Description
Technical Field
The invention relates to the field of intelligent televisions, in particular to an efficient downloading method of information on shelves of an intelligent television application store.
Background
The intelligent televisions are all provided with corresponding application stores to serve users, and are mainly used for downloading applications which are strong in weather, live broadcast and the like, high in user downloading rate and free of preset. Some of these applications are applications that many users want to use, such as live tv, to help users watch tv programs. In order to facilitate user operation, a system name is often triggered by a condition to help a user actively pull up installation of a third-party application in a background, for example, when the user calls a television station name by voice, similar to 'CCTV 1', the voice actively initiates a live broadcast application on-shelf information query to a store, the store queries that a corresponding application is on-shelf, then pulls up a download link of the live broadcast application through the store, and after downloading and installation are successful, the user can use the live broadcast application to watch live programs such as CCTV1 and the like.
the function provides convenient digital television service for users, after the live television is online, a small-probability prompt appears after a small number of machines in the market call the station, and the live television cannot be switched to a designated station. From logs and experiments, this probabilistic parsing of the cause of the anomaly is:
In order to ensure the timeliness of application information, the application logic needs that after a client is started, all application information of a store is acquired from a server of the application store once, and then the subsequent downloading of live applications such as store application of a start guide and voice pull-up HDP (high-level personal profile) can be executed.
But when the client side obtains the information on the shelf of the server side application: on one hand, in order to ensure data updating of an application store, a client needs to synchronously download dozens of megabits of files from a cloud end to the local area every time the application or the startup is carried out, the downloading frequency is too high, and whether errors occur in downloaded data cannot be ensured; on the other hand, the server load pressure of the application store is too heavy: with the increase of time and scale, the number of applications carried by a shop is increased, and each application contains a lot of data, so that the application information file (json file) is also increased. If the Json file is too large, each client side can inquire the server every time when being started, and the occupied I/O interface information is too large, so that the reading performance of the server is seriously reduced; when encountering simultaneous or frequent downloads from multiple clients, server stress can trigger an exception, and even if the request is successful, the JSON returned may be "null". And the logic for subsequently calling the shop application cannot be normally executed due to the abnormal application information data. Therefore, there is a need to improve the efficiency of querying for application store on-shelf information for such unreliable data results.
Disclosure of Invention
The invention aims to provide an efficient downloading method of information on shelves of an intelligent television application store, which is used for solving the problem that data information is wrong when the data is read and downloaded due to the fact that the data amount is increased in the prior art.
the invention solves the problems through the following technical scheme:
a method for efficiently downloading information on shelves of an intelligent television application store comprises the following steps:
step 1: when the television is started, the client application store inquires the latest modification time of the application information file from the server;
Step 2: comparing the latest modification time obtained in the step 1 with the last modification time, and if the two times are consistent, not downloading the application information file; and if the data are not consistent, downloading the application information data.
By the method, json files of application store on-shelf application information do not need to be downloaded after the system is started every time, and the problem that a plurality of clients of the server download at the same time is solved; if a common television user watches live television 7 days a week, if the television user is started up 2 times a day, if a shop updates an application once a week, a single machine in the prior art submits a download request to a server for at least 14 times a week; using this method reduces to 1 download per week. In comparison, the downloading request received by the shop server is reduced with high probability, and the problems that the server system load is too high and the data downloading is wrong due to too many tasks triggered and operated by the server at the same time are avoided.
Preferably, in step 1, the server is queried by using the HEAD method, so as to obtain the modification time of the current application on-shelf information file of the server.
preferably, the HEAD is configured with an update date or MD5 code.
Preferably, in the step 2, when the latest modification time is inconsistent with the last modification time, the asynchronous downloading is automatically performed in the background.
preferably, the latest modification time is the last modification time of a file on the server, and the last modification time is the last modification time of the json file of the application listing information cached by the client.
preferably, in step 2, after receiving the downloaded application information data, the client overwrites the old file with the new file, and caches the old file at the original path address.
Preferably, in step 2, when the times are consistent, the server returns 304 codes.
compared with the prior art, the invention has the following advantages and beneficial effects:
The access times and frequency of the smart television client to the application market server are reduced, the application information data are not required to be downloaded when the television is started at every time, the situations that the server system is too high in load and data downloading is wrong due to too many tasks of the server which simultaneously triggers running are avoided, and the problems in the prior art are well solved.
Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
When encountering simultaneous or frequent downloads from multiple clients, server overstress triggers an exception, and even if the request is successful, the returned JSON may be "null", and the request process is as follows:
Therefore, the method for efficiently downloading the information on shelves in the smart television application store is provided, and comprises the following steps:
Firstly, inquiring change time variation of an on-shelf application information file:
and sending the last modification time of the json file with the application information cached by the client to the server by using a HEAD method, and comparing the time with the last modification time of the actual file on the server by the server. If the time is consistent, return 304, meaning unmodified (Not Modified), the client uses the local cache file directly and no longer downloads. If the time does not coincide, 200 (request success) and new file content, request will be returned
For example:
Parameters to set HEAD when requesting dl-appstore.
If-Modified-Since：Mon,17 Aug 201912:03:33 GMT
Host：appstore.Huan.com
If the part of the request is modified after the specified time, the request is successful and the download is carried out again; unmodified, the code is returned 304.
Then, after receiving the new file, the client overwrites the old file with the new file, and caches the new file at the original path address:
for example, the application listing information file CH-ZLS82Gi-DTV-00-icntv.json of the application store of 848 deck covers the same-name file under the original./appstore/files, and the content of the latest modification time requested to the server application listing information file is specifically shown in the following table:
finally, if a voice command is received, the on shelf status is queried hdp:
Searching the current application according to the package name, and directly pulling up the current application if the current application is locally installed;
If the local download link is not installed, acquiring the corresponding download link in the application loading information cached locally according to the application package name (packageName);
the information on shelves fed back by the shop contains a download path of a designated application App:
"fileUrl":
https://dl-appstore.huan.tv//appstore/resources/2015/01/08/b6c41381994340898419dab02a345277/CH/app_1563346005240.cha/appid＝hdpfans
the above example is the downloading and calling of the application loading information of the television core CH-ZLS82Gi-DTV-00-ICNTV, and the specific contents are as follows:
"apkpkgname":"hdpfans.com",
"appid":"b6c41381994340898419dab02a345277",
