It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a content caching method and system based on user rights, according to the rights dimensions in content viewing rights information corresponding to a publishing range, according to a preset caching structure, rights content lists corresponding to the rights dimensions are respectively constructed, published contents are respectively added to the corresponding rights content lists, and therefore caching of the published contents is completed, and the technical problem that existing contents are usually stored in a database, when a system wants to acquire the contents of viewing rights of a current user, the contents need to be queried from the database, but when the data volume is large, the querying efficiency is extremely low due to the bottleneck of the database is solved.
The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a content caching method based on user rights according to an embodiment of the present application. As shown in fig. 1, a content caching method based on user rights provided in an embodiment of the present application mainly includes the following steps:
s101, determining the distribution range of the distributed content, and storing the distributed content in a database.
Before content distribution, the server acquires basic information of the currently distributed content and a content distribution range configured by a system administrator or a content owner. When the content is released, the server determines which releasing ranges of the released content are specific, updates the state of the content, and stores the basic information and the releasing ranges of the released content in the database. The content may include news, information, articles, the basic information includes ID, title, text, and the distribution range indicates to which users the current content is distributed.
S102, according to the content viewing permission information corresponding to the release range and the permission dimension in the content viewing permission information, respectively constructing a permission content list corresponding to the permission dimension according to a preset cache structure.
When the basic information and the release range of the released content are stored in the database, the server determines content viewing authority information corresponding to the release range according to the content release range obtained when the content is released, and then according to the authority dimension in the content viewing authority information and a preset cache structure, an authority content list corresponding to the current authority dimension is respectively constructed and named. For example, the rights content list is named: permission dimension _ permission dimension identification. The content viewing permission information indicates which users are allowed to view the currently published content, and the preset cache structure indicates a format corresponding to the permission content list for caching the published content.
In one embodiment of the application, the server acquires a publishing range of the content when the content is published, and defines users allowed to view the currently published content in the publishing range, wherein the publishing range configured when the content is published corresponds to the content viewing authority information. Meanwhile, the content viewing permission information comprises the permission dimension of the user and specific dimension information corresponding to the permission dimension. Wherein the permission dimension represents a dimension for classifying the user.
And the server respectively constructs a corresponding authority content list according to the specific dimension information so as to determine the content which is allowed to be viewed by the user and corresponds to the specific dimension information. In this embodiment, the rights content lists are respectively constructed according to the specific dimension information corresponding to the rights dimensions, and therefore, the specific dimension information corresponds to the rights content lists one to one. Therefore, the content is processed according to the user right in the content management system, and the relationship between the user right and the content is maintained.
In an embodiment of the application, the server determines the content specifically included in the content viewing permission information according to the content viewing permission information corresponding to the content publishing range. The content viewing permission information comprises permission dimensions of at least any one of a user, an organization and a role, and each permission dimension respectively comprises corresponding user information, organization information and role information.
The server checks the authority dimension in the authority information according to the content corresponding to the release range, and respectively constructs an authority content list corresponding to the authority dimension according to a preset cache structure, and actually, respectively constructs the authority content list corresponding to the authority dimension according to user information, organization information and role information which specifically correspond to the authority dimension.
Specifically, fig. 2 is a schematic diagram of a rights content caching policy provided in an embodiment of the present application. As shown in fig. 2, the published content is cached as follows:
first, the server determines, through the distribution range configured at the time of content distribution, the user U003, the user U004, the organization ORG001, and the role R002 that are allowed to access the current content, thereby identifying the authority dimension: USER (USER), Organization (ORG), and ROLE (ROLE).
Secondly, the server, according to the authority dimension: the method comprises the steps that a USER (USER), an Organization (ORG) and a ROLE (ROLE) are respectively constructed, corresponding authority content lists are constructed, and the constructed authority content lists are determined to be USER _ U003, USER _ U004, ORG _ ORG001 and ROLE _ R002 according to specific dimension information.
And S103, adding the published contents into corresponding authority content lists respectively, and storing the contents into a cache.
The server finds the corresponding authority content list according to the specific user information, organization information and role information which are allowed to be checked in the content issuing range, and respectively adds the issued content to the corresponding authority content list and stores the issued content in the cache, so that when the current user has a content checking request, the content identification is directly obtained from the corresponding authority content list in the cache, and the query efficiency is improved.
In one embodiment of the application, before adding the published content to the corresponding rights content list, the server first determines the identifier of the published content, and then adds the identifier of the published content to the rights content list corresponding to the user information, the organization information and the role information, respectively. Therefore, the cache space can be saved, the utilization rate of resources is improved, the energy consumption of the whole network is reduced, and the efficiency of content query is improved.
Fig. 3 is a flowchart of another content caching method based on user rights according to an embodiment of the present application. As shown in fig. 3, before content distribution, a system administrator or a content owner configures a distribution range of content. When the content is released, the server updates the state of the content and stores the basic information and the release range of the released content in the database.
Meanwhile, the server creates a new thread and acquires the distribution range of the content determined when the content is distributed. And the server determines the authority dimension in the content viewing information according to the content viewing authority information corresponding to the issuing range, and respectively constructs an authority content list corresponding to the current authority dimension according to the specific dimension information corresponding to the current authority dimension. And the server adds the currently issued content to the corresponding authority content list and stores the content in the cache.
Specifically, fig. 4 is a schematic diagram of a method for adding content to a cache according to an embodiment of the present disclosure. As shown in fig. 4, the server obtains basic information of the released content and content right information, and determines the identifier of the current content and content viewing right information corresponding to the release range. The server caches the released content according to the authority content caching strategy, namely, the released content is respectively added to corresponding authority content lists in the cache according to the authority dimensionality corresponding to the released content.
