Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It is also to be understood that the terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items and includes such combinations.
As used in this specification and the appended claims, the term "if" may be interpreted contextually as "when", "upon" or "in response to a determination" or "in response to a detection". Similarly, the phrase "if it is determined" or "if a [ described condition or event ] is detected" may be interpreted contextually to mean "upon determining" or "in response to determining" or "upon detecting [ described condition or event ]" or "in response to detecting [ described condition or event ]".
In particular implementations, the mobile terminals described in embodiments of the present application include, but are not limited to, other portable devices such as mobile phones, laptop computers, or tablet computers having touch sensitive surfaces (e.g., touch screen displays and/or touch pads). It should also be understood that in some embodiments, the devices described above are not portable communication devices, but are computers having touch-sensitive surfaces (e.g., touch screen displays).
In the discussion that follows, a mobile terminal that includes a display and a touch-sensitive surface is described. However, it should be understood that the mobile terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and/or joystick.
Various applications that may be executed on the mobile terminal may use at least one common physical user interface device, such as a touch-sensitive surface. One or more functions of the touch-sensitive surface and corresponding information displayed on the terminal can be adjusted and/or changed between applications and/or within respective applications. In this way, a common physical architecture (e.g., touch-sensitive surface) of the terminal can support various applications with user interfaces that are intuitive and transparent to the user.
It should be noted that, in the related art, in order to implement a bidirectional call between a web page and a local system, an ActiveX control technology is used in an IE browser, and an NPAPI plug-in technology is used in browsers such as Chrome and FireFox. However, because of the problems of potential safety hazard and stability, activeX controls are no longer supported in Edge browsers newly introduced by microsoft corporation, and NPAPI plug-ins of Chrome browsers are also abandoned, so that many of the original services of scanner connection and drive realized by these technologies cannot be continuously used in new browsers. Furthermore, as business needs continue to iterate, browser plug-ins may continue to be updated, making many scanning devices incompatible with most or future potential browsers today.
Fig. 1 shows a flowchart of an example of a scanning device communication method according to an embodiment of the present application. The execution subject of the embodiment of the method of the present application may be a client, that is, a mobile terminal device having various software or browser configurations required to implement an image scanning function.
As shown in fig. 1, in step 110, the client obtains an image scanning request. Illustratively, the user may operate (e.g., click) on software or a browser to trigger the client to generate a corresponding image scan request.
In step 120, the client sends the registered scanning device information to the server based on the image scanning request, so that the server determines the target driving function corresponding to the registered scanning device information. Here, the registered scanning device information may be information of a scanning device that has been registered or installed at the client, which may contain information of a name, a type, and the like of the registered device. In addition, the server may determine an adapted drive function from the registered scanning device information.
In one example of an embodiment of the present application, a server may send registered scanning device information to a corresponding scanning device operator platform to obtain a corresponding target driver function from the operator platform. In another example of the embodiment of the present application, the server may pre-store driving functions for respective pieces of scanning device information, and may determine corresponding target driving functions through a retrieval operation.
In step 130, the client receives the target driver function from the server.
In step 140, the client establishes a communication connection with the scanning device based on the target drive function.
In some embodiments, the client may further send an image scanning instruction to the scanning device to drive the scanning device to perform an image scanning operation and generate corresponding image scanning electronic components. Further, the client receives the image scanning electronic part from the scanning equipment.
In the embodiment of the application, when receiving an image scanning request, a client is triggered to collect scanning device information registered locally and send the scanning device information to a server, and a driving function matched with the registered scanning device information is obtained in a cloud remote interaction mode, so that connection with scanning devices is realized. Therefore, when the plug-in of the browser cannot be compatible with the local scanning device, the target driving function received by the cloud can still be used for connecting the client and the scanning device, so that the local scanning device can be compatible with multiple browsers (for example, various browsers), and the scanning configuration operation is effectively simplified.
In some examples of embodiments of the present application, the server may determine the target drive function corresponding to the registered scanning device information by querying a dynamic link library. Here, the dynamic link library stores a plurality of scanning device information and corresponding driving functions, for example, corresponding driving functions for scanning device information of different operators and corresponding driving functions for different types of scanning devices of the same operator. Therefore, the server can find the corresponding target drive function in time through library query operation, and quick response can be realized. In addition, the dynamic link library can cover the driving functions corresponding to the scanning equipment information of all common operators, so that the universality of the scanning equipment is guaranteed.
