Description

Multi-terminal data synchronization method, device, equipment and medium

Technical Field

The present disclosure relates to internet technologies, and in particular, to a method, an apparatus, a device, and a medium for synchronizing multi-terminal data.

Background

When a user logs in a same application at multiple terminals by using the same account, the data of the application needs to be synchronized at each terminal. For example, a user has 3 mobile phones (or different terminals such as mobile phones, tablet computers, desktop computers, and the like), and all three mobile phones have one and the same shopping application a, and when the user adds a commodity in a shopping cart of the shopping application a of one of the mobile phones, the user wants to continue browsing the commodity or pay for the added commodity by using the shopping applications a of the other two mobile phones, it is necessary to synchronize the commodity data of the shopping cart in the shopping applications a of the three mobile phones.

In the prior art, the data synchronization of multiple terminals is realized through the following processes: when the application in any one of the terminals has data update, the server side of the application records the update state of the account application, and when a user logs in the same application of other terminals by using the same account, the applications of other terminals actively request the server to update the current data of the account, so that the data synchronization of the same application logging in different terminals by using the same account is realized.

However, in the above implementation process of data synchronization of multiple terminals, after the user opens corresponding applications in different terminals, the user needs to actively update and synchronize data, and such data synchronization cannot be performed in real time, which is not convenient.

Example one

Fig. 1 is a flowchart illustrating a multi-terminal data synchronization method applied to a server according to an embodiment of the present disclosure, where the embodiment of the present disclosure is applicable to a case where a client account implements real-time synchronous update of multiple terminal client data when multiple terminals log in, and the method may be implemented by a multi-terminal data synchronization apparatus configured in the server, and may be implemented by software and/or hardware in a server device.

As shown in fig. 1, the multi-terminal data synchronization method applied to a server provided in the embodiment of the present disclosure includes the following steps:

s110, when detecting that the data updating occurs in the client of the current terminal, determining whether the account of the client is logged in at least one other terminal.

Specifically, after any client of one terminal logs in through a registered account, the server acquires the device identifier, such as a device serial number, of the terminal logging in the account.

The current terminal is the terminal with the data update of the client, other terminals are the terminals with the same account and the other terminals do not have the data update. Illustratively, there is a user who logs in a shopping application simultaneously on a mobile phone, a tablet computer and a desktop computer (or different mobile phone terminals and other terminals with different device identifiers) by using the same account. When a user adds a shopping cart to a commodity or collects a commodity in the shopping application through the mobile phone, the shopping application on the mobile phone generates data updating, and then the mobile phone is the current terminal. When detecting that the data of the current terminal is updated, the server determines whether the account of the shopping application is logged in other terminals, wherein the tablet computer and the desktop computer belong to other terminals.

S120, responding to a determination result that at least one other terminal logs in the account of the client, and sending a data updating instruction to all terminals logging in the account so as to enable the client of the at least one other terminal to synchronously complete data updating, wherein the data updating instruction comprises data to be updated and an updating sequence value, and the updating sequence value is used for representing the number of times of client data updating operation recorded by the server.

The update sequence value is used for representing the number of times of the client data update operation, and is all data update operations of the client account on different terminals recorded by the server, for example, when a client account has data update operations in a mobile phone, a tablet computer and a desktop computer, the server can sequentially record and accumulate the number of times of the client data update operations according to the sequence of the update operations. In each terminal, there is also a corresponding update order value, which records the number of update operations that the client has completed on the terminal where the client is located. For example, assuming that initial values of update sequence values recorded on a server and terminals logging in the same account are all 0, when a data update operation is applied to shopping at a mobile phone terminal, the update sequence value of the mobile phone terminal becomes 1, after detecting that a client of a current terminal has data update and before sending a data update instruction to all terminals logging in the account, the server obtains the update sequence value set for the client, and increments the update sequence value by one, that is, the update sequence value of the server is updated from 0 to 1. When the shopping application of the tablet computer is subjected to data updating operation once, the updating sequence value of the terminal of the tablet computer is changed into 1, correspondingly, when the server detects the data updating operation of the tablet computer, the updating sequence value of the server is updated from 1 to 2, and when other terminals logging in the same account are subjected to data updating operation, the updating sequence value of the server is updated in the same mode.

It should be noted here that the server sends a data update instruction to all terminals registered with the account, that is, the current terminal that has performed data update also receives the data update instruction. In this way, the server side is considered to have a large data volume to be processed, and when the same client side of a plurality of terminals logs in the same account and the plurality of terminals simultaneously perform different data updating operations, one terminal is easily missed to synchronize one data updating operation. And sending a data updating instruction to all terminals logged in with the account by the server, so that all the terminals logged in with the account can synchronize all the data updating steps.

