Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a code scanning method according to an embodiment of the present invention, where the present embodiment is applicable to a case where a two-dimensional code is scanned by using a client code scanning middleware, and the method may be executed by a code scanning apparatus, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in a computer device, as shown in fig. 1, where the method includes the following operations:
and S110, acquiring a two-dimensional code scanning request sent by the application client.
The application client can be used for scanning the two-dimensional code so as to process specific services according to the code scanning result. Optionally, the Application client may be a World Wide Web (Web) Application client, and may also be an APP (Application) type client, and the embodiment of the present invention does not limit the specific type of the Application client. The client scanning middleware can be middleware which is set for the application client and is used for assuming the code scanning function of the application client. Optionally, the client scanning middleware may be a type of software between the application system and the system software, and it uses the basic service (function) provided by the system software to connect each part of the application system or different applications on the network, so as to achieve the purpose of resource sharing and function sharing. The client code scanning middleware can rapidly access various new devices into the service system, simplifies the complexity of calling peripheral equipment for the upper layer of the service system, and the service system can complete corresponding service functions only by calling an Application Programming Interface (API) provided by the client code scanning middleware during development. The client code scanning middleware can be in communication connection with the application client so as to provide corresponding intermediate services for the application client. The two-dimensional code scanning request may be a request sent by the application client to the client scanning middleware, for requesting the client to scan the middleware for two-dimensional code scanning.
In the embodiment of the invention, the scanning function for the two-dimensional code is not executed by the application client any more, but is transferred to the code scanning middleware of the client for execution. Specifically, when the application client needs to scan the two-dimensional code, a two-dimensional code scanning request can be sent to the client scanning middleware.
Fig. 2 is a schematic diagram of an interface effect of an application client according to an embodiment of the present invention. In a specific example, as shown in fig. 2, a function option of "code scanning" may be provided in one of the display interfaces of the application client. When the code scanning function is triggered, the application client can send a two-dimensional code scanning request to the code scanning middleware of the client so as to indicate the code scanning middleware of the client to start to scan the two-dimensional code.
Optionally, the technical solution of the embodiment of the present invention may be applied to the following application scenarios: in the financial industry or the telecommunication industry, the application client is used for scanning codes to perform financial transactions and the like.
And S120, acquiring the information of the two-dimension code to be identified according to the two-dimension code scanning request.
The two-dimensional code information to be recognized may include user identity information or account information, and the like, for example, when a user performs a withdrawal operation, the user identity may be determined by scanning a two-dimensional code provided by a user client, so as to operate a corresponding user account. The embodiment of the invention does not limit the specific information content of the two-dimension code information to be identified.
In the embodiment of the invention, after the client code scanning middleware receives the two-dimension code scanning request, the client code scanning middleware can acquire the information of the two-dimension code to be identified according to the two-dimension code scanning request. For example, the client code scanning middleware can start a two-dimensional code scanning function to scan the two-dimensional code so as to acquire the information of the two-dimensional code to be identified.
It should be noted that the client code scanning middleware may obtain the information of the two-dimensional code to be identified through an inherent scanning device on a device installed in the application client, where the inherent scanning device may be a camera or another scanning module (e.g., an infrared scanning module), and the like. That is, the client code scanning middleware does not utilize extra code scanning hardware equipment to scan the two-dimensional code, so that the hardware cost of the two-dimensional code scanning is reduced.
S130, analyzing the information of the two-dimension code to be identified to obtain an analysis result of the two-dimension code.
The two-dimensional code analysis result may be a result of successful code scanning or failed code scanning, and in addition, the two-dimensional code analysis result may further include analysis data of the two-dimensional code scanning result, for example, when the two-dimensional code scanning fails, the two-dimensional code analysis result may further include an error code, error description data, and the like. The embodiment of the invention does not limit the specific data content of the analysis result of the two-dimensional code.
Correspondingly, after the client code scanning middleware acquires the two-dimensional code information to be identified, the two-dimensional code information to be identified can be analyzed, so that an analysis result of the two-dimensional code is acquired.
And S140, sending the analysis result of the two-dimensional code to the Internet of things platform.
The Internet of things platform can be an Internet of things management platform and can manage numerous Internet of things devices and various intelligent terminals.
