[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0047] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0048] In order to quickly and accurately find the target identification information, an embodiment of the present application provides an identification resolution method, in which the server in the local node searches for the target identification information from the local cache database based on the received identification resolution request. If the target identification information is not found, an identification resolution request is sent to the target node in the distributed storage architecture, so that the target node searches for the target identification information. If the target node finds the target identification information, the result of the successful search and the resolution information corresponding to the target identification information are returned to the server of the local node, and the resolution information is displayed through the client, thereby realizing fast and accurate search for the resolution information corresponding to the target identification information.

[0049] The following is a detailed explanation of an identification resolution method provided in an embodiment of the present application through specific examples in conjunction with the accompanying drawings. Figure 1 One of the flowcharts of an identification resolution method provided in an embodiment of the present application; Figure 1 As shown, the method includes:

[0050] S101: Receive an identity resolution request sent by a client.

[0051] S102: According to the identity resolution request, search for target identity information from a local cache database.

[0052] In this embodiment, the user enters the identification information to be queried in the input box of the preset identification input interface on the client, and clicks the query control to send an identification resolution request to the server, so that the server can receive the identification resolution request sent by the client, and the identification resolution request includes the identification information to be queried.

[0053] A large amount of identification information and resolution information corresponding to the identification information are pre-stored in the local cache database. For example, if the identification information is A, the resolution information corresponding to the identification information A includes identity information, registration information, address information, and the like.

[0054] The server searches for the target identification information from the local cache database based on the identification resolution request. If identification information is found in the local cache database that is consistent with the identification information to be queried, the server determines that the identification information is the target identification information, and determines the resolution information corresponding to the target identification information. The server returns the resolution information corresponding to the target identification information to the client, so that the client displays the resolution information corresponding to the target identification information on the preset identification input interface.

[0055] It should be noted that when the server receives the identity resolution request sent by the client, it is also necessary to verify the user identity of the client based on the role-based access control (RBAC) mechanism to determine whether the user identity is authorized. If the verification is successful, the target identity information is searched from the local cache database according to the identity resolution request. If the verification fails, the target identity information cannot be found, so that the user can only access the identity information within his authority to prevent unauthorized access and data leakage.

[0056] S103: If the target identification information is not found in the local cache database, send an identification resolution request to the target node, so that the target node searches for the target identification information from the target node cache database according to the identification resolution request, and returns the search result to the server of the local node.

[0057] The target node is a node at another level in the distributed storage architecture except the local node.

[0058] Specifically, if the server of the local node does not find identification information consistent with the identification information to be queried in the local cache database, the target node is determined in the distributed storage architecture, and an identification resolution request is sent to the target node, so that the target node searches for the target identification information from the target node cache database based on the identification information to be queried in the identification resolution request.

[0059] If the server of the target node finds that the identification information is consistent with the identification information to be queried in the target node cache database, the identification information is determined to be the target identification information, and the resolution information corresponding to the target identification information is determined, and the search result is returned to the server of the local node. If the search result is successful, the search result also includes the resolution information corresponding to the target identification information.

[0060] The local node and the target node are nodes in the pre-built distributed storage architecture. The target node is the parent node of the local node, which can be the parent node, or the parent node of the next level, without limitation. For example, if the local node is an enterprise-level node, the target node can be a municipal-level node, a provincial-level node, etc.

[0061] Optionally, if the target node fails to find the target identification information from the target node cache database, the target node sends an identification resolution request to the superior node, so that the superior node searches for the target identification information from the superior node cache database according to the identification resolution request, and returns the search result to the target node's server.

[0062] Specifically, if the target node fails to find the target identification information in the target node cache database, the target node's parent node is determined in the distributed storage architecture, and the target node sends an identification resolution request to the parent node, so that the parent node searches for the target identification information from the parent node cache database based on the identification information to be queried in the identification resolution request.

[0063] If the server of the upper-level node finds that the identification information is consistent with the identification information to be queried in the cache database of the upper-level node, the identification information is determined to be the target identification information, and the resolution information corresponding to the target identification information is determined, and the search result is returned to the server of the target node. If the search result is successful, the search result also includes the resolution information corresponding to the target identification information. At this time, the target node returns the resolution information corresponding to the target identification information to the server of the local node.

