Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of 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 foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a data synchronization method of instant messaging according to an exemplary embodiment, and the data synchronization method of instant messaging may be applied to a server as shown in fig. 1. The data synchronization method of the instant messaging can comprise the following steps.
In step S11, a session group corresponding to the target account is acquired.
In the embodiment of the disclosure, the target account may be an account of the instant messaging application, and the target session data to be synchronized determined later is session data generated by the target account interacting with other accounts by logging in the instant messaging application. The server stores therein session packets for a plurality of accounts. The session groups for each account may be distinguished using the account identification of the respective account. .
In an embodiment of the present disclosure, a session list of a plurality of accounts is also stored in the server, and session data of each account is stored in the session list of each account. The session group in the server contains a mapping list, which may point to a session list for each account.
In step S12, in the session group, a target session group and a 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 necessarily session groups required for the data synchronization, so that the target session group required for the data synchronization needs to be determined from the plurality of session groups corresponding to the target account. The target session packet is a changed session packet or the target session packet is an entire session packet. Similarly, the target session packet includes a plurality of mapping lists, and not all the mapping lists in the target session packet are necessarily mapping lists required by the data synchronization, so that the target mapping list required by the data synchronization needs to be determined in the target session packet.
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, since the mapping list is used to point to the session list corresponding to the target account, the target mapping list required for the present data synchronization is the session data stored in the pointed session list, that is, the target session data required for the present data synchronization.
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 needed by the data synchronization from a large amount of session data stored this time, and then transmits the target session data to the terminal corresponding to the target account, thereby realizing the function of synchronizing the session data from the server to the terminal.
The data synchronization scheme of the 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 which is used for pointing to a session list corresponding to the target account, and session data is 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 packet is a changed session packet or the target session packet is an entire session packet. 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 includes a mapping list for determining session data, and the mapping list may point to the session list in which the session data is stored. Therefore, the server may first obtain the session packet corresponding to the target account, and then determine which session packets include the mapping list required for the synchronization, that is, may determine the target session packet from the plurality of session packets, and determine the target mapping list from the plurality of mapping lists in the target session packet. After the target mapping list is determined, the 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 is transmitted to the terminal, so that the session data of instant messaging is completed, and the server is synchronized to the terminal. According to the method and the device for synchronizing the session data, 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 server is prevented from determining and transmitting the session data to be synchronized for multiple times, the system resource occupation amount of the server is reduced, the processing pressure of the server is reduced, and network resources between the terminal and the server are saved.
Embodiments of the present disclosure synchronize session data from a server to a terminal, and may include two data synchronization schemes, scheme one, in which the terminal sends a data request to the server, and the server transmits target session data to the terminal according to the data request. In the second scheme, the server actively transmits target session data to the terminal. Hereinafter, the above two schemes will be described in detail, respectively.
In an exemplary embodiment of the present disclosure, for the first scheme, before acquiring a session packet 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 it receives the data request from the terminal. The data request indicates that the terminal desires to synchronize 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 of the embodiment of the disclosure 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 disclosure, the data request is sent by the terminal, and the server receives the data request, so that the server can transmit target session data to the terminal in a targeted manner, and when the server receives the data request, the target session data to be synchronized is determined, thereby avoiding the frequent and active determination of the target session data to be synchronized of different accounts by the server, reducing the resource occupation of the server, and reducing the operation pressure of the server.
