And step 120, acquiring a control parameter corresponding to the identity information, and sending the control parameter to an operating system, wherein the control parameter is used for instructing the operating system to initialize the image acquisition device.
In particular, the control icon may implement the corresponding function because the control icon is previously associated with the trigger event. And when the control icon receives a control instruction sent by the user terminal, the control icon realizes a corresponding function according to the trigger event which is associated and bound in advance. Further, the trigger event includes a control parameter for implementing a specific function, for example, when the control icon corresponds to the image capture device call icon, the control parameter corresponding to the image capture device call icon may be data such as a flash parameter, a photo resolution parameter, and a camera mode parameter of the image capture device, and then the corresponding control parameter is sent to the operating system, the operating system is instructed to initialize the image capture device according to the received control parameter, and then the initialized image capture device is sent to the H5 page, so as to implement call of the image capture device in the H5 page.

Further, a preview area with a preset size may be configured in advance on the H5 page, and the preview area may be used to display image information acquired by the image acquisition device, and the like. Specifically, position information may also be included in the control parameter, and the position information may be used to position a specific position of the preview area in the H5 page, so that an image captured by the initialized image capturing device may be displayed in the preview area in the H5 page. Continuing with fig. 2, the image acquired by the image acquisition device is displayed in the preview area 210, and it should be noted that the size, shape and position of the preview area 210 are not limited, and may be set in a customized manner according to specific business requirements.

Further, the camera can be fully hosted in a page, such as the H5 page, much better than the system's own experience.
In one embodiment, acquiring a control parameter corresponding to the identity information and sending the control parameter to the operating system includes: acquiring a trigger event associated with identity information in advance; reading a control parameter corresponding to a trigger event; and packaging the control parameters by using a preset packaging algorithm, and sending the packaged control parameters to an operating system. Specifically, the trigger event may be associated with the control icon in advance, and the trigger event includes a control parameter for implementing a specific function. For example, the camera call control icon and the camera call trigger event may be associated and bound in advance, and the camera call trigger event includes device parameters for configuring the camera, for example, the device parameters may be flash parameters, resolution parameters, and the like of the camera, and then the device parameters are sent to the operating system to instruct the operating system to perform initial configuration on the camera according to the device parameters.

