[0009] According to an embodiment of the present disclosure, a backup domain name for a web page is determined based on the following operations: constructing a primary-backup domain name mapping relationship according to an initial matching rule between the primary domain name and the backup domain name; modifying the initial matching rule in response to a request for change in operation and maintenance requirements to obtain a target matching rule; updating the primary-backup domain name mapping relationship according to the target matching rule to obtain an updated primary-backup domain name mapping relationship; and determining the target domain name to be a backup domain name for the web page when there is a backup domain name corresponding to the target domain name in the updated primary-backup domain name mapping relationship.

[0010] According to an embodiment of the present disclosure, a primary-backup domain name mapping relationship includes a primary domain name, a backup domain name, and a relationship status, wherein switching the resource primary domain name corresponding to the target resource type to the resource backup domain name includes: determining the primary domain name corresponding to the resource primary domain name from multiple primary domain names in the primary-backup domain name mapping relationship; when the relationship status corresponding to the primary domain name is a valid state, determining the backup domain name corresponding to the primary domain name as the resource backup domain name; and switching the resource primary domain name corresponding to the target resource type to the resource backup domain name.

[0011] According to an embodiment of the present disclosure, the primary domain name of a web page is determined based on the following operations: using a query tool to query the target primary domain name corresponding to the target web page from a database platform; when the target domain name is the same as the target primary domain name, determining the target domain name as the primary domain name of the web page.

Since it can be determined that the target page has been attacked by a network attack by accessing the target page based on the backup domain name of the web page, each time the target page that has been attacked by a network attack is accessed based on the backup domain name of the web page, it is automatically triggered to synchronously switch the multiple groups of resource primary domain names corresponding to the target resource type in the target page to the resource backup domain name, thereby ensuring the real-time access validity of the resources in the target page and avoiding the problem of invalid access to resources after the target page has been attacked by a network attack. The preset filtering rules further improve the efficiency of replacing multiple groups of resource primary domain names, and the switching and configuration of the primary and backup domain names do not need to rely on a third party, thereby improving security, autonomous controllability and flexibility.

[0027] In the process of implementing the present disclosure, it is found that with the increasing frequency of network attacks, setting a primary domain name and a backup domain name for a website is an effective way to improve the security of the website itself. The existing primary and backup domain name switching technology mainly resolves access requests through the domain name system, and switching and modifying the backup domain name depends on the domain name system serving a third party. In addition, after a web page is attacked, the content in the web page accessed based on the primary domain name may be in an invalid state. Therefore, it is necessary to synchronously replace the primary domain name contained in the web page content. However, for multiple primary domain names contained in the web page content, the existing technology cannot synchronously replace them with backup domain names in real time, and the replacement flexibility and scalability are poor.

[0028] In view of this, an embodiment of the present disclosure provides a method for switching between primary and backup domain names, which determines the target domain name in the page access request in response to a page access request for a target page; when the target domain name is a backup domain name of a web page, the resources in the target page are screened based on preset filtering rules to determine the target resource type, wherein the target resource type represents a high-access frequency element object that meets business needs; based on the primary and backup domain name mapping relationship, the resource primary domain name corresponding to the target resource type is switched to the resource backup domain name, wherein the primary and backup domain name mapping relationship represents a one-to-one correspondence between the primary domain name and the backup domain name.

[0029] It should be noted that the primary-backup domain name switching method and the primary-backup domain name switching device provided by the present disclosure can be used in the field of financial technology, such as financial institutions, and can also be used in any field other than the field of financial technology, such as e-commerce platforms such as shopping websites.

[0032] Figure 1 The application scenario diagram of the primary and backup domain name switching method according to an embodiment of the present disclosure is schematically shown.

[0033] like Figure 1 As shown, the application scenario 100 according to this embodiment may include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, and a server 105. The network 104 is used to provide a medium for a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103, and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0034] The user can use the first terminal device 101, the second terminal device 102, and the third terminal device 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications can be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only for example).

