However, if the other plug-in is a plug-in with pure function and no data storage, or a plug-in without data interaction, the communication, configuration, cooperation, calling, etc. operations between the plug-ins will fail. Moreover, the database is used as a plug-in mechanism of the transfer, and the data structure is required to be a very standardized plan, so that all plug-in developers can be familiar with and know the purposes of all links in the data structure.
According to the plug-in mechanism scheme which is commonly adopted, due to the fact that standardization of a data structure is very depended on, once the data structure changes, all plug-ins need to be modified in a linkage mode, and the plug-ins can only be communicated through a database, direct communication between the plug-ins cannot be achieved, and distributed communication and calling cannot be achieved.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Further, in the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Referring to fig. 1 and 2, the present invention provides a method for applying a software system extension plug-in a command word communication mode, comprising the following steps:
each function or each group of functions in the software system can be packaged into a command word, and a complete command word communication flow comprises a request input and a result output. The plug-in packages the own function into a command word, in the system or the calling communication of the cross system, the command word of the direct cmd plug-in can directly communicate and call the plug-in function in a cmd instruction mode, and the result data returned by the plug-in can be appointed to be in any format. The method can be applied to software systems in a self-hosting mode, a SaaS mode and a distributed mode.
S101, adding the command word into a corresponding software system, and adding a callback function corresponding to the command word.
Specifically, 1, adding a command word in a configuration file, such as a plg _ cmd _ default command word;
2. adding a command word callback function (function name custom name) in a configuration file for mapping functions of the command word, wherein one command word can map a plurality of functions, such as plg _ cmd _ default ═ a 'and plg _ cmd _ default ═ B';
3. function functions, each function representing a function point, are specific function execution codes, such as a and B functions, a function a adds 1 to the value of the C field of the database user table, a function B subtracts 1 from the value of the D field of the database user table, and when the plg _ cmd _ default command word is requested, the functions a and B are executed together, adding and subtracting the values of the two fields.
S102, initiating a command word request through a command word instruction, and forwarding the corresponding command word request to the corresponding extension plug-in.
Specifically, whether an extension plug-in exists or not is checked, if yes, the command word request is sent to the corresponding extension plug-in, and if not, prompt information is returned; other functions or other extension plug-ins in the software system initiate a request to the system through a call instruction, and the system can forward the command word to the corresponding plug-in according to the request; the request information includes command words, request plug-ins, request parameter(s), output format requirements, and may be applied to examples of the PHP programming language, but is not limited to the PHP programming language.
S103, after the command word request is received by the extension plug-in, judging whether the command word exists and judging whether the command word request meets the requirement.
Specifically, after receiving the command request, the system checks whether the command word exists in the system (the command word defined to the system in the command word development logic is checked whether the command word exists through a configuration file), if not, the system returns a prompt message, and if so, the system executes the corresponding command word request.
The extension plug-in receives a command word request distributed by the system, and firstly verifies whether the parameters of the request are correct and safe. The correctness is to verify whether the parameters are matched with the affiliated format, for example, whether the mailbox parameters are in a correct mailbox format, whether the mobile phone number parameters are in a correct number digit, whether the integer parameters are integers, whether the website parameters are websites, and the like; the legality is to verify whether the parameters contain dangerous intrusion and code content of injection, such as SQL injection code; and when the parameters are checked to have problems, returning prompt information, and if the parameters are not checked to have problems, executing the command word callback function.
The parameter verification standards of the command words are different due to different service scenes and service purposes, so the verification logic of parameter correctness and legality is defined by a developer, and the parameter rules of verification can be flexibly defined according to a technical framework and service logic; for example, a PHP Laravel framework is used as a command word bottom layer technical framework, parameter verification can follow Laravel form verification standards, and a Lavavel technical scheme can be directly adopted in the verification method and the verification process.
And S104, when the command word exists and meets the requirement, processing the command word request through the extended plug-in callback command word mapping function and outputting a request result.
Specifically, the extension plug-in analyzes the request parameter, calls back the mapping function of the extension plug-in, and executes a specific function. After the plug-in is expanded to process the result, the result is output no matter whether the result is finished or stopped; outputting the format of the output result according to the requirement during the request, and outputting a default format if the request is not required or the required format plug-in does not support; the output information comprises a state code, a state description and result data.
In the whole using process of the command word, the plug-in function is called directly through one command word without knowing what processing logic the other side is and analyzing the command through a database between the plug-in and the plug-in.
Advantageous effects
1. The network communication programming model is realized through the command words, the complexity of processing network data is reduced, the flexibility of a main program and a plug-in mechanism is improved, and the interaction between cross-business and cross-plug-ins is more convenient.
2. The single frame can support multiple plugins, simultaneously can subsequently support a multi-system multi-plugin mode, and can realize distributed calling among systems in a microservice mode.
3. The command words are flexible in communication and convenient to upgrade, when the service of the main program of the software or a database changes, plug-in linkage upgrade is not needed, and the software can be used compatibly even when running across programming languages or SaaS.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
