[0023] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood, however, that the description which follows is merely exemplary and is not intended to limit the scope of the present disclosure. In the following detailed description of embodiments of the present disclosure, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure.

In other instances, well-known structures and functions have not been described in detail in order to avoid obscuring the concepts of the present disclosure.

[0024] The terms used herein are merely used to describe specific embodiments and are not intended to limit the present disclosure. The terms "include", "comprise", and the like used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0025] All terms used herein, including technical and scientific terms, have the same meanings as those generally understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having meanings consistent with the context of the present specification, and should not be interpreted in an idealized or excessively formal manner.

[0026] In the case of using expressions similar to "at least one of A, B, and C, etc.", it should generally be interpreted to include at least one of the items, unless otherwise defined (for example, "a system having at least one of A, B, and C" should include but not be limited to a system having A alone, a system having B alone, a system having C alone, a system having both A and B, a system having both A and C, a system having both B and C, and / or a system having A, B, and C together, etc.).

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

[0028] Therefore, an embodiment of the present disclosure provides a primary and backup domain name switching method. In response to a page access request for a target page, a target domain name in the page access request is determined. In a case where the target domain name is a backup domain name of a webpage, resources in the target page are screened based on a preset filtering rule to determine a target resource type, wherein the target resource type represents a high-access-frequency element object that meets a business requirement. A resource primary domain name corresponding to the target resource type is switched into a resource backup domain name based on a primary and backup domain name mapping relationship, 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.

Figure 1 Figures 2-3 The primary and backup domain name switching method according to the embodiment of the disclosure will be described in detail based on the scenario described above.

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

[0041] As shown in Figure 2 The primary and backup domain name switching method 200 of the embodiment includes operations S210-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, in the case that the target domain name is a web page backup domain name, resources in the target page are filtered based on a preset filtering rule, and a target resource type is determined.

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

[0045] According to the embodiment of the disclosure, the target page is a web interface to be accessed, and the server intercepts a page access request sent by a user through a request interceptor, analyzes 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 an address of a target page, and a user can directly access resources on the target page through the target domain name.

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

[0048] According to an embodiment of the present disclosure, in a case where the target domain name is a backup domain name of a webpage, triggering the traversal mechanism to traverse resources in the target page includes: traversing, by a server, source code of the target page, the source code including the resources in the target page, and filtering, in the traversal process, the resources in the target page based on a preset filtering rule to determine a target resource type.

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

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

[0051] According to an embodiment of the present disclosure, the element object with a high access frequency is determined according to a business requirement, and then a key resource type is determined. The key resource type can also be determined according to an element object with a high security requirement and a high importance in constructing a webpage structure, for example, a HyperText Markup Language (HTML) element, a script element, a functional component element, and a hyperlink element.

[0052] According to an embodiment of the present disclosure, the preset filtering rule is defined according to the key resource type, and then a resource corresponding to the key resource type defined in the preset filtering rule is filtered from the resources in the target page, to obtain the target resource type. The target resource type represents an element object with a high access frequency that meets a business requirement.

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

[0054] According to an embodiment of the present disclosure, when the resource type of a resource is determined to be the target resource type, a resource master domain name of the resource is extracted from the response content, a resource backup domain name corresponding to the resource master domain name is determined according to the master-backup domain name mapping relationship, and the replacement is performed. The traversal is stopped until all resource master domain names of the target resource types in the response content are switched to resource backup domain names.

[0055] According to an embodiment of the present disclosure, after the switching is completed, information in Request Headers of response content obtained by the server in response to the page access request is returned to the client, and the resources in the target page are normally displayed and used in the browser of the client.

[0056] According to an embodiment of the present disclosure, since the target page can be determined to be attacked by the network attack based on the webpage backup domain name, and the multiple sets of resource primary domain names corresponding to the target resource types in the target page are automatically triggered to be switched to the resource backup domain names, the real-time access validity of the resources in the target page is ensured, the problem of invalid access of the resources after the target page is attacked by the network attack is avoided, the preset filtering rules further improve the efficiency of the replacement of the multiple sets of resource primary domain names, the switching and configuration of the primary and backup domain names do not need to depend on the third party, and the security, self-controllability and flexibility are improved.

