxWidget, however, the asynchronous notification needs to define the corresponding event slot function in advance, and for the QT proxy module as a general proxy module, the notification event names and parameter types of different OCX modules cannot be known in advance, and the commonality of the QT proxy module cannot be implemented by directly using the QAxWidget, so a structure needs to be designed to implement the notification dynamic association of the OCX module. Class diagram design the core idea of this design is to dynamically bind asynchronous notifications to Slot objects through the QObject:: qt_meta () method and the QMetaObject:: connect () method as shown in fig. 2. Asynchronous notification association calls a connectidynamicosLOT method of an oxconnector object, the oxconnector object stores a notification list and a Slot function list, a Slot object (Slot function) is newly built for each event registering a notification callback, event signals are bound to the Slot object through QM eta object, and call functions send information of the event callbacks to a JS component through a WebSocket server.

In a specific example, dynamically invoking the OCX module includes the steps of:

after initializing the OCX module, it is assumed that the OCX module provides an add method and two parameters need to be entered, returning the result of the addition of the two parameters.

QVariant res＝ocx->dynamicCall("add(int,int)",1,2)；

Assuming that the OCX module sends an asynchronous notification msgCallBack, the asynchronous notification can be received and processed through the SLOT function SLOT of the QT proxy module.

A slot function is defined:

public slots:

void onMsgCallBack(QString&msg)；

the slot function is associated with an asynchronous notification.

connect(ocx,SIGNAL(msgCallBack(QString&)),this,SLOT(onMsgCallBack

(QString&)))；

Defining a slot function, and outputting data of asynchronous notification of the control:

void OcxObject::onMsgCallBack(QString&msg){

qInfo()<<"receive OCX msg"<<msg；}

optionally, the method further comprises:

receiving a target calling function corresponding to a target OCX module sent by a display module;

calling an OCX module according to the target calling function;

and receiving a calling result sent by the OCX module and sending the calling result to a display module.

Optionally, invoking the OCX module according to the target invoking function includes:

creating a tool class object;

and calling the OCX module according to the tool class object and the target calling function.

In a specific example, the OCX module general usage flow includes: firstly, initializing the controls, wherein each control has a unique ClassId which is equivalent to an identification card number registered to windows and is used for distinguishing different OCX modules. After initialization, the interface method provided by the OCX module can be called. The main calling scene is two, namely, the calling of the OCX module interface to acquire synchronous return and the calling of the interface to wait for receiving the OCX module asynchronous notification event. And synchronously using a scene, for example, calling an opening method of the indicator light control, and returning a result indicating light to be successfully opened by the control in real time. Asynchronous usage scenarios such as calling a ready to receive cash interface of a cash module, the OCX module asynchronously notifies the customer of receipt of a cash event after the customer has placed cash.

As shown in FIG. 3, the JS component needs to provide three package interfaces, namely, an initialization control, a method call and a notification callback. After connection is established, the JS component and the QT agent module send the three interfaces of an initialization OCX module, a calling interface and a notification callback to the QT agent program in a message form, and meanwhile, the connection management function of the WebSocket is realized internally, and the connection establishment, the message sending and the message receiving analysis are included. Among them, webSocket is a communication protocol that enables easier data exchange between a client and a server.

The JS and JavaScript are short for light-weight interpreted programming language, and are commonly used for browser script control writing.

Taking the number taking machine as an example to demonstrate the use process of the JS component, it is assumed that two hardware equipment OCX modules are provided, and the provided interfaces and events are shown in a table 1:

TABLE 1

1. The standby page initializes the id card reading device control.

ocxUtil.init(“{XXXXXXXX-XXXX-XXXX-0001}”)

2. The standby page calls an interface of the identity card reading device to enable the device to be in a ready state.

ocxUtil.invoke(“startIdCardReader()”)

3. The standby page registers an identification card reading event.

ocxUtil.regEvent("idCardReaded",idCardReadResult)

4. The user puts the identity card on the reading equipment, the equipment reads the chip information and sends an OCX notification event, the idCardReadResult function is called back by the agent program, the standby page obtains the chip information of the identity card through the function parameters, the server side transaction is called to generate queuing number information, and the queuing number information is jumped to the number printing page.

Function idCardReadResult(data){

idno=data; identity card number sent by the device for obtaining/obtaining

$. post ("getcustomumnber. Do", idNo, postCallbackFuc); generating queuing number information by/invoking server side transaction

}

5. The number printing page initializes the number printing device control.

ocxUtil.init(“{XXXXXXXX-XXXX-XXXX-0002}”)

6. The number printing page calls a number printing equipment interface and prints the number information generated by the server.

ocxutil. Invoke ("printNum (QString &)", printStr); the// printStr is the printing parameters.

In another specific example, the core of the embodiment of the invention is to write a QT agent program (QT agent module), which originally supports call and event monitoring of OCX control, and a browser supports WebSocket client connection, and the QT agent program supports WebSocket server building, so that the QT agent program interacts with pages. The whole structure is shown in fig. 4, and the call to the OCX module can be realized by providing a simple and easy-to-use universal JS interface through the structure shown in fig. 4. The JS and WebSocket are common technologies, and the browser is supported, so that the scheme has no special requirements on browser types and versions. The implementation key point of the embodiment of the invention is that firstly, an encapsulated object interface is provided for the browser to call the communication of the WebSocket server, secondly, the dynamic call of the OCX control is realized, the ID of each OCX control is different, the provided method is different from the name of the notification event, the dynamic call is required to be realized for the QT agent program, and the corresponding function is called through the parameters passed by the browser.

According to the technical scheme, the CLASSID of the target OCX module sent by the display module is received; initializing a target OCX module according to the CLASSID of the target OCX module; receiving a target event identifier and a display module identifier sent by a display module; the method comprises the steps of sending a target event identifier to an OCX module so that the OCX module generates a target event corresponding to the target event identifier; the target event sent by the OCX module is received and sent to the display module corresponding to the display module identifier, so that the problem that other browsers except IE cannot perform OCX call can be solved.