In the embodiment of the invention, after the client code scanning middleware acquires the analysis result of the two-dimensional code, the analysis result of the acquired two-dimensional code can be sent to the Internet of things platform, so that the analysis result of the two-dimensional code is analyzed through the Internet of things platform, and the data acquired by analysis is applied to a specific real scene. For example, the internet of things platform may specifically apply the analyzed and obtained data to business scenarios such as transfer and bank account identification, so as to determine the code scanning success rate in the business handling process.
Therefore, the client scanning middleware is responsible for analyzing the two-dimensional code, so that the analysis result of the obtained two-dimensional code is sent to the Internet of things platform, the Internet of things platform can timely obtain the two-dimensional code scanning related data in the two-dimensional code scanning service scene and analyze and apply the two-dimensional code scanning related data, and the code scanning function is expanded.
According to the embodiment of the invention, the client scanning middleware is utilized to obtain the two-dimensional code scanning request sent by the application client, the information of the two-dimensional code to be identified is obtained according to the obtained two-dimensional code scanning request, the information of the two-dimensional code to be identified is analyzed to obtain the analysis result of the two-dimensional code, and the analysis result of the two-dimensional code is sent to the Internet of things platform, so that the problems of high hardware equipment cost, single code scanning function, low expandability and the like of the existing two-dimensional code scanning method are solved, the code scanning function of the two-dimensional code is enriched on the premise of not increasing the hardware equipment cost, and the expandability of code scanning application is improved.
Example two
Fig. 3 is a flowchart of a code scanning method according to a second embodiment of the present invention, which is embodied on the basis of the second embodiment, and in this embodiment, a specific optional implementation manner is provided for a client to scan a code in a code scanning middleware to obtain a two-dimensional code scanning request, obtain information of a two-dimensional code to be identified, and obtain an analysis result of the two-dimensional code. Accordingly, as shown in fig. 3, the method includes the following operations:
s210, receiving a two-dimensional code scanning request sent by an application client through a code scanning interface.
The code scanning interface may be an interface provided by the application client for the client scanning middleware, and optionally, the scanning interface may be a JavaScript interface of a web framework, or the like.
Specifically, when the application client needs to scan the two-dimensional code, for example, a "code scanning" function in the application client is triggered, the application client may send a two-dimensional code scanning request to the client code scanning middleware through the JavaScript interface. That is, the client code scanning middleware may receive, through the code scanning interface, a two-dimensional code scanning request sent by the application client.
And S220, starting the two-dimension code scanning device according to the two-dimension code scanning request.
The two-dimensional code scanning device can be a camera or other scanning module in the device for installing the application client. The client code scanning middleware scans the two-dimensional code by using the two-dimensional code scanning equipment in the equipment for installing the application client, so that the scanning equipment can be called quickly, and the hardware equipment cost of the scanning equipment can be reduced.
For example, assuming that the device for installing the application client is a banking system device, a camera in the device may meet the external device specification of a bank to access the system, and provide a data interface so that the upper layer application can call data.
Correspondingly, when the client code scanning middleware acquires the information of the two-dimensional code to be identified, two-dimensional code scanning equipment such as a camera in equipment for installing the application client can be called.
In an optional embodiment of the present invention, starting the two-dimensional code scanning device according to the two-dimensional code scanning request may include: the code scanning drive is called in a reflection mode, and the communication data are encrypted by using a content security application program interface of the application client; starting an MFC (Microsoft Foundation Classes) application according to a code scanning driving interface; and starting the two-dimensional code scanning device through the MFC application program.
Among other things, a content security application program interface (SecAPI) may be used to encrypt communication data. For example, in an application system of two-dimensional code scanning, after communication data is encrypted by using SecAPI, a background can automatically identify whether the content after code scanning is changed. Optionally, the background may use a Universal Unique Identifier (UUID) format to mark the content information obtained by scanning the code. Therefore, the data operation safety in the two-dimensional code scanning application can be improved by encrypting the communication data.
In an optional embodiment of the present invention, when the client code scanning middleware starts the two-dimensional code scanning device, the client code scanning driver may be called in a reflective manner, and the SecAPI of the client is used to encrypt the current communication data. The encrypted communication data may be data information obtained by scanning a two-dimensional code. By encrypting the communication data, the communication data can be effectively prevented from being tampered, so that the safety of the communication data in the communication process is improved. The client code-scan middleware may then launch the MFC application according to the code-scan driven driver interface called by the reflection. After the MFC application is started, the two-dimensional code scanning device is started through the MFC application.