[0057] According to an embodiment of the present disclosure, the primary and backup domain name switching method comprises: in the case that the target domain name is a webpage primary domain name and the webpage primary domain name is an invalid domain name, switching the webpage primary domain name to a webpage backup domain name based on a primary and backup domain name mapping relationship; and accessing the target page based on the webpage backup domain name.

[0058] According to an embodiment of the present disclosure, one target page corresponds to one webpage primary domain name, in the case that the target domain name is the same as the webpage primary domain name, it is determined whether the webpage primary domain name is valid, and in the case that the webpage primary domain name is a valid domain name, the server directly returns the response content to the client.

[0059] According to an embodiment of the present disclosure, in the case that the webpage primary domain name is an invalid domain name, the primary and backup domain name mapping relationship is obtained from a database, the webpage backup domain name corresponding to the webpage primary domain name is determined from the primary and backup domain name mapping relationship, and the webpage primary domain name is switched to the webpage backup domain name.

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

[0061] According to an embodiment of the present disclosure, if the target domain name is a web page main domain name and is a valid domain name, it is represented that the target page can be safely accessed, the target page is directly accessed, and the response content is returned; if the target domain name is a web page main domain name and is an invalid domain name, it is represented that the target page handles a non-safe access state, needs to be replaced by a web page backup domain name for access, and based on the web page backup domain name access, the respective resource main domain names of the switching target resource types are triggered, the effectiveness and safety of resource access in the target page are ensured, and the data security is improved.

[0062] According to an embodiment of the present disclosure, in the case that the target domain name is a web page backup domain name, the resources in the target page are screened based on a preset filtering rule, and the target resource type is determined, including: determining resource access demand from the obtained business resource access performance; determining the preset filtering rule based on the resource access demand; in the case that the target domain name is a web page backup domain name, triggering a traversal mechanism to traverse the source code corresponding to the target page; using a regular matching rule to map at least one resource address of the source code to determine the respective resource types corresponding to the at least one resource address; and determining the target resource type from the at least one resource type based on the preset filtering rule.

[0063] According to an embodiment of the present disclosure, the business resource access performance is obtained by analyzing the historical access requests to the target page, and the business resource access performance is the performance generated by accessing the 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, the high-access-frequency resources, the important resources, and the high-security resources are determined from the obtained business resource access performance, and then the resource access demand is determined according to the high-access-frequency resources, the important resources, and the high-security resources, the key resource type parameters are constructed based on the resource access demand, and the preset filtering rule is designed according to the key resource type parameters.

[0065] According to an embodiment of the present disclosure, in the case that the target domain name is a web page backup domain name, 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, a regular matching rule is used to map the resource address of the source code to determine the resource type corresponding to the resource address, for example, the page access request is http: / / www.xxx.com.cn / test.html, and the resource address: / test.html is mapped to obtain the resource type text / html according to the regular matching rule.

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

[0068] According to an embodiment of the present disclosure, the target resource type is determined from at least one resource type in the source code according to a plurality of key resource types defined in the 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 backup domain name of the resource main domain name corresponding to the target resource type is replaced, thereby improving the efficiency of resource main backup domain name replacement.

[0070] According to an embodiment of the present disclosure, the resource access requirement includes key content access requirement and dynamic resource access requirement; wherein, based on the resource access requirement, the preset filtering rule is determined, including: determining a target resource type variable value according to the key content access requirement and the dynamic resource access requirement, wherein the key content access requirement represents a requirement that the frequency and importance of accessing key content are higher than a preset requirement threshold; and constructing the preset filtering rule according to 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 high-frequency and important key resources. For example, the key resources include functional component elements, hyperlink elements, etc.

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

[0073] According to an embodiment of the present disclosure, the target resource is determined according to the key content access requirement and the dynamic resource access requirement, the target resource includes the key resource and the dynamic resource, the target resource type variable value is determined according to the resource type of the target resource, and the judgment condition is defined in the preset filtering rule according to the resource type variable and the target resource type variable value to be screened.

[0074] For example, the target resource is a style element and a script element, the target resource type variable value is determined 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), wherein the resource type variable is xxx_content_type.

[0075] According to an embodiment of the present disclosure, the webpage backup domain name 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 change request of an operation and maintenance requirement 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 as the webpage backup domain name in a case where the updated primary-backup domain name mapping relationship contains a backup domain name corresponding to the target domain name.

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