Along with the continuous deepening of the informatization technology, the bank business processing also gradually realizes electronization, the business processing from accounting, classification to inquiry and the like basically replaces the traditional manual processing by a computer, but the authenticity inquiry of each business is mainly the manual inquiry of the original paper certificate, if the original paper certificate is made into an electronic image, the electronic image generated by the inquiry of the computer is used for replacing the manual inquiry of the paper certificate, the inquiry efficiency can be greatly improved, the labor intensity of people can be reduced, and the cross-region inquiry can be realized.
The client of the electronic image processing platform usually depends on reading and writing of an ACTIVEX control to a local file system, XML generation and the like, and enterprises can also develop the ACTIVEX control which is suitable for the requirements of the enterprises by using C + + language to meet more requirements. But for security and privacy protection reasons, except the unique IE browser under the Windows platform, the other browsers (such as firefox, chrome, etc.) do not support using ACTIVEX control and directly access operating system local files. Meanwhile, with the advance of paperless office of banks, the electronic image processing platform is taken as an important link, and the requirements for using the electronic image processing platform in different browsers are more and more increased.
Considering that if the original function can be replaced by the ACTIVEX control to realize reading and writing of the local file system, generating XML and the like, the electronic image processing platform is hopeful to be independent of the ACTIVEX control and has the capability of accessing the local file system by crossing browsers, and the applicability of the application is improved. Based on this, the embodiment of the specification provides a local file access system, a method, a device and an electronic device.
In order to better understand the inventive concept of the embodiments of the present specification, a local file access system of the embodiments of the present specification is first introduced. As shown in fig. 1, the local file access system may include a web client a1, a local transit server a2, and a local client A3. The files in the local file system a4 may be accessed through the local file access system. The local file system a4 may be used to store files on a local PC, such as pictures, documents, etc.
In some embodiments, the Web client comprises a Web Browser (Browser). The main function of the system is to present the Web resources requested by the user to the server and display the Web resources in a browser window.
The web client may be configured to respond to a triggered control click event, acquire a file operation instruction corresponding to the control click event, and forward the file operation instruction to the local transit server. Specifically, the web client is a medium for the user to interact with the local client. For example, the web client may provide a browser interface, and a user may perform operations on the browser interface, such as clicking, inputting, and the like, and in response to the operations of the user, the web client may execute corresponding instructions and feed back execution results to the user.
In some embodiments, the web client may include a page interaction module and a communication module, where the page interaction module is configured to trigger a control click event corresponding to a control based on the control clicked by a user on a browser interface, and obtain a file operation instruction corresponding to the control click event; the communication module is used for packaging the file operation instruction into a JSON character string in a custom format through a JavaScript plug-in; and sending the JSON character string to a local transit server through an HTTP (hyper text transport protocol). Specifically, the page interaction module adopts a JavaScript plug-in to complete development of a browser interface and a control click event, a user triggers generation of the control click event by clicking a control on the browser interface, then obtains a file operation instruction corresponding to the control click event, packages an instruction name and a transmission parameter of the file operation instruction into a JSON format and then calls a communication module, and the communication module sends a JSON character string to a local transfer server in an HTTP communication mode.
The instruction name corresponds to a file operation mode, the transmission parameter represents a path of a file, and different control clicking events correspond to different file operation instructions. For example, the browser interface may include a plurality of different controls, for example, an add-on control, a create-folder control, a copy-file control, and the like, based on a click of the controls by a user, a corresponding control click event may be generated, for example, if the user clicks the create-folder control, a file operation instruction corresponding to the create-folder control click event may be obtained, the file operation instruction may include an instruction name and a transmission parameter, the instruction name corresponds to a file operation mode, for example, if the user clicks the create-folder control, the instruction name may be CreateFolder, and the corresponding file operation mode is create folder. The transmission parameter represents a path of the file, and the path of the file may be a preset default path or a file path input by a user. Table 1 gives examples of some file manipulation instructions.
