[0061] The above drawings show clear embodiments of the present disclosure, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0062] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0063] The scanning method of this embodiment can be applied to Figure 1 The application scenario shown in Figure 1 In the application scenario shown:

[0064] Communication can be established between the desktop computer 101 and the scanner 102 , and the user can control the scanner 102 to scan the object to be scanned (such as a voucher, etc.) through the desktop computer 101 to obtain a scanning result (such as an electronic version of the scanned voucher).

[0065] It should be understood that Figure 1 It is only used to exemplarily illustrate the application scenarios to which the scanning method of this embodiment can be applied, and should not be understood as a limitation on the application scenarios of the scanning method of this embodiment.

[0066] For example, in other embodiments, the desktop computer may also be a notebook computer, or a user device such as a mobile phone.

[0067] In the related art, scanning can be achieved in the following ways:

[0068] Method 1: The desktop computer 101 can store the scan result in the local disk of the desktop computer 101, and then transmit the scan result to the server (which can be a local server or a cloud server) through the local disk directory, such as entering the world wide web (web, also known as the World Wide Web) business system through the desktop computer 101, and finding the local disk directory through the control set in the web business system (such as the "upload button") to upload the scan result to the server.

[0069] Method 2: The desktop computer 101 uses the plug-in program (such as ActiveX control) of the IE browser to link the scanner 102, scans the object to be scanned to a specific directory (pre-configured directory) of the local disk, and then uses the file system object (File System Object, FSO) of ActiveX to find the scan result of the object to be scanned in the specific directory, and converts its format, such as converting it into a format based on 64 printable characters to represent binary data (Base64) and uploading it to the server.

[0070] However, the scanning process of the above method 1 is complicated. First, the scanning must be done separately from the web business system, and then the scanning must be done in the business process of the web business system. This is undoubtedly inefficient.

[0071] Using the above method 2 to implement scanning, because ActiveX is a unique object of the IE browser, the scanning business can only be operated in the IE browser, and because the current mainstream web framework runs better on browsers with Chrome and Firefox as the core, limiting the business functions to the IE browser will lead to a poor user experience. At the same time, the setting of enabling the ActiveX control of the IE browser is cumbersome and will also reduce the security level of the IE browser.

[0072] In order to avoid at least one of the above-mentioned technical problems, the inventors of the present disclosure, through creative labor, have obtained the inventive concept of the present disclosure: a scanning application (Scan App) and a scanning compatibility driver (Technology Without An Interesting Name, TWAIN) are respectively installed on the client, and a connection is established between the JavaScript program and the scanning application, so as to control the communication between the scanning application and the scanning compatibility driver through the JavaScript program, thereby realizing scanning.

[0073] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0074] See also Figure 2 , Figure 2 The figure is a schematic diagram of a scanning method according to an embodiment of the present disclosure, wherein the scanning method is applied to a client, and a scanning application and a scanning compatibility driver are running in the client.

[0075] like Figure 2 As shown, the method includes:

[0076] S201: Add a method library (scanner.js) to the client's system to be scanned.

[0077] The method library is determined based on the scanning compatibility driver, and includes: scanning methods, methods for setting scanning parameters, methods for displaying scanning results, methods for communication, and the like.

[0078] Exemplarily, the execution subject of this embodiment may be a scanning device, which may be a client, specifically a computer, a server, a terminal device, a processor, a chip, etc., which is not limited in this embodiment.

[0079] For example, when the scanning method of this embodiment is applied to Figure 1 In the application scenario shown in FIG. 1 , the scanning device may be as follows: Figure 1 Desktop computer shown.

[0080] From the above description, it can be known that the system to be scanned may be a web service system.

[0081] S202: Building a communication connection between the JavaScript program and the scan compatibility driver program based on the method library and the scan application.

[0082] The JavaScript program is a programming language program that runs on the client and is used to implement the scanning function.

[0083] The TWAIN protocol is a communication standard between software and image input devices such as digital cameras and scanners.

[0084] In the related art, a scanner is an electronic device (such as Figure 1 The desktop computer shown in the figure, etc.) directly uses JavaScript program to access and call the scan compatibility driver. Due to the security factors of the script itself, it is not allowed to directly access local resources. In this embodiment, a communication connection is established between the JavaScript program and the scan compatibility driver so that the scanner can be indirectly called based on the JavaScript program to achieve scanning.

[0085] That is to say, in this embodiment, by building a communication connection between the JavaScript program and the scan compatibility driver, the operation steps are simplified, and scanning and uploading are directly performed in the web business system. At the same time, it is no longer limited to the IE browser and its cumbersome setting operations, and it also avoids lowering the security level of the IE browser. While improving the compatibility of the IE browser, it also makes the operation of business personnel simpler and the business process more integrated.

[0086] S203: Controlling the scanner to scan the object to be scanned according to the communication connection, and obtaining a scanning result obtained by the scanner from scanning the object to be scanned.