[0035] The first terminal device 101, the second terminal device 102, and the third terminal device 103 may be various electronic devices having display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0036] The server 105 may be a server that provides various services, such as a background management server (only as an example) that provides support for websites browsed by users using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server may analyze and process the received data such as user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0037] It should be noted that the primary and backup domain name switching method provided in the embodiment of the present disclosure can generally be executed by the server 105. Accordingly, the primary and backup domain name switching device provided in the embodiment of the present disclosure can generally be set in the server 105. The primary and backup domain name switching method provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Accordingly, the primary and backup domain name switching device provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105.

[0038] It should be understood that Figure 1 The number of the first terminal device, the second terminal device, the third terminal device, the network and the server in the embodiment is only for illustration. According to the implementation requirements, there may be any number of the first terminal device, the second terminal device, the third terminal device, the network and the server.

[0039] The following will be based on Figure 1 The scene described by Figure 2~Figure 3 The method for switching the primary and backup domain names in an embodiment of the present disclosure is described in detail.

[0040] Figure 2 The flowchart of the method for switching the primary and backup domain names according to an embodiment of the present disclosure is schematically shown.

[0041] like Figure 2 As shown, the primary-backup domain name switching method 200 of this embodiment includes operations S210 to S230.

[0042] In operation S210, in response to a page access request for a target page, a target domain name in the page access request is determined.

[0043] In operation S220, when the target domain name is a webpage backup domain name, resources in the target page are screened based on preset filtering rules to determine the target resource type.

[0044] In operation S230, based on the primary-backup domain name mapping relationship, the resource primary domain name corresponding to the target resource type is switched to the resource backup domain name.

[0045] According to an embodiment of the present disclosure, the target page is a web page interface to be accessed, and the server intercepts a page access request sent by a user through a request interceptor, parses the page access request, and obtains a target domain name in the page access request.

[0046] According to an embodiment of the present disclosure, the target domain name is the address of the target page, which is used to identify and access the target page. Through the target domain name, the user can directly access the resources on the target page.

[0047] According to an embodiment of the present disclosure, a primary-backup domain name mapping relationship is dynamically configured in a database, and the backup domain name information in the primary-backup domain name mapping relationship can be matched with the target domain name. If the match is successful, the target domain name is determined to be the backup domain name of the web page.

[0048] According to an embodiment of the present disclosure, when the target domain name is a backup domain name for a web page, triggering a traversal mechanism to traverse the resources in the target page includes: the server traversing the source code of the target page, the source code including the resources in the target page, and screening the resources in the target page based on preset filtering rules during the traversal process to determine the target resource type.

[0049] According to an embodiment of the present disclosure, the resources in the target page are all elements constituting the content and functions of the target page, and the elements can be correctly displayed and used by the browser on the target page.

[0050] For example, the resources in the target page may be style elements, image elements, audio elements, functional component elements, document elements, and the like.

[0051] According to an embodiment of the present disclosure, element objects with high access frequency are determined according to business needs and then the key resource types are determined. The key resource types can also be determined according to element objects with high security requirements and high importance in building the web page structure in the target page, for example, HyperText Markup Language (HTML) elements, script elements, functional component elements, hyperlink elements, etc.

[0052] According to an embodiment of the present disclosure, preset filtering rules are defined according to key resource types, and then resources in the target page that meet the preset filtering rules and correspond to the key resource types are screened to obtain target resource types. The target resource type represents a high-access frequency element object that meets business requirements.

[0053] According to an embodiment of the present disclosure, the primary-backup domain name mapping relationship represents a one-to-one correspondence between the primary domain name and the backup domain name.

[0054] According to an embodiment of the present disclosure, while determining that the resource type of a resource is the target resource type, the resource primary domain name of this resource is extracted from the response content, and the resource backup domain name corresponding to the resource primary domain name is determined according to the primary-backup domain name mapping relationship and replaced; until the resource primary domain names of all target resource types in the response content are switched to the resource backup domain name, the traversal is stopped.

[0055] According to an embodiment of the present disclosure, after the switching is completed, the resources requested in the response content are returned to the client based on the information in the request header (Request Headers) of the response content obtained by the server in response to the page access request, so that the resources in the target page can be displayed and used normally in the client's browser.