In the foregoing solution, optionally, the driver interface may include a JNI interface, a C + + interface, and the like, and the embodiment of the present invention does not limit a specific interface type of the driver interface.
In an alternative embodiment of the present invention, the starting of the two-dimensional code scanning device by the MFC application may include: acquiring default scanning parameters of the two-dimensional code scanning equipment through an MFC application program; the default scanning parameters comprise a default camera identification and a default image resolution; and starting the two-dimension code scanning equipment according to the default scanning parameters, and scanning the two-dimension code to be identified through the two-dimension code scanning equipment.
The default scanning parameters are scanning parameters set by the two-dimensional code scanning device by default. Optionally, the default scan parameters may include, but are not limited to, a default camera identification, a default image resolution, and the like. The default camera identification can be used for identifying a default started camera. The default image resolution may be a default resolution set by the two-dimensional code scanning device.
In an optional embodiment of the present invention, after the MFC application is started, the MFC application acquires the default camera identifier and the default image resolution of the two-dimensional code scanning device, and starts the corresponding two-dimensional code scanning device according to the default camera identifier and the default image resolution, so as to complete scanning of the two-dimensional code to be recognized by the two-dimensional code scanning device. For example, the client code scanning middleware may send a command to turn on a camera to a device installed in the application client through a default camera id obtained by the MFC application. After receiving an instruction for starting the camera, the device installed on the application client determines the camera to be started, such as a front-facing camera of the device, according to the default camera identification, and starts the camera by adopting the default image resolution matched with the camera.
And S230, scanning the two-dimension code to be identified through two-dimension code scanning equipment.
Correspondingly, after the client scans the code middleware and starts the two-dimensional code scanning device, the two-dimensional code to be identified can be scanned through the two-dimensional code scanning device.
Specifically, after the client scans the code middleware and starts the two-dimensional code scanning device, information prompting the user to issue the two-dimensional code can be sent to the application client.
Fig. 4 is a schematic view of an interface effect provided in the second embodiment of the present invention for prompting a user to issue a two-dimensional code, and as shown in fig. 4, after the client scans a code middleware and successfully starts a two-dimensional code scanning device, the client may be notified to prompt the user to issue the two-dimensional code. At this time, the application client may display code scanning interface information as shown in fig. 4 in the display interface to prompt the user of a correct code scanning operation.
S240, acquiring the information of the two-dimensional code to be identified according to the scanning result of the two-dimensional code to be identified.
The two-dimensional code to be identified is also the two-dimensional code needing scanning identification.
Correspondingly, the client code scanning middleware can specifically take a scanning result of the two-dimensional code to be identified as the information of the two-dimensional code to be identified.
And S250, analyzing the information of the two-dimension code to be identified to obtain an analysis result of the two-dimension code.
In an optional embodiment of the present invention, analyzing the to-be-identified two-dimensional code information to obtain an analysis result of the two-dimensional code may include: image preprocessing is carried out on the two-dimension code information to be recognized; the image preprocessing comprises image deviation rectifying processing and two-dimensional code positioning processing; if the image preprocessing is successful, decoding the two-dimensional code information to be recognized, which is obtained after the image preprocessing; and taking the decoding processing result as the analysis result of the two-dimensional code.
The image preprocessing may be preprocessing operation performed on image content corresponding to the two-dimensional code information to be recognized. Optionally, the image preprocessing may include image rectification processing and two-dimensional code positioning processing. The image deviation rectifying process may be to adjust an image angle or an image position of the image corresponding to the two-dimensional code information to be identified obtained by scanning. The two-dimensional code positioning process may be used to position an identification position of two-dimensional code information to be recognized, for example, when positioning a QR (Quick Response) code in the two-dimensional code, geometric correction is required, and a basic method of geometric correction is to search 3 image-searching patterns of the QR code, determine four control points according to the image-searching patterns, and then correct an image using the four control points.
