Detailed Description
In order to more clearly illustrate the invention, the invention is further described below with reference to preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides an information synchronization method between a mobile terminal and a server, which is applied to the mobile terminal, and includes: when the mobile terminal is judged to be in an off-line state: if the information is updated, updating the information of a terminal database, wherein each piece of information comprises a name, data and a signature, and the signature is a terminal signature generated by the mobile terminal; when the mobile terminal is judged to be changed from the offline state to the online state and at least one piece of offline updated information with signature as the terminal signature exists: sending an offline data synchronization request to a server, so that the server generates a service signature and transmits the service signature back to the mobile terminal; and updating the signature of each piece of offline updated information in the terminal database according to the service signature, and sending each piece of information with the updated service signature to the server, so that the server updates the server database according to the received information.
In this embodiment, the mobile terminal can normally operate in an offline state by setting a terminal database of the mobile terminal: updating information in an offline state and storing the information in a terminal database; and when the mobile terminal is changed from the offline state to the online state, the updated information is synchronized to a server database of the server through data synchronization initiated from the mobile terminal to the server by the mobile terminal, so that the information synchronization is realized. The embodiment can solve the problem that the mobile terminal cannot work in an off-line state due to the fact that the mobile terminal does not store data in the prior art, and effectively improves the working performance of the mobile terminal.
In a specific embodiment, the updating of the material information of the inventory material in the enterprise is taken as an example, as shown in fig. 1,
in an off-line state, when the mobile terminal checks the materials, the actual quantity of the materials is updated to the data of the information of the terminal database according to the actual inventory condition of one or more materials, and a terminal signature is generated as a signature.
When the mobile terminal is switched from the offline state to the online state, for example, the mobile terminal is moved from a warehouse of the uncovered network signal to an office of the covered network signal, the mobile terminal is connected with the network, and then the mobile terminal sends an offline data synchronization request to the server.
And the server receives the offline data synchronization request, generates a service signature for confirming synchronization and sends the service signature to the mobile terminal.
And the mobile terminal receives the service signature, updates the service signature to the signature of the information updated in the terminal database in an off-line state, and simultaneously sends the information with the updated service signature to the server. Namely, the server confirms the synchronously generated service signature and updates the service signature into the information with the signature as the terminal signature in the terminal database.
And the server stores the received information with the updated service signature, namely the information with the updated data in the offline state, into a server database, so that the data updated by the synchronous mobile terminal in the offline state is realized.
It should be noted that, in this embodiment, only a specific implementation manner of the present application is described through the material information, and the information synchronized between the mobile terminal and the server in the present application may be any updated specific information, and a person skilled in the art should select an appropriate application scenario according to an actual application requirement, so as to implement information synchronization between the mobile terminal and the server as a design criterion, which is not described herein again.
Considering that there is only one data synchronization method from the mobile terminal to the server when the mobile terminal is turned from the offline state to the online state, in an optional embodiment, the synchronization method further includes: receiving a synchronization request broadcast by the server, and inquiring whether a signature is the terminal signature information; if so: sending an offline data synchronization request to the server, so that the server generates a service signature and transmits the service signature back to the mobile terminal, updating the signature of the information signed as the terminal signature in the terminal database according to the service signature, and sending each updated information to the server, so that the server updates each updated information to the server database and updates the synchronization log, wherein the synchronization log is used for recording the synchronization information of the server database, for example, the synchronization operation performed when a certain mobile terminal is converted from an offline state to an online state.
In this embodiment, the synchronization request broadcasted by the server at regular time further ensures that the information updated by the mobile terminal in the offline state is synchronized to the server database of the server, thereby implementing bidirectional offline data synchronization.
Specifically, as shown in fig. 2:
the server broadcasts the synchronization request at regular time.
In this embodiment, the server is connected to at least one mobile terminal, and the server sends a synchronization request to each mobile terminal in a timing broadcast manner, so that query efficiency of detecting whether each mobile terminal has offline information update in a server polling manner in the prior art is improved.
The mobile terminal receives the synchronization request and inquires whether the terminal database of the mobile terminal has the update of the offline information, namely, the signature is the information of the terminal signature, if not, the mobile terminal discards the synchronization request, otherwise, the mobile terminal starts the synchronization process of the offline information: the method comprises the following steps: the mobile terminal sends an offline data synchronization request to the server; the server receives and generates a service signature which determines synchronization, and sends the service signature to the mobile terminal; the mobile terminal updates the signature in the offline updated information in the terminal database according to the service signature and sends the updated information to the server; the server receives the information and updates the information to the server database. The specific process is similar to the above embodiment, and is not described herein again.
It should be noted that, no matter whether the mobile terminal initiates the synchronization process of the offline updated information to the server by the offline data synchronization request initiated by the mobile terminal, or the synchronization process of the offline updated information initiated by the mobile terminal in response to the synchronization request periodically broadcasted by the server, only one of the two operations is executed in one offline data synchronization process.
Those skilled in the art should understand that the two simultaneous synchronization operations are used to ensure that the updated information of the mobile terminal in the offline state is synchronized to the server database of the server, and those skilled in the art should set the implementation processes of the two synchronization operations according to actual application requirements, so as to avoid repeating the synchronization operations, which is not described herein again.