Preferably, when update iteration occurs to the scanning device information of the operator, the scanning device information and the corresponding driving function may be updated in the dynamic link library, so that the scanning device range covered by the client may be conveniently increased.
In some application scenarios, during the process of registering the scanning device by the client, a corresponding scan recognition control (e.g., TWAIN control) may exist locally at the client, and the client may implement communication with the scanning device by invoking the scan recognition control. However, some browser plug-ins cannot support the scan recognition control, resulting in failure to invoke the scan recognition control to establish communication with the scanning device, and are incompatible with some scanning devices, resulting in a scan failure.
In view of the above, in some embodiments, with respect to step 140 described above, the client may invoke a scan recognition control authorized by the scanning device based on the target driver function to establish a communication connection with the scanning device. Therefore, even if the browser of the client does not have a plug-in compatible with the scanning device, the client can call the corresponding scanning identification control through the target drive function to establish communication connection with the scanning device, and can call the local scanning identification control across browsers and without barriers to realize interconnection communication with the scanning device.
Fig. 2 shows an architectural diagram of an example of a system suitable for applying the scanning device communication method according to an embodiment of the present application.
As shown in fig. 2, a server 210, a client 220, a print compatibility plug-in 230, and a scanner 240 may be provided in the system architecture. Here, the client 220 is configured with a TWAIN control that enables an interconnected communication with the scanner 240 by invoking the TWAIN control.
According to the embodiment of the application, the local TWAIN control can be driven by any version or type of browser to realize the corresponding image scanning function. Specifically, a print compatibility plug-in 230 may be installed on the client 220, the print compatibility plug-in 230 may support http services and websocket services, and may also invoke local TWAIN controls, for example, the print compatibility plug-in 230 may be configured by installing an application on the client that is operated or authorized by the server.
Further, the server 210 may also remotely update the print compatibility plug-in 230. Specifically, the client 220 may receive a plug-in upgrade package from the server 210 and update the print-compatibility plug-in 230 based on the plug-in upgrade package. Illustratively, the server may configure an http service that automatically updates the print compatibility plug-in 230 so that the print compatibility plug-in 230 may be automatically updated remotely.
During the process of communication configuration for the scanning device, the client may receive a user operation based on a locally configured browser plug-in to determine a corresponding image scanning request, for example, a user may perform an interactive operation on a corresponding control on a browser to generate an image scanning request. Further, based on the websocket protocol, the browser plug-in may send an image scanning request to the print compatibility plug-in 230 authorized by the server to drive the local TWAIN control to establish a communication connection with the scanner 240 through the print compatibility plug-in 230.
Specifically, when the browser needs to perform image scanning, the browser performs bidirectional communication with the print-compatible plug-in 230 through the websocket protocol, and sends an image scanning instruction to the print-compatible plug-in 230.
In response to the call request, the print compatibility plug-in 230 may call and load a function in a corresponding dynamic link library according to the registration information of the scanner 240 to drive the scanner 240 to perform an image scanning operation.
After completing the scanning, the scanner 240 may transmit the converted electronic file to the print compatibility plug-in 230.
After receiving the electronic file, the print compatibility plug-in 230 may perform a series of operations such as identifying, classifying, and storing locally on the file, and then notify the client of the local browser plug-in via the websocket protocol.
In response to the notification request, the browser plug-in may perform an upload archiving operation after reviewing the electronic file.
In the embodiment of the application, the browser plug-in can be in two-way communication with the printing compatibility plug-in through the websocket protocol, so that the high-concurrency scanning requirement of the browser can be met, and the aim of real-time response of a user can be fulfilled. In addition, the browser and the local TWAIN control are connected into a whole by adopting the websocket communication protocol technology, and compared with an ActiveX control and the like, the method can realize smaller memory occupation, can improve the operation efficiency and optimize the user experience.
According to the embodiment of the application, the dynamic link library in the cloud server is utilized, the compatibility problem among various browsers (such as Chrome, fireFox, opera, edge, safari and the like) can be thoroughly solved, the problem that various browsers cannot call a local TWAIN control to perform paper image scanning is perfectly solved, enterprise users have better user experience, configuration operation caused by browser version change can be omitted, and the configuration cost of a client is greatly reduced.