In the embodiment of the invention, when analyzing the to-be-identified two-dimensional code information, the to-be-identified two-dimensional code information (i.e. the image obtained by scanning the two-dimensional code) needs to be subjected to image rectification processing and two-dimensional code positioning processing. And if the image rectification processing and the two-dimension code positioning processing of the two-dimension code information to be identified are successful, the two-dimension code to be identified is decoded by using the processed two-dimension code information to be identified. And the result obtained by decoding is the analysis result of the two-dimensional code. The image deviation rectifying processing and the two-dimension code positioning processing in the image preprocessing enable the two-dimension code not to have an excessively high requirement on the position in the identification area, the identification flexibility of the two-dimension code is improved, and the probability that the two-dimension code cannot be identified is reduced.
In an optional embodiment of the present invention, after performing image preprocessing on the two-dimensional code information to be recognized, the method may further include: and if the image preprocessing is determined to fail, accumulating the image preprocessing time, and returning to execute the operation of image preprocessing on the two-dimensional code information to be recognized when the image preprocessing time is determined not to exceed the set time threshold value until the image preprocessing is determined to be successful or the image preprocessing time is determined to exceed the set time threshold value.
The set time threshold may be a total set time length of the image preprocessing, for example, the set time threshold may be 1 second or 5 seconds, and the like, and may be specifically set according to an actual requirement.
In the embodiment of the invention, a timeout mechanism can also be set for image preprocessing. That is, when image preprocessing is performed on the to-be-recognized two-dimensional code information, if it is determined that the image preprocessing fails, the image preprocessing time may be accumulated. And simultaneously, judging the accumulated image preprocessing time. If the current accumulated image preprocessing time does not exceed the set time threshold, returning to execute the image preprocessing operation again; otherwise, determining that the current accumulated image preprocessing time reaches a set time threshold. The timeout mechanism set for the image preprocessing can avoid entering a dead cycle of image preprocessing repeatedly performed on the information of the two-dimensional code to be recognized due to image preprocessing failure, so that code scanning failure is caused. Accordingly, if the image preprocessing is successful, the image preprocessing operation need not be repeatedly performed.
And S260, feeding back the decoding result of the two-dimensional code to the application client so that the application client displays the decoding result of the two-dimensional code in the application interface.
And the decoding result of the two-dimensional code is the result identified after the two-dimensional code is scanned.
In the embodiment of the invention, after the two-dimensional code scanning device successfully scans the two-dimensional code, the result obtained after scanning the two-dimensional code is returned to the application client through the code scanning middleware of the client, and the decoding result of the two-dimensional code is displayed in the application interface of the application client.
S270, sending the analysis result of the two-dimensional code to the Internet of things platform.
In an optional embodiment of the present invention, sending the analysis result of the two-dimensional code to the internet of things platform may include: sending the analysis result of the two-dimension code to a Software Development Kit (SDK) of the Internet of things platform; the SDK of the platform of the internet of things is arranged in the client code scanning middleware and used for receiving the analysis result of the two-dimensional code and sending the analysis result of the two-dimensional code to the platform of the internet of things through a Message Queue Telemetry Transport (MQTT).
The MQTT is a message protocol based on a publish/subscribe paradigm under the International Organization for Standardization (ISO) standard, and is a publish/subscribe model designed for remote devices with low hardware performance and under the condition of poor network performance.
Specifically, the client code scanning middleware can send the analysis result of the two-dimensional code to an SDK of an Internet of things platform built in the client code scanning middleware. After receiving the analysis result of the two-dimensional code, the SDK of the platform of the Internet of things can send the analysis result of the received two-dimensional code to the platform of the Internet of things through the MQTT.
In an optional embodiment of the present invention, when sending the analysis result of the two-dimensional code to the platform of the internet of things, the method may further include: acquiring equipment association information of two-dimensional code scanning equipment; and sending the equipment association information to the Internet of things platform.
The device-related information may be related information of the two-dimensional code scanning device, for example, the device-related information may be, for example, an identifier, operation information, fault information, and the like of the two-dimensional code scanning device, and the specific type of the device-related information is not limited in the embodiment of the present invention.

In the embodiment of the invention, except that the device association information of the two-dimensional code scanning device is actively acquired by the client code scanning middleware and sent to the Internet of things platform, the Internet of things platform can monitor and early warn the two-dimensional code scanning device. Optionally, the internet of things platform may also actively send an equipment monitoring request to the client code scanning middleware to request the client code scanning middleware to acquire equipment association information of the two-dimensional code scanning equipment, and feed the acquired equipment association information back to the internet of things platform.