[0087] Based on the above analysis, it can be known that an embodiment of the present disclosure provides a scanning method, which is applied to a client, and a scanning application and a scanning compatibility driver are running in the client. The method includes: adding a method library in the system to be scanned of the client, wherein the method library is determined based on the scanning compatibility driver, and building a communication connection between a JavaScript program and the scanning compatibility driver according to the method library and the scanning application, wherein the JavaScript program is a programming language program running on the client and used to implement the scanning function, and controls the scanner to scan the object to be scanned according to the communication connection, and obtains the scanning result obtained by the scanner when scanning the object to be scanned. In this embodiment, the following is introduced: running a scanning application and a scanning compatibility driver in the client, and building a communication connection between the JavaScript program and the scanning compatibility driver based on the scanning library and the scanning application by adding a scanning library, so as to "build a bridge" between the JavaScript program and the scanning compatibility driver, thereby realizing indirect calling of the scanner based on the JavaScript program, and then realizing the technical feature of scanning, avoiding the disadvantages of the complexity of scanning in related technologies, improving the efficiency of scanning, and avoiding the disadvantages of limited application scenarios, improving the universal applicability and compatibility of scanning, and improving the technical effect of security and reliability of scanning.

[0088] See also Figure 3 , Figure 3 is a schematic diagram of a scanning method according to another embodiment of the present disclosure.

[0089] like Figure 3 As shown, the method includes:

[0090] S301: Install a scanning application in the client.

[0091] It can be understood that regarding the technical features of this embodiment that are the same as those of the above-mentioned embodiments, this embodiment will not be repeated.

[0092] Exemplarily, this step can be understood as: in response to the user's click (such as double-clicking) operation on the scanning application icon (ScanApp.exe) and corresponding guidance operations (such as guidance operations from "Next" to "Finish"), completing the installation of the scanning application.

[0093] In other embodiments, a small program (Java applet) can be used to replace the scanning application.

[0094] S302: Install a scan compatibility driver in the client.

[0095] For example, in combination with Figure 1The application scenario shown is to start a desktop computer, which can specifically be to start the Windows operating system of the desktop computer, insert the driver CD of the scanning compatibility driver into the CD drive of the desktop computer, and the installation program will automatically start and output the corresponding configuration items on the output interface of the desktop computer. In response to the user's selection operation (such as a single click operation) for the setting item, the installation of the scanning compatibility driver in the client is completed.

[0096] S303: Add a method library to the system to be scanned on the client.

[0097] Among them, the method library is determined based on scanning the compatibility driver.

[0098] Combined with the above analysis, it can be known that the system to be scanned can be a web system. In this embodiment, in order to enable readers to have a deeper understanding of the implementation principle of the present disclosure, this embodiment takes the web system as the system to be scanned as an example to exemplarily illustrate the implementation principle of the present disclosure.

[0099] In this embodiment, by introducing a method library into the web system of the client, the JavaScript program can obtain the object to be scanned, thereby realizing the scanning of the object to be scanned.

[0100] There are different ways to add method libraries to a web system, for example:

[0101] Method 1: Download the method library on the client and add the method library to the web system through the entry text of the system to be scanned.

[0102] For example, in combination with Figure 1 In the application scenario shown, the method library can be downloaded in a desktop computer, and the web system includes an entry text, and the method library is introduced into the web system through the entry text.

[0103] For example, if the entry file is index.html, then the entry file index.html starts with <script src＝"scanner.js">的方式将方法库引入至web系统中。

[0104] 方法2：基于JavaScript程序的运行环境内置的软件包管理器(npm，node packagemanagement)在客户端安装方法库，并将方法库引入至待扫描系统。

[0105] 例如，以import"scanner.js"的方式将方法库引入至系统中。

[0106] S304：在扫描应用程序中部署扫描兼容性驱动程序的扫描库，并根据扫描库、扫描应用程序、以及扫描兼容性驱动程序封装得到对外提供服务的应用程序接口。

[0107] 应用程序接口(Application Programming Interface，API)是指，操作系统或应用软件留给程序的调用接口，程序通过调用应用程序接口从而使操作系统或应用软件去执行一些命令和动作。

[0108] 其中，本实施例对操作系统不做限定，例如，操作系统可以为Windows。且本实施例对浏览器也不做限定，例如，可以支持Chrome浏览器、Firefox浏览器、Edge浏览器、IE浏览器、360浏览器、以及百度浏览器等，此处不再一一列举。

[0109] 在一些实施例中，S304可以包括如下步骤：

[0110] 第一步骤：获取根据扫描应用程序与扫描兼容性驱动程序之间的交互信息，并获取扫描兼容性驱动程序的扫描属性信息。

[0111] 第二步骤：根据交互信息、扫描属性信息、以及扫描库封装得到应用程序接口。

[0112] 例如，在客户端安装了扫描应用程序之后，该扫描应用程序可自动静默部署基于扫描兼容性驱动程序的扫描库(该扫描库中包括与扫描相关的信息)，并对扫描兼容性驱动程序底层的交互行为(即交互信息)、属性设置(即扫描属性信息)进行封装，从而得到应用程序接口。