TABLE 1
Through the page interaction module and the communication module, the active exchange control can be replaced to generate the file operation instruction, so that corresponding operation can be conveniently performed on the local file in the local system, different browser generation file operation instructions can be supported by adopting JavaScript plug-ins to complete browser interfaces and control click event development, and the applicability of file operation is improved.
In some embodiments, the local transit server a2 may be configured to receive the file operation instruction, and provide the file operation instruction to a local client. The local transit server a2 may include a local file operation instruction and forwarding module, through which the receiving and forwarding of file operation instructions may be implemented.
In some embodiments, the local client a3 may be configured to obtain the file operation instruction from the local transit server, and parse the file operation instruction to obtain an instruction name and a transmission parameter; the instruction name corresponds to a file operation mode; the transmission parameter characterizes a path of the file; calling a file processing module corresponding to the instruction name to access a local file in a local file system according to the transmission parameter; and operating the local file according to the file operation mode.
Specifically, the local client may establish a communication connection with the local relay server, and the local relay server may provide the file operation instruction to the local client, and the local client may receive the file operation instruction. After receiving the file operation instruction, the local client can analyze the file operation instruction to obtain an instruction name and a transmission parameter, so that a file processing module corresponding to the instruction name can be called to access a local file in a local file system according to the transmission parameter, and the local file is operated according to the file operation mode.
In some embodiments, the local client connects to the local transit server through Socket; correspondingly, the local client is configured to obtain the file operation instruction from the local transit server through Socket connection. The Socket is an encapsulation for a TCP/IP protocol, and the Socket itself is not a protocol but a call interface (API), through which the TCP/IP protocol can be used. Socket connection is a long connection, and theoretically, once the connection is established between a client and a server, the client and the server cannot be actively disconnected; but may be disconnected due to various environmental factors, such as: when the server or client host is down, the network fails, or there is no data transfer between the two for a long time, the network firewall may disconnect the connection to release the network resources. Therefore, when there is no data transmission in a socket connection, a heartbeat message may also be transmitted between the local client and the local transit server to maintain the connection. The local transit server is connected through the Socket, the transmitted data are byte level, the transmitted data can be self-defined, the data volume is small, the data transmission time is short, the performance is high, and the method is suitable for information real-time interaction between the client and the server.
In some embodiments, the file processing module may include a picture processing module, an xml file processing module, and a document processing module; the picture processing module is used for processing picture files; the xml file processing module is used for processing an xml file; the document processing module is used for processing document files. Because the instruction name corresponds to a file operation mode, a proper file processing module can be selected according to the instruction name to realize access and processing of the local file. For example, if the instruction name obtained by the analysis is CopyFile, the file operation mode corresponding to the instruction name is a copy file, so that the document processing module can be selected to access and process the local file; if the instruction name obtained by the analysis is Threshold, and the file operation mode corresponding to the instruction name is to convert the picture into a black-and-white picture, the picture processing module can be selected to access and process the local file. Different file operation instructions are processed through different file processing modules, and the file processing efficiency can be improved.
In some embodiments, the invoking the file processing module corresponding to the instruction name to access the local file in the local file system according to the transmission parameter may include: finding out a function corresponding to the instruction name from an instruction array of a program and calling a corresponding file processing module; and accessing the local file in the local file system by using the operating system interface packaged in the file processing module based on the transmission parameter. Specifically, after the local client obtains the file operation instruction, the local client may analyze an instruction name in the JSON character string and find a corresponding file processing module related to function call from an instruction array of a program, then determine a path of a file based on the transmission parameter, and access the local file under the path of the file in a local file system using an operating system interface encapsulated in the file processing module, thereby operating the local file according to the file operation mode. By the method, different browsers can access the files in the local file system, and the application applicability is improved.