In an optional embodiment of the invention, the internet of things platform is used for sending the analysis result of the two-dimensional code and/or the equipment association information to the data analysis application through the MQTT; and the data analysis application is used for carrying out data analysis according to the analysis result of the two-dimensional code and/or the equipment correlation information. The data analysis application can be used for sending equipment early warning information to the platform of the Internet of things when the fault information of the two-dimensional code scanning equipment is determined according to the data analysis result of the equipment correlation information.

Fig. 5 is a schematic flowchart of a two-dimensional code scanning method according to a second embodiment of the present invention. In a specific example, as shown in fig. 5, the two-dimensional code scanning method may specifically be: and opening a business interface of the web application client by the user for business handling. Specifically, a user can click a 'code scanning' button through an application client, and the application client can send an AJAX request to the client code scanning middleware through a JavaScript code scanning interface of the web application frame so as to instruct the client code scanning middleware to start two-dimensional code scanning.
And after receiving the AJAX request, the client code scanning middleware starts to reflect and call code scanning drive, and encrypts or decrypts the communication data by using SecAPI. Specifically, the code scanning middleware at the client can call a code scanning-driven JNI interface and a code scanning-driven C + + interface, and then start an MFC application program for code scanning preview through the code scanning-driven interface, so that the camera is started through the MFC application program with a default camera and a default resolution. At the moment, the camera used for scanning the two-dimensional code is started by the equipment installed on the application client, and after the application client detects that the camera is started, the relevant information of the two-dimensional code displayed by the client can be displayed on the display interface. After the customer presents the two-dimensional code, the camera can scan the two-dimensional code that the customer demonstrates in order to obtain the two-dimensional code information of waiting to discern, also obtains the scanning image of two-dimensional code. After the scanned image of the two-dimensional code is obtained, the client code scanning middleware can perform image rectification processing and two-dimensional code positioning processing on the scanned image of the two-dimensional code based on OpenCV, so that the processed scanned image of the two-dimensional code can meet the requirements of two-dimensional code identification and decoding. Then, the client code scanning middleware may decode the scanned image of the two-dimensional code using ZXing (barcode image processing library). If the decoding fails, the operations of image rectification, two-dimensional code definition and picture decoding are repeatedly executed within a set time threshold until the decoding succeeds or fails (the set time threshold is reached). After the two-dimensional code scanning process is finished, the client scanning middleware can send the decoding result of the two-dimensional code to a JavaScript code scanning interface of the web application client, so that the web application client displays the decoding result of the two-dimensional code in a display interface. Meanwhile, the client code scanning middleware can send the analysis result of the two-dimensional code to the SDK. The two-dimensional code analysis result can be a result of code scanning success or code scanning failure, and when the two-dimensional code scanning failure occurs, the two-dimensional code analysis result can also comprise error codes, error description data and the like.
The SDK further can send the two-dimensional code analysis result to the platform of the Internet of things in a mode of MQTT stacking. Meanwhile, the client code scanning middleware can also acquire the equipment association information of the camera in real time and send the equipment association information of the camera to the Internet of things platform so as to monitor and early warn the camera. Or, the internet of things platform can actively send an equipment monitoring request to the client code scanning middleware to request to acquire the equipment associated information of the camera. Correspondingly, the internet of things platform can send the analysis result of the obtained two-dimensional code and/or the device association information to the internet of things application SDK (software development kit) sent to the web back-end application layer in an MQTT (multi-query test) popping mode, so that the received data are analyzed through the internet of things application SDK, and the subscription event is processed according to the data analysis result. For example, if the internet of things application SDK determines that the camera has an equipment fault according to the data analysis result, fault early warning information of the camera is sent to the internet of things platform.
According to the technical scheme, the application client calls the client code scanning middleware through the interface to scan the two-dimensional code, and the communication data in the code scanning process is encrypted, so that the safety of the code scanning process of the two-dimensional code can be effectively improved. Meanwhile, the client-side code scanning middleware can send scanning results of the two-dimensional codes to the Internet of things platform in real time, so that two-dimensional code scanning equipment such as a code scanning process and a camera can be monitored and managed through an Internet of things application layer, upper-layer application supervision and further data development can be provided, the code scanning function of the two-dimensional codes is enriched, and the expandability of code scanning application is improved.
