Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a data synchronization method for instant messaging according to an exemplary embodiment, which may be applied to a server, as shown in fig. 1. The data synchronization method of instant messaging can comprise the following steps.
In step S11, the session group corresponding to the target account is acquired.
In an embodiment of the present disclosure, the target account may be an account of an instant messaging application, and the subsequently determined target session data to be synchronized, that is, session data generated by the target account interacting with other accounts by logging in the instant messaging application. The server stores session groups of a plurality of accounts. The session groups of each account may be distinguished by the account identification of the respective account. .
In the embodiment of the present disclosure, the server further stores a session list of a plurality of accounts, and the session list of each account stores session data of each account. The session group in the server contains a mapping list, which may point to a list of sessions for each account.
In step S12, among the session groups, the target session group and the target mapping list in the target session group are determined.
In the embodiment of the present disclosure, the session group corresponding to the target account may include a plurality of session groups, but not all the session groups corresponding to the target account are session groups required for this data synchronization, and therefore, it is necessary to identify a target session group required for this data synchronization from among the plurality of session groups corresponding to the target account. The target session group is a changed session group or the target session group is an entire session group. Similarly, the target session group includes a plurality of mapping lists, and not all mapping lists in the target session group are necessarily mapping lists required for this data synchronization, so that the target mapping list required for this data synchronization needs to be determined in the target session group.
In step S13, target session data to be synchronized in the session list is determined according to the target mapping list.
In the embodiment of the present disclosure, because the mapping list is used to point to the session list corresponding to the target account, the target mapping list required by the data synchronization this time is pointed to, and the session data stored in the session list pointed to is the target session data required by the data synchronization this time.
In step S14, the target session data is transmitted to the terminal corresponding to the target account.
In the embodiment of the disclosure, the server determines the target session data required by the data synchronization from the large amount of session data stored this time, and transmits the target session data to the terminal corresponding to the target account, thereby implementing the function of synchronizing the session data from the server to the terminal.
The data synchronization scheme of instant messaging provided by the embodiment of the disclosure is applied to a server. And acquiring a session group corresponding to the target account, wherein the session group comprises a mapping list, the mapping list is used for pointing to a session list corresponding to the target account, and session data are stored in the session list. In the session group, a target session group and a target mapping list in the target session group are determined. The target session group is a changed session group or the target session group is an entire session group. And then, determining target session data to be synchronized in the session list according to the target mapping list, and further transmitting the target session data to a terminal corresponding to the target account.
The server of the embodiment of the disclosure stores session data and session packets of instant messaging. The session packet contains a mapping list for determining session data, and the mapping list can point to a session list storing the session data. Therefore, the server may obtain the session group corresponding to the target account, and then determine which session groups include the mapping list required for this synchronization in the session group, that is, may determine the target session group from a plurality of session groups, and determine the target mapping list from a plurality of mapping lists in the target session group. After the target mapping list is determined, target session data to be synchronized can be determined according to the session list pointed by the target mapping list, and finally, the target session data are transmitted to the terminal, so that the session data of instant messaging are completed and synchronized to the terminal from the server. According to the embodiment of the disclosure, the server determines the target session data to be synchronized in the session list according to the mapping list in the session group, and transmits the target session data to the terminal at one time, so that the session data to be synchronized is prevented from being determined and transmitted by the server for multiple times, the occupation of system resources of the server is reduced, the processing pressure of the server is relieved, and network resources between the terminal and the server are saved.
The embodiment of the present disclosure may synchronize session data from a server to a terminal, and may include two data synchronization schemes, where in the first scheme, the terminal sends a data request to the server, and the server transmits target session data to the terminal according to the data request. And in the second scheme, the server actively transmits the target session data to the terminal. In the following, the two schemes described above will be described in detail.
In an exemplary embodiment of the present disclosure, for the first solution, before acquiring a session group corresponding to a target account, a server receives a data request sent by a terminal, where the data request includes the target account. That is, the server may also receive the target account when receiving the data request from the terminal. The data request indicates that the terminal desires to synchronize the session data from the server, and the target account in the data request indicates an account corresponding to the session data to be synchronized. The server receives the data request containing the target account from the terminal, can obtain the session group corresponding to the target account in a targeted manner, finally determines the target session data to be synchronized, and returns the target session data to the terminal. According to the embodiment of the invention, the data request is sent by the terminal, and the server receives the data request, so that the server can pertinently transmit the target session data to the terminal, and when the server receives the data request, the target session data to be synchronized is determined, thereby avoiding the server from frequently and actively determining the target session data to be synchronized of different accounts, reducing the resource occupation of the server, and reducing the operation pressure of the server.
