Description
Technical Field
The invention relates to the technical field of internet, in particular to a time calibration method, a time calibration device, a mobile terminal and a storage medium.
Background
The Read Native (RN) is an open-source cross-platform mobile application development framework, can support two large platforms of iOS (mobile operating system developed by apple) and Android (Android), and develops mobile applications by using JS (JavaScript, a lightweight, interpreted, or just-in-time compilation programming language with function priority) and CSS (Cascading Style Sheets).
The RN is used as a JS framework for constructing a user interface, response type and componentization development of data are realized, and the RN can be used for website projects and mobile terminal application projects. In other words, based on the RN, JS can be used to write logic of different platform applications, and a UI (User Interface) can be kept entirely native, which is simpler and more efficient than native code development applications.
Currently, the number of websites or applications developed through RN has increased, and the coverage types are also wider and wider, including tourism applications, information applications, shopping applications, etc. Taking the shopping application as an example, when a user wants to participate in the second killing of the commodity in the shopping application, the time accuracy and precision are highly required. At this time, the local time of the mobile terminal for installing the shopping application is ensured to be consistent with the server time of the server for providing services for the shopping application as much as possible, so that the probability of obtaining the psychographic goods by the user can be improved.
If there is a large deviation between the local time and the server time, the local time needs to be calibrated. The conventional time alignment scheme includes three types, the first type is that the RN acquires the server time maintained by the native code as the local time to achieve alignment by means of communication with the native code, but since the time update frequency is low, this does not meet the precision requirement of the second killing, and there is a certain time difference in the above communication. The second method is to calculate and store the difference value between the local time and the server time returned by the interface periodically, and directly add the corresponding difference value to the local time when calibration is needed.
The third is to retrieve the server time when the data is requested from the server for the first time, and then use a timer to count time, so as to realize the calibration of the local time. However, when the server time is obtained, the interface has a delay of response time, and then is timed by a timer, for example, the built-in methods of setTimeout (for calling a function or calculating an expression after a specified number of milliseconds) and setInterval (for calling a function or calculating an expression according to a specified period) also have errors, the errors of different platforms are different, and are affected by various factors such as machine performance, memory occupation and the like, and a few seconds of error is possible, which is unacceptable in a second killing scenario.
Therefore, a new time alignment method is needed to optimize the above process.

FIG. 2 shows a flow diagram of a method 200 of time calibration according to one embodiment of the invention. The method 200 may be performed in a mobile terminal, such as the mobile terminal 100 described above.
In this embodiment, the application A1 developed by RN is installed in the mobile terminal 100, the application A1 is a shopping application, and the user can browse, inquire, and purchase goods using the application A1 in the mobile terminal 100. The mobile terminal 100 is in communication connection with a server, the server provides services for the application A1 to the user, for example, when the user operates the application A1 to purchase a certain item, the mobile terminal 100 sends a corresponding request to the server in an interface manner through the application A1, and the server receives the request and then responds and feeds back a processing result.
Assuming that the user wants to participate in the second killing of the special price commodity developed in the application A1, which is started at 12 pm every day, in order to ensure that the local time in the mobile terminal and the server time in the server are as consistent as possible, the local time needs to be calibrated by the method 200 of the present invention. Of course, it should be noted that the following time calibration scheme is not limited to the second killing scenario, and may be applied to other similar scenarios where the accuracy requirement for the local time is high.
As shown in fig. 2, the method 200 begins at step S210. In step S210, a time acquisition request is sent to the server to instruct the server to feed back the current server time, while recording the local time of sending the time acquisition request as the first time.
According to an embodiment of the present invention, the corresponding interface is called to send a time obtaining request to the server, and after receiving the time obtaining request, the server feeds back the current server time to the mobile terminal 100. While sending the time acquisition request, recording local time of sending the time acquisition request as a first time.
Subsequently, step S220 is entered, the server time fed back by the server is received, and the local time of receiving the server time is recorded as the second time. For convenience of description, the first time, the second time, and the server time are respectively denoted as LBT, LET, and ST.
In step S230, it is determined whether the local time in the mobile terminal is accurate according to the first time, the second time, and the server time.
According to an embodiment of the present invention, whether the local time in the mobile terminal is accurate may be determined according to the first time, the second time, and the server time in the following manner. In this embodiment, first, the result of subtracting the first time from the second time is calculated as a first difference, and the first difference is denoted as C1, so that C1= LET-LBT can be obtained.
If the first difference is smaller than a preset first time threshold, determining that the local time in the mobile terminal is available, but further judging whether the local time is accurate, and at the moment, determining whether the local time in the mobile terminal is accurate or not based on the size relationship among the first time, the second time and the server time and the first difference. Specifically, if the server time is greater than the first time and less than the second time, and the first difference is less than a preset second time threshold, it is determined that the local time in the mobile terminal is accurate, otherwise it is determined that the local time in the mobile terminal is inaccurate.
