Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a command calling method, system, device and readable medium. Background Art

[0002] Currently, software architectures are shifting from monolithic to microservices, and with the increasing number of servers, operations and maintenance are becoming increasingly complex. For example, stopping and starting services, automatically deploying and updating applications, and monitoring service status all require specific machines to perform corresponding functions. Some actions have dependencies, requiring a unified operations console for management. However, during actual command development and operation and maintenance invocation, some operations are tightly coupled with specific frameworks and are not designed and developed according to a command-based approach, making them difficult to reuse with other frameworks. Once a command is developed, how can it be distributed, deployed, and updated to the appropriate machines? How can this be achieved by masking differences in operating system programming, avoiding manual updates, achieving automatic updates, and remotely invoking commands be difficult? These are challenges facing existing technologies. Summary of the Invention

[0003] In view of this, the present invention proposes a command invocation method, system, device, and readable medium. The present invention proposes a command invocation method that manages the entire lifecycle of a command invocation through command development, command definition, command configuration, service-oriented command invocation, command deployment and update, command operation and maintenance monitoring, and command invocation code generation.

[0004] Based on the above purpose, one aspect of an embodiment of the present invention provides a command calling method, comprising the following steps: defining a command for calling a command in a command calling framework; establishing a connection between the publishing information of the command and the running node in the command calling framework according to the command definition to obtain the running node to which the command belongs; deploying or updating the running node according to the publishing information of the command and the node information of the running node; establishing a configuration for the command calling framework when calling the command, so as to enable the caller to call the command through the command calling framework.

[0005] In some embodiments, the command definition for calling a command in a command calling framework includes: setting two parameter receiving methods, namely, splicing command line strings and input streams, so that the command calling framework can receive input parameters of different lengths; establishing a command definition including a unique command identifier, execution program path, working directory, parameter receiving method, input parameter definition, output parameter definition, and whether it can be executed in parallel.

[0006] In some embodiments, establishing a connection between the release information of the command and the running node in the command calling framework according to the command definition to obtain the running node to which the command belongs includes: setting the download link of the command program to support the use of variables to apply to the download of the command program in different operating systems; establishing the release information of the command according to information including the operating system to which the command is applicable, the command program version, the command program download location, and the files that need to be deleted during the upgrade; and matching the command to the running node in the command calling framework through a command program deployment tool based on the release information of the command.

[0007] In some embodiments, the deployment or updating of the running node according to the release information of the command and the node information of the running node includes: managing the running node, obtaining the node information of the running node including the deployed commands, command versions, command installation locations and configurations; deploying or updating the running node according to the node information and the release information of the command, including downloading the command program, decompressing it to a specified directory, and deleting the file.

[0008] In some embodiments, the establishment of a configuration for the command calling framework to call the command so as to enable the caller to call the command through the command calling framework also includes: establishing a configuration including the authentication method, the caller's operating authority, whether to enable logging, and whether the command process is resident in memory when calling the command; providing statistics on the execution status of calling the command through log analysis of the command call, and feeding back the statistical results to the console.

[0009] In some embodiments, the configuration of establishing the command calling framework when calling the command to enable the caller to call the command through the command calling framework includes: the command calling framework encapsulates the call of the command as a remotely callable service, and provides a unified command calling entry. In response to the caller sending the command definition and corresponding parameters of the command through the command calling entry, the command calling framework matches the running node to which the command belongs to implement the call of the command.

[0010] In some embodiments, establishing the configuration of the command calling framework when calling the command to enable the caller to call the command through the command calling framework also includes: generating an agent that calls the command according to the command definition and corresponding parameters, and enabling the caller to call the command through the agent.

[0021] The following describes embodiments of the present invention. However, it is to be understood that the disclosed embodiments are merely examples and other embodiments can take various alternative forms.

[0022] In addition, it should be noted that all expressions using "first" and "second" in the embodiments of the present invention are intended to distinguish two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one. The terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusions, so that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but may also include elements not explicitly listed or inherent to such processes, methods, articles, or apparatuses.

[0023] One or more embodiments of the present application will be described below with reference to the accompanying drawings.

[0024] Based on the above objectives, a first aspect of an embodiment of the present invention provides an embodiment of a command calling method. Figure 1 FIG. 1 is a schematic diagram of an embodiment of a method for calling a command provided by the present invention. Figure 1 As shown, a command calling method according to an embodiment of the present invention includes the following steps:

[0025] S1. Define the command call in the command call framework;

[0026] S2. Establishing a connection between the command publishing information and the running node in the command calling framework according to the command definition to obtain the running node to which the command belongs;

[0027] S3. Deploy or update the running node according to the release information of the command and the node information of the running node;

[0028] S4. Establishing a configuration for the command calling framework to call the command, so that the caller can call the command through the command calling framework.

[0029] Figure 2 Shown is another schematic diagram of an embodiment of a command calling method provided by the present invention.