[0056] According to the embodiments of the present disclosure, since accessing the target page based on the backup domain name of the web page can determine that the target page has been attacked by a network attack, each time the target page after the network attack is accessed based on the backup domain name of the web page, the multiple groups of resource primary domain names corresponding to the target resource types in the target page are automatically triggered to be synchronously switched to the resource backup domain names, thereby ensuring the real-time access validity of the resources in the target page and avoiding the problem of invalid access to the resources after the target page is attacked by a network attack. The preset filtering rules further improve the efficiency of replacing multiple groups of resource primary domain names, and the switching and configuration of the primary and backup domain names do not need to rely on a third party, thereby improving security, autonomous controllability, and flexibility.

[0057] According to an embodiment of the present disclosure, the primary-backup domain name switching method includes: when the target domain name is the primary domain name of the web page and the primary domain name of the web page is an invalid domain name, based on the primary-backup domain name mapping relationship, switching the primary domain name of the web page to the backup domain name of the web page; accessing the target page based on the backup domain name of the web page.

[0058] According to an embodiment of the present disclosure, a target page corresponds to a main domain name of a web page. When the target domain name is the same as the main domain name of the web page, it is determined whether the main domain name of the web page is valid. When the main domain name of the web page is a valid domain name, the server directly returns the response content to the client.

[0059] According to an embodiment of the present disclosure, when the primary domain name of a web page is an invalid domain name, the primary-backup domain name mapping relationship is obtained from the database, the backup domain name of the web page corresponding to the primary domain name of the web page is determined from the primary-backup domain name mapping relationship, and the primary domain name of the web page is switched to the backup domain name of the web page.

[0060] According to an embodiment of the present disclosure, the target page is accessed again based on the backup domain name of the web page, triggering a traversal mechanism to filter out all target resource types, and switching the resource primary domain name corresponding to the target resource type to the resource backup domain name. After all resource primary domain names are switched, the server returns the response content to the client.

[0061] According to an embodiment of the present disclosure, if the target domain name is the primary domain name of the web page and is a valid domain name, it means that the target page can be safely accessed, and the target page is directly accessed and the response content is returned; if the target domain name is the primary domain name of the web page and is an invalid domain name, it means that the target page is in a non-safe access state and needs to be replaced with the backup domain name of the web page for access. The access based on the backup domain name of the web page triggers the switching of the primary domain names of the resources of each target resource type, thereby ensuring the effectiveness and security of resource access in the target page and improving data security.

[0062] According to an embodiment of the present disclosure, when the target domain name is a backup domain name for a web page, the resources in the target page are screened based on preset filtering rules, and determining the target resource type includes: determining resource access requirements from the acquired business resource access performance; based on the resource access requirements, determining preset filtering rules; when the target domain name is a backup domain name for a web page, triggering a traversal mechanism to traverse the source code corresponding to the target page; using regular matching rules, mapping at least one resource address of the source code, and determining the resource type corresponding to each of the at least one resource addresses; based on the preset filtering rules, determining the target resource type from at least one resource type.

[0063] According to an embodiment of the present disclosure, business resource access performance is obtained by analyzing historical access requests to a target page. The business resource access performance is the performance generated by accessing resources in the target page, such as resource access frequency, resource access time, response time, etc.

[0064] According to an embodiment of the present disclosure, high-access frequency resources, important resources, and high-security resources are determined from the acquired business resource access performance, and then resource access requirements are determined based on the high-access frequency resources, important resources, and high-security resources. Key resource type parameters are constructed based on the resource access requirements, and preset filtering rules are designed based on the key resource type parameters.

[0065] According to an embodiment of the present disclosure, when the target domain name is a backup domain name of a web page, a traversal mechanism is triggered to traverse the source code corresponding to the target page, and the source code defines the structure and resource content of the target page.

[0066] According to an embodiment of the present disclosure, the resource address of the source code is mapped using regular matching rules to determine the resource type corresponding to the resource address. For example, if the page access request is http: / / www.xxx.com.cn / test.html, the resource address: / test.html is mapped according to the regular matching rules to obtain the resource type text / html.

[0067] For example, the regular matching rule may be "~(.*xxx)$", and the resource type corresponding to the resource address ".mp4" is video / mp4.

[0068] According to an embodiment of the present disclosure, a target resource type is determined from at least one resource type in a source code according to a plurality of key resource types defined in a preset filtering rule.

