Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, a script extension method is provided, and this embodiment is illustrated by applying the method to a terminal, and it is understood that the terminal may be a mobile terminal, a computer, or a special-purpose device. Among them, the mobile terminal is, for example, a mobile phone, a tablet computer, a handheld POS (point of sale) machine. Computers such as desktop computers, notebook computers, and the like. A special device with Modem function, such as a Modem (english name Modem), commonly called "cat", etc. The script extension method specifically comprises the following steps:
step 102, loading an extended script; an extended script is a pre-written script that is used to implement a customized function.
Specifically, the user writes the extension script in advance according to the customized function that needs to be implemented. And the terminal loads the extended script.
In one embodiment, the user pre-writes extension scripts and uploads them to a pre-set server according to the customized functionality that the user needs to implement. The terminal may download the extended script at a preset server.
And step 104, interpreting the extended script into a task execution command which can be identified by the task execution engine through the script interpreter.
The script interpreter is an interpreter for translating the extended script into a task execution command which can be recognized by the task execution engine. The executive task engine is an engine for executing task commands. The execution task command has the same function as the extended script and can be executed only by the execution task engine.
Specifically, the terminal interprets the loaded extended script through the script interpreter to interpret the extended script into a task execution command recognizable by the task execution engine.
In one embodiment, the execute task command may be an "at (attention)" command.
In one embodiment, the executive task engine may be an "AT" engine.
It is understood that the interpreted task execution command for an extended script may be one or more. A plurality is at least two.
It can be understood that the extended script is directly interpreted into the execution task command which can be recognized by the execution task engine, and because the functional flow for executing the task command is known, if a problem occurs in the process of executing the task command, the execution task command with the problem can be directly and quickly positioned according to the functional flow, so that the execution task command with the problem can be quickly corrected, and the efficiency of generating an execution result is improved.
And step 106, sending the task execution command to the task execution engine through the virtual channel.
The virtual channel is a logic channel for realizing input and output of the executive task engine.
It can be understood that the script interpreter on the terminal inputs the interpreted task execution command to the task execution engine through the virtual channel, and the task execution engine can output the execution result to the rule engine through the virtual channel. Thus, the input and output of the executive task engine is implemented by the virtual channel.
The execution result is a result generated after the executive task engine executes the executive task command. The rule engine is an engine that executes a corresponding script according to a preset rule. The rule engine is used for supporting the execution of a task execution command, and can also be used for supporting a user to define a simple data processing flow due to the functions of condition judgment, character comparison and the like supported by the self-contained script language.
And step 108, executing the task execution command through the task execution engine, generating an execution result and returning the execution result to the virtual channel.
Specifically, the executive task engine on the terminal receives an executive task command sent by the script interpreter through the virtual channel. The executive task engine can execute the executive task command and generate an execution result. Further, the executive task engine on the terminal returns the generated execution result to the virtual channel.
It can be understood that, when there are a plurality of executed task commands interpreted by one extended script, the executed task engine may generate a final executed result after all the executed task commands are executed.
And step 110, returning the execution result to the rule engine through the virtual channel so as to interact with the outside.
Specifically, the rule engine on the terminal receives the execution result through the virtual channel. Further, the rule engine on the terminal sends the execution result to the outside to interact with the outside.
The script extension method, the script extension device, the computer equipment and the storage medium are used for loading the extension script, interpreting the extension script into a task execution command which can be identified by the task execution engine through the script interpreter, and sending the task execution command to the task execution engine through the virtual channel to complete execution. The execution of the task execution command can be completed and the execution result can be generated through the task execution engine without additional hardware cost. And finally, returning the generated execution result to the rule engine through the virtual channel so as to interact with the outside. The generated execution result can be transmitted to the outside for interaction without additionally increasing a hardware unit for controlling the terminal to interact with the outside. In the whole process, no extra cost expense of hardware is involved, so that the script extension method can save the cost of the hardware.
In one embodiment, the method further comprises: executing the startup script through the rule engine; after the startup script is executed, detecting whether an extended script to be executed exists through a rule engine; and when detecting that the extended script to be executed exists, executing the step of loading the extended script and the subsequent steps until an execution result is returned to the rule engine through the virtual channel so as to realize the execution of the extended script.
