[0023] The various aspects of the present invention are described in detail below in conjunction with the accompanying drawings and specific embodiments. Among them, well-known modules, units and their connections, links, communications or operations are not shown or described in detail. In addition, the described features, architectures or functions can be combined in any way in one or more embodiments. It should be understood by those skilled in the art that the various embodiments described below are only used for illustration and are not intended to limit the scope of protection of the present invention. It can also be easily understood that the modules or units or processing methods in each embodiment described herein and shown in the accompanying drawings can be combined and designed in various different configurations.
[0024] [Example 1]
[0025] Figure 14 is a flow chart of a configuration file detection method according to Embodiment 1 of the present invention.
[0026] like Figure 1 As shown, in Embodiment 1 of the present invention, the configuration file detection method may include: step S11, step S12, step S13, step S14 and step S15, and the above steps are described in detail below.
[0027] In step S11, the check rules of the configuration file are obtained and stored in a database, wherein the check rules include key check rules and value check rules.
[0028] In some implementations, the check rule includes but is not limited to at least one of the following: key exists, key does not exist, key value contains keyword, key value does not contain keyword, dependent check rule, value exists, value does not exist, value value contains keyword, value value does not contain keyword, value value equals keyword. The dependent check rule is: when performing a key or value check, other key or value values are required to meet the conditions.
[0029] In this embodiment, by setting the inspection rules between key and value and saving them in the database, it is convenient to query and obtain the corresponding detection rules during subsequent inspections. Among them, the inspection rules between key and value include but are not limited to: contain, not contain, equal, not exist, exist, as well as the dependency relationship between rules and the validity of rules.
[0030] In step S12, the configuration file is obtained, the configuration file is parsed to generate parsing information, and the parsing information is stored in the database, wherein the parsing information includes: a key prefix prefix_key, a key key, and a value value. By parsing the obtained configuration file content and saving the corresponding parsing information in the database, subsequent queries can be facilitated.
[0031] In some implementations, the configuration file includes a YAML format file and a properties format file. Wherein, when the configuration file is a YAML file, obtaining the configuration file and parsing the configuration file to generate parsing information includes: reading the YAML file, parsing the content of the YAML file and converting it into dictionary type data; and traversing the dictionary type data to generate the parsing information.
[0032] In this embodiment, parsing the properties configuration file includes: reading the configuration items by line (key=value), and splitting the configuration items to obtain the configuration information. The part before the last "." in the key is the key prefix prefix_key. For example, for the data "spring.datasource.username=hcfc" in the properties configuration file, the parsed information containing prefix_key, key, and value is: spring.datasource, spring.datasource.username, hcfc, and prefix_key, key, value, and file name are saved in the database.
[0033] Parsing the yaml configuration file includes: first, after reading the content of the yaml configuration file, converting the file content into dictionary type data, the dictionary structure data includes dictionary key and dictionary value; second, recursively traversing the dictionary type data, recording each layer of dictionary key during traversal, if the dictionary value is a list object, traversing the list object, if the dictionary value is a dictionary, recursively traversing the dictionary, if the dictionary value is neither a list object nor a dictionary, the parent node of the dictionary, the dictionary, and the value are saved in the database as prefix_key, key, and value respectively.
[0034] In step S13, the checking rules in the database and the parsing information corresponding to the configuration file to be checked are obtained. In this embodiment, the checking rules in the database and the corresponding parsing information are dynamically read.
[0035] In step S14, the parsed information is checked according to the checking rule to determine whether the parsed information is compliant.
[0036] In some embodiments, when the inspection rule is a dependent inspection rule, obtaining the inspection rule in the database and the parsing information corresponding to the configuration file to be inspected, and detecting the parsing information according to the inspection rule includes: obtaining the first parsing information to be detected in the database; obtaining the second parsing information that the first parsing information depends on according to the key prefix in the first parsing information and the dependent inspection rule; obtaining the second inspection rule corresponding to the second parsing information; and detecting the first parsing information and the second parsing information according to the dependent inspection rule and the second inspection rule.
[0037] In a further embodiment, when the second parsed information fails the check according to the second check rule, the first parsed information is no longer tested, and the test result is directly determined to be failed / non-compliant.
[0038] Among them, when a check rule depends on another check rule, the two rules are in the same parent node. For example, key1 is spring.datasource.test.drive and key2 is spring.datasource.test.url, then the parent nodes of key1 and key2 are the same. When it is necessary to determine whether the value of spring.datasource.test.drive (key1) matches the value of spring.datasource.test.url (key2), since there may be multiple databases in a configuration file (such as spring.datasource.test or spring.datasource.auto), the execution of the dependency check rule needs to be checked in the parent node spring.datasource.test determined by the key prefix, so as to ensure the accuracy of the dependency check and avoid checking the dependent rules incorrectly.