In an alternative embodiment, the signature is a time stamp indicating the synchronization status and the synchronization time of the information.
In this embodiment, a timestamp is used as a signature, and the signature is used to represent the synchronization state of the information, and the synchronization time of each piece of information is represented by the timestamp. When the signature is a terminal signature, the information is updated information of the mobile terminal and is not synchronized with the server, and when the signature is a service signature, the information is synchronized with the server, and the time stamp is the time of the synchronization. It should be noted that, since the server generates the service signature according to the time when the synchronization request sent by the mobile terminal is received, the service signature generated by the server each time is unique, thereby avoiding the situation that the update sequence is confused when a plurality of mobile terminals work together.
In view of the working condition of the mobile terminal in the online state, in an optional embodiment, the synchronization method further includes: when the mobile terminal is judged to be in an online state: if the information is updated, updating the information of the terminal database and sending an online data updating request to the server, wherein the online data updating request comprises the name and the data of the updated information, so that the server generates a service signature and returns the service signature to the mobile terminal, and the server updates the name, the data and the service signature of the information to the server database; and updating the signature of the corresponding information in the terminal database according to the service signature.
In this embodiment, as shown in fig. 3, the description is still given by taking the update of the material information of the inventory material in the enterprise as an example, specifically
In an online state, when the mobile terminal checks materials, and when the actual inventory condition of one material changes, the actual quantity of the material is updated to the data of the information of the terminal database, and a terminal signature is generated to serve as the signature of the corresponding information.
Meanwhile, the mobile terminal sends an online data updating request to the server, wherein the online data request comprises the name and the data of the information.
And the server receives the online data updating request, generates a service signature for confirming synchronization and sends the service signature to the mobile terminal.
And the mobile terminal receives the service signature and updates the service signature to the signature of the information in the terminal database.
And meanwhile, the server updates corresponding information in the server database according to the received name and data and the generated service signature.
Therefore, the synchronization of the updated information of the mobile terminal in the terminal database and the server database in the online state is realized.
Considering that the server is connected to a plurality of mobile terminals, different mobile terminals may operate at different times, and there is a possibility of non-synchronization between different mobile terminals, in an alternative embodiment, as shown in fig. 4, the synchronization method further includes: when the mobile terminal is judged to be started or synchronous in response to external operation: sending an online data synchronization request to the server, wherein the online data synchronization request comprises names and signatures of all information of a terminal database of the mobile terminal, so that the server queries the server database according to the names and signatures of all information and packages all information except the names and signatures into a synchronization data packet to be sent to the mobile terminal; and receiving the synchronous data packet and updating each information in the synchronous data packet to the terminal database.
In this embodiment, it is considered that different mobile terminals synchronize with the server after updating information, that is, the server database of the server has all the information updated recently. By initiating a synchronization request to the server when the mobile terminal is started or in response to an external operation, the problem of non-synchronization due to information being updated by other mobile terminals is avoided.
As shown in fig. 4, the method specifically includes:
and the mobile terminal sends an online data synchronization request to the server.
In this embodiment, a mobile terminal initiates a synchronization request to the server, where the online data synchronization request includes names and signatures in all information in the terminal database.
And the server receives the information, inquires a server database according to the name and the signature, and inquires whether the server database has information with a signature different from the terminal database.
In this embodiment, the server queries, through the name and the signature of the information, whether the terminal database has unsynchronized information, and if so, synchronizes the information of the terminal database. Specifically, the server packages information with different signatures into a data packet, and in order to ensure the security of the data packet, the server encrypts the data packet and compresses the encrypted data packet so as to facilitate the transmission of the data packet.
And the mobile terminal receives the data packet, decompresses and decrypts the data packet to obtain the information to be synchronized acquired from the server database, and updates the terminal database according to the information to be synchronized so as to realize the synchronization of the mobile terminal and the server.
Similar to the above-mentioned information synchronization method applied to the mobile terminal, as shown in fig. 1, the present invention also provides an information synchronization method between the mobile terminal and the server applied to the server, including: the server receives an offline data synchronization request sent by a mobile terminal, generates a service signature and sends the service signature to the mobile terminal, so that the mobile terminal updates the service signature to offline updated information in a terminal database, wherein the information comprises a name, data and a signature; and the server receives the information which is sent by the mobile terminal and updates the service signature, and updates a server database according to the information.

In this embodiment, a timestamp is used as a signature, and the signature is used to represent the synchronization state of the information, and the synchronization time of each piece of information is represented by the timestamp. When the signature is a terminal signature, the information is updated information of the mobile terminal and is not synchronized with the server, and when the signature is a service signature, the information is synchronized with the server, and the time stamp is the time of the synchronization. It should be noted that, since the server generates the service signature according to the time when the synchronization request sent by the mobile terminal is received, the service signature generated by the server each time is unique, thereby avoiding the situation that the update sequence is confused when a plurality of mobile terminals work together.
In an optional embodiment, as shown in fig. 3, the information synchronization method further includes: the server receives an online data updating request sent by the mobile terminal, wherein the online data updating request comprises the name and the data of updated information; and the server generates a service signature and transmits the service signature back to the mobile terminal, and meanwhile, the name, the data and the service signature of the information are updated to the server database, so that the mobile terminal updates the signature of the corresponding information in the terminal database according to the service signature.