In some embodiments, the file operation mode may include image processing, reading and writing of configuration files, document encryption and decryption, and the like. Specifically, the specific contents of the file operation mode can refer to the description part in table 1 above. In the embodiment, a plurality of different file operation modes are provided, the requirement of a user on file operation can be met, and user experience is provided.
In order to better understand the local file access system provided by the embodiments of the present specification, a usage flow of the local file access system is introduced. As shown in fig. 2, the usage flow of the local file access system mainly includes the following steps.
User operation interface step: and the Web client receives a control clicking event triggered by a user through a JavaScript plug-in.
Acquiring a file operation instruction: and acquiring a file operation instruction corresponding to the control clicking event according to the control clicking event.
Forwarding the instruction to the local transfer service step: and the Web client encapsulates the file operation instruction into a JSON character string in a custom format through a JavaScript plug-in and sends the JSON character string to the local transfer server through HTTP.
Calling a client module according to the instruction: and analyzing the file operation instruction in the step, extracting an instruction name and a transmission parameter, and calling a file processing module corresponding to the instruction name through a local client.
And operating the local file: the file processing module called in the above steps uses the interface provided by the operating system to access the local file system to complete the file operation instruction.
The local file access system provided in the embodiment of the present specification may include: the web client is used for responding to a triggered control clicking event, acquiring a file operation instruction corresponding to the control clicking event, and forwarding the file operation instruction to the local transfer server; the local transfer server is used for receiving the file operation instruction and providing the file operation instruction to a local client; the local client is used for acquiring the file operation instruction from the local transfer server and analyzing the file operation instruction to obtain an instruction name and transmission parameters; the instruction name corresponds to a file operation mode; the transmission parameter characterizes a path of the file; calling a file processing module corresponding to the instruction name to access a local file in a local file system according to the transmission parameter; and operating the local file according to the file operation mode to solve the problem that a plurality of browsers do not support ACTIVEX controls to directly access the local file of the operating system, realize the capability of accessing the local file system under different browsers and improve the access efficiency of the local file system.
In order to further understand the local file access system provided in the embodiments of the present specification, a specific scenario example is described. As shown in fig. 3, the local file access system in this scenario example is applied to an electronic image processing platform, and taking a step of the electronic image processing platform converting a local image into a grayscale image as an example, the method mainly includes the following steps.
Stage B1, the user clicks the Add attachment button on the web interface, and invokes the local session box: and a user clicks an attachment adding button on a browser page to trigger an attachment adding control clicking event, the browser packages parameters into JSON character strings through an OpenFile method and sends the JSON character strings to a local transit server through an HTTP communication mode, and the JSON character strings are forwarded to a local client through the transit server. And the local client receives the JSON character string through Socket connection for analysis and calls a local session frame for selecting the image according to the OpenFile method name.
Stage B2, the user selects the processed image through the local dialog box: after the user selects the image to be processed in the local session frame, the local client packages the path of the image selected by the user into a JSON character string and returns the JSON character string to the browser through the transit server. After the browser analyzes the image path in the JSON character string, the src attribute of the < IMG > tag is assigned to the path so that the image can be displayed on the browser interface.
Stage B3, the user selects the operation of processing the image: the user can select image operations of turning black and white, turning gray scale, removing noise points, removing black edges and the like in the browser interface.
And a stage B4, performing gray level conversion processing on the local image: after a user selects a converted Gray image through a browser interface, the browser packages the selected picture path into a JSON character string through a Gray method, the JSON character string is sent to a local client through a transfer service in an HTTP communication mode, and the client calls an image processing module according to the parameter Gray and accesses a local file system to convert a target image into a Gray state according to the transmitted image path.
Stage B5, the browser reloads the image: and the local client returns the processing result to the browser through the transit server, and the browser reloads the image into the < IMG > tag according to the picture path.
The effect of the present scene example converting the local image into the grayscale image is shown in fig. 4.
Part D1: before the grayout button is activated, the image under the local directory is as shown in section D2. The image displayed by the interface is also read from the local directory.
