Technical Field
The invention belongs to the technical field of networks, and particularly relates to a method for guaranteeing the validity of building information retrieval of mobile equipment.
Background
At present, the search of the building through the APP (such as shell house finding APP, resident guest living, new house living APP and the like) of the building retrieval is a common building search method, and cloud data is acquired in real time through a network request on a mobile device. Because the data volume of the building is huge, the satisfactory retrieval efficiency can be obtained only by depending on a strong network environment. If the network environment is poor or no network exists, the data cannot be acquired, and the APP cannot be normally used. Therefore, the use of the user in the actual watching mode is seriously influenced, the use scene of the user cannot be met, and the user experience is influenced.
Currently, in the sales activities of the house sales intermediaries, sales personnel can often bring customers to suburbs to visit the buildings, and the network environment is not good in such places, so that the customers cannot quickly search the buildings and display the buildings. In order to solve the problem, in the prior art, a network caching mode is tried, but only the requested floor is cached, and the limitation is limited, so that the normal use of the floor with watching is not satisfied. There have also been solutions that use local caching of databases, but more complex data volume and data security issues need to be addressed.
How to rapidly retrieve the building under the weak network environment, ensure the safety of the data and ensure the relative real-time performance of the data is the problem to be solved.
Disclosure of Invention
In order to solve the above problems, the present invention provides a method for guaranteeing the validity of the building information retrieval of a mobile device, wherein a building information retrieval APP runs in the mobile device, and the method comprises the following steps:

encrypting a process of downloading a database file by the mobile equipment;
and (3) forcibly or automatically updating the local database file of the mobile equipment.
Further, after the mobile device logs in the APP, according to the network condition and the current status of the local database, the process of updating or downloading the database file specifically includes:
if the network intensity meets the minimum requirement, checking whether the offline data needs to be updated, and if so, downloading and decompressing the database file; if the local database does not need to be updated, judging whether the local database exists, and if the local database does not exist, downloading a new database file;
and if the network state cannot meet the requirement of the minimum network intensity, checking whether the local database file exists, and if not, prompting a user to use a building to retrieve the APP after downloading the database file.
Further, the process of encrypting the database file downloaded by the mobile device specifically includes: and encrypting all the data tables of the downloaded database file by using sqlcilpher, and deleting the originally downloaded file after encryption is finished.
Further, in the process of encrypting the database file downloaded by the mobile device, if the downloaded database file is not encrypted, all the database files are deleted, and the user is prompted to download the database file again.
Furthermore, in the process of automatically updating the local database file of the mobile device, the execution time of the process of automatically updating the database file is preset time, when the preset time is reached, the building retrieval APP does not operate or the network strength meets the minimum requirement, forced updating is not executed, and when the APP starts to operate and the network strength meets the minimum requirement, the forced updating is executed again.
Further, in the process of forcibly updating the local database file of the mobile device, the conditions for the forced updating are as follows: urgent data in the existing local database file needs to be repaired or the version of the building information retrieval APP is updated.
Further, the method further comprises a process that the cloud server associates the database file with the version number of the corresponding APP.
Further, the format of the database file packaged by the cloud server is db.
The invention has the beneficial effects that:
the invention solves the problem that the house source search can not be normally carried out when the network environment is not good; the problem of huge data volume storage is solved by a mode of distributing compressed data files in different cities; the data safety is ensured by encrypting the data table; the relative real-time performance of the data and the robustness of the data are solved through a strong updating mechanism (the local database file is deleted or the content is adjusted, the database file needs to be forcibly updated) and a weak updating mechanism (the local database file exists and is currently in a non-network environment or does not respond within 3 seconds when requested by the network environment). Therefore, the use experience of the user is improved, the safety of data is guaranteed, and the worry of the APP user is solved.
Detailed Description
The method for guaranteeing the effectiveness of the building information retrieval is suitable for common mobile terminals, such as mobile phones, IPADs and the like, and the APP for building retrieval (which can be a common house source retrieval APP in the market at present) runs in the mobile equipment.
The method comprises the following steps.
The first process is as follows: and logging in the building to retrieve the APP.