[0030] A method for command calling is provided, which establishes a command calling framework to manage command calling and defines a command, and uses metadata to describe the command, which has good scalability and mainly includes: a unique command identifier, an entry program path, a working directory, a parameter receiving method, an input parameter definition, an output parameter definition, whether parallel execution is possible, and other information. As shown in Table 1, the content of the command definition provided in the embodiment of the present invention is understood to include, but not limited to, only the command definition in Table 1 in actual applications. The metadata of the command definition can be further expanded as needed. The command definition is an abstract definition that does not strongly identify the operating system or programming language. Regarding the parameter receiving method, considering that the command calling has a limit on the length of the command line, when the input parameter is too large, it is not suitable for calling by splicing the command line. Two parameter input methods are provided in the embodiment of the present invention. When the input parameter is small, a direct string splicing method is used; when the input parameter is large, an input stream method is used. For the input stream method, a signal needs to be set. When the command program requires a parameter, a parameter input signal is issued. After the input signal is detected, the parameter is written to the input stream. As for whether it can be executed in parallel, because some commands can only be executed serially, if the called command is executed serially, when there are multiple command execution requests, they can only wait in queue.

[0032] Table 1

[0033] In an embodiment of the present invention, based on the command definition, a connection is established between the command's release information and the execution node in the command invocation framework, and the execution node to which the command belongs is found within the command invocation framework. The release information includes a command compressed package and a release information file. The command compressed package includes the application file and the command definition file, supporting compressed file types such as zip and tar. The release information file contains information such as the applicable operating system (Windows, Linux, Mac, etc.), the command program version, the program download location, and files to be deleted during upgrades. As shown in Table 2, the contents of the release information file provided in an embodiment of the present invention include, but are not limited to, the release information in Table 2 in actual applications. The release information content can be further expanded as needed. Command release primarily involves publishing new commands and new command versions. After a command developer completes development, they place the command program and release information into the command invocation framework, which automatically matches the command to the execution node within the framework. When releasing a new command version, in addition to updating the command program, some files may also be deleted. Command programs developed in different programming languages have different contents in different operating systems. For example, command programs developed in the Go language are completely different in Windows and Linux operating systems. Therefore, the command programs corresponding to each command need to be divided by operating system, but the release information file is the same. Therefore, the download link of the command program supports the use of variables. For example, the download link of the patch update command is: 127.0.0.1 / tool / @@OS@@ / patchcommand.zip, where @@OS@@ is a variable and the download tool will replace it according to the operating system of the running node.

[0034]

[0035] Table 2

[0036] Based on the command release information, the command's execution node can be found within the command invocation framework. Using the node information of the execution node, the command can be deployed or updated. Node information primarily includes: IP address, port number, deployed commands, command version, command installation location and configuration, public key, etc. This information allows the command, command version, and command installation directory installed on the execution node to be retrieved, enabling operations such as downloading the command program, extracting it to a designated directory, and deleting files. When updating a command, before overwriting a file, program usage issues arise. Therefore, the current command must first be stopped, the corresponding process ID of the executable program for the current command must be queried, and the process exited. The entire command update is automatically deployed and updated by the backend after receiving the command. Command deployment and updates are also standard commands, and corresponding operation logs will be generated.

[0037] Establish a command call framework to configure the command call during operation, including authentication methods, operation permissions, whether to enable logging, and whether the command process is resident in memory. Regarding authentication methods, private key signatures, public key verification, username and password, tokens, and other authentication methods are supported, and authentication methods can be expanded. Regarding operation permissions, the caller's permissions are controlled to prevent unauthorized users from executing commands. Support is provided for setting the logging range, and request and response parameters can be specified separately. Since some commands are frequently called, if a process is started for each call, performance and resource consumption issues will arise. Therefore, configuration is provided for whether to be resident in memory.

[0038] To analyze command calls and facilitate subsequent improvements and upgrades, we analyze backend logs to collect command execution status, including the number of failures and successes. For each command execution, if logging is enabled, you can view the command execution log using a generated unique representation, including input parameters, output parameters, success rate, exception stack trace, etc., and then feed the statistical results to the console.

[0039] The command itself can be executed through the command line. To facilitate the caller's call, the command call framework provides a unified command call entry, that is, the command call is encapsulated and then published as a remotely callable service. It supports publishing services in styles such as Socket, Rest, and Web Service.

[0040] Through the command definition and the corresponding parameters, a proxy for the command calling end can be generated. By default, proxy codes in multiple programming languages are supported. The caller can call the command through the proxy, making it convenient for the caller to call the command.

[0041] Based on the above purpose, the second aspect of an embodiment of the present invention proposes a command calling system, comprising the following modules: a first module 011, configured for defining a command for calling a command in a command calling framework; a second module 012, configured for establishing a connection between the publishing information of the command and the running node in the command calling framework according to the command definition, so as to obtain the running node to which the command belongs; a third module 013, configured for deploying or updating the running node according to the publishing information of the command and the node information of the running node; and a fourth module 014, configured for establishing a configuration when the command calling framework calls the command, so as to enable the caller to call the command through the command calling framework.
