[0002] With the development of technologies such as big data, cloud computing, and artificial intelligence, the impact of computer technology on human life has gradually increased, and the demand for talents in the computer field has also increased. The training of computer technology talents should combine theoretical teaching, dynamic practice, and practical training tests. Traditional tests are either theoretical tests on paper or experimental reports using operation screenshots. This not only increases the workload of teachers, but also does not provide real-time feedback, resulting in poor test results.

The resource cataloging process is relatively complicated, and the debugging process is not flexible enough; 3. OpenStack does not support sending instructions directly to virtual machines for execution verification, and needs to be performed through virtual machines on the same network segment or other third-party plug-ins, resulting in poor stability.

[0024] The management backend determines the test score of the user according to the correct answer results and the wrong answer results in all containers.

[0025] Optionally, the management backend determines whether the reply result in the container is correct based on the script execution result returned by the container, including:

[0026] If the verification script running in the container is a non-error script, the management backend determines that the response result in the container is correct when there is no error information in the script execution result returned by the container; or

[0027] If the verification script running in the container is a comparison value script, the management backend determines whether the value in the script execution result returned by the container is the same as the expected value, and if so, determines that the response result in the container is correct.

[0028] Optionally, the platform further includes a security module, and the method further includes:

[0029] The security module obtains the identity information of the user in response to receiving the practical training test request sent by the user terminal;

[0047] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] As mentioned in the background technology, in view of the problems in the prior art, this application proposes a remote training test method. The remote training test method provided in the embodiment of this application can be applied to a remote training test platform, which includes a management background, a user end, a container module and a database.

[0050] Figure 1 Flowchart of a remote training test method provided by the embodiment of the present application. Figure 1 , the remote training test method specifically includes:

[0051] S110, in response to detecting a practical training test request from the user end, the management backend determines all test questions corresponding to the current test based on the database, sends all test questions to the user end for display, and generates a container scheduling instruction and sends it to the container module.

[0052] In an embodiment of the present application, the remote training and testing platform can adopt a BS (Browser / Server Architecture) access architecture, and users can use the remote training and testing service through a user terminal deployed on a terminal without installing a plug-in.

[0053] The user end may be a Web. The user can perform operations on the page displayed on the user end, and the page converts the operations into practical training test requests, which are transmitted to the management backend through an API (Application Programming Interface).

[0054] Specifically, the management backend can be used to handle various operations of the remote training and testing platform. In order to meet the needs of rapid response, persistent storage, etc. within the platform, the management backend can communicate with other modules such as container modules and databases to ensure reliable and efficient operation of the platform.

[0055] Figure 2 is a schematic diagram of a remote training and testing platform provided in an embodiment of the present application, such as Figure 2 As shown, the management backend can communicate with the security module, cache module, database, object storage module and container module.

[0056] In the embodiment of the present application, in order to further ensure the security of the remote training and testing platform, a security module can also be set in the remote training and testing platform, such as Figure 2 The user end can send a training test request to the security module, which will then verify and forward it to the management platform.

[0057] In one example, the remote training test platform provided in the embodiment of the present application further includes a security module, and the remote training test method provided in the embodiment of the present application further includes:

[0058] The security module obtains the user's identity information in response to receiving the practical training test request sent by the user end; the security module authenticates the user based on the user's identity information. If the identity authentication passes, the security module performs authority verification on the user based on the user's identity information. If the authority verification passes, the practical training test request is forwarded to the management background.

[0059] Specifically, after receiving the practical training test request sent by the user end, the security module may first obtain the user's identity information, for example, the identity information may be the user's login code. Further, the security module may authenticate the identity information to determine whether the identity information is incorrect, so as to prevent other users from using the remote practical training test service with tampered identity information. If the identity authentication is passed, the identity information may be further authenticated, such as determining whether the identity information has the authority to conduct the test, or determining whether the identity information has the authority to conduct the current test requested.

[0060] Furthermore, if both identity verification and authority verification are passed, the security module can send the practical training test request to the management backend.

[0061] Through the above example, security verification is achieved before users use the remote training and testing service, which can ensure the security of the remote training and testing service and the security within the remote training and testing platform.

[0062] In the embodiment of the present application, after receiving the practical training test request, the management backend can parse the practical training test request, determine the current test requested by the user, and then query all test questions corresponding to the current test in the database.

[0063] The database is used to store all test questions corresponding to each test, as well as the corresponding relationship between each test and each verification script. For example, a test question management module can also be set in the remote training test platform, which is responsible for creating, modifying, deleting platform test questions and verifying user operation permissions.