Part D2: the image is displayed in the D1 section browser interface by reading the image path under the directory.
Part D3: after triggering the click event of "change gray", the image path of the selected image will be sent to the local client together with the "change gray" instruction, the local client will perform gray conversion on the file in the image path, and the image in the file directory after executing the instruction is as shown in part D4. And the browser reads the image under the D4 partial file directory again to display in the browser interface.
Part D4: after the "convert gray" event is triggered by section D3, the image under the file directory of section D2 is converted to a gray image.
In order to further understand the local file access system provided in the embodiments of the present specification, a specific scenario example is described. As shown in fig. 5, the local file access system in this scenario example is applied to an electronic image processing platform, and taking the electronic image processing platform to submit a picture as an example, the method mainly includes the following steps.
Stage C1, the user clicks the submit button on the web interface: and clicking a submission button through a browser interface by a user to trigger a submitted control clicking event.
Stage C2, determining whether there is a temporary upload directory: before submitting the files, the files need to be uniformly saved to a temporary uploading directory. The browser needs to confirm the existence of the temporary upload directory through the FileExists method. The transfer server forwards the FileExists method parameters and the directory path to the local client, and the client calls the document processing module to access the local file system to judge whether the temporary uploading directory exists.
Stage C3, creating a temporary upload directory: if the temporary uploading directory does not exist, the local client returns a parameter retContent of 0 to inform the browser that the directory does not exist. And after receiving the parameters, the browser calls a CreateFolder method to forward the target path of the temporary uploaded directory to the local client through the transit service. And the local client calls the document processing module to access the local file system and creates a temporary uploading directory according to the target path.
Stage C4, copying the file from the source directory to the temporary upload directory: and after the local client establishes the temporary uploading directory, the result is sent to the browser through the transfer service. To facilitate uploading, the upload file needs to be copied from the source directory to the temporary upload directory. The browser forwards the source directory path and the temporary upload directory path to the local client through the transit service by a CopyFolder method. The local client accesses the local file system to copy the file from the source directory to the temporary directory.
And a stage C5 of obtaining the file size of the temporary uploading directory: after the file to be uploaded is copied to the temporary uploading directory, the xml file generated in the stage C7 needs to contain the file size of the uploading directory. The browser forwards the upload directory path to the local client through the transit service via the GetFolderSize method. And the local client acquires the size of the directory file through the local file system interface.
And a stage C6 of acquiring file attribute information of the temporary uploading directory: the xml file generated in the C7 stage needs to obtain file attribute information in addition to the file size of the upload directory. The browser forwards the file directory to the local client through the transfer service by using a GetFileInfoList method to acquire the file attribute information and the size.
And a stage C7, generating an xml file according to the file attribute information and saving the xml file to a temporary uploading directory: an xml file for storing the information of the uploaded directory file is generated before the file is submitted from the local. The browser generates an xml character string according to the directory file size and the file attribute information acquired in the C6 stage and the C7 stage by a JavaScript native xml method, and then forwards the xml character string to the local client through a transit service by a SaveXml method. And the local client generates an xml file in the temporary uploading directory according to the received xml character string.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardbyscript Description Language (vhr Description Language), and vhjhd (Hardware Description Language), which is currently used by most popular version-software. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
From the above description of the embodiments, it is clear to those skilled in the art that the present specification can be implemented by software plus a necessary general hardware platform. Based on such understanding, the technical solutions of the present specification may be essentially or partially implemented in the form of software products, which may be stored in a storage medium, such as ROM/RAM, magnetic disk, optical disk, etc., and include instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the methods described in the embodiments or some parts of the embodiments of the present specification.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
The description is operational with numerous general purpose or special purpose computing system environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.
This description may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The specification may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
While the specification has been described with examples, those skilled in the art will appreciate that there are numerous variations and permutations of the specification that do not depart from the spirit of the specification, and it is intended that the appended claims include such variations and modifications that do not depart from the spirit of the specification.