S104, receiving a content viewing request of the user, acquiring an authority content list matched with the authority of the user from the cached authority content list, and determining whether the user is allowed to access corresponding content.
After receiving a content viewing request of a user, the server acquires an authority content list matched with the attribute of the current user from the cached authority content list, compares the identifier of the content requested to be viewed by the current user with the identifier of the content in the determined matched authority content list, and determines whether the identifier of the content requested to be viewed by the current user is in the authority content list matched with the authority of the user, namely determines whether the current content allows the current user to access. The user attribute is determined based on the authority dimension, the exemplary description of the authority dimension in S102 is used, the authority dimension includes a user, an organization, and a role, and the user attribute correspondingly includes user information, organization information, and role information.
And when the server determines that the current user is allowed to access the corresponding content, acquiring basic information of the current content from the database according to the identifier corresponding to the content accessed by the current user in the cache, and returning the basic information to the current user so as to ensure that the user can inquire the content under the condition that the current content allows the user to inquire.
In an embodiment of the present application, if there may be intersections among contents included in the respective rights content lists, the server first determines published contents included in the rights content list that matches the rights of the current user, then merges the published contents in the rights content list that matches the rights of the current user, and deletes repeated published contents in the rights content list after the merging to determine all valid contents that can be viewed by the user, so that data redundancy can be effectively avoided, faster query execution is facilitated, unnecessary time waste is reduced, and system efficiency is improved.
For example, fig. 5 is a schematic diagram of a content query method according to an embodiment of the present application. As shown in fig. 5, the server receives a content viewing request of a user, and determines a rights content list matching the rights of the current user from the cached rights content list according to the specific dimension information of the current user. And meanwhile, the server determines the published contents contained in the authority content list matched with the current user, merges the determined published contents and deletes the identification of the repeatedly appeared published contents.
Specifically, the server first obtains specific dimension information of the user, for example, the specific dimension information in fig. 5 is: user U003, affiliated organization ORG003, affiliated role R001.
Then, according to the specific dimension information of the user, a rights content list that the user has rights is found, for example, the rights content list that the user has rights in fig. 5 is: USER _ U003, ORG _ ORG002, roll _ R001.
Finally, merging the published contents in the authorized content list of the user, and deleting the repeated content identifiers, so as to obtain the authorized content list of the user, for example, the content identifiers in the authorized content list in fig. 5 are 0000001, 0000002, and 0000003.
In an embodiment of the application, after the content is published and when a system administrator or a content owner edits and modifies the content viewing permission information of the published content, the server obtains a modification request of the content viewing permission information, and determines that the system administrator or the content owner modifies the content viewing permission information of the published content when the content viewing permission information is monitored to be modified, so as to obtain the modified content viewing permission information. And the server modifies the published content cached in the authority content list corresponding to the content viewing authority information according to the specific dimension information in the modified content viewing authority information.
In an embodiment of the application, the server compares the original content viewing permission information of the published content with the modified content viewing permission information to obtain the specific dimension information deleted by the modified content viewing permission information and/or the newly added specific dimension information. On one hand, under the condition that the modified content viewing permission information deletes the specific dimension information, the server finds the permission content list corresponding to the deleted specific dimension information according to the specific dimension information deleted by the modified content viewing permission information, and deletes the published content in the permission content list corresponding to the deleted specific dimension information. On the other hand, under the condition that the modified content viewing permission information adds the specific dimension information, the server finds the permission content list corresponding to the newly added specific dimension information according to the newly added specific dimension information of the modified content viewing permission information, and adds the currently issued content to the permission content list corresponding to the newly added specific dimension information. According to the content viewing permission information modification method and device, under the condition that the content viewing permission information is modified, corresponding modification is conducted on the users allowed to view published content, so that the current content is only allowed to be accessed by the users corresponding to the content viewing permission information, and therefore the content viewing safety is guaranteed.
In an embodiment of the application, before the server checks the authority information according to the content corresponding to the release range and the authority dimension information in the content checking authority information, respectively, before constructing an authority content list corresponding to the authority dimension, or before adding the currently released content to an authority content list corresponding to newly added specific dimension information, it is necessary to determine whether an authority content list corresponding to the current authority dimension already exists in the cache, and when it is determined that the authority content list corresponding to the current authority dimension does not exist in the cache, respectively construct the authority content list corresponding to the current authority dimension, thereby ensuring the uniqueness of the authority content list.
In an embodiment of the present application, in addition to sorting according to a certain attribute of the conventional content, for example, sorting according to time, the server may sort the released content after deletion and duplication according to a preset sorting rule, for example, a browsing amount, an attention amount, a collection amount, and the like, so as to serve information requirements of each business system with high quality and improve quality of service.
According to the method and the device, the cache structure corresponding to the authority dimension is arranged, the content is cached according to the user authority, the structure and the order of content caching are enhanced, the relation between the user authority and the content is maintained, the content acquisition capacity of a service system is improved, and the query efficiency is improved; meanwhile, based on the content checking request of the user, the authority content list matched with the user authority is obtained from the cached authority content list, whether the user is allowed to access the corresponding content or not is determined, the efficiency and the safety of content inquiry can be guaranteed, the working efficiency of the user is improved, the time of user inquiry is shortened, and the service quality and the resource utilization rate are improved. In addition, published contents in the permission content list matched with the permission of the user are merged, and repeated contents are deleted, so that data redundancy and waste of storage space are effectively avoided, and the utilization rate of a cache space is improved.
