Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings according to embodiments.
The user can use different types of terminals, such as fixed terminals or mobile terminals, to inquire train tickets in the network ticketing system.
When a fixed terminal such as a PC is used to perform train ticket inquiry in a network ticketing system, data needs to be acquired from a server side immediately, and during a peak time period of ticket purchase, the manner of acquiring data from the server side immediately causes huge processing pressure on the server side.
Therefore, in the present invention, an improvement is made to a method for querying a train ticket by using a fixed terminal, and specifically refer to the flow shown in fig. 1.
Referring to fig. 1, fig. 1 is a flowchart of a data synchronization method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
And 102, judging whether the operation of writing the JavaScript file is successful, if so, executing a step 103, and otherwise, executing a step 104.
And 103, uploading the JavaScript file serving as the latest site data corresponding to the fixed terminal to a cloud storage service, generating an access link aiming at/pointing to the JavaScript file stored in the cloud storage service, and providing the access link for the fixed terminal. The process is ended.
The fixed terminal can acquire the latest station data by clicking the access link, and the data synchronization of the fixed terminal and a server side in the network ticketing system is realized.
And 104, judging whether the operation failure times of writing the JavaScript file exceed the preset times, if so, executing the step 105, and otherwise, executing the step 106.
And 105, judging whether the access link generated last time is invalid, if so, providing a preset default access link for the user terminal, and otherwise, providing the access link generated last time for the fixed terminal. The process is ended.
The access link generated last time, that is, the access link pointing to the latest site data generated after the latest site information is changed before the site information is changed this time.
And 106, writing all the site information including the changed site information into a JavaScript file, and returning to the step 102.
In this embodiment, in order to ensure the performance of the fixed terminal, the fixed terminal should avoid processing again after fetching data, and provide a plurality of data formats that meet the requirements of the front end as much as possible, for example: the data format of each data format comprises three-character codes, Chinese names, Chinese full spellings, Chinese simple spellings and the like of the sites.
The following describes, by way of simple example, various data formats:
total site data:
in the network ticketing system, the number of sites is very large, and because the data of all the sites, the data of popular sites and the data of letter classification sites have no dependency relationship, the three types of data can be generated by using three different threads, and finally, a complete JavaScript file is obtained by assembling.
The main code may be as follows:
it can be seen that the above method is used for obtaining the total site data assignment to arr [0], obtaining the popular site assignment to arr [1], obtaining the letter classification site assignment to arr [2], and finally splicing arr [0], arr [1] and arr [2] together to serve as the content of the JavaScript file by starting three different threads. The method can avoid the reprocessing after the fixed terminal acquires the latest station data, and can reduce the processing pressure of the fixed terminal.
When a mobile terminal, such as a mobile phone, is used to perform train ticket inquiry in a network ticketing system, data needs to be acquired from a mobile terminal side server, the mobile terminal side server needs to acquire all site data from a server side at regular time, and a time difference exists between the server side updating operation and the operation of acquiring all site data by the mobile terminal side server at regular time, and the two data are inconsistent in the time difference. Moreover, the number of stations is too large, but the number of stations changed each time is limited, and the possibility of transmission failure generally exists when the mobile terminal side server acquires all station data each time, which is long in time consumption and unstable in network.
For this reason, in the present invention, an improvement is made to a method for querying a train ticket by using a mobile terminal, and specifically refer to the flows shown in fig. 2 and fig. 3.
Referring to fig. 2, fig. 2 is a flowchart of a method for synchronizing data according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
In this embodiment, when the mobile terminal side server is online, all the site information is loaded and stored from the network ticketing system into the cache for storing the site information.
In this embodiment, the change type includes insertion, deletion, and modification. The latest site information transmitted from the server side to the mobile terminal side server in the network ticketing system includes only changed site information and does not include unchanged site information.
The method includes that a mobile terminal side server receives change site information which is sent by a server side in a network ticketing system and is bound with change types, and for each site change information, stored site information is updated based on the bound change types, and the method specifically includes the following steps: if the bound change type is insertion, directly storing the changed site information into a cache for storing the site information; if the bound change type is deletion, searching site information corresponding to the site change information in a cache for storing the site information, and deleting the searched site information; if the bound change type is modification, searching site information corresponding to the site change information in a cache for storing the site information, and covering the searched site information with the change site information.
Referring to fig. 3, fig. 3 is a flowchart of a data synchronization method according to an embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:
In the embodiment, the server side of the network ticketing system stores the site information by using a master database and a slave database, wherein the master database realizes synchronous data updating between the master database and the slave database by pushing a data updating log to the slave database. In addition, when the mobile terminal side server is on line, all site information is loaded and stored from the network ticketing system into a cache for storing the site information.
In this embodiment, the server at the mobile terminal may send a log pushing request to the master database, receive the data update log pushed by the master database, extract a log related to a change of the station information in the data update log, and if the log related to the change of the station information is extracted, determine that the station information at the server of the network ticketing system is changed, at this time, may analyze the extracted log to determine the station identifier and the change type of the changed station.
If the change type of a certain changed site extracted from the log by the mobile terminal side server is deleted, the site information corresponding to the changed site can be searched in the site information stored in the mobile terminal side server, and the searched site information is deleted. If the change type of a certain changed station extracted from the log by the mobile terminal side server is insertion or modification, the station identification of the changed station can be carried in the changed station information request and sent to the main database of the server side of the network ticketing system.
And step 302, the master database extracts the changed site information from the master database or the slave database as the latest site data according to the site identification of the changed site carried by the changed site information request, and sends the latest site data to the mobile terminal side server.
The latest site information transmitted from the master database to the mobile terminal side server includes only changed site information of which the change type is insertion and/or modification, does not include changed site information of which the change type is deletion, nor does it include unchanged site information.
In this embodiment, after the mobile terminal side server sends a request for changing site information to the master database and receives the latest site data returned by the master database, the stored site information may be updated based on the change type of each piece of changed site information in the latest site data, wherein when the change type of a changed site is an insertion, the changed site information may be directly stored in a cache for storing the site information; when the change type of the changed site is modified, the site information corresponding to the site change information can be searched in the cache for storing the site information, and the searched site information is covered by the changed site information.
As can be seen from the embodiments shown in fig. 2 and fig. 3, the server side of the network ticket-buying system only synchronizes the changed site information to the mobile terminal side server, so that on one hand, the synchronized data amount can be reduced, and the transmission failure rate caused by network instability can be reduced, and on the other hand, by the method of performing data synchronization immediately when the site is changed, the situation that the site data in the server side of the network ticket-buying system and the site data in the mobile terminal side server are inconsistent due to the time difference of acquiring all the site data regularly in the prior art is avoided.
