Description
Technical Field
The invention belongs to the technical field of computers, and particularly relates to a cross-domain user data synchronization method based on a subscription and sending mode.
Background
In recent years, various message middleware based on data subscription and publishing modes have been widely applied to various information systems for processing message transceiving inside application systems. Message middleware is a supportive software system that provides asynchronous or synchronous, reliable message transfer in a network environment based on queue and messaging technology.
In a specific network environment, a set of user management services is deployed in each region and used for providing services with functions of user information, role information, authority information, login authentication and the like in the region. Between each region, that is, in a cross-domain scenario, in a specific network environment, only a specific port or ports are allowed to be opened for data interaction due to security considerations, and a common HTTP request cannot perform service access in the cross-domain scenario. Therefore, existing message middleware is not applicable to this particular network environment with security restrictions. At present, a scheme for implementing cross-domain user data synchronization is to export user data into an offline file, send the offline user data file to a target domain through manual or software capable of implementing cross-domain file transmission, and import user data of a source domain into user services in the target domain in a manner of importing the offline user data file. Although the scheme can realize the synchronization of cross-domain user data, the unified configuration management cannot be formed on the universal user data, the operation is complicated, and the cross-domain user data synchronization is difficult.

Further, the step S6 includes:
(1) the subscription node updates or deletes corresponding user data, the global unique identification ID of the updated or deleted user data in the subscription node traverses in the order sending, and after matching, a new thread is started to execute sending of an update or deletion data message to the sending node;
(2) and adding the user data in the subscription node, and if the sending node needs to pull the added user data, repeating the steps from S2 to S5 to perform subscription operation.
Further, in step S6, if the piece of user data information in the subscribing node is updated, after the update is successful, the record in the sending order is scanned according to the global unique identifier of the piece of data, the related data is sent to the user management service of the sending node or other sending nodes subscribing to the record through the node information recorded in the order, and the operation type of the piece of data is identified as the update operation.
Further, in step S6, after receiving the update or delete data message from the subscribing node, the sending node updates the updated user data into the local node or deletes the corresponding user data in the local node, and after completing, sends a receipt message to the subscribing node to confirm that the update or delete is completed.
Further, in step S6, if the subscribing node receives the update or delete completion confirmation message sent by the sending node, the update or delete operation is completed, otherwise, the subscribing node will resend the update or delete data message to the sending node; if the data updating or deleting is not successful for more than two times, the data is marked as a pushing failure record, and the user can manually update or delete the data.
Further, in step S6, if a certain piece of user data is newly added in the subscribing node, if the sending node needs to pull the piece of newly added user data, the subscribing operation needs to be performed again in the subscribing node.
Further, in step S6, when the user management service of the sending node no longer needs the previously subscribed user data, the user data that needs to be unsubscribed is selected from the sending node, and after the unsubscribing operation is performed, the relevant user data in the sending node is no longer retained, the subscription order related to the sending node is deleted, and the unsubscribing information is sent to the subscribing node, and the subscribing node also deletes the relevant sending order.
Further, the user in the node only has an operation right, namely an owner operation right, on the user data of the node.
Has the advantages that: in a network environment with security restrictions, the nodes can only communicate with each other through designated transmission software, which restricts normal communication between the nodes, and user data between the nodes cannot be summarized and synchronized through ordinary HTTP and other methods. Therefore, the invention provides a user data synchronization mode based on a subscription sending mode, and realizes the synchronization of cross-domain user data among nodes by using transmission software as a communication means through user management service. In addition, the user data synchronization based on the subscription and sending mode can be decoupled from the user service business to the maximum extent, and the subscription and sending functions are carried out through a newly started thread, so that the flow processing of the normal business in the node is not influenced. The user data synchronization based on the subscription and sending mode can effectively utilize bandwidth resources, and perform the functions of subscription and sending as required and synchronous pushing on the user data. Finally, the user data authority of the home modification can effectively avoid modification conflict of the user data and can protect the safety of the user data.