[0039] In step S15, when the parsed information is not compliant, a prompt message is generated, and the non-compliant parsed information is displayed.
[0040] In a further implementation manner, non-compliant parsing information is deleted or modified to improve the security and stability of the service in production.
[0041] The above-mentioned configuration file detection method of Example 1 of the present invention is adopted, by obtaining the inspection rules, parsing the configuration file to generate parsing information, and checking the parsing information according to the inspection rules stored in the database and the parsing information corresponding to the configuration file to be checked, so as to determine whether the parsing information is compliant. The configuration file can be checked in the software testing stage, and problems in the configuration can be discovered in advance and corrected in time. Therefore, it can be ensured that the problem has been fixed before going online to avoid the problem from being brought to production, thereby improving the safety and stability of production, and helping testers to reduce configuration file testing.
[0042] [Example 2]
[0043] Figure 2 4 is a flow chart of a configuration file detection method according to Embodiment 2 of the present invention.
[0044] like Figure 2 As shown, in Embodiment 2 of the present invention, the configuration file detection method may include the following steps:
[0045] (1) Setting the check rules of the configuration file through the web page and storing the check rules in the database. The check rules include but are not limited to at least one of the following: key exists, key does not exist, key value contains the keyword, key value does not contain the keyword, dependent check rules, value exists, value does not exist, value value contains the keyword, value value does not contain the keyword, value value is equal to the keyword.
[0046] (2) Reading a configuration file to be checked, parsing the configuration file to generate parsing information, and storing the parsing information in the database.
[0047] (3) When checking the configuration file, the parsing information (configuration items) and the check rules stored in the database are read out in real time, the check rules are traversed, and the configuration items are compared with the setting rules to check whether the configuration items comply with the rules. For example, if the rule checks the key, then check whether the key exists in the configuration item and whether the key value matches the check rule. The configuration items that do not comply with the rule are saved in the database. If the check rule has dependent rules, the dependent rules are matched first. If the match fails, the rule is no longer checked and the next rule is checked.
[0048] Exemplarily, the test configuration file is in properties format or yaml format, and the file content is parsed in the form of key=value, for example: prefix.key1=value2, prefix.key2=value2, and check whether the value is set correctly according to the keyword key, or when the key1 value is value1, whether the key2 value is set correctly.
[0049] (4) When the check is completed, the database is checked to see whether there are any configuration items that do not comply with the rules. If so, a prompt is given that the configuration file check has failed, and information about the non-compliant configuration items is displayed on a web page.
[0050] By adopting the above-mentioned configuration file detection method of Example 2 of the present invention, it is possible to perform configuration file inspection in the software testing stage, discover problems in the configuration in advance and correct them in time. Therefore, it is possible to ensure that the problems have been fixed before going online, avoid problems from being brought to production, thereby improving the safety and stability of production, and helping testers reduce configuration file testing.

Wherein, when the configuration file is a YAML file, obtaining the configuration file and parsing the configuration file to generate parsing information includes: reading the YAML file, parsing the content of the YAML file and converting it into dictionary type data; and traversing the dictionary type data to generate the parsing information.
[0058] The file detection module 330 is used to obtain the inspection rules in the database and the parsing information corresponding to the configuration file to be checked, detect the parsing information according to the inspection rules, and determine whether the parsing information is compliant.
[0059] In some embodiments, when the inspection rule is a dependent inspection rule, obtaining the inspection rule in the database and the parsing information corresponding to the configuration file to be inspected, and detecting the parsing information according to the inspection rule includes: obtaining the first parsing information to be detected in the database; obtaining the second parsing information that the first parsing information depends on according to the key prefix in the first parsing information and the dependent inspection rule; obtaining the second inspection rule corresponding to the second parsing information; and detecting the first parsing information and the second parsing information according to the dependent inspection rule and the second inspection rule.
[0060] In a further embodiment, when the second parsed information fails the check according to the second check rule, the first parsed information is no longer tested, and the test result is directly determined to be failed / non-compliant.
[0061] The detection result display module 340 is used to generate prompt information when the parsing information is not compliant, and to display the non-compliant parsing information.
[0062] In a further implementation manner, non-compliant parsing information is deleted or modified to improve the security and stability of the service in production.
