Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.
In the description of the embodiments of the present application, it is to be understood that, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a log output method according to an embodiment of the present application.
As shown in fig. 1, the method includes:
s101, obtaining a business statement, and executing the business statement in a first business environment.
Optionally, in the embodiment of the present application, a log output method may be applied to a plurality of assembly languages, including but not limited to JavaScript, Java, C + +, and Python languages. Based on the above language, a software system meeting different requirements can be designed, the software system can be composed of program codes, and different codes can be composed of business statements handling different businesses, where a business can refer to a certain function or a certain event, for example, in the field of network online education, a certain business can be a student entering a virtual classroom to practice learning of a certain subject, so each business statement can include one or more groups of program codes and also include one or more character strings.
Optionally, a plurality of business statements may be included in a software system, and a business environment for the business statement is required for implementation or execution of the business statement, where the business environment may be a virtual concept and may be formed by execution of program code and/or invocation of a function, for example, the business environment may be a queue in a JavaScript language, or the business environment may be a thread in a Java language. The business language may be run or executed in a business environment to implement data processing or business processing.
Optionally, the execution main body of the embodiment of the present application may be a processor, and the processor first establishes a first service environment as an environment for processing a service statement. When the processor needs to process a certain data or implement a certain service, the processor acquires the data or a service statement corresponding to the service, the service statement may be stored in the register in advance, and after acquiring the service statement, the processor executes the service statement in the first service environment, that is, runs the program code included in the service statement in the first service environment.
S102, triggering a log output statement, establishing a second service environment, and packaging an evaluation code aiming at the service statement into the second service environment; the evaluation code is used to evaluate the business statement and log the output.
It can be understood that when the service statement is executed in the first service environment, sometimes the parameter of the execution process of the service statement needs to be recorded or evaluated, and then the parameter is output to a designated position or printed out in the form of a log, on one hand, the log can reflect the operation condition of the service statement, so that the subsequent debugging or debugging of the whole software system is facilitated, and the safety of the software system is improved; on the other hand, the log can be used for data production, so that calling and using of other business statements of the software system are facilitated, and therefore log output plays an important role in the software system.
Optionally, there may be a corresponding log statement for the output of the log, and the log statement includes a program code for logging the service statement. The program code included in the log statement can be set in the program code included in a certain service statement according to the service logic, so that the service statement, the log statement and the service statement can be output in a log mode through the log statement when the service statement, the log statement and the service statement are sequentially executed according to the execution logic in the process of executing the service statement.
In the related art, when a log statement is executed according to logic, the log statement acquires a service parameter corresponding to the service statement and evaluates the service parameter, but if an error occurs in the evaluation process, for example, the service parameter is erroneous or the evaluation process is crashed, the log statement is executed in a stuck state, so that subsequent service statements cannot be continuously executed, and if the error is more serious, the whole system software is crashed or a security hole is formed.
Optionally, in this embodiment of the present application, when the log statement is logically executed, a log output statement in the log statement is triggered, and the log output statement may include one or more sets of program codes, so that the log output statement may include an environment building program code, and after the log output statement is triggered, the environment building program code is immediately executed to build a second service environment different from the current first service environment. Because the log output process needs to use the correlation function to evaluate the service parameters corresponding to the service statements, the log output statements also include evaluation codes, and the evaluation codes are used for evaluating the service statements and outputting logs.
Optionally, since log output for the service statement is not necessary for service statement operation, the evaluation code may be encapsulated in the second service environment by calling a related function, and when the whole software system is in an idle state, the evaluation code is executed to realize log output corresponding to the service statement, so that the processing task amount of the processor at different times may be balanced, the processing speed of the processor for the service statement may be increased, and the stability of the software system may be improved.
S103, returning to the first business environment, and continuing to execute the business statement in the first business environment.