[0064] Furthermore, the management backend can send all test questions to the user end, and then the user end can display the test questions; in addition, the management backend can also generate a container scheduling instruction and send it to the container module to start the container to enable the user to answer questions in the container.

[0065] Considering that some test questions may also have corresponding multimedia files, in some implementations, the remote training test platform provided in the embodiment of the present application further includes an object storage module, which, after determining all test questions corresponding to the current test based on the database, further includes:

[0066] The user end obtains the multimedia file corresponding to the test question from the object storage module in the form of a link and displays the multimedia file.

[0067] Specifically, after the management background queries the test questions and returns them to the user end, the user end can obtain the links to the multimedia files in the test questions while displaying the test questions. Then, the user end can obtain the multimedia files corresponding to the test questions from the object storage module through the links, and then dynamically load them into the page.

[0068] Among them, the multimedia files corresponding to each test question can be pre-stored in the object storage module by the management platform. After the multimedia files are stored in the object storage module, the object storage module can return a link for obtaining the multimedia file. The management background can write the link into the test question, which makes it convenient for the user end to obtain the multimedia file according to the link after obtaining the test question.

[0069] Through the above implementation, for test questions that contain multimedia files such as pictures, related multimedia files can be displayed together, and test questions in graphic and text form can be implemented to meet the practical training test needs in various scenarios.

[0070] S120. The container module responds to the container scheduling instruction, queries at least one current image file corresponding to the current test based on the database, and starts at least one container through all the current image files, so that the user can perform answering operations on the test questions in the started container.

[0071] The container module may include a container resource scheduling system and an image repository. Figure 2 As shown, in the container module, the container resource scheduling system is mainly responsible for the scheduling and management of the container.

[0072] In the embodiment of the present application, the container module can be used to unify the container image resources in the platform. The image file of the container can be entered by the cataloger in the front end of the remote training test platform, and the instruction is sent to the management background through the API. After receiving the instruction, the management background generates the image configuration file and packages the image. The packaged image file is stored in the image warehouse, and its author, authority, and the relationship between the test can be recorded in the database.

[0073] For example, Figure 3 This is a schematic diagram of image management provided by an embodiment of the present application, such as Figure 3 As shown, in terms of image management, after receiving the instructions sent by the front-end, the management background can verify its identity and permissions. After successful verification, it sends instructions to the container resource scheduling system through the preset API to complete the management operation, write to the image repository, and synchronize the relationship between the author, permissions, and tests to the database for storage.

[0074] Specifically, after receiving the container scheduling instruction, the container module may first query at least one current image file corresponding to the current test from the database, and then obtain the current image file from the image repository, and the container resource scheduling system starts the container through the current image file.

[0075] It should be noted that the container resource scheduling system can start one or more containers, the number of started containers can be determined by the current test, and the user can complete the answers to each test question in different containers.

[0076] For example, Figure 4 is a schematic diagram of container startup provided in an embodiment of the present application, such as Figure 4 As shown, the current practical training test includes question 1, question 2 and question 3, and the test containers started corresponding to the current practical training test include container 1 and container 2, wherein container 1 corresponds to question 1 and question 2, that is, the user completes the answer to question 1 and question 2 in container 1, and container 2 corresponds to question 3, that is, the user completes the answer to question 3 in container 2.

[0077] In the embodiment of the present application, in order to prevent a user from occupying too many container resources, a container quantity threshold may be pre-set. The container quantity threshold may adopt a uniform value or may be determined based on the user's identity information. When the container resource scheduling system starts a container for a user, the number of containers started should not exceed the container quantity threshold.

[0078] In addition, in the embodiment of the present application, in order to facilitate the isolation and management of each user and ensure that the tests between users do not affect each other, the container resource scheduling system can also create a namespace for each user, and each user's container is in its own namespace.

[0079] In a specific implementation, the remote training test platform provided in the embodiment of the present application further includes a cache module, which starts at least one container through all current image files, including:

[0080] The management backend determines whether there is a namespace corresponding to the user in the cache module; if so, the container module starts at least one container in the namespace corresponding to the user through all current image files.

[0081] The mapping relationship between the user and the namespace can be managed by the cache module. Specifically, the management backend can first search for the namespace corresponding to the user in the cache module. If it exists, the container module can further start all containers in the namespace. If it does not exist, the container module can first create a namespace corresponding to the user and write the mapping relationship to the cache module, and then the container module starts all containers in the namespace.

[0082] For example, Figure 5 is a schematic diagram of container scheduling provided by an embodiment of the present application, such as Figure 5 As shown, the container resource scheduling system starts containers in namespace 1, namespace 2, and namespace 3 for different users, and the number of started containers can be determined by tests.