Further, in order to avoid that the current terminal repeatedly executes the data updating operation after receiving the data updating instruction, the data to be updated includes the identifier of the current terminal, that is, the identifier of the terminal where the client implementing the data updating operation is located, such as the identifier of the mobile phone terminal in the above example, so that the terminal receiving the data updating instruction determines whether to execute the current data updating operation. For example, the server sends the data updating instruction to the mobile phone, the tablet computer and the desktop computer terminal at the same time, and the mobile phone terminal recognizes that the current terminal identifier in the data to be updated is the terminal identifier of the mobile phone terminal, which indicates that the data to be updated is updated at the mobile phone terminal, and does not need to execute the data updating instruction again.

Preferably, the data update instruction further includes a data update type identifier, so that after the client obtains the data update instruction of the data update operation for multiple times, if multiple data update type identifiers of the same type exist, the data update is completed according to the latest data to be updated in the data to be updated corresponding to the multiple data update type identifiers of the same type, and thus the data update efficiency of the client can be improved. For example, when a user adds a commodity into a shopping cart and then deletes the commodity in the shopping cart through a mobile phone terminal in a shopping application, and repeats the process for multiple times, and finally adds the commodity into the shopping cart, the tablet personal computer terminal may acquire multiple data update instructions, and then may determine whether the data update operation in the latest data update instruction is to add the commodity into the shopping cart or delete the commodity from the shopping cart according to the data update type identifier in the tree update instruction, and perform an update operation once without repeatedly performing an intermediate process of deleting the commodity in the shopping cart after adding the commodity into the shopping cart.

The embodiment of the disclosure provides a multi-terminal data synchronization method applied to a server, which determines whether a client account logs in other terminals or not when the server detects that a client of a current terminal has data update, and sends a data update instruction to other terminals logging in the client account, wherein the data update instruction comprises data to be updated and an update sequence value, so that a plurality of terminals logging in one client account at the same time realize synchronous data update, the problem that the data update synchronization is actively performed at different terminals, and the plurality of terminals logging in one client account at the same time cannot synchronously update in real time is solved, when any one of the plurality of terminals logging in one client account at the same time has data update, the same applications of other terminals can automatically complete data synchronization in real time and only synchronize data with change, all data do not need to be traversed, the synchronization efficiency is improved, a user does not need to actively pull updated data, and the user experience is improved.

Example two

Fig. 2 is a flowchart illustrating a multi-terminal data synchronization method applied to a client according to a second embodiment of the present disclosure, where the second embodiment of the present disclosure is applicable to a case where a client account implements real-time synchronous update of multiple terminal client data when multiple terminals log in, and the method may be implemented by a multi-terminal data synchronization apparatus configured in a terminal device, and may be implemented by software and/or hardware in the terminal device.

Fig. 2 shows a flowchart of a multi-terminal data synchronization method applied to a client according to a second embodiment of the present disclosure, where the multi-terminal data synchronization method provided in the embodiment of the present disclosure includes the following steps:

s210, receiving a data updating instruction sent by a server, wherein the data updating instruction comprises data to be updated and an updating sequence value, and the updating sequence value is used for representing the number of times of client data updating operation recorded by the server.

Specifically, when the server detects that a client with a terminal has data update and determines that an account of the client is already logged in at least one other terminal, the server sends a data update instruction to all terminals logged in with the account. Then, the terminal that receives the data update instruction issued by the server is the terminal that logs in the same account at the same time. The terminals include a terminal where a data update operation occurs and a terminal to be updated synchronously.

Preferably, the data to be updated includes an identifier of a terminal where the client that implements the data update is located. For example, a user logs in a shopping application simultaneously with the same account on a mobile phone, a tablet computer and a desktop computer (or different mobile phone terminals and other terminals with different device identifiers). When a user adds a shopping cart to a commodity or collects a commodity in the shopping application through a mobile phone, the shopping application on the mobile phone generates data updating, and then the identifier of the mobile phone terminal is the identifier of the terminal where the client side for realizing the data updating is located, so that the terminal receiving the data updating instruction judges whether to execute the current data updating operation. For example, the server sends the data updating instruction to the mobile phone, the tablet computer and the desktop computer terminal at the same time, and the mobile phone terminal recognizes that the identifier of the terminal where the client implementing the data updating is located is the terminal identifier of the mobile phone terminal, which indicates that the data to be updated is updated at the mobile phone terminal, and does not need to execute the data updating instruction again.