[0064] It should be noted that if the superior node also fails to find the target identification information, it will continue to send identification resolution requests to the superior node until the target identification information is found by the target superior node, and return the resolution information of the target identification information in turn. If no node in the distributed storage architecture can find the target identification information, the search result returned to the server of the local node is a search failure.

[0065] S104: If the search result indicates that the search is successful, obtain the resolution information corresponding to the target identification information and send it to the client, so that the client displays the resolution information.

[0066] Specifically, the server of the local node sends the parsing information corresponding to the target identification information to the client, so that the client displays the parsing information corresponding to the target identification information on the preset identification input interface.

[0067] It should be noted that, when the local node sends an identification resolution request to the target node, and when the target node returns the search result to the local node, the queried identification information and the resolution information are encrypted through an encryption protocol to ensure the security and integrity of the information during transmission. The encryption protocol can be Secure Socket Layer (SSL), Transport Layer Security (TLS), etc.

[0068] In addition, the server of the local node also records all access and modification operations of identification information for security auditing, and monitors in real time whether there are security threats in the process of identification information query, and regularly backs up identification information to ensure rapid recovery when data is lost or damaged.

[0069] In summary, an embodiment of the present application provides an identification resolution method, which includes: receiving an identification resolution request sent by a client, searching for target identification information from a local cache database according to the identification resolution request, and if the target identification information is not found in the local cache database, sending an identification resolution request to a target node, so that the target node searches for the target identification information from the target node cache database according to the identification resolution request, and returns the search result to the server of the local node; the target node is a node at another level in a distributed storage architecture except the local node; if the search result indicates that the search is successful, obtaining resolution information corresponding to the target identification information and sending it to the client, so that the client displays the resolution information. In the method of the present application, the target identification information is first searched for by the server of the local node. If not found, an identification resolution request is sent to the target node, so that the server of the target node searches for the target identification information until the target identification information is found, and the resolution information corresponding to the target identification information is returned to the server of the local node. By means of multiple iterative searches, the resolution information corresponding to the target identification information can be found quickly and accurately. In addition, if the local cache database is not found, the target node cache database is searched, which can effectively reduce the number of direct visits to the storage node and improve query efficiency.

[0070] The present application also provides another possible implementation of the identification resolution method. Figure 2 A second flow chart of an identification resolution method provided in an embodiment of the present application is as follows: Figure 2 As shown, if the target identification information is not found in the local cache database, an identification resolution request is sent to the target node, including:

[0071] S201. Obtain the identification code to be queried according to the identification resolution request.

[0072] S202: Search the target identification information from the local cache database according to the identification code to be queried. If the target identification information matching the identification code to be queried is not found, send an identification resolution request to the target node.

[0073] Optionally, the identity resolution request includes: an identity code to be queried.

[0074] In this embodiment, if the user enters the identification information to be queried as the identification code to be queried in the input box of the preset identification input interface on the client, the identification resolution request sent to the server includes the identification code to be queried, and the server reads the identification code to be queried from the identification resolution request, wherein the identification code to be queried includes fields, field values, area information, etc.

[0075] The server of the local node searches for the target identification information from the local cache database according to the identification code to be queried. If identification information is found in the local cache database that is consistent with the identification code to be queried, the identification information is determined to be the target identification information, and the resolution information corresponding to the target identification information is determined, and the resolution information corresponding to the target identification information is returned to the client.

[0076] In the method provided in the embodiment of the present application, according to the identification resolution request, the identification code to be queried is obtained, and according to the identification code to be queried, the target identification information is searched from the local cache database. If the target identification information matching the identification code to be queried is not found, an identification resolution request is sent to the target node, so that the target identification information is determined by searching for the identification information matching the identification code to be queried.

[0077] The present application also provides another possible implementation of the identification resolution method. Figure 3 A flowchart of a method for resolving an identifier provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, according to the identity resolution request, the target identity information is searched from the local cache database, including:

[0078] S301. Obtain registration time according to the identity resolution request.

[0079] S302: Search the target identification information from the local cache database according to the registration time, and determine the identification information that meets the registration time as the target identification information.

[0080] In this embodiment, if the user enters the registration time as the identification information to be queried in the input box of the preset identification input interface on the client, the registration time is included in the identification resolution request sent to the server. The server of the local node searches for the target identification information from the local cache database according to the registration time, and determines that the identification information that meets the registration time is the target identification information, and returns the target identification information to the client, and displays the target identification information through the client, wherein the number of identification information that meets the registration time as the target identification information can be multiple.