[0083] Through the above implementation, each user's container can be started in the corresponding namespace, so that each user is isolated from each other through the namespace, and the user's network traffic will not be obtained by other users, thereby ensuring the security of remote training tests and facilitating user management.

[0084] In the embodiment of the present application, after at least one container is started for the user, the user can perform the answering operation to the test question in the started container. It should be noted that the user usually needs to answer the test questions in order, such as Figure 4 As shown, the user answers question 2 after answering question 1, and answers question 3 after answering question 2.

[0085] S130. In response to detecting the reply submission request from the user end, the management backend determines the container verification order according to the question answer order, and runs the corresponding verification script in each container in turn according to the container verification order, so as to verify the reply result in the container through the verification script.

[0086] Specifically, after completing the answers to all test questions, the user can submit the answer results on the user side. In response to detecting a user-triggered submission control or a user-input submission command, the user side can generate a reply submission request and send it to the management background.

[0087] Further, after receiving the reply submission request, the management backend can verify the reply result submitted by the user. In the embodiment of the present application, the reply result can be verified by a verification script, that is, whether the reply result is correct.

[0088] Specifically, after the user submits the answer result, the container verification order can be determined according to the test question answer order, where the test question answer order can be the answer order specified by the current test. The container verification order can be obtained according to the test question answer order and the correspondence between the test and the test questions, and the correspondence between the test and the container stored in the database.

[0089] Furthermore, the corresponding verification scripts can be run in each container in turn according to the container verification order. The management backend can determine the verification scripts that need to be run in each container according to the correspondence between the test and the test questions stored in the database, and the correspondence between the test and the verification script stored in the database, and then the management backend uses the API to issue verification instructions to the container module, so that the container module controls each container to run the verification script in turn.

[0090] by Figure 4For example, you can first run the verification script corresponding to question 1 in container 1, and then run the verification script corresponding to question 2 in container 1, or run the verification script that can verify questions 1 and 2 in turn in container 1, and after container 1 gets the result returned by the script, you can run the verification script corresponding to question 3 in container 2. It should be noted that the purpose of executing the verification script in the container in sequence according to the corresponding order between the questions and the containers is to create a test environment in sequence according to the content of the practical test, and verify in the environment in sequence after the test is completed, so as to realize customized testing and verification, and form a process-based practical test, thereby helping users complete the process-based test.

[0091] Specifically, after each container runs the corresponding verification script in turn, the management background can receive the results returned by the container, summarize the results returned by all containers, and obtain the test score of the user. For example, a test question verification module can be set in the remote training test platform, and the test question verification module determines whether the answer is correct based on the results returned by each container and summarizes the test score.

[0092] In a specific implementation, after running the corresponding verification script in each container in turn according to the container verification order, the following steps are also included:

[0093] Step 11: The management backend determines the user's test score based on the script execution results returned by all containers;

[0094] Step 12: The management backend sends the test results to the user end for display.

[0095] Among them, in step 11, the management background can send the script execution results returned by all containers to the test question verification module, and then the test question verification module determines the test score according to all script execution results.

[0096] Furthermore, in step 12, the test question verification module may send the test results to the management background, and the management background sends the test results to the user end, and then the user end displays the test results.

[0097] Through the above steps 11 and 12, feedback of test results can be achieved, allowing users to learn about the test results in a timely manner.

[0098] With respect to the above step 11, in one example, the management backend determines the test score of the user based on the script execution results returned by all containers, including:

[0099] For each container, the management background determines whether the response results in the container are correct based on the script execution results returned by the container; the management background determines the user's test score based on the correct response results and incorrect response results in all containers.

[0100] Specifically, for each container, the management background can call the test question verification module to determine whether the answer result in the container is correct based on the script execution result returned by the container, thereby integrating all correct answer results and incorrect answer results to obtain the user's test score.

[0101] Through the above example, it is possible to determine whether the answer is correct based on the script execution result, thereby obtaining the test score, which can ensure the accuracy of the test score.

[0102] In the embodiment of the present application, the verification of test questions can be divided into two categories, namely, no-error verification and comparison value verification. In the no-error verification, if the container does not return an error message after executing the script, it is determined that the answer is correct. In the comparison value verification, if the value returned by the container after executing the script is the same as the expected value, it is determined that the answer is correct.

[0103] In some implementations, the management backend determines whether the response result in the container is correct based on the script execution result returned by the container, including:

[0104] If the verification script running in the container is a non-error script, the management backend determines that the response result in the container is correct if there is no error information in the script execution result returned by the container;

[0105] Alternatively, if the verification script running in the container is a comparison value script, the management backend determines whether the value in the script execution result returned by the container is the same as the expected value, and if so, determines that the response result in the container is correct.