The startup script is a script which can be executed to start up the terminal.
Specifically, a rules engine on the terminal executes the boot script. And after executing the startup script, the rule engine on the terminal further detects whether an extended script to be executed exists. When the rule engine on the terminal detects that there is an extended script to be executed, the extended script can be executed. It can be understood that the steps 102 to 110 are specific steps for executing each extended script, and therefore, the step of loading the extended script and the subsequent steps can be executed until the execution result is returned to the rule engine through the virtual channel, so as to implement the execution of the extended script.
In one embodiment, the boot script is executed only when the terminal is powered on to complete configuration of the initial state of the external device on the terminal. For example, the rule engine on the terminal executes the startup script to complete the setting of the high and low levels of the GPIO and the initialization of the plug-in device when the terminal is powered on, and may also complete the setting of the configuration items, such as setting a preset time interval corresponding to the timing task.
In one embodiment, when the existence of the extended script to be executed is detected, the extended script can be executed regularly. It is understood that there may be one or more extended scripts to be executed, and when there are multiple extended scripts to be executed, each extended script may be executed in sequence at regular time.
In the embodiment, whether the extended script to be executed exists or not is detected by the rule engine on the terminal, and the step of loading the extended script and the subsequent steps are executed after the extended script to be executed exists, so that the useless steps executed by the terminal when the extended script to be executed does not exist can be avoided, and the energy consumption of the terminal is saved.
In one embodiment, the method further comprises: and if the number of the extended scripts to be executed is multiple, after the current extended script is executed and a preset time interval is reached, taking the next extended script as the current extended script, and returning to the step of executing the loaded extended script and the subsequent steps so as to execute the next extended script.
Specifically, if there are a plurality of extension scripts to be executed, the rule engine on the terminal takes the next extension script as the current extension script after the current extension script is executed and when a preset time interval is reached, and returns to the step of executing the extension script and the subsequent steps to execute the next extension script. Namely, the steps 102 to 110 can be executed for each extended script to implement the execution of the extended script, and after one extended script is executed, the next extended script is executed in a timed manner, that is, the steps 102 to 110 are continuously executed for the next extended script to implement the execution of the next extended script.
In this embodiment, after the current extension script is executed and a preset time interval is reached, the rule engine on the terminal takes the next extension script as the current extension script, and returns to the step of executing the loading extension script and the subsequent steps to execute the next extension script. Therefore, the rule engine on the terminal can orderly execute all the extension scripts to be executed in order, and the execution of the extension scripts to be executed is not influenced mutually.
In one embodiment, the method further comprises: and when detecting that the extended script to be executed does not exist, executing the dormant script through the rule engine to enter a dormant state.
The sleep script is a script for making the terminal enter a sleep state after being executed.
Specifically, when the rule engine on the terminal detects that no extension script to be executed exists, the sleep script is executed. And after the rule engine on the terminal executes the sleep script, the terminal enters a sleep state.
In this embodiment, when the rule engine on the terminal detects that there is no extension script to be executed, the terminal enters a sleep state by executing the sleep script, so that energy consumption of the terminal can be saved.
In one embodiment, the method further comprises: after entering a dormant state, continuously detecting whether an extended script to be executed exists through a rule engine; and when detecting that the extended script to be executed exists, executing the awakening script, and returning to the step of executing the loading extended script after awakening.
The wake-up script is a state that can restore the terminal in the dormant state to the state before entering the dormant state after being executed.
Specifically, after the terminal enters the sleep state, the rule engine continues to detect whether the extended script to be executed exists. And when the rule engine on the terminal detects that the extended script to be executed exists, executing the wake-up script. And after the rule engine on the terminal wakes up the terminal, returning to the step of loading the extended script and the subsequent steps.
In this embodiment, when the rule engine on the terminal detects that there is an extended script to be executed, the wakeup script is executed, so that the terminal can be quickly restored from a sleep state that saves energy consumption to a state before sleep, so as to execute the step of loading the extended script and subsequent steps.
