As shown in fig. 1, a first embodiment of the present invention provides a method for instruction interaction based on server parsing, which can be executed by a server, and includes at least the following steps:
s101, acquiring a request instruction sent by a request device.
In this embodiment, the requesting device may be a network-enabled hardware device such as a mobile phone, a personal computer, a tablet computer, and a PDA, or may also be a computer peripheral device such as a printer, a scanner, and a camera, which is not limited in this disclosure.
The requesting device and the server may perform data interaction through a local area network, a wide area network, and the like, which is not limited in the present invention. Preferably, the wide area network does not need to be repeatedly erected, the hardware cost can be reduced, and complicated network interconnection configuration is not needed.

S102, analyzing the request instruction based on a preset analysis service program to generate a standard instruction and returning the standard instruction to the request equipment, so that the request equipment executes corresponding operation according to the standard instruction, wherein the standard instruction comprises a bitmap instruction.
In this embodiment, the server does not need to install a driver, and when receiving the request instruction, the server parses the request instruction according to a preset parsing service program to generate a corresponding standard instruction and issue the standard instruction to the requesting device. The server only needs to support simple standard instructions, and complex request instructions do not need to be analyzed.
In this embodiment, when the requesting device receives the standard instruction, the corresponding operation may be performed according to the standard instruction: for example, when the requesting device is a PC, the requested content is displayed; storing the image data when the requesting device is a camera; when the requesting device is a printer, a document is printed, and so on.
The standard instruction is a simple control instruction and is suitable for terminal equipment supporting TCP/IP transmission control/network protocol. The bitmap instruction is a simple dot matrix data instruction, which is a vector composed of some binary bits, and includes a plurality of data control bits, including but not limited to picture format, position coordinates, picture width, picture rotation, magnification, font style, and the like. The bitmap instruction is simple in application control, and a request device supporting the protocol can be directly used. It is to be understood that the standard instruction may also be other standard instructions, which may be selected according to the actual situation of the requesting device, and is not specifically limited herein, but these schemes are within the protection scope of the present invention.
In the above embodiment, the request instruction sent by the request device is analyzed into the standard instruction based on the preset analysis service program and returned to the request device, so that the server can avoid the installation of drivers of different products and different machine types, the flexibility and the reusability of the server are improved, and the request device can also avoid the instruction support development, thereby reducing the development difficulty and the hardware cost of the device.
On the basis of the above embodiment, in a preferred embodiment, the requesting device is a printer, and the request instruction includes request instruction content and printing control parameters.

Wherein the request command is a printing control command, which may be TSPL, CPCL, ZPL or ESC standard command set. The ESC standard instruction set is suitable for common printers, the TSPL instruction set is suitable for label printers, and the CPCL standard instruction set is suitable for mobile printers. It should be noted that the request command is a mainstream standard command type of the printer, is different from a print control language freely developed by a device manufacturer, and has better universality so as to be conveniently identified by the server.
In this embodiment, the print control parameters include, but are not limited to, printer dpi, printer die width, print temperature, print coordinates, grayscale parameters, and the like.
On the basis of the foregoing embodiment, in a preferred embodiment, the parsing, based on a preset parsing service program, the request instruction to generate a standard instruction and return the standard instruction to the request device, so that the request device executes a corresponding operation according to the standard instruction specifically includes:
initializing according to the printing control parameters to generate a virtual canvas;

and sending the bitmap instruction to a request device, so that the request device prints according to the bitmap instruction.
In this embodiment, the server creates the virtual canvas by initializing according to the printing control parameters, specifically including setting the height, width, position, size, color, style, and the like of the virtual canvas according to the printing control parameters.
Then, the server analyzes the content of the request instruction, perfects the virtual canvas according to the content of the request instruction, and then converts the virtual canvas into a bitmap file to return to the request equipment.
On the basis of the above embodiment, in a preferred embodiment, the method further includes:
and generating an invariant request standard according to the server domain name to realize load balancing.
In this embodiment, the server is usually one or more computers, and a server domain name is used to replace an ip of the server, so that the computers can be flexibly configured according to the amount of requests, and the requesting device can use the servers without feeling when the server deployment changes, thereby realizing load balancing.
For example, when the ip of the server is 10.0.3.111, and the requesting device a performs instruction interaction with the server under the ip, the following problems may be faced during the use process: 1) for some reason, the ip changes, and the a client needs to change all the deployed applications; 2) the use amount of the client A is increased or clients such as BCD (binary coded decimal) and the like are added, so that the original server service needs to be upgraded, and the ip is changed; 3) the request amount has a large peak-valley difference according to the time period, resulting in resource waste of the server. In this case, the server domain name is used instead of the ip of the server, and even if the ip of the server changes, the influence on the requesting device is small in the instruction interaction process.
A second embodiment of the present invention provides an instruction interaction device based on server parsing, including:
a request instruction obtaining unit 201, configured to obtain a request instruction sent by a requesting device;