[0069] According to an embodiment of the present disclosure, the resources of the target page are filtered to exclude some static resources such as pictures and styles, and the target resource type is screened out, and then the resource primary domain name corresponding to the target resource type is replaced with the resource backup domain name, thereby improving the efficiency of replacing the resource primary and backup domain names.

[0070] According to an embodiment of the present disclosure, resource access requirements include key content access requirements and dynamic resource access requirements; wherein, based on the resource access requirements, determining preset filtering rules includes: determining a target resource type variable value based on the key content access requirements and the dynamic resource access requirements, wherein the key content access requirement represents a requirement that the frequency and importance of accessing key content are both higher than a preset requirement threshold; and constructing preset filtering rules based on the target resource type variable value.

[0071] According to an embodiment of the present disclosure, the key content access requirement is a requirement for accessing key resources of high frequency and importance. For example, key resources include functional component elements, hyperlink elements, and the like.

[0072] According to an embodiment of the present disclosure, the dynamic resource access requirement is a requirement for accessing dynamic resources of a target page. Dynamic resources are resources that are dynamically generated or changed as needed when an application is running. For example, dynamic resources include script elements, style elements, hypertext markup language elements, etc.

[0073] According to an embodiment of the present disclosure, target resources are determined based on key content access requirements and dynamic resource access requirements, and the target resources include key resources and dynamic resources. The target resource type variable value is determined based on the resource type of the target resource. The judgment conditions are defined in the preset filtering rules based on the resource type variable and the target resource type variable value to be screened.

[0074] For example, if the target resource is a style element or a script element, the target resource type variable value is determined to be "text / css" or "application / javascript" according to the resource type of the target resource, and the judgment condition is constructed as IF (xxx_content_type == "text / css" or xxx_content_type == "application / javascript", where the resource type variable is xxx_content_type.

[0075] According to an embodiment of the present disclosure, a backup domain name for a web page is determined based on the following operations: constructing a primary-backup domain name mapping relationship according to an initial matching rule between the primary domain name and the backup domain name; modifying the initial matching rule in response to a request for change in operation and maintenance requirements to obtain a target matching rule; updating the primary-backup domain name mapping relationship according to the target matching rule to obtain an updated primary-backup domain name mapping relationship; and determining the target domain name to be a backup domain name for the web page when there is a backup domain name corresponding to the target domain name in the updated primary-backup domain name mapping relationship.

[0076] According to an embodiment of the present disclosure, the initial matching rule can be obtained from the shared database platform, and the primary and backup domain name mapping relationship is constructed in the configuration file of the database according to the initial matching rule between the primary domain name and the backup domain name. The initial matching rule defines a one-to-one correspondence between the primary domain name and the backup domain name.

[0077] According to the embodiments of the present disclosure, operation and maintenance personnel can modify and expand the correspondence between the primary and backup domain names according to actual needs. In response to the operation and maintenance personnel's request for change in operation and maintenance needs, the initial matching rules are modified to obtain target matching rules. The target matching rules define a one-to-one correspondence between the modified primary domain name and the backup domain name.

[0078] According to an embodiment of the present disclosure, the primary-backup domain name mapping relationship is modified according to the target matching rule to obtain an updated primary-backup domain name mapping relationship.

[0079] According to an embodiment of the present disclosure, the primary-backup domain name mapping relationship is dynamically updated in real time according to actual needs. After responding to a page access request, the target domain name in the page access request is matched with the backup domain name information in the primary-backup domain name mapping relationship at the response time. If the match is successful, the target domain name is determined to be the backup domain name of the web page.

[0080] According to the embodiments of the present disclosure, operation and maintenance personnel can dynamically update the primary and backup domain name mapping relationships in the database according to actual needs, ensure the real-time validity of the primary and backup domain name mapping relationships, and improve the accuracy of primary and backup domain name replacement.

[0081] According to an embodiment of the present disclosure, a primary-backup domain name mapping relationship includes a primary domain name, a backup domain name, and a relationship status, wherein switching the resource primary domain name corresponding to the target resource type to the resource backup domain name includes: determining the primary domain name corresponding to the resource primary domain name from multiple primary domain names in the primary-backup domain name mapping relationship; when the relationship status corresponding to the primary domain name is a valid state, determining the backup domain name corresponding to the primary domain name as the resource backup domain name; and switching the resource primary domain name corresponding to the target resource type to the resource backup domain name.

