All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to obtain information collected by an external information collection device on a page of a browser which does not support an ActiveX control, the embodiment of the application provides an information collection result obtaining method, an information collection result obtaining device, information collection result obtaining equipment and an information collection result obtaining medium.
Example 1:
fig. 1 is a schematic process diagram of an information acquisition result obtaining method provided in an embodiment of the present application, where the process includes the following steps:
s101: and receiving an information acquisition result sent by the external equipment.
The method for acquiring the information acquisition result provided by the embodiment of the application is applied to the electronic equipment, and particularly, the electronic equipment is provided with application software which can realize the method for acquiring the information acquisition result provided by the embodiment of the application. The electronic device may be a Personal Computer (PC), a tablet computer, an intelligent terminal, a server, and the like, wherein the server may be a local server or a cloud server.
The electronic equipment can communicate with the external equipment and receive the information acquisition result sent by the external equipment. Specifically, the application software installed in the electronic device can communicate with the external device. The external equipment is used for information acquisition and is externally connected with the electronic equipment. Different types of external equipment can correspond to the same type of information acquisition results, that is, different types of external equipment can be used for acquiring the same type of information acquisition results. Or different types of external equipment can correspond to different types of information acquisition results, that is, different types of external equipment can be used for acquiring different types of information acquisition results. For example, the types of the external device include a card reading device and a scanning device, the card reading device can read card information (such as card information of an identity document, an entrance guard card, an attendance card, and the like), and the scanning device can scan information such as identity information or document information, and the like. Specifically, the external device may be a scanner, an id card reader, an IC card reader, a fingerprint device, a camera, or the like.
The electronic equipment can receive the information acquisition equipment through an interface of the external equipment. For example, the interface of the external device may be an Application Programming Interface (API) provided by the external device, or may be a hardware interface such as a Universal Serial Bus (USB) or a High Definition Multimedia Interface (HDMI).
In S101, the external device may actively or passively send an information acquisition result to the electronic device. Under the condition that the external equipment actively sends the information acquisition result to the electronic equipment, the external equipment can actively acquire the information and actively send the information acquisition result to the electronic equipment. Under the condition that the external equipment passively sends the information acquisition result to the electronic equipment, the electronic equipment can call an interface corresponding to the external equipment, control the external equipment to acquire information, and then the external equipment sends the information acquisition result to the electronic equipment.
S102: and sending the information acquisition result to the browser based on a websocket protocol.
The websocket protocol is a full-duplex communication protocol defined by hypertext markup language 5.0 (HTML 5), allows application software to actively push data (i.e., information acquisition results) to a browser, does not limit a browser kernel, and supports browser kernels such as IE, google, and firefox (firefox), so that communication between various kernel browsers and external devices can be realized. The hypertext Transfer Protocol (HTTP) Protocol is a unidirectional communication Protocol, and can only achieve acquisition of an information acquisition result according to a request sent by a browser, so that compared with the HTTP Protocol, the websocket Protocol can achieve bidirectional communication between the browser and an external device, and acquire the information acquisition result of the external device in real time.
The websocket connection is established between application software installed in the electronic equipment and the browser, and the application software and the browser can be in two-way communication, so that the browser can obtain an information acquisition result actively pushed by the external equipment through the application software.
According to the information acquisition result sent by the external device, the electronic device can actively push the information acquisition result to the browser based on the websocket protocol, so that the browsers of various kernels, especially the browsers which do not support ActiveX controls, can also obtain the information acquisition result acquired by the external device, and the universality of various kernel browsers is met. And the websocket protocol supports the two-way communication between the browser and the external equipment, so that the timeliness of acquiring the information acquisition result can be improved.
Example 2:
in order to improve flexibility of acquiring an information acquisition result, on the basis of the above embodiment, in this embodiment of the application, before determining an interface corresponding to identification information according to the identification information of an external device, the method further includes:
receiving an information acquisition request sent by the browser based on the websocket protocol, wherein the information acquisition request carries identification information of the external equipment;
determining an interface corresponding to the identification information according to the identification information of the external equipment;
and calling the interface to control the external equipment to acquire information.
Except for the implementation mode that the external device can actively push the information acquisition result to the browser, as shown in this embodiment, the electronic device can passively send the information acquisition result to the browser under the request of the browser, that is, by configuring various information acquisition result acquisition modes, the flexibility of information acquisition result acquisition can be improved.
Because the websocket connection is established between the application software installed in the electronic equipment and the browser, the browser can perform two-way communication, and therefore the browser can also send an information acquisition request based on a websocket protocol. The method comprises the steps that a user specifies an information acquisition result of a required type when using a page of a browser, so that the user can select an external device needing information acquisition in the page of the browser, and for the browser, after the browser acquires an operation of the user, an information acquisition request can be generated and identification information of the external device (namely the external device selected by the user) is carried in the information acquisition request.
The corresponding relation between the identification information of the external equipment and the interface is stored in the electronic equipment (or application software installed in the electronic equipment), so that the interface corresponding to the identification information can be determined according to the identification information of the external equipment carried in the information acquisition request. In one possible implementation, when each external device is installed, the identification information of the external device and the interface of the external device may be stored in the electronic device (or application software).
The electronic device (or application software) may call the interface corresponding to the identification information to control the external device to perform information acquisition, for example, the electronic device may schedule the interface to send a control instruction to the external device, and the external device performs a corresponding information acquisition operation (such as a scanning operation or a card reading operation) according to the received control instruction (such as a scanning instruction or a card reading instruction).
Taking the process of acquiring the information acquisition result shown in fig. 2 as an example, the embodiment of the present application is described, which includes the following steps:
s201: the browser sends an information acquisition request to the application software based on a websocket protocol.
For example, the information collection request may be a card reading request or a scanning request. The information acquisition request carries identification information of the external device.
S202: and calling the API of the external equipment by the application software to control the external equipment to acquire information.
The application software can determine the API corresponding to the identification information, i.e. the API of the external device, based on the identification information of the external device.
And when the information acquisition request is a card reading request, the application software controls the external equipment to read the card. And when the information acquisition request is a scanning request, the application software controls the external equipment to carry out scanning operation.
S203: and the application software acquires the information acquisition result of the external equipment.
S204: and the application software returns an information acquisition result to the browser based on the websocket protocol.
In the embodiment, the electronic device only needs to install one corresponding application software at most, and does not need to additionally develop and maintain the browser and the external device, so that the complexity of acquiring the information acquisition result is reduced, and the workload of developing and maintaining the browser and the external device can be reduced.
Example 3:
in order to improve timeliness of acquiring an information acquisition result, on the basis of the foregoing embodiments, in an embodiment of the present application, before determining an interface corresponding to identification information according to the identification information of an external device, the method further includes:
and establishing websocket connection with the browser.
In the websocket protocol, the application software and the browser can establish persistent connection and perform two-way communication only by completing handshaking once, and the application software can actively push the acquired information acquisition result to the browser, so that the timeliness of acquiring the information acquisition result is improved.
In one example, the browser may send a websocket connection establishment request to the application software, and the application software returns a websocket connection establishment response to the browser to complete a handshake, that is, complete establishment of the websocket connection between the application software and the browser.
