Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
For the convenience of understanding of the present application, a brief description of an implementation environment related to the embodiments of the present application will be provided.
Referring to fig. 1, fig. 1 is a schematic diagram of an implementation environment according to an embodiment of the present application, and as shown in fig. 1, the implementation environment includes a user terminal 10 and a computer device 20. Wherein the computer device 20 is installed with an operating system 21 and software services 22. The user terminal 10 may be a mobile phone, a tablet computer, a computer, or the like, and the computer device 20 may be a computer, a server, or the like, and of course, as the computing capability of the terminal improves, the computer device 20 may also be a mobile terminal such as a mobile phone, a tablet computer, or the like.
The operating system 21 may be a computer program for managing computer hardware and software resources, and may be an operating system such as Windows (microsoft), Linux, or Android (Android).
The software service 22 is software running in a computer device that provides remote access services to the user terminal 10. Furthermore, the software service 22 may have a first storage location 23 in the computer device 20 as its data storage space and a second storage location of the computing device 20 as its database 24, the database 24 being used to record data information resulting from data manipulation by the software service. In addition, the software service 22 is externally provided with the following two operation interfaces:
1) the software service 22 is provided with a network access interface, and the user terminal 10 can remotely access the software service 22 in the computer device 20 through the network and perform data operations, such as file adding, deleting, searching or changing operations, for example, adding, deleting, searching or changing operations on data in the first storage location through the software service 22. Illustratively, the user terminal 10 may access the software service 22 in the computer device 20 through installed client software. During the data operation of the user terminal 10 through the software service 22, the software service 22 also records the data information generated by the data operation into the database 24 of the software service 22.
2) The software service 22 may provide a software service interface for the computer device 20, where the software service interface is a service window provided by the software service 22 for the computer device 20, and a user of the computer device 20 may perform data operations, such as adding, deleting, checking, or changing files, for example, adding, deleting, checking, or changing data in the first storage location. During the data manipulation through the software service interface, the software service 22 also records data information generated by the data manipulation into the database 24 of the software service 22.
In both of the above-described modes of operation, the software service 22 is directly informed of changes in the data produced by the operation. After identifying the change to the data, software service 22 may generate data information for the changed data, which is then recorded in a database.
However, in addition to the two operations described above, which may alter the data of the first storage location 23, the local operations of the computer device 20 may also alter the data of the first storage location 23. The local operation described herein refers to an operation performed on the data stored in the first storage location 23 directly through the operating system, not through the network access software service 22, but through the software service interface. As an example, the file management system may be invoked through a user interface provided by the operating system, through which the data in the first storage location 23 is operated. For example, the user may operate a user interface provided by an operating system through a mouse or a keyboard to invoke the file management system, and then operate the data in the first storage location 23 through the file management system. As another example, the data in the first storage location 23 may also be manipulated through a file management interface provided by an operating system. For example, a user may operate on data in the first storage location 23 by a command line calling a file management interface of an operating system.
Since the above-mentioned local operation of the service device 20 does not pass through the software service 22, and the software service 22 cannot directly know such a change, the change of the data in the first storage location 23 by the local operation is not recorded by the database 24 of the software service 22, which results in the data being out of synchronization between the first storage location 23 and the database 24. In addition, since the data accessed by the user terminal 10 is provided by the database 24 when accessing the software service 22, the data accessed by the user terminal 10 is further out of synchronization with the locally stored data of the computer device 20.
In order to solve the above problem, an embodiment of the present application provides a method for ensuring data synchronization between user-side access data and locally stored data of a computer device, which is described in detail in the embodiment of fig. 2 below.
Fig. 2 is a flowchart of a data synchronization method provided in an embodiment of the present application, where the method is applied to the computer device shown in fig. 1, and as shown in fig. 2, the method includes the following steps:
step 201: in the case that first data information of data stored in a first storage position is changed, the first data information and second data information generated by data operation performed by a software service are subjected to synchronism detection through the software service, so that whether the first data information and the second data information are synchronous or not is detected.
The first storage position is a data storage position of the software service, and data stored in the first storage position can be operated through an operating system. The first storage location may be any storage location in the computer device, and may specifically be a file directory, a partition, a disk, or an array, which is not limited in this embodiment of the present application.
It should be noted that the first storage location may be specified by a software service, or may be set by a user in a customized manner, which is not limited in this embodiment of the application.
As an example, a default storage location set by the system may be determined as the first storage location. For example, during the process of installing the software service or initializing the software service, the default storage location set by the system is used as the data storage location of the software service.
As another example, a data storage location setting interface of the software service may be displayed during installation of the software service or initialization of the software service, and then a storage location set through the data storage location setting interface may be used as the first storage location.