[0106] Specifically, if the verification script running in the container is a non-error script, that is, a non-error verification is implemented, then the response result in the container can be determined to be correct if there is no error information in the script execution result. If the verification script running in the container is a comparison value script, that is, a comparison value verification is implemented, then the response result in the container can be determined to be correct if the value in the script execution result is the same as the expected value.

[0107] Through the above implementation, error-free verification and comparison value verification are realized, and the verification of user tests is realized through multiple verification methods to ensure the accuracy of verification.

[0108] In the embodiment of the present application, considering that after starting at least one container for a user, there may be a user timeout, in order to avoid wasting resources, resources can also be recycled in time.

[0109] In one example, after starting at least one container through all current image files, the method further includes:

[0110] The container module obtains the container usage time of the user, and in response to detecting that the container usage time reaches the corresponding usable time of the user, the container module closes all containers started for the user.

[0111] Specifically, the container module can detect the user's container usage time in real time and compare it with the corresponding usable time of the user. If the container usage time reaches the usable time, all containers started for the user can be closed. The usable time is the time the user can use the container. The usable time can be a unified value or determined based on the user's identity information.

[0112] In an embodiment of the present application, in addition to passive resource recovery, active resource recovery can also be achieved. Active recovery can be initiated by the user. For example, the user can send a test end request to the management platform through the user terminal, and the management platform responds to the test end request and closes all containers started for the user.

[0113] Taking into account that during the remote training test, there may be situations where users expect a delay, in such situations, a delay can be provided for the user to avoid a situation where the container is closed before the user completes the test, resulting in test failure.

[0114] In some embodiments, the method provided in the embodiments of the present application further includes:

[0115] In response to detecting a delay request from the user end, the container module determines a delay amount based on the number of delay requests received and / or the user's identity information; the container module updates the corresponding available time of the user based on the delay amount.

[0116] The user may initiate a delay request by triggering a delay control on the user end, or may initiate a delay request by entering a delay command on the user end.

[0117] Specifically, if the container module receives a delay request from the user end, it can determine the delay amount according to the number of times the delay request from the user end is received. For example, the corresponding relationship between different times and different delay amounts can be preset, the lower the number, the greater the delay amount, and then the corresponding delay amount is queried according to the number.

[0118] Alternatively, if the container module receives a delay request from the user, the delay amount can be determined according to the user's identity information. For example, multiple permissions can be pre-divided, and different permissions have corresponding delay amounts. The user's permissions can be determined according to the user's identity information, thereby querying the corresponding delay amount.

[0119] Alternatively, the container module may determine the delay amount based on the number of delay requests received and the user's identity information. Exemplarily, the user's authority may be determined based on the user's identity information, thereby querying the corresponding delay amount as the basic delay amount, and then adjusting the basic delay amount based on the number of delay requests received to obtain the final delay amount. For example, if the number of delay requests is less than 2, the basic delay amount is maintained, and if the number of delay requests is greater than or equal to 2, the basic delay amount is reduced.

[0120] After obtaining the delay amount, the container module may further update the available time length corresponding to the user according to the delay amount, for example, based on the available time length, increase the delay amount to obtain a new available time length.

[0121] Through the above implementation, when the user has a delay demand, the available time for the user can be appropriately increased to avoid test failure caused by recycling resources before the user completes the test. In addition, the delay amount can be determined based on the number of delay requests received and / or the user's identity information, so that the delay can be carried out for the user in a targeted manner to ensure the accuracy of the delay.

[0122] In the embodiment of the present application, the storage of the user test environment can also be realized. In one example, the remote training test method provided by the embodiment of the present application also includes:

[0123] In response to detecting the reply submission request from the user, the management backend packages all containers started for the user for the current test into images and stores them.

[0124] Specifically, in response to detecting the reply submission request from the user, the management background can package all containers started for the user for the current test into an image file and store it, so that all containers of the user under the current test can be restarted later through the stored image file, so that the test environment and the reply results in the environment can be restored together, thereby achieving the purpose of retrieving the user's completed test at any time later.

[0125] In addition, the management background can also automatically retain the user's operation content while the user is answering the test questions and before the container is recycled, and then detect when the user reconnects to the container before the container is recycled. The user can continue to answer the questions on this basis, avoiding the user having to start from the beginning after the connection is disconnected.

