Description
Technical Field
The present invention relates to the technical field of cross-local device control, and in particular, to a local device calling method, apparatus, storage medium, and device.
Background
At present, the mainstream enterprise management information system adopts more B/S (browser/server) architectures, and has higher advantages in deployment convenience and access usability. Based on the system with the framework, logic is compiled at a server side, when a user accesses the system through a browser, contents such as html webpage, js script, data form and the like are issued to the browser through an HTTP (hyper text transport protocol), the browser is responsible for operations such as page rendering, data display and the like, and all interactive operations of the user need to depend on the browser. Common browsers include IE, chord, FireFox, Safari, etc., and the business system can call related functions of the browsers by JavaScript scripts to implement front-end interactive operations, such as form data filtering and checking, dynamic interactive form submission, animation display effects, etc. But each browser has control over the system script code authority and is not allowed to operate the native hardware equipment.
In many service systems, various peripheral devices need to be synchronously controlled in service requirements, for example: controlling the label printer to print a receipt when the receipt is confirmed; the received invoice is output by a scanner and automatically submitted to a server; and when the applicant transacts the registration service, controlling the identity card reader to acquire the identity card information. These operational scenarios all require the use of a computer peripheral, while the browser itself does not provide the functional interface associated with interfacing with the peripheral. In order to realize the control of the system to the equipment (such as a scanner and a camera), the functions of the browser need to be expanded.
A common method in the prior art is to develop browser plug-ins, where different browsers have their own plug-in interfaces: IE supports ActiveX control technology based on COM mechanism, and Chrome, Firefox and Safari also provide respective plug-in technology. The peripheral control scheme based on the plug-in has the following problems: (1) the adaptability is low: each browser product has own plug-in specification, plug-ins need to be developed according to different browsers, at present, mainstream browsers include IE, Chrome, FireFox, Safari and the like, and if each browser is adapted, the development workload is huge. (2) The function is more limited: although the plug-in is local code, the plug-in still runs in the browser process and is restricted by various safety of the browser; (3) not easy to deploy: for example, an IE-based ActiveX control needs to implement a secure call interface and can be installed at a default security level after a trusted signature is added, an authority problem often occurs during installation, the security level of a browser needs to be manually adjusted, a detailed security control item and the like can be normally installed, a lot of operation and maintenance problems occur in a large-scale system, and a large amount of operation and maintenance workload is increased.

specifically, the browser forms a local device control instruction according to the format requirement of the message of the calling local device request in the predefined format of the desktop server, and sends the local device control instruction to the desktop server based on an HTTP protocol.
The HTTP protocol is a simple request-response protocol, which typically runs on top of TCP, that specifies what messages a client may send to a server and what responses to get. The headers of the request and response messages are given in ASCII code form; and the message content has a format like MIME (multipurpose internet mail extension type).