In an exemplary embodiment of the present disclosure, the data request sent by the terminal includes a synchronization identifier in addition to the target account. The session packet also contains the setup time of the mapping list. In the session grouping, when the target session grouping and a target mapping list in the target session grouping are determined, when the synchronous identifier is a time identifier, determining the changed session grouping after the time represented by the time identifier as the target session grouping, wherein the target session grouping is the changed session grouping; and determining a mapping list which changes after time in the target session group as a target mapping list. The time mark represents the time of the session data corresponding to the target account, which is received by the terminal from the server last time. And if the terminal receives the session data corresponding to the target account from the server, the terminal takes the time of receiving the session data corresponding to the target account from the server last time as a time identifier, carries the time identifier in the data request and sends the data request to the server. The server receives the data request, and if the synchronization identifier in the data request is the time identifier, the server may determine that the terminal has synchronized the session data from the server, that is, the server does not need to determine all the session data corresponding to the target account as the target session data to be synchronized, and the server may determine the target session data from all the session data corresponding to the target account. In practical applications, before the server determines the target session data, it needs to determine the target session group from a plurality of session groups, and then determine the target mapping list from a plurality of mapping lists of the target session group. The basis of determining the target conversation group is the time represented by the time identifier, and the conversation group which is located after the time represented by the time identifier and changes is the target conversation group. And determining the basis of the target mapping list, namely the time represented by the time identifier, and determining the mapping list which changes after the time represented by the time identifier as the target mapping list. After the server of the embodiment of the present disclosure receives the data request with the synchronization identifier being the time identifier, it may determine the session packet that changes after the time represented by the time identifier as the target session packet, and determine the mapping list that changes after the time represented by the time identifier as the target mapping list. That is, the server may select a part of the session groups from the plurality of session groups as the target session groups according to the time identifier, select a part of the mapping list from the target session groups as the target mapping list according to the time identifier, and select a part of the session groups and a part of the mapping list in a targeted manner, thereby avoiding using all the session groups as the target session groups and using all the mapping list as the target mapping list, and improving the accuracy of the target session groups and the target mapping list.
In an exemplary embodiment of the present disclosure, in a session group, when a target session group and a target mapping list in the target session group are determined, when a synchronization identifier is a primary synchronization status identifier, all session groups corresponding to a target account are determined as the target session group, and at this time, the target session group is all session groups; determining all mapping lists in the target session group as target mapping lists; the initial synchronization state identification represents session data which are received by the terminal from the server for the first time and correspond to the target account. And if the terminal does not receive the session data corresponding to the target account from the server, the terminal carries the preset primary synchronization state identifier in the data request and sends the data request to the server. The server receives the data request, and if the synchronization identifier in the data request is the primary synchronization state identifier, the server may determine that the terminal has not synchronized session data from the server. After receiving the data request with the synchronization identifier being the initial synchronization status identifier, the server according to the embodiment of the present disclosure may determine all session groups corresponding to the target account as target session groups, and determine all mapping lists in the target session groups as target mapping lists. That is, the terminal does not synchronize session data from the server, the server takes all the session groups corresponding to the target account as the target session groups, and takes all the mapping lists in the target session groups as the target mapping lists, so that the situation that part of the session groups are taken as the target session groups and part of the mapping lists are taken as the target mapping lists is avoided, and the accuracy of the target session groups and the target mapping lists is improved.
In an exemplary embodiment of the present disclosure, the mapping list contains a storage address of the session data in the session list. And when determining the target session data to be synchronized in the session list according to the target mapping list, determining the target session data to be synchronized in the session list according to the storage address of the session data in the target mapping list. In practical applications, the mapping list may contain a pointer indicating the storage address of the session data in the session list. Each session data has a unique memory address in the session list. The target mapping list is determined, that is, the storage address of the target session data to be synchronized in the session list is determined, and then the target session data can be read out from the session list according to the storage address. The embodiment of the disclosure determines which session data in the session list are target session data to be synchronized according to the storage address of the session data contained in the mapping list in the session list. The server takes the storage address of the session data in the session list as key search information for determining the target session data to be synchronized, so that the target session data to be synchronized can be accurately determined.
In an exemplary embodiment of the present disclosure, for the second scheme, before the session group corresponding to the target account is acquired, the target account is locally read at the server according to a preset period. The server stores a plurality of accounts, can periodically read out a target account from the plurality of accounts, then obtains session packet data corresponding to the target account, determines a target session packet and a target mapping list in the target session packet in the session packet, determines target session data to be synchronized in the session list according to the target mapping list, and transmits the target session data to a terminal corresponding to the target account. The server of the embodiment of the disclosure can actively determine the target session data to be synchronized of the target account, and transmit the target session data to the terminal corresponding to the target account, thereby avoiding the terminal sending a data request to the server, reducing the number of times of interaction between the terminal and the server, and saving the network consumption between the terminal and the server.
In an exemplary embodiment of the present disclosure, the changed session group may include a session group that adds a mapping list and/or a session group that deletes a mapping list. As shown in fig. 2 and 3, fig. 2 shows a schematic diagram of a plurality of session packets at a certain time, and fig. 3 shows a schematic diagram of a plurality of session packets at another time. The time corresponding to fig. 2 is earlier than the time corresponding to fig. 3. The session packet may contain basic session information such as a name, an icon, and the like. The session packet may also contain a mapping list. However, the session packet does not contain session data. In fig. 2, the first session packet contains a mapping list ref01-ref 05. The second session packet contains a mapping list ref06-ref 08. The third session group contains mapping lists ref09, ref 10. In fig. 3, the fourth session group is added newly, and the first session group and the second session group are changed, and the third session group is not changed. Therefore, when the changed session packet is determined as the target session packet as described above, the fourth session packet, the first session packet, and the second session packet may be the target session packet. In particular, the newly added fourth session packet contains a mapping list ref11, ref 12. The first session packet is added with the mapping list ref13 and reduced with the mapping list ref 04. The mapping list ref06 is reduced in the second session packet.