Optionally, since the evaluation processing of the service statement and the log output are both performed in the second service environment, and the second service environment and the first service environment are different service environments, that is, the execution of the service statement and the parameter evaluation of the log statement and the log output are isolated to different service environments for execution, when the parameter evaluation and the log output are performed in the second service environment, even if a parameter evaluation and log output error occurs in the second service environment, the execution of the service statement in the first service environment is not affected, and the stability of the whole software system is effectively improved.
In the embodiment of the application, firstly, a business statement is obtained, and the business statement is executed in a first business environment; then triggering a log output statement, establishing a second service environment, and packaging an evaluation code aiming at the service statement into the second service environment; the evaluation code is used for evaluating the business statement and outputting a log; and finally returning to the first business environment, and continuing to execute the business statement in the first business environment. When the service statement is executed in the first service environment and the log related to the service statement needs to be output, a second service environment can be established, and the log output of the service statement is executed in the second service environment.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a log output method according to another embodiment of the present application.
As shown in fig. 2, the method steps include:
s201, obtaining a business statement, and executing the business statement in a first business environment.
For a detailed description of the step S201, reference may be made to the description of the step S101, which is not described herein again.
S202, triggering a log output statement, and establishing at least one asynchronous queue as a second service environment; the second service environment is different from the first service environment, and the operation priority of the second service environment is smaller than that of the first service environment.
Optionally, there may be a corresponding log statement for the output of the log, and the log statement includes a program code for logging the service statement. The program code included in the log statement can be set in the program code included in a certain service statement according to the service logic, so that the service statement, the log statement and the service statement can be output in a log mode through the log statement when the service statement, the log statement and the service statement are sequentially executed according to the execution logic in the process of executing the service statement.
For describing the log output process in more detail, the following description is given by taking the example in the JavaScript language. In the JavaScript language, the first service environment in which each service statement operates is a queue, that is, one queue includes service statements that implement each service or data processing, and each service statement operates in sequence in one queue. When the log statement is executed according to logic, the log output statement in the log statement is triggered, the log output statement can comprise one or more groups of program codes, so that the log output statement can comprise environment establishing program codes, and after the log output statement is triggered, the environment establishing program codes can establish at least one asynchronous queue different from the first service environment and use the asynchronous queue as a second service environment. The asynchronous queue and the queue in the first service environment may be two different queues, and the processor may execute the service statements in each queue asynchronously, so that the queue in the first service environment is different from the queue in the second service environment, and the second service environment is different from the first service environment.
Optionally, after the processor executes the environment establishment program, an asynchronous queue different from the first service environment, that is, a second service environment, may be established, and the processor may execute the statements in the queues asynchronously, where the execution of the service statements in the first service environment is an important link in the operation process of the entire software system, and therefore the service statements in the first service environment need to be executed preferentially, and the processor processes the log statements in the second service environment when the processor is idle. Therefore, after the processor establishes the second service environment, the operation priority of the second service environment is set to be low, the operation priority of the first service environment is set to be high, and the operation priority of the second service environment is smaller than the operation priority of the first service environment, so that after the processor establishes the second service environment, the service statements in the first service environment can be preferentially executed according to the operation priorities of different service environments, thereby avoiding the real-time operation of the log statements in the second service environment, and if the parameter evaluation error or the log output error occurs in the operation log statements, the service statements in the first service environment cannot be executed, further influencing the operation of the whole software system, and further improving the stability of the software system.
S203, acquiring the service type corresponding to the service statement, and acquiring an evaluation code corresponding to the service type.
Optionally, the service types, the service parameters, the evaluation manners, and the log output types corresponding to different service statements in the first service environment may be different, so as to output different logs, and therefore when the service statements in the first service environment need to be evaluated, the service types corresponding to the service statements need to be obtained first.
And S204, calling an anonymous function to package the evaluation code into a second service environment.
Optionally, multiple types of anonymous functions with different functions may be included in the JavaScript language, and the anonymous functions may be composed of program codes or character strings for implementing different functions. The processor calls an anonymous function corresponding to a preset log statement, and encapsulates the obtained evaluation code through the anonymous function, wherein the encapsulation means that the obtained evaluation code is subjected to memorability to hide the attribute and implementation details of an object, only an interface is exposed to the outside, the access level of reading and modifying of the attribute in a program is controlled, the evaluation code is not immediately executed, and only the anonymous function is required to execute evaluation on the evaluation code next time.