[0082] According to an embodiment of the present disclosure, the primary-backup domain name mapping relationship includes a relationship identifier, a primary domain name, a backup domain name, a relationship status, a creation date, and an update date.

[0083] Table 1 shows the table of the meanings of fields in the primary and standby domain name mapping relationship according to an embodiment of the present disclosure.

[0084]

[0085] According to an embodiment of the present disclosure, the relationship status includes a valid status and an invalid status. is_deleted being 0 indicates that this group of primary and standby domain name mapping relationships has been deleted and is in an invalid status; is_deleted being 1 indicates that this group of primary and standby domain name mapping relationships has not been deleted and is in a valid status.

[0086] Table 2 shows the primary and standby domain name mapping relationship table according to an embodiment of the present disclosure.

[0088] According to an embodiment of the present disclosure, in response to a page access request http: / / target domain name / index.html for a target page, it is determined that the target domain name is the primary web domain name A; when the primary web domain name A is a valid domain name, the target page is accessed, and the source code of the target page is obtained " <link type="text / css" href=" / / 资源主域名B / test.css"> <script src=" / / resource primary domain name C / test.js ", traverse the source code to obtain the resource primary domain name B and the resource primary domain name C.

[0089] According to an embodiment of the present disclosure, when the primary web domain name A is an invalid domain name, according to the primary and standby domain name mapping relationship, the primary web domain name A is switched to the standby web domain name B, and the target page is accessed based on the standby web domain name A to obtain a page access request http: / / standby web domain name A / index.html, triggering the traversal of the source code, and performing resource primary domain name switching according to the primary and standby domain name mapping relationship to obtain the switched source code " <link type="text / css" href=" / / 资源备域名B / test.css"> <script src=" / / resource standby domain name C / test.js ", and then return the response content to the client according to the switched source code.

[0090] Figure 3 Schematically shows the flowchart of processing a page access request according to an embodiment of the present disclosure.

[0091] As Figure 3As shown, the server intercepts the page access request sent by the user through the request interceptor, parses the page access request, and obtains the target domain name in the page access request. Determine whether the target domain name is the main domain name of the web page. When the target domain name is the main domain name of the web page and the main domain name of the web page is a valid domain name, the server directly returns the response content to the client; when the main domain name of the web page is an invalid domain name, the main domain name of the web page is replaced with the backup domain name of the web page, and the target page is accessed based on the backup domain name of the web page to obtain a page access request; the target domain name in the page access request is judged again, and it is determined that the target domain name is the backup domain name of the web page, and the traversal mechanism is triggered to traverse the resources in the target page. During the traversal process, the resources in the target page are screened based on the preset filtering rules. When the resource type corresponding to the resource does not meet the preset filtering rules, the resource is directly returned to the client; otherwise, the resource main domain name of this resource is replaced with the resource backup domain name according to the mapping relationship between the primary and backup domain names, and then the resource is returned to the client.

[0092] According to the embodiments of the present disclosure, operation and maintenance personnel can maintain the original mapping relationship in the database. If the primary and backup domain name mapping relationship needs to be updated, the dynamic reading module on the system will periodically read and update the primary and backup domain name mapping relationship.

[0094] According to an embodiment of the present disclosure, a query tool is used to query a target primary domain name corresponding to a target web page from a shared database platform, and when the target domain name is the same as the target primary domain name, the target domain name is determined to be the primary domain name of the web page.

[0095] According to an embodiment of the present disclosure, one target page corresponds to one main domain name of the web page. When the target domain name is the same as the main domain name of the web page, the target domain name is determined to be the main domain name of the web page.

[0096] According to an embodiment of the present disclosure, whether the target domain name is the primary domain name of the web page can be judged according to the level of the target domain name, including: when the level of the target domain name is the highest level domain name, determining the target domain name as the primary domain name of the web page, otherwise it is a backup domain name of the web page.

[0097] According to the embodiments of the present disclosure, the efficiency of determining the webpage domain name and the matching accuracy can be accelerated by combining query tools, domain name levels, etc.
