Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Referring to fig. 1, an embodiment of the present invention provides a method for invoking a virtual machine management tool, which includes the following steps 101 to 105, which are described in detail below.
Step 101: receiving data sent by a requester, wherein the data comprises a first part of data and a second part of data, the first part of data comprises an action identifier, and the second part of data comprises a requirement parameter and an index value corresponding to the requirement parameter.
The requesting party is specifically a third-party application program. The virtual machine management tool is specifically microsoft virtual machine deployment and management tool SCVMM.
The data sent by the third-party application (i.e., the requester) to the virtual machine management tool normally includes at least two parts of data, i.e., a first part of data and a second part of data.
The first part of data at least comprises an action identifier, and more specifically, the first part of data comprises an action function and an action identifier corresponding to the action function. The action function is a field action named by self definition, and the action identifier is a value corresponding to the action. For example, the first portion of data is: action search _ sc _ jobA.
The second part of data comprises a demand parameter and an index value corresponding to the demand parameter. Wherein the requirement parameter is one parameter in a parameter set args. For example, the second portion of data is: guid 21fqwe-12313-dfds-s12 efe.
In the embodiment of the present invention, the step 101 includes:
and receiving the data sent by the requester through a specified API data interface.
The API data interface is, for example, an entry written in python, which receives API data interaction, and defines an API format therein, allowing receiving some data transmitted by a third-party application.
It should be noted that, under an abnormal condition, the data sent by the third-party application program to the virtual machine management tool may not include the action function, that is, the virtual machine management tool may not detect the action function in the received data, at this time, a subsequent calling process is not performed, but a friendly prompt message is returned to the third-party application program to prompt that the sent data is incorrect.
Step 102: and determining a command set corresponding to the action identifier.
In the embodiment of the present invention, the command set is an scvmm powershell command set, and the format is, for example:
the action function is as follows: action identification, command: command corresponding value, parameter set: a demand parameter; namely, it is
action：[xx]，cmd：[yy]，args：[zz]。
Specifically, in order to determine the command set corresponding to the action identifier, a plurality of scvmmm powershell command sets need to be preset to select a matching command set.
For example, the scvmmm powershell command sets are:
thus, when the first part of data received in step 101 is action, search _ sc _ job, i.e. the action id is search _ sc _ job, step 102 determines that the corresponding command set is: ' action ' search _ sc _ jobb ', ' cmd ': sc-jobb ', ' args ': guid '.
Step 103: and if the demand parameters in the command set are consistent with the demand parameters in the second part of data, generating execution parameters according to the command set and the second part of data.
In the embodiment of the invention, the execution parameter is a character string and is formed by splicing a value corresponding to the command in the command set, a demand parameter and an index value corresponding to the demand parameter.
Wherein, the splicing mode is for example: [ cmd ] - [ args ] [ args-value ].
Specifically, referring to fig. 2, the step of generating the execution parameter according to the command set and the second partial data includes:
step 201: determining a value corresponding to a command from the command set;
step 202: determining an index value corresponding to the demand parameter from the second part of data;
step 203: and generating the execution parameters according to the value corresponding to the command, the demand parameters and the index values corresponding to the demand parameters.
In the embodiment of the present invention, if the demand parameters in the command set are not consistent with the demand parameters in the second part of data, an error message needs to be returned to the requester, i.e., the third-party application.
Step 104: and sending the execution parameters to a task scheduler of the virtual machine management tool, and receiving an execution result returned by the task scheduler.
Specifically, after the execution parameter is generated in step 103, the execution parameter may be sent to the scvmm task scheduler to call the powershell command console, execute the execution parameter, and wait for receiving the execution result returned by the scvmm task scheduler.
Step 105: and returning the execution result to the requester.
Therefore, the calling of partial functions of the virtual machine management tool, particularly scvmm, is realized, the efficiency of the existing virtual machine management work is improved, and the increasing operation and maintenance requirements of the virtual machine are met.
The present invention is described in detail below with reference to a specific application scenario.
Firstly, a third-party application program A accesses an API data interface of the scvmm system and sends two pieces of data, which are respectively:
action:search_sc_job；
guid:21fqwe-12313-dfds-s12efe。
secondly, the scvmm system selects a command set corresponding to the "search _ sc _ jobs" from a plurality of preset command sets according to the action identifier "search _ sc _ jobs" corresponding to the action, specifically:
‘action’:‘search_sc_job’,‘cmd’:‘sc-job’,‘args’:‘guid’；
taking out a requirement parameter guid in the args, and searching an index value of the guid in the data to obtain:
guid:21fqwe-12313-dfds-s12efe；
performing character splicing on cmd and args according to a splicing mode [ cmd ] - [ args ] [ args-value ], and obtaining a character string: sc-job-guid 21fqwe-12313-dfds-s12 efe.
And finally, transmitting the character string to a powershell command desk for execution to obtain a return result B, and returning the return result B to the third-party application program A.