In one embodiment, after sending the execute task command to the execute task engine via the virtual channel, the method further comprises: if the field for executing the task command is the field which can be identified by the task execution engine, executing the step of executing the task execution command by the task execution engine; and when the field of the task execution command contains a field which cannot be identified by the task execution engine, informing the script interpreter of re-analyzing the extended script through the virtual channel.
Specifically, if the fields for executing the task command are all identifiable fields, the task execution engine on the terminal executes the task execution command, generates an execution result and returns the execution result to the virtual channel; and returning the execution result to the rule engine through the virtual channel so as to interact with the outside. And if the field for executing the task command has the field which can not be identified, the task executing engine on the terminal informs the script interpreter to re-analyze the extended script through the virtual channel.
In one embodiment, after receiving the notification, the script interpreter may re-interpret only the execute task command having unrecognized fields, or may re-parse the entire loaded extended script.
In this embodiment, if there is a task execution command of an unrecognizable field, the virtual channel notifies the script interpreter to re-analyze the extended script, so that the task execution engine can be ensured to smoothly complete execution of the task execution command.
In one embodiment, the number of the task execution commands obtained by interpreting the extended script is multiple; executing the execute task command by the execute task engine, and generating an execution result comprises: in the process of executing a plurality of task execution commands through the task execution engine, redirecting the output of a previous target task execution command into the input of a next task execution command until a plurality of task execution commands are executed, and generating an execution result; the prior target execution task command is an execution task command which is executed in advance and needs to make output as redirection input.
Wherein, the redirection (Redirect) is to relocate the execution result of the previously executed task command as the input of the subsequently executed task command.
It is understood that, for example, the next task execution command is to add two factors, and the first output result and the second output result generated after the previous target task execution command is executed can be redirected to the first input factor and the second input factor of the next task execution command by redirection, so as to execute the next task execution command, that is, to complete the addition of the two factors.
Specifically, in the process of executing a plurality of task execution commands through the task execution engine, the task execution engine on the terminal takes the output of the previous target task execution command as the input of the next task execution command corresponding to redirection until the plurality of task execution commands are executed, and generates an execution result.
In this embodiment, by redirecting the output of the previous target execution task command to the input of the next execution task command, the execution task engine can complete the execution of the execution task command according to the specified direction to generate the execution result.
In one embodiment, the terminal loads the extended script, as illustrated in the flowchart of the script extension step of FIG. 2. And the script interpreter on the terminal interprets the extended script into a task execution command which can be identified by the task execution engine through the virtual channel and sends the task execution command to the task execution engine. And if the field for executing the task command has the field which can not be identified, the task executing engine on the terminal informs the script interpreter to re-analyze the extended script through the virtual channel. And if the fields for executing the task command are all identifiable fields, executing the task executing command by a task executing engine on the terminal. And the execution of the execution task engine on the terminal returns the execution result generated according to the execution task command to the rule engine through the virtual channel. And the rule engine on the terminal sends the execution result to the outside so as to interact with the outside.
In one embodiment, the terminal is powered on (i.e., "module powered on") and the rule engine executes the boot script, as shown in the flowchart of the script extension step of fig. 3. And after executing the startup script, the rule engine on the terminal further detects whether an extended script to be executed exists. If a plurality of extension scripts are to be executed, the rule engine on the terminal takes the next extension script as the current extension script after the current extension script is executed and when a preset time interval is reached, and returns to the step of executing the loading extension script and the subsequent steps so as to execute the next extension script. And when the rule engine on the terminal detects that the extension script to be executed does not exist, executing the sleep script. And after the rule engine on the terminal executes the sleep script, the terminal enters a sleep state. And after the terminal enters a dormant state, continuously detecting whether the extended script to be executed exists through the rule engine. And when the rule engine on the terminal detects that the extended script to be executed exists, executing the wake-up script. And after the rule engine on the terminal wakes up the terminal, returning to the step of executing the loading of the extended script. And when the rule engine on the terminal does not detect the existence of the extended script to be executed after exceeding the time length threshold value, interrupting the awakening.