In one 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 group also contains the time of establishment of the mapping list. When the synchronous mark is a time mark, the changed session group after the time indicated by the time mark is determined as the target session group, and the target session group is the changed session group at the moment; the mapping list which changes after the time in the target session group is determined as a target mapping list. The time identifier indicates the time when the terminal last receives session data corresponding to the target account from the server. If the terminal receives the session data corresponding to the target account from the server, the terminal takes the time of last receiving the session data corresponding to the target account from the server as a time identifier, carries the time identifier in a data request and sends the data request to the server. If the synchronization identifier in the data request is a time identifier, the server can determine that the terminal synchronizes 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 can determine the target session data from all the session data corresponding to the target account. In practical application, before determining the target session data, the server needs to determine the target session packet from a plurality of session packets, and then determine a target mapping list from a plurality of mapping lists of the target session packet. The time indicated by the time identifier is determined as the basis of the target session packet, and the changed session packet which is positioned after the time indicated by the time identifier is the target session packet. The basis for determining the target mapping list is also the time represented by the time identifier, and the mapping list which is changed after the time represented by the time identifier is the target mapping list. After receiving the data request with the synchronization identifier as the time identifier, the server of the embodiment of the disclosure may determine a session packet that changes after the time indicated by the time identifier as a target session packet, and determine a mapping list that changes after the time indicated by the time identifier as a target mapping list. That is, the server may select a part of the session packets from the plurality of session packets according to the time identifier as the target session packet, and select a part of the mapping list from the target session packets according to the time identifier as the target mapping list, so that the server selectively selects a part of the session packets and a part of the mapping list, thereby avoiding taking all of the session packets as the target session packets, avoiding taking all of the mapping list as the target mapping list, and improving the accuracy of the target session packets and the target mapping list.
In an exemplary embodiment of the present disclosure, when determining a target session packet and a target mapping list in the target session packet in a session packet, when a synchronization identifier is a primary synchronization status identifier, all session packets corresponding to a target account are determined to be target session packets, and at this time, all session packets are determined to be target session packets; determining all mapping lists in the target session group as target mapping lists; the primary synchronization state identifier indicates session data corresponding to the target account, which is received by the terminal from the server for the first time. If the terminal does not receive the session data corresponding to the target account from the server, the terminal carries a 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 can determine that the terminal has not synchronized session data from the server. After receiving the data request with the synchronization identifier being the primary synchronization state identifier, the server of the embodiment of the disclosure may determine all session packets corresponding to the target account as target session packets, and determine all mapping lists in the target session packets as target mapping lists. That is, the terminal does not synchronize session data from the server, the server takes all session groups corresponding to the target account as target session groups, and takes all mapping lists in the target session groups as target mapping lists, so that partial session groups are prevented from being taken as target session groups, partial mapping lists are prevented from being taken as target mapping lists, and accuracy of the target session groups and the target mapping lists is improved.
In one exemplary embodiment of the present disclosure, the mapping list contains the storage addresses of the session data in the session list. When the target session data to be synchronized in the session list is determined according to the target mapping list, the target session data to be synchronized is determined in the session list according to the storage address of the session data in the target mapping list. In practice, the mapping list may contain pointers that represent the memory addresses 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. According to the embodiment of the disclosure, according to the storage address of the session data contained in the mapping list in the session list, which session data in the session list are target session data to be synchronized is determined. The server uses 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 packet corresponding to the target account is acquired, the target account is locally read at the server according to a preset period. The server can periodically read out target accounts from the accounts, then acquire session grouping data corresponding to the target accounts, determine target session grouping and a target mapping list in the target session grouping in the session grouping, determine target session data to be synchronized in the session list according to the target mapping list, and transmit the target session data to a terminal corresponding to the target accounts. 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, so that the terminal is prevented from sending a data request to the server, the interaction times between the terminal and the server are reduced, and the network consumption between the terminal and the server is saved.
In one exemplary embodiment of the present disclosure, the changed session packet may include a session packet to add a mapping list and/or a session packet to delete a mapping list. As shown in fig. 2 and 3, fig. 2 shows a schematic diagram of a plurality of session packets at one 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. Session basic information such as names, icons, etc. may be included in the session packet. The session packet may also contain a mapping list. However, the session packet does not include session data. In fig. 2, the first session packet contains mapping lists ref01-ref05. The second session packet contains the mapping list ref06-ref08. The third session packet contains the mapping list ref09, ref10. In fig. 3, a fourth session packet is added, and the first session packet and the second session packet are changed, and the third session packet is unchanged. Thus, when the changed session packet is determined as the target session packet, the fourth session packet, the first session packet, and the second session packet may be regarded as the target session packet. Specifically, the newly added fourth session packet contains the mapping lists ref11, ref12. The mapping list ref13 is added to the first session packet and the mapping list ref04 is reduced. The mapping list ref06 is reduced in the second session packet.