The method is suitable for the current common building retrieval APP on the market.
And the cloud server packs database files in cities according to the login account number through scripts. When the account is not logged in, the method has a process of prompting to register, and the registration process is the same as the common APP registration process and is not described herein again.
And a second process: and the cloud server packs the database files into database files (the format of the database files is db) which can be directly accessed by the mobile equipment by the scripts in cities according to the information of the login account, and compresses and encrypts the database files.
The database file contains the information of the buildings of the city where the user is located (such as the source of the selling house, the unit price of the source of the house, the house type, the traffic condition, the dynamic state of the buildings, the time of first delivery and the like), and preferably also includes the information of the city (such as the economic condition, the population condition, the enterprise condition, the development policy and the like of Beijing city). The technical means of obtaining the city of the user, compressing and encrypting is to adopt the prior art.
And a third process: after the mobile device logs in the APP, updating or downloading the database file according to the network condition and the current situation of the local database.
For the mobile device that has logged in, it is determined whether the current network environment is good, and if the current network environment can meet the minimum requirement (in this embodiment, the minimum requirement means that a response is made within 3 seconds of initiating the request, and in practice, the minimum requirement may be set as needed), it is checked whether the offline data needs to be updated. Generally, if the current database version is not the latest version, the offline data needs to be updated.
If the update is needed, the mobile device downloads the database file containing the corresponding city house source information, decompresses and encrypts the database file, and then can access the database to display the data. If the database file does not need to be updated, in order to avoid that the user deletes the local database file by mistake, whether the local database file exists or not is judged, if the local database file does not exist, the new database file still needs to be downloaded, and then decompression and encryption are carried out.
If the network environment is not good, whether a local database file exists or not needs to be checked, if yes, the file is used, and if not, a prompt pops up to inform a user that the database file needs to be downloaded when the network environment is good so that the APP can be used. Therefore, when no network exists or the network environment is not good, the function of the APP normally used by the user is not influenced.
And (4) a fourth process: and encrypting the process of downloading the database file by the mobile equipment.
The process of encrypting the database file specifically comprises the following steps: and encrypting all data tables of the database files downloaded by the mobile equipment by using sqlcilpher, and deleting the originally downloaded files after encryption is finished. If the encryption fails, all database files are deleted, and the user is prompted to download the database files again. Therefore, only the encrypted database file is visible to a user, the database file can be accessed only by using the password when being accessed, and the database file cannot be opened by a tool even if the database file is intercepted from the outside. Thus, the data security is ensured.
And a fifth process: and (3) forcibly or automatically updating the local database file of the mobile equipment.
In order to ensure the relative real-time performance of data and the necessity of data updating, the invention sets a database file updating mechanism.
The automatic update will be explained first.
And automatically updating the database at regular time by the database file, and when the floor retrieval APP does not operate or the network strength meets the minimum requirement, not executing the database file, and waiting for the APP to allow and the network strength to meet the minimum requirement.
For example: setting a time (such as 2 am every day), if the APP is still alive, the APP will actively update the database file; if the APP does not survive, the database file is updated when the APP is started for the first time every day and in the case of a good network environment.
Forced updating is described next.
Forced updates are generally divided into two cases:
1. if urgent data in the existing local database file needs to be repaired, a process of forcibly updating the database file needs to be executed, and the user is forcibly required to update when starting the APP by manually updating script data.
2. When the version of the APP is updated every time, in order to ensure the robustness of data, the database file is associated with the version number of the APP, and a user is forced to download the database file of the corresponding version, so that the APP can be accessed.
Through the technical scheme, under the condition that the network environment is not good or the condition that the network does not exist, as long as the database file of the cloud side is downloaded locally, the building retrieval and the building display in the APP can be carried out without depending on the network, so that a user can normally use the APP in a place with a poor network.
It should be noted that, as those skilled in the art will understand, the above-mentioned each process is not limited to the execution sequence of the steps, and the execution sequence of each process may be combined and executed as needed for achieving the purpose of normally retrieving the house source information in the weak network scenario.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited to the above embodiments, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all those persons skilled in the art should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