If the first difference is greater than or equal to the first time threshold, it indicates that the local time is incorrect, and a manual adjustment may be required. Typically, the first time threshold is preset to 3000ms (milliseconds) and the second time threshold is preset to 1000ms. In other words, if C1<3000ms, the local time is considered available, on this basis, if LBT < ST < LET and C1<1000ms, the local time is judged to be accurate and can be used directly without calibration.
Finally, step S240 is executed, and if the local time in the mobile terminal is not accurate, the local time in the mobile terminal is calibrated according to the server time and the second time.
According to one embodiment of the present invention, the local time in the mobile terminal may be calibrated according to the server time and the second time in the following manner. In this embodiment, the result of subtracting the second time from the server time is calculated as a second difference, and if the second difference is denoted as C2, then C2= ST-LET. And then, acquiring the local time in the mobile terminal according to a preset time interval, and calibrating the acquired local time through a second difference value. The time interval is denoted by S and is typically set to 500ms.
When the acquired local time is calibrated by the second difference, firstly, a result obtained by subtracting the corresponding expected time from the local time acquired this time is calculated as a third difference, where the expected time is a sum of the local time acquired last time and a time interval, that is, the local time which should be acquired this time theoretically. And respectively representing the local time acquired this time, the local time acquired last time, the expected time and a third difference value by LT, BT, ZT and C3, wherein ZT = BT + S and C3= LT-ZT correspondingly.
If the third difference is greater than a preset third time threshold, the sum of the local time obtained this time, the second difference and the third difference is used as the calibrated local time, and if the third difference is less than or equal to the third time threshold, the sum of the local time obtained this time and the second difference is used as the calibrated local time. In this case, the calibrated local time may be equivalent to the server time at the same time.
The third time threshold here is a predefined constant, and is used to control an error range between the local time actually obtained this time and the expected time, and if the requirement on the accuracy of time is relatively high, the preset third time threshold needs to be smaller, for example, 300ms, and vice versa. And Z represents a third threshold value, when C3> Z, the calibrated local time is LT + C2+ C3, and when C3 is less than or equal to Z, the calibrated local time is LT + C2.
In addition, the calibration time can also adopt the return time after switching, namely, the calibration is carried out again each time the switching is carried out by monitoring the switching of the foreground and the background. The foreground means that the current application or page is in a visible state, and the background means that the current application or page leaves from the current application or page, the current application or page is switched to the desktop or other applications, but the current application is not ended or the current page is closed, and the current application or page is switched back again by the return finger. For example, the user browses details of the second killing of the special price commodity in the application A1, and if the user restarts another application review message to leave from the application A1, and returns to the application A1 again to continue to view the second killing after a while, the calibration of the local time may be started at the time when the user returns to the application A1.
Fig. 3 shows a schematic diagram of a time alignment apparatus 300 according to an embodiment of the invention. The time alignment apparatus 300 resides in a mobile terminal (e.g., the aforementioned mobile terminal 100). The time alignment apparatus 300 aligns the local time by performing the time alignment method 200 of the present invention.
As shown in fig. 3, the time calibration apparatus 300 includes a transmitting module 310, a determining module 330, and a calibrating module 340 connected in sequence, and a receiving module 320 connected to the determining module 330 and the calibrating module 340, respectively.
The sending module 310 may send a time obtaining request to the server to instruct the server to feed back the current server time, and record the local time of sending the time obtaining request as the first time. The receiving module 320 may receive the server time fed back by the server and record a local time of receiving the server time as the second time. The determining module 330 may determine whether the local time in the mobile terminal is accurate based on the first time, the second time, and the server time. The calibration module 340 may calibrate the local time in the mobile terminal according to the server time and the second time when the local time in the mobile terminal is inaccurate.
It should be noted that the sending module 310 is configured to execute the aforementioned step S210, the receiving module 320 is configured to execute the aforementioned step S220, the determining module 330 is configured to execute the aforementioned step S230, and the calibrating module 340 is configured to execute the aforementioned step S240. Here, for the execution logic of the sending module 310, the receiving module 320, the determining module 330 and the calibrating module 340, reference may be made to the detailed description of steps S210 to S240 in the method 200, and details are not repeated here.

When the local time is inaccurate, the local time is calibrated according to the server time and the second time so as to reduce errors generated in the timing process to a receivable range, realize unification of the time of the mobile terminal and the server, namely the front end and the back end, and meet the high-precision requirement on the time in the second killing scene.