S205, returning to the first business environment, and continuing to execute the business statement in the first business environment.
Optionally, since the evaluation processing of the service statement and the log output are both performed in the second service environment, and the second service environment and the first service environment are different service environments, that is, the execution of the service statement and the parameter evaluation of the log statement and the log output are isolated to different service environments for execution, when the parameter evaluation and the log output are performed in the second service environment, even if a parameter evaluation and log output error occurs in the second service environment, the execution of the service statement in the first service environment is not affected, and the stability of the whole software system is effectively improved.
S206, triggering the parameter evaluation statement and acquiring the service parameter corresponding to the service statement.
Optionally, the log statement may further include a parameter evaluation statement, where triggering of the parameter evaluation statement may be triggered after the processor executes the service statement in the first service environment, and at this time, the processor acquires the service statement that needs to be logged and the service parameter corresponding to the service statement, for example, in the field of network online education, if a service executed by a certain service statement may be a service that a student object is named as student entering a room, a value needs to be taken for the service statement to acquire the service parameter corresponding to the service statement, and the service parameter corresponding to the service statement may be student name.
S207, calling an anonymous function in the second service environment to execute an evaluation code to evaluate the service parameter, and obtaining an evaluation result.
Optionally, after the service parameter corresponding to the service statement is acquired, the anonymous function may be called in the second service environment to execute the evaluation code encapsulated by the anonymous function, and execute the evaluation code, and after the evaluation code is run, evaluation processing may be performed according to the service parameter corresponding to the acquired service statement. For example, in the field of online network education, a service executed by a service statement may be that a student object is named student's name entering a room, a service parameter corresponding to the service statement may be student's name, an evaluation code may be log (═ student ' + student's name + ') entering the room, and after the evaluation code is processed, an evaluation result is finally obtained that "student $ { student's name } enters the room", that is, a log corresponding to the service statement is "student $ { student's name } entering the room", and the log may be output and/or printed.
And S208, saving the evaluation result.
Optionally, in order to facilitate later debugging or troubleshooting of errors, the evaluation result, that is, the output log, may also be stored in a designated local location or in a server.
In the embodiment of the application, a log output statement is triggered, and an asynchronous queue is established as a second service environment; the second service environment is different from the first service environment, and the operation priority of the second service environment is smaller than that of the first service environment. When the business statement is executed in the first business environment and the log related to the business statement needs to be output, a second business environment can be established, and the log output of the business statement is executed in the second business environment.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a log output method according to another embodiment of the present application.
As shown in fig. 3, the method steps include:
s301, obtaining a business statement, and executing the business statement in the first business environment.
For the detailed description of the step S301, reference may be made to the description of the step S101, which is not described herein again.
S302, triggering a log output statement, and establishing at least one log thread as a second service environment; wherein the second service environment is different from the first service environment.
Optionally, there may be a corresponding log statement for the output of the log, and the log statement includes a program code for logging the service statement. The program code included in the log statement can be set in the program code included in a certain service statement according to the service logic, so that the service statement can be log-output through the log statement when the service statement, the log statement and the service statement are sequentially executed according to the execution logic in the process of executing the service statement.
To describe the log output process in more detail, the following description is given by way of example in the Java language. In the Java language, the first service environment in which each service statement runs is a thread, that is, a thread may include at least one service statement that implements service or data processing, and the processor may process multiple threads simultaneously or sequentially process service statements in threads. When the log statement is executed according to the logic, a log output statement in the log statement is triggered, and the log output statement may include one or more groups of program codes, so that the log output statement may include an environment establishing program code, and after the log output statement is triggered, the environment establishing program code may establish at least one thread different from the first service environment, and use the established thread as a second service environment. The established threads can be two threads different from the threads in the first service environment, and the processor can asynchronously execute the program codes in the different threads, so that the second service environment is different from the first service environment due to the difference between the threads in the first service environment and the established threads in the second service environment.