[0081] Optionally, if the identity resolution request includes: registration time, obtain the query identity code corresponding to the registration time according to the registration time.

[0082] Specifically, if the server searches for the target identification information from the local cache database according to the registration time and determines that the resolution information corresponding to the target identification information that meets the registration time does not meet the requirements, the identification code to be queried corresponding to the registration time is determined from the resolution information corresponding to the target identification information.

[0083] In the method provided in the embodiment of the present application, the registration time is obtained according to the identification resolution request, the target identification information is searched from the local cache database according to the registration time, and the identification information that meets the registration time is determined as the target identification information, thereby determining the target identification information by searching for the identification information that meets the registration time.

[0084] The present application also provides another possible implementation of the identification resolution method. Figure 4 A fourth flowchart of an identification resolution method provided in an embodiment of the present application is as follows: Figure 4 As shown, if the target identification information is not found in the local cache database, an identification resolution request is sent to the target node, including:

[0085] S401: Determine a node distance value according to the area information of the identification code to be queried and the area information of the local node.

[0086] S402: Determine a target node according to the node distance value and the area information of the local node, and send an identity resolution request to the target node.

[0087] In this embodiment, the identification code to be queried includes region information. Based on the bidirectional search algorithm of node distance, the absolute value of the difference between the region information of the identification code to be queried and the region information of the local node is calculated, and the calculated absolute value is determined to be the node distance value.

[0088] Since both the local node and the target node belong to the distributed storage architecture, each node has area information. The target area information can be determined based on the node distance value and the area information of the local node, and the target node can be determined based on the target area information, so that the server of the local node sends an identification resolution request to the target node.

[0089] In the method provided by the implementation of the present application, the node distance value is determined based on the area information of the identifier to be queried and the area information of the local node; the target node is determined based on the node distance value and the area information of the local node, and an identifier resolution request is sent to the target node, thereby accurately determining the target node based on the area information of the identifier to be queried and the area information of the local node.

[0090] The present application also provides another possible implementation of the identification resolution method. Figure 5 A fifth flow chart of an identification resolution method provided in an embodiment of the present application is as follows: Figure 5 As shown, before searching the target identification information from the local cache database according to the identification resolution request, the method also includes:

[0091] S501. Build a distributed storage architecture.

[0092] The distributed storage architecture includes multiple levels of nodes, wherein the multiple levels of nodes include local nodes.

[0093] S502: Store multiple identification information in cache databases of multiple nodes in a distributed storage architecture.

[0094] S503: Cluster multiple nodes according to content attributes in the identification information.

[0095] In this embodiment, a distributed storage architecture is constructed in advance based on the node attributes of the local node and the node attributes of the target node. The nodes of the distributed storage architecture can be divided into multiple levels, where content attributes may include: region, level, area, etc., but are not limited to this and can be determined according to the division needs.

[0096] For example, nodes with provincial attributes are at the first level, nodes with municipal attributes are at the second level, and nodes with enterprise attributes are at the third level. Multiple nodes are associated based on node attributes, and the target nodes are nodes at other levels in the distributed storage architecture except for local nodes. For example, the target nodes can be provincial nodes at the first level and municipal nodes at the second level.

[0097] According to the storage performance and capacity requirements of each node, multiple identification information is stored in the cache database of multiple nodes in the distributed storage architecture. For example, the cache database of multiple nodes may include a local cache database of a third-layer local node, which is used to store recently accessed identification information to improve query efficiency, a regional cache database of a second-layer municipal node, which is used to cache frequently accessed identification information in the region, and a global cache database of a third-layer provincial node, which is used to cache the most frequently accessed identification information in the entire system to reduce the burden on storage nodes.

[0098] According to the content attributes in the identification information, the nodes storing the identification information with the same content attributes are clustered to facilitate the search of the target identification information.

[0099] In the method provided in the embodiment of the present application, a distributed storage architecture is constructed, and the distributed storage architecture includes nodes at multiple levels, wherein the nodes at multiple levels include local nodes; multiple identification information is stored in a cache database of multiple nodes in the distributed storage architecture; multiple nodes are clustered according to content attributes in the identification information to achieve multi-level caching of multiple identification information, which helps to improve the efficiency of searching for target identification information.