[0126] The remote training test method provided by the embodiment of the present application is that the management background responds to the detection of the training test request from the user end, determines all the test questions corresponding to the current test based on the database, sends all the test questions to the user end for display, and generates a container scheduling instruction and sends it to the container module. The container module responds to the container scheduling instruction, queries at least one current image file corresponding to the current test according to the database, and starts at least one container through all the current image files, so that the user can perform the answer operation to the test question in the started container. Then, the management background responds to the detection of the reply submission request from the user end, determines the container verification order according to the test question answer order, and runs the corresponding verification script in each container in turn according to the container verification order to realize the verification of the reply result in the container. The method uses containers to create and manage the training test environment. After the user enters the test and sends a request, the training test environment can be quickly responded and deployed. After the user submits the reply result, the automatic verification can be completed without using a virtual machine, which solves the problems of large resource occupation, long startup and destruction time, complex resource cataloging, inflexible debugging and poor stability caused by virtual machines. Moreover, the method starts at least one container for the user, and can provide each user with an independent test environment. Unlike a centralized environment, operations between users will not affect each other, and the platform and the test environment are independent of each other, and will not affect each other when verifying the test answers. In addition, the method can start multiple containers for users, allowing users to answer questions in different containers respectively, forming a process-based practical training test, and verifying in sequence according to the order of answering questions, forming a process-based test verification, which can support tests composed of multiple test questions and meet various practical training test needs.

[0127] In an embodiment of the present application, container technology is used to create and manage a practical training test environment. After the user enters the test and issues a request to create a practical training test, the platform can quickly respond and deploy the practical training test environment. After the user submits the test answer, the platform can quickly recycle the resources occupied by the container into the system for other users to use in the test. In addition, an independent test environment can be provided for each user. Unlike a centralized environment, under this architecture, operations between users will not affect each other, and the platform and the test environment are independent of each other. The test results are judged through the RPC (Remote Procedure Call) protocol, and there is no impact on each other.

[0128] In addition, it supports a variety of test environments and software, such as Ubuntu, Centos, Fedora and other Linux operating systems, and various shell, Python, PHP and other test evaluation mechanisms. It supports editors to select operating systems and software to create test environments based on the content of practical training tests, and input test questions and verification codes through the platform to achieve customized test functions. It supports editors to upload practical training environments and test questions to the platform at any time without the user's awareness, without shutting down the environment.

[0129] The method provided in the embodiment of the present application also has the following technical effects:

[0130] 1. Fast deployment: Containers are lighter than traditional virtual machines, so their deployment and destruction responses will be faster and more convenient. The containerized deployment approach is more in line with users' performance expectations for the platform and enhances the user experience;

[0131] 2. Strong stability. The container module, database, cache module, etc. are all implemented with a distributed high-availability architecture. When the hardware device or operating system of a machine fails, the corresponding module services will not be interrupted, and the user's use of the platform will not be affected;

[0132] 3. Lower the operational threshold for catalogers: Compared with the complex virtual machine image production process, the container packaging process is relatively simple and can be connected to the platform for operation, so catalogers can more easily master its operation methods;

[0133] 4. Support multiple operating systems and software: The platform supports multiple operating systems such as centos, ubuntu, fedora, and multiple software such as MySQL, Hadoop, Spark, and multiple languages ​​such as Python, PHP, and JAVA, and can be applied to various training and testing scenarios;

[0134] 5. Support multi-container scheduling and verification: The platform supports single test settings, combining multiple training test environments, and supports unified scheduling and verification to meet diverse inspection needs;

[0135] 6. Strong security: The container environment verification test results can be directly executed through the container API without the need for third-party plug-ins or keys. This method can effectively protect against security issues caused by key leakage.

[0144] On the basis of the above implementation modes, optionally, the management backend is further used to determine the test score of the user based on the script execution results returned by all containers; and send the test score to the user terminal for display.

[0145] On the basis of the above-mentioned implementation modes, optionally, the management background is also used to determine, for each container, whether the response result in the container is correct based on the script execution result returned by the container; and determine the test score of the user according to the correct response results and incorrect response results in all containers.

[0146] On the basis of the above-mentioned implementation modes, optionally, the management backend is further used to, if the verification script running in the container is a non-error script, determine that the reply result in the container is correct if there is no error information in the script execution result returned by the container; or, the management backend is further used to, if the verification script running in the container is a comparison value script, determine whether the value in the script execution result returned by the container is the same as the expected value, and determine that the reply result in the container is correct if the same.

[0147] On the basis of the above-mentioned implementation modes, optionally, the platform also includes a security module, which is used to obtain the user's identity information in response to receiving a practical training test request sent by the user terminal; authenticate the user based on the user's identity information, and if the identity authentication passes, verify the user's authority based on the user's identity information; if the authority verification passes, forward the practical training test request to the management background.