Further, the update sequence value is used to indicate the number of times of the data update operation of the client, and is all data update operations of the client account recorded by the server on different terminals, for example, when a data update operation of a client account exists in a mobile phone, a tablet computer, and a desktop computer, the server may sequentially record and accumulate the number of times of the data update operation of the client according to the sequence of the update operations.

S220, judging whether the update sequence value is smaller than or equal to a numerical value obtained by adding one to the current update sequence value of the client at the current terminal where the client is located.

And the current updating sequence value is the number of times of updating operation finished by the client on the current terminal recorded by each terminal. For example, assuming that initial values of update sequence values recorded on the server and each terminal logged in the same account are all 0, when a shopping application at the mobile phone end has a data update operation, the update sequence value of the mobile phone terminal becomes 1, and the current update sequence value of the mobile phone terminal is 1.

Assuming that the current update sequence value of the current terminal is 1, and the update sequence value in the data update instruction received by the current terminal is 2, if 1 plus 1 is exactly equal to 2, it indicates that the data update instruction received by the current terminal is exactly the further data update operation that the current terminal needs to execute, so as to implement synchronous update of the client data in the current terminal.

In an embodiment, assuming that two terminals a and B logged in the same account perform data updating operations at the same time, and the current updating sequence values of the two terminals are both 1, when the server detects the data updating operations of the two terminals at the same time, it is not certain which terminal corresponds to the updating sequence value of the data updating operation as 1, and which terminal corresponds to the data updating operation as 2. Then, the data update instruction with the update order of 1 received by the terminal a may correspond to the data update operation already completed by the terminal a itself, or may correspond to the data update operation completed in the terminal B, and at this time, the current update order value of the terminal a plus 1 is greater than the update order value in the received data update instruction. Therefore, the terminal a needs to further determine whether to perform the data updating operation according to the information such as the data to be updated in the data updating command.

And S230, responding to a judgment result that the update sequence value is less than or equal to a numerical value obtained by adding one to the current update sequence value of the client at the current terminal where the client is located, and finishing data update according to the data update instruction.

Specifically, the current terminal judges whether the identifier belongs to the identifier of the current terminal; if yes, ignoring the received data updating instruction and not executing the data updating. Otherwise, finishing data updating according to the data updating instruction, and adding one to the current updating sequence value.

In an embodiment, if one of the terminals logged in the same account is disconnected from the server due to a network problem, etc., then when the terminal is reconnected to the server and receives a data update command issued by the server, the update sequence value in the data update command may not be equal to the value of the current update sequence value of the terminal plus 1, and the difference between the update sequence value in the data update command and the value of the current update sequence value of the terminal plus 1 is greater than 1. For example, if the current update order of the current terminal is 1 and the update order of the received data update instruction is 7, it indicates that the terminal has 6 times of data update operations that are not synchronized, it needs to request the server for the data update instruction corresponding to the data update operation with the unexecuted update order of 2-6, and then complete the corresponding data update according to all the unexecuted data update instructions. And then, updating the current updating sequence value of the current terminal to the updating sequence value, namely updating 1 to 7.

Preferably, the data update instruction further includes a data update type identifier, and correspondingly, when a plurality of data update type identifiers of the same type exist in the data update instruction corresponding to the plurality of unexecuted update order values, the method further includes: determining the latest data to be updated in the data to be updated corresponding to the data updating type identification of each same type; and finishing the data updating operation corresponding to the plurality of data updating type identifications of the same type according to the latest data to be updated. For example, assuming that the data update operation is an increase of the praise of a certain picture, if the data update type identifier in the data update instruction corresponding to the plurality of unexecuted update sequence values all increases the praise by one, the latest praise may be determined according to the latest data update operation instruction without increasing the praise to the latest value one by one.

The second embodiment of the disclosure provides a multi-terminal data synchronization method applied to a client, which implements data update synchronized with other terminals logging in the same client account by receiving a data update instruction sent by a server, and according to data to be updated and an update sequence value in the data update instruction, solves the problem that a user needs to actively update and synchronize data at different terminals, and a plurality of terminals logging in one client account at the same time cannot synchronously update in real time, and implements that when a client in any one of the plurality of terminals logging in one client account at the same time has data update, the same applications of other terminals can automatically complete data synchronization in real time, and only data with change is synchronized, without traversing all data, improving synchronization efficiency, and without the user actively pulling updated data, the user experience is improved.
