Description
Technical Field
The present invention relates to the field of computer and software technologies thereof, and in particular, to a method and an apparatus for supporting multi-user editing of data objects at a server.
Background
With the development of internet technology, data edited on one client can be synchronized to other clients of the system through a server. According to the currently commonly used scheme, the client updates the data of the server mainly by means of polling and Comet (a server push technology). The polling mode is mainly to set a specific time interval, the browser sends an interface calling request to the server at each time interval point, and then the server returns the latest data to the browser of the client, so as to achieve the effect that the page can reflect the data change of the server in time. The Comet method mainly utilizes a technology (adopting Comet technology based on ajax long polling) for simulating two-way communication between a client and a server.
Specifically, the process of the client updating data from the server by polling and Comet technology is described in detail below in conjunction with fig. 1 and 2, respectively.
As shown in fig. 1, the updating of data from the server by the client through the polling technique mainly includes the following processes:
a timer (such as 2 seconds) is set in the front-end page JS, and a data request is initiated to the server end in a timing cycle;
the server side returns the page to display the required data according to the service after receiving the request;
if the server does not return data, the client (browser) continues to initiate data requests to the server when the timing time is reached.
As shown in fig. 2, the client updating data from the server through Comet technology mainly includes the following processes:
after the front-end page is loaded, establishing a long HTTP connection (such as connection 1, connection 2 and the like) between the ajax (asynchronous JavaScript and XML) and the server;
if the server side has no data updating, no data is returned, and the current request enters a dormant state;
if the sleep time exceeds the set timeout time, the server will return a blocking request (send a timeout prompt) and close the current connection, and the front-end page will initiate a new request to the server after processing the request and re-establish a new long connection;
if the service end has a service data change event trigger (namely, data update), the service end immediately returns the requested data, then closes the current connection, and after the client finishes processing the returned data, the client re-initiates the request to the service end again and re-establishes a new long connection.
FIG. 3 is a schematic diagram illustrating an implementation process of updating data from a server by a client through Comet technology. As shown in fig. 3, after the connection between the client and the server is established, the server checks whether the service data has changed, if yes, returns data to the client and closes the current connection, and the process is ended, otherwise, the current request enters a sleep state to wait for a data change notification; after the current request enters a sleep state, whether the sleep time of the current request is overtime is checked, if yes, an overtime prompt is returned to the client side and the current connection is closed, and if not, a data change notification is waited until the service data of the server side is changed, data is returned to the client side and the current connection is closed.
The above solutions for updating data from the server by polling and Comet technologies at the client have many disadvantages: first, the polling method is used, so that the transmitted request cannot return changed data every time, which wastes server bandwidth, and continuously requests server resources, thereby increasing server pressure. Secondly, in the scene of editing the table online by multiple people simultaneously in a Comet mode, because the frequency of data synchronization is very high, a connection is newly established when the Comet finishes data response every time, and thus, the Comet mechanism can cause the waste of bandwidth and the increase of server pressure.

Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 4 is a schematic diagram of the main steps of a method for supporting multi-user editing of data objects at a server according to an embodiment of the present invention.

FIG. 5 is a block diagram illustrating an overall framework for supporting multi-user editing of data objects at a server according to an embodiment of the present invention.
The server establishes an editing connection with the client through the data pushing manager, monitors the modification of the client to the data object and pushes the modified data object to all other users except the client in the user group. As shown in fig. 5, the data Push Manager can be implemented by a Push Manager of the Server, where the Push Manager is a distributed cluster service for managing websocket connections developed based on a Netty framework (a programming framework for rapidly developing network clients/servers), and includes two services, namely, a Push Server (Push Server) and a Push Client (Push Client). The Push Server is used for allocating connection between the Client and the Push Client, and in order to balance load, the Push Server generally allocates the Push Client with the least number of Client connections, and the Push Client is responsible for establishing editing connection with the Client. The Push Client is used for establishing connection between the clients and pushing the data object to the clients. The data objects in fig. 5 are exemplified by data tables, and the data push manager saves the connection ID of the client, the user information of the client, and the edit connection information of other users in the user group to a storage system, such as a Redis storage system, through a corresponding table service.