That is, the user can freely define and set the data storage location of the software service through the data storage location setting interface, and then use the storage location set by the user as the first storage location.
Wherein the second data information generated by the data manipulation by the software service may be stored in a second storage location of the computer device. That is, the software service may use the second storage location of the computer device as its database for storing the second data information generated by the data manipulation performed by the software service.
The first data information and the second data information may include data attributes or data sources, and the like. Data attributes may include data type, data classification, or data summary, among others. The data Digest may be the MD5(Message-Digest Algorithm MD5, MD5 Message Digest Algorithm) value of the data, or the like.
For example, the first data information may include a classification of data stored in the first storage location, an MD5 value, or a data source, etc. The data source is used to indicate which user terminal the data is uploaded through, and may be an identifier, an IP address (Internet Protocol ), a physical address, or the like of the user terminal that uploads the data.
The second data information may include a classification of the data, an MD5 value of the data, or a data source, among others. For example, the second data information may include a classification of the picture (e.g., person, landscape, business card, etc.) identified by the software service, a calculated MD5 value of the picture, and a source of the picture (e.g., through which user's mobile phone to upload), etc.
It should be noted that the data stored in the first storage location has 3 operation modes: 1, a user side accesses a software service through a network and carries out remote operation through the software service; 2, the user of the computer equipment operates through the software service interface; and 3, the user of the computer equipment carries out local operation through the operating system of the computer equipment.
In the related art, the software service may directly learn the changes made to the data in the first two ways, and record the second data information generated by the changes to the data, for example, to the second storage location. In the third method, since the software service is not performed, the software service cannot directly learn the change of the data, and cannot record the data information generated by the operation into the second storage location, which may cause the data information of the first storage location and the second storage location to be out of synchronization.
In the embodiment of the present application, it can be known through analysis of the above operations that the change of the first data information may be caused by data operation performed through a software service, or may be caused by a local user of the computer device performing operation on data stored in the first storage location through an operating system. If the data operation is caused by the software service, the change of the first data information is automatically recorded into the second data information, so that the first data information and the second data information are kept synchronous. If the data operation is performed through the operating system, the change of the first data information is not recorded in the second data information, in this case, the first data information and the second data information cannot be kept synchronous.
In the embodiment of the present application, in order to avoid data asynchronization caused by performing data operation through an operating system, when the first data information changes relative to the historical first data information, if the change is caused by performing data operation through the operating system, the software service may also be triggered to perform synchronization detection on the first data information and the second data information, so as to perform data synchronization when the first data information and the second data information are not synchronized.
As an example, the operation of detecting the synchronicity of the first data information and the second data information includes: and comparing the first data information with the second data information, if the first data information and the second data information are detected to be different, determining that the first data information and the second data information are asynchronous, and if the first data information and the second data information are detected to be the same, determining that the first data information and the second data information are synchronous.
Step 202: and if the first data information and the second data information are detected to be out of synchronization, updating the second data information based on the first data information.
If it is detected that the first data information and the second data information are not synchronized, it may be determined that the change of the first data information is caused by an operation performed by the operating system on the data stored in the first storage location, in this case, the second data information needs to be updated based on the first data information, so as to ensure that the second data information and the first data information are synchronized.
As an example, the operation of updating the second data information based on the first data information includes: determining out-of-sync data information between the first data information and the second data information; based on the out-of-sync data information, the second data information is updated to maintain data synchronization between the two.
That is, only the asynchronous data information between the two is synchronized, and other synchronous data is not operated, so that the data processing amount can be reduced, and the data processing efficiency can be improved.
Step 203: and when the user side accesses the software service through the network, displaying the updated second data information to the user side.
After the second data information is updated based on the first data information, the computer device can also display the updated second data information to the user side when the user side accesses the software service through the network, that is, the updated data information of the database is synchronized to the user side accessing the software service in time, so that the user side can obtain the local storage data of the computer device in time.
As an example, the computer device may send the updated second data information to the user terminal when receiving the data access instruction from the user terminal, and the user terminal refreshes the display interface based on the updated second data information.
As another example, the computer device may also send a data update notification to the user terminal, where the data update notification is used to instruct the user terminal to obtain the updated second data information, and refresh the display interface based on the updated second data information.
Step 204: and if the first data information and the second data information are detected to be synchronous, ending the operation.
If the first data information and the second data information are detected to be synchronous, it is indicated that the remote user end or the local user of the computer equipment does not perform data operation through the software service, and the local user does not perform data operation on the data storage position of the software service through the operating system, and in this case, data synchronization is not needed.