Optionally, the second service environment may include multiple log threads, that is, each time there is a service statement that requires to output a log, one thread may be established as a log thread for implementing log output of the service statement, and all the established log threads share one memory, so that all the log threads are placed in the second service environment.
S303, packaging the evaluation code aiming at the service statement into a second service environment; the evaluation code is used to evaluate the business statement and log the output.
Optionally, multiple types of anonymous functions with different functions may be included in the Java language, and the anonymous functions may be composed of program codes or character strings for implementing different functions. Therefore, each log thread in the at least one log thread can correspond to an anonymous function, the processor calls the anonymous function corresponding to a preset log statement, the evaluation code is packaged into different log threads through the anonymous function, the packaging means that the acquired evaluation code is subjected to memorability and hiding the attribute and implementation details of an object, only an interface is exposed to the outside, the access level of reading and modifying of the attribute in the program is controlled, the evaluation code cannot be executed immediately, and only the anonymous function is subjected to execution evaluation on the evaluation code next time.
S304, returning to the first business environment, and continuing to execute the business statement in the first business environment.
Optionally, since the evaluation processing of the service statement and the log output are both performed in the second service environment, and the second service environment and the first service environment are different service environments, that is, the execution of the service statement and the parameter evaluation of the log statement and the log output are isolated to different service environments for execution, when the parameter evaluation and the log output are performed in the second service environment, even if a parameter evaluation and log output error occurs in the second service environment, the execution of the service statement in the first service environment is not affected, and the stability of the whole software system is effectively improved.
S305, triggering the parameter evaluation statement, acquiring the service parameters corresponding to the service statements, and performing priority ordering on the service parameters according to a preset rule.
Optionally, the log statements may further include parameter evaluation statements, where triggering of the parameter evaluation statements may be triggered after the processor executes the service statements in the first service environment, at this time, the processor obtains the service statements corresponding to the log threads in the second service environment and the service parameters corresponding to the service statements, at this time, priority ordering may be performed on the service parameters according to a preset rule, for example, in the field of online education over a network, the preset rule may be set according to the service types corresponding to the service parameters, the service types may be that a student enters a room, selects a subject, gives lessons, feeds back after lessons, and the like, the importance degrees of different service types are different, if a log corresponding to the feedback after lessons needs to be preferentially obtained at a certain time, the corresponding service parameters fed back after lessons may be set to have a high priority in the preset rule, all traffic parameters in the second traffic environment can be prioritized by a preset rule.
S306, acquiring the utilization rate of the processor, and if the utilization rate of the processor is smaller than a utilization rate threshold, acquiring the service parameter with high priority.
Alternatively, the utilization rate of the processor represents how busy the processor executes threads, and if too many threads are processed by the processor at the same time, the thread execution error of the processor may be caused, and the whole software system may be crashed. Therefore, the utilization rate of the processor can also be obtained, if the utilization rate of the processor is smaller than the utilization rate threshold value, the processor is in an idle state at the moment, and the log thread can be executed at the moment to realize the output of the log. The processor obtains the result of the priority ordering of all the service parameters and obtains the service parameters with high priority.
S307, an anonymous function corresponding to the service parameter with high priority is obtained, the anonymous function is called to execute an evaluation code to evaluate the service parameter, and an evaluation result is obtained.
Optionally, each log thread may correspond to an anonymous function, so that an anonymous function corresponding to a service parameter with a high priority may be obtained first to execute an evaluation code encapsulated by the anonymous function, and execute the evaluation code, and after the evaluation code runs, evaluation processing may be performed according to the service parameter with the high priority, and an evaluation result may be obtained.
And S308, saving the evaluation result.
Optionally, in order to facilitate later debugging or troubleshooting of errors, the evaluation result, that is, the output log, may also be stored in a designated local location or in a server.