[0113] 其中，应用程序接口的数量可以为一个，也可以为多个，本实施例不做限定。应用程序接口可以通过引入方法库暴露的待扫描对象进行调用，从而实现扫描。

[0114] 在本实施例中，通过结合交互信息、扫描属性信息、以及扫描库封装得到应用程序接口，可以使得应用程序接口具有较高的调用性能，从而实现扫描的可靠性的技术效果。

[0115] S305：根据应用程序接口构建JavaScript程序与扫描兼容性驱动程序之间的通信连接。

[0116] 值得说明的是，在本实施例中，通过在扫描应用程序中部署扫描兼容性驱动程序的扫描库，并封装得到应用程序接口，以基于该应用程序接口作为JavaScript程序与扫描兼容性驱动程序之间的通信的"桥梁”，从而实现扫描的便捷性，提高扫描的效率的技术效果。

[0117] 在一些实施例中，S305可以包括如下步骤：

[0118] 第一步骤：根据应用程序接口建立扫描应用程序和方法库之间的连接。

[0119] 示例性的，在JavaScript程序中构建软件开发工具包，并根据软件开发工具包构建扫描应用程序和方法库之间的http连接。

[0120] 软件开发工具包(Software Development Kit，SDK)，一般是软件工程师特定的软件包、软件框架、硬件平台、操作系统等建立应用软件时的开发工具集合。本公开实施例中的软件开发工具包是指一个虚拟的程序包，其中包含一份做好的软件功能，其暴露的一些接口可以和外界联通。

[0121] 第二步骤：采用JavaScript程序控制扫描应用程序与扫描兼容性驱动程序之间的通信。

[0122] 示例性的，采用JavaScript程序调用待扫描对象，以控制扫描应用程序与扫描兼容性驱动程序之间的通信。

[0123] 例如，当首次访问集成了扫描控件的web网页时，在JavaScript程序中构建软件开发工具包的方法将自动初始化，即以http方式与扫描应用程序建立连接，连接成功后，就可以通过JavaScript程序调用待扫描(scanner)对象的方法控制扫描应用程序与扫描兼容性驱动程序之间的通信了，并可以调用应用程序接口来获取传输图像的数据，即传输待扫描对象的图像的数据。

[0124] 在本实施例中，通过构建软件开发工具包，以构建http连接，从而实现基于JavaScript程序控制扫描应用程序与扫描兼容性驱动程序之间的通信，进而实现扫描，以提高扫描效率，避免繁琐步骤的技术效果。

[0125] S306：根据通信连接控制扫描仪对待扫描对象进行扫描，并获取扫描仪对待扫描对象进行扫描得到的扫描结果。

[0126] 在一些实施例中，根据通信连接控制扫描仪对待扫描对象进行扫描，可以包括如下步骤：

[0127] 第一步骤：根据通信连接获取包括扫描仪的扫描源。

[0128] 第二步骤：响应于对扫描仪的选中操作，调用与扫描仪对应的扫描配置参数，并根据扫描配置参数控制扫描仪对待扫描对象进行扫描。

[0129] 例如，在扫描的准备阶段：列出扫描源，并确认扫描初始化工作是否成功，若是，则进入扫描阶段。

[0130] 在扫描阶段：传递扫描配置项(即扫描配置参数，如被用户选中的用于执行扫描操作的扫描源，又如扫描输出设置，还如扫描数据即扫描结果的存储方式等)，并通过扫描配置项执行扫描，当扫描结束后执行回调。

[0131] 在一些实施例中，在扫描结束后，用户可以通过控件"上一步"自定义函数””以获取扫描完成的状态，如果扫描发生错误，则可以通过客户端的输出界面输出提示错误信息。

[0132] 在一些实施例中，在扫描结束后，可以获取扫描结果，在基于预设存储方式的基础上对扫描结果进行格式处理，并对格式处理后的扫描结果进行存储。

[0133] 在一些实施例中，结合上述分析可知，可以设置扫描结果的展示的方式。相应的，可以将扫描结果放入JavaScript程序中的DOM标签中展示，也可以创建DOM标签承载扫描图像器，以便对扫描结果进行展示，本实施例不做限定。

[0134] 在一些实施例中，在扫描结束，得到扫描结果之后，可以将扫描结果上传至与台式电脑通信连接的服务器，以便对扫描结果进行归档。

[0135] 在一些实施例中，用户可以通过浏览器(浏览器的类型不做限定)进入web系统的扫描业务界面，操作相应的按钮控件，完成扫描流程。