According to the general framework shown in fig. 5 for supporting multi-user editing of a data object at a server, a specific implementation flow of supporting multi-user editing of a data object at a server according to an embodiment of the present invention is shown in fig. 6, and specifically includes the following steps S601 to S615.
Step S601: the server receives a request for editing the data table from the client.
Wherein the form can be created by the client or other clients, and the creator of the form adds all client users who can use the form to a user group when creating the form, and only the users in the user group have the right to edit the form.
Step S602: the server side verifies whether the client side has the authority of editing the table, if so, the step S603 is executed, otherwise, the step S604 is executed.
The authority of the client is verified mainly to ensure data security and prevent illegal users who are not in a user group from editing and modifying data in the form.
Step S603: and the client requests to establish an editing connection to a data push manager of the server.
After the step S603 is executed, a step S605 is executed.
Step S604: the client is denied an edit request to the data form.
Step S605: and judging whether the connection is successfully established, if not, executing the step S606, and if so, executing the step S609.
Step S606: the establishment of the edit connection is retried and the next step S607 is executed.
Step S607: and judging whether the retry operation is successful, if so, executing step 609, otherwise, executing step 608.
Step S608: and the server side returns a prompt message of connection failure to the client side.
Step S609: the data push manager processes the connection request of the client and stores the connection ID and the user information of the client in the storage system.
Specifically, after receiving a connection request of a Client, the data Push manager is processed by a Push Server (Push Server), the Push Server obtains the sum of the Client connection number of each Push Client (Push Client), and finds out the Push Client with the least Client connection number through comparison, so that the Push Client is responsible for establishing an editing connection with the Client, and thus, the load balance of the clients connected to the Push clients can be ensured. Then, the pushServer sends the connection ID, the user information and the like of the Push Client and the Client to the corresponding table service, the table service adds the connection ID and the user information to the user group and stores the user group in a storage system (such as Redis), and finally the connection information such as the connection ID, the user information and the like is returned to the Client so that the Client can establish connection with the Push Client according to the connection information.
The user group also includes the edit connection information (including connection ID and user information) of other users in the group, and when these users establish edit connection with the server, the table service will store these information in the storage system, when some user exits the table edit function, the corresponding edit connection of this user will be closed, and the edit connection information of this user will be moved out of this user group at the same time.
Step S610: and the client side edits the data form and submits the edited data to the corresponding form service of the server side when the condition of the data modification pushing condition set is reached.
The conditions in the data modification and pushing condition set are preset by a client user according to requirements, and specifically include the following conditions: the modification data exceeds 3 characters, and the modification time exceeds 3 seconds.
Step S611: the form service of the server notifies the data push manager to perform data push.
Step S612: the data push manager pushes data to all other users in the user group except the client.
Step S613: the server determines whether the data pushing is successful, if so, executes step S614, otherwise, executes step S615.
Step S614: and other users receiving the data update the data according to the pushed data.
Step S615: and the data pushing manager retries the data pushing, and if the data pushing fails to retry, returns a prompt message of the pushing failure to the client.
If the retry fails, the client can notify other users to update the data in the table through offline after receiving the prompt message of push failure returned by the server.
When the Client exits the form editing function, the data Push manager closes the Push Client's editing connection with the Client, and the form service removes the Client's connection ID and user information from the user group.
The technical scheme of the embodiment of the invention is based on the characteristics of high performance and high reliability of Netty, and the data Push Manager (Push Manager) for managing the websocket connection is developed, so that the client and the server can constantly keep a data communication pipeline, and when the server has the change of service data (such as table data), the server can actively, timely and reliably send the latest data to the client.