And then sending the encapsulated control parameters to an operating system, and analyzing the received encapsulated control parameters by the operating system so as to carry out initialization configuration on the image acquisition equipment by using the analyzed control parameters.
At the time of developing the H5 page, an area is reserved as a preview area of the camera. Specifically, the method for calling the camera in the operating system by the H5 page comprises the following steps: the page calls an operating system form through JS, control parameters such as the position of a preview layer of a camera, the size of the preview layer, a flash switch, photo resolution, a camera mode and the like are transmitted to the operating system in a JSON character string form, then the operating system analyzes the parameters packaged in the JSON character string form, initializes a self-defined camera according to the analyzed parameters, finally, the preview layer is superposed to an H5 page according to the position and the size defined by the parameters and can also be previewed, and the calling of the camera is realized in an H5 page.
Specifically, JSON is a format, and is a character string formed by splicing keys and values, and the character string is packaged in the JSON format, so that the control parameters are conveniently analyzed. Further, data transfer between the H5 page and the iOS operating system may utilize wkbwebview and H5 page for data transfer, specifically may be based on the following proxy method:
(void)userContentController:(WKUserContentController*)userContentController didReceiveScriptMessage:(WKScriptMessage*)message
specifically, the proxy method is triggered when an H5 page sends data to a terminal, where the message contains a JSON string delivered from an H5 page, and its specific form is as follows:
Figure BDA0002514672880000071
Figure BDA0002514672880000081
the JSON can be analyzed into a dictionary by using a method configured in advance in an operating system, and the specific meanings of the key and the value in the dictionary are as follows:
mode: camera mode, normal representing a normal camera, and scan representing a scan two-dimensional code mode. The default value is normal.
devicePosition: the lens direction, front denotes the front lens, and back denotes the rear lens. The default value is back.
flash: flashing, auto for auto, on for on, off for off, and torch for normally on. The default value is auto.
frameSize: shooting resolution, small represents 640x480, medium represents 1280x720, and large represents 1920x 1080. The default value is medium.
position: the coordinates and the size of the preview area, top represents the pixel of the preview area from the top of the screen, left represents the pixel of the preview area from the left of the screen, width represents the width of the preview area, and height represents the height of the preview area. The default values are: { "top": "0", "left": "0", "width": "0", "height": "0"}.
events: here are some callback events where camera initialization is complete or initialization fails.
The bindstop initialization is complete and this string is recalled to H5.
The binderror initialization fails and calls back this string to H5.
bindscancode successfully initializes the two-dimensional code pattern and calls this string back to H5.
bindinitdone successfully initializes the normal camera mode and calls this string back to H5.
It should be noted that the control parameters should include all parameters required for configuring the image capturing device, so that the operating system can accurately configure the image capturing device according to the received control parameters, and the operating system needs to analyze all the control parameters when receiving the encapsulated control parameters, so as to configure a camera with a relatively complete function.
In this embodiment, the control icon and the trigger event are associated and bound in advance, and the control parameter for implementing the specific function is stored in the trigger event in advance, so that the user can automatically execute the corresponding trigger event only by using the control icon without switching among a plurality of application programs, and the efficiency of implementing the specific service function in the page is improved. Furthermore, the control parameters are packaged according to the preset format, so that data transmission can be performed between different application programs through standard format data, and the function of data transmission between different application programs is further realized.
In one embodiment, reading the control parameter corresponding to the trigger event includes: generating an interface to be assigned according to a trigger event so that a user can assign values to the parameters to be assigned in the interface to be assigned; receiving assignment information of a parameter to be assigned in an interface to be assigned; and extracting the control parameters according to the assignment information.
Specifically, a parameter value corresponding to the control parameter may be set in advance in the trigger event, so that when a control instruction related to the control icon is received, the corresponding trigger event may be executed to send the parameter value in the trigger event to the operating system, so that the operating system configures the image capture device with corresponding performance according to the received parameter value. In another embodiment, when a control instruction about a control icon is received, a value assignment interface can also be generated, the interface to be assigned is pushed to a user terminal so that a user can assign values to the parameters to be assigned in the interface to be assigned, wherein the value assignment interface includes the control parameters to be assigned, and the user terminal can assign values to the control parameters in the value assignment interface to obtain parameter values and then send the parameter values to an operating system. In another embodiment, each control parameter may be associated and bound with the service database in advance, and when the control parameter needs to be assigned, only assignment information corresponding to the control parameter needs to be crawled from the corresponding service database in real time. It should be noted that, when the parameter value related to the control parameter is not found or received, the parameter value may also be assigned as a preset default value, and assigning the control parameter by using the preset default value may ensure that each control parameter is an effective parameter, thereby ensuring the integrity of the function of the initialized image acquisition device.
In this embodiment, the parameter assignment page is generated according to the control parameter, and then the parameter value input by the user terminal can be received, so that the user terminal can customize the parameter value, the configuration flexibility of the parameter value is improved, the parameter value is not required to be modified by the user through multiple jumps among multiple application programs, and the flexibility of parameter value assignment is improved.
In one embodiment, acquiring a control parameter corresponding to the identity information, and sending the control parameter to the operating system, where the control parameter is used to instruct the operating system to initialize the image acquisition device includes: acquiring basic parameters corresponding to the identity information, and sending the basic parameters to an operating system, wherein the basic parameters are used for indicating the operating system to initialize the acquisition performance of the image acquisition equipment; and acquiring a size parameter corresponding to the identity information, sending the size parameter to an operating system, and instructing the operating system to initialize the size of the image acquisition equipment by a size parameter user.
Specifically, the basic parameter may be a parameter for implementing a function of acquiring an image by the image acquisition device, such as a flash off parameter, a brightness parameter, a contrast parameter, and the like of the image acquisition device. The size parameter may be a size of the image capturing device, etc. Specifically, when the operating system receives the control parameters, the image capturing device with the corresponding performance is configured according to the basic parameters in the control parameters, and the image capturing device with the corresponding size is configured according to the size parameters in the control parameters.
Further, the operating system performs parameter analysis on the received encapsulated control parameters to obtain analyzed control parameters, extracts basic parameters and size parameters from the analyzed control parameters, and configures image acquisition equipment with corresponding performance and corresponding size according to the basic parameters and the size parameters. It should be noted that the size of the size parameter can be set by a user in a customized manner, for example, the size parameter can be equal to the size of a page, at this time, the image capture device can completely cover the H5 page, the size parameter can also be smaller than the size of the page, at this time, the image capture device does not completely cover the H5 page, when the image capture device does not completely cover the H5 page, a user can simultaneously perform other page operations in the page while using the image capture device, that is, the camera using the scheme does not need to occupy a full screen by the camera, developers and designers have more operation space, and the user experience is better.
In this embodiment, the control parameters include basic parameters and size parameters, so that the operating system can customize the basic parameters and the size of the image capturing device to obtain the image capturing device with the required performance and size.
In one embodiment, invoking the initialized image capturing device to display the image captured by the image capturing device in a page includes: extracting a position parameter from the control parameter; generating a preview area in the page according to the position parameter; and calling the initialized image acquisition equipment, and displaying the image acquired by the image acquisition equipment in the preview area.
Specifically, the position parameter may be a position coordinate, and after the operating system configures the image capturing device, the configured image capturing device is called in the H5 page and the image captured by the image capturing device is displayed in the preview area, specifically, a preview area is developed in the H5 page in advance, and the preview area is used for displaying the image information captured by the image capturing device or a user. In particular, reference may be made to fig. 2, which provides a front view of an image capture device called up in page H5, as well as fig. 3, which provides a side view of an image capture device called up in page. Specifically, the pages in the application program in the terminal may be stacked in a small view, where the H5 page is a view, and the camera preview area is also a view, for example, the H5 page may include the bottom view 200, a view corresponding to the preview area 210, and a view corresponding to the control icon area 220, and the camera preview area is overlaid on the H5 page, so that the function of calling the image capture device list in the H5 page is realized, specifically, the front view in fig. 2, and the side view in fig. 3.
With continued reference to fig. 2 and 3, H5 was developed using the HTML language and the JS language, and it is understood that a web page is developed with buttons for taking a picture, switching a flash, and the like. And the H5 developer writes a code communicating with the operating system in the click event of the button, and when a user clicks a button, the user tells the operating system the click event, for example, a takePho character string is transmitted to the operating system, the operating system receives the instruction and knows the requirement of the user for taking a picture, then calls the picture taking function of the camera to take a picture, stores the picture locally, and then calls the address back to the H5 page.
In the embodiment, different page areas are overlapped according to specific requirements, so that the self-definition of the page is realized.
In one embodiment, the method further comprises: generating an image preview instruction after acquiring the trigger information of the control icon; and sending the image preview instruction to an operating system, wherein the image preview instruction is used for instructing the operating system to search image information corresponding to the image identifier, packaging the image information and sending the image information to a preview area in a page for displaying.