In the embodiment of the application, in the case that the first data information of the data stored in the first storage location is changed, through the software service, the first data information is subjected to synchronism detection with second data information generated by data operation through a software service, when the first data information and the second data information are asynchronous, the second data information is synchronized based on the first data information, the data stored in the first storage position can be operated by the computer equipment through local operation, when the first data information is changed, the data synchronization is carried out on the first data information and the second data information in time, the data synchronization of the first data information and the second data information is ensured, and further, when the user side accesses the software service, the data synchronization between the user side access data and the local storage data of the computer equipment is ensured, so that the user side can timely obtain the data result of the local operation of the computer equipment.
Fig. 3 is a flowchart of another data synchronization method provided in an embodiment of the present application, where the method is applied to the computer device shown in fig. 1, and as shown in fig. 3, the method includes the following steps:
step 301: first data information of data stored in the first storage location is obtained through a software service.
In this embodiment of the application, after the software service is started, the software service may monitor the first storage location to monitor a change of first data information of data stored in the first storage location, so as to perform synchronization detection on the first data information and the second data information when the first data information is changed.
As an example, when the first data information of the data stored in the first storage location is acquired by the software service, the acquisition may be performed according to a specified policy. For example, the acquisition is periodically performed, or triggered by a preset trigger policy.
For example, the first data information may be obtained by a software service when the computer device is detected to be in an idle state or the load is less than a load threshold. Therefore, the processing load of the computer equipment can be reduced, and the influence on other tasks is avoided.
As an example, obtaining, by a software service, first data information of data stored in a first storage location may include the following two implementations:
the first implementation mode comprises the following steps: first data information of data stored in the first storage location is obtained from a file system log of the computer device through a software service.
That is, the first data information may be read from the file system log.
In the embodiment of the application, the first data information may be periodically acquired from the file system log through a software service, or may be non-periodically acquired. For example, the first data information may be obtained from a file system log when the computer device is detected to be in an idle state or when the load is less than a load threshold.
The second implementation mode comprises the following steps: and calling a file scanning function to scan the file of the first storage position through software service, and acquiring first data information according to a file scanning result.
That is, the file scanning function may be used to scan the file, and further read the first data information.
In the embodiment of the application, the first data information may be obtained by periodically scanning the file in the first storage location through the software service, or may be obtained by non-periodically scanning the file. For example, when it is detected that the computer device is in an idle state or the load is smaller than the load threshold, the file scanning function may be invoked to perform file scanning on the first storage location, and the first data information may be obtained according to a file scanning result.
Step 302: detecting, by the software service, whether the first data information has changed relative to the historical first data information.
The historical first data information refers to first data information obtained last time by the software service.
The software service may compare the currently acquired first data information with the last acquired first data information, and if the currently acquired first data information changes with respect to the last acquired first data information, it may be determined that the first data information of the data stored in the first storage location has changed.
Step 303: if the first data information is changed relative to the historical first data information and the change is caused by data operation through an operating system, performing synchronism detection on the first data information and second data information generated by data operation through a software service through the software service so as to detect whether the first data information and the second data information are synchronous or not.
It should be noted that, if the change of the first data information is caused by data operation performed by the software service, the software service will automatically synchronize the change of the first data information to the second data information, and keep the synchronization of the first data information and the second data information. However, if the change of the first data message is caused by data operation through the operating system, the software service is not aware of the change, which causes the first data message to be out of synchronization with the second data message.
In the embodiment of the application, in order to avoid data asynchronization caused by data operation through an operating system, under the condition that the first data information is changed relative to the historical first data information, if the changed first data information is caused by data operation through the operating system, the first data information and the second data information can be subjected to synchronism detection through a software service, so that data synchronization is performed when the first data information and the second data information are not synchronized.
Step 304: and if the first data information and the second data information are detected to be out of synchronization, updating the second data information based on the first data information through software service.
Step 305: and when the user side accesses the software service through the network, displaying the updated second data information to the user side through the software service.
Step 306: and if the first data information and the second data information are detected to be synchronous, ending the operation.
It should be noted that, the steps 304-306 are similar to the steps 202-204 in the embodiment of fig. 2, and the specific implementation manner can refer to the related description of the steps 202-204, and the detailed description of the embodiment of the present application is not repeated herein.
In the embodiment of the application, the software service may acquire first data information of data stored in the first storage location, and when it is detected that the first data information is changed and the change is caused by data operation performed through the operating system, synchronization detection is automatically triggered on the first data information and second data information generated by data operation performed through the software service, and when the first data information and the second data information are not synchronized, the second data information may be synchronized based on the first data information. Therefore, when the computer equipment operates the data stored in the first storage position through local operation and the first data information changes, the data synchronization of the first data information and the second data information is timely performed, the data synchronization of the first data information and the second data information is ensured, and further the data synchronization between the user side access data and the local storage data of the computer equipment is ensured when the user side accesses the software service, so that the user side can timely obtain the data result of the local operation of the computer equipment.
