Description
Technical field
The present invention relates to the communications field more particularly to a kind of set-top box JSON data parsing storage methods and system.
Background technology
JSON formats are mainly used for transmitting data, use and be completely independent as a kind of data interchange format of lightweight
In the text formatting of language, indicated in JavaScript object one group of data can be converted to character string, then
This character string is easily transmitted between function, or passes to character string from Web client in asynchronous application
Server.JavaScript is easily explained JSON, and JSON can indicate the knot more more complicated than " name/value to "
Structure, these characteristics make JSON become ideal data interchange language, are easy to read and write, while being also easy to parse and generate.
In set-top box application, JSON data are often obtained from remote server.In order to avoid JSON data are anti-
Multiple parsing, it will usually JSON data be parsed and store set top box side.But in set top box side parsing JSON data storage
In the process, it can cause JSON data can not be after because of certain reasons (such as set top box side or server end abnormal, Network Abnormal)
It is continuous to parse and store, to destroy the integrality of JSON data.In order to ensure that the integrality of JSON data, traditional method are to work as
When occurring abnormal, notice parses and stores JSON data again, and this mode needs to handle it to each extremely, cost compared with
Height, and need all to parse storage data again, efficiency is relatively low, is unfavorable for the parsing of JSON data significantly.

S10：When parsing JSON data, the data list of JSON data is obtained, JSON data are obtained by data list
Total item and stored；
S20：Installation position records, for after each single item JSON data are all parsed and preserved, recording global solution
The item number N of JSON data for analysing and preserving；
S30：The item number N that position records is compared with total item, if the item number N of position record is less than total item,
N+1 JSON data are removed, and parses and is stored again by N+1 JSON data, until position record
Item number is identical as total item.
In further mode, the step S30 further includes：
When being parsed to current JSON data, whether there is version number before detection, if there is no if explanation be the
Current JSON data are then re-started parsing and stored by one parsing, and if it exists, the version number before then obtaining.
In further mode, the step S30 further includes：
The version number of current JSON data is obtained, and is compared with version number before, if inconsistent, current JSON
Data are all parsed and are stored, and are updated；If consistent, the item number N that position records is compared with total item.
In further mode, the step S30 is specially：
If the item number N of position record is less than total item, when containing the path for being directed toward another JSON data in JSON data, then
N+1 item datas are removed, and remove another JSON data of N+1 directions, are parsed simultaneously since N+1 item datas again
Storage, while another JSON data of N+1 directions are parsed and stored again.
The present invention also provides a kind of set-top box JSON data analysis storage systems, including：
Total item acquiring unit obtains the data list of JSON data, is obtained by data list when parsing JSON data
It takes the total item of JSON data and is stored；
Position recording unit, installation position record, for after each single item JSON data are all parsed and preserved, record to be
The item number N of JSON data through completely parsing and preserving；
Storage unit is parsed, the item number N that position records is compared with total item, if the item number N of position record is less than
Total item then removes N+1 JSON data, and parses and stored again by N+1 JSON data, until position
The item number for setting record is identical as total item.
In further mode, the parsing storage unit is when parsing current JSON data, before detection
With the presence or absence of version number, it is to parse for the first time if illustrating there is no if, current JSON data is re-started into parsing and are stored,
If in the presence of the version number before obtaining.
In further mode, the parsing storage unit obtains the version numbers of current JSON data, and with before
Version number is compared, if inconsistent, current JSON data are all parsed and stored, and are updated；It, will if consistent
The item number N of position record is compared with total item.
In further mode, if the item number N of position record is less than total item, it is another to contain direction in JSON data
When the path of JSON data, the parsing storage unit then removes N+1 item datas, and N+1 directions of removing is another
JSON data, parse and store since N+1 item datas again, at the same parse again and store N+1 direction it is another
JSON data.

Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
Fig. 1 is the flow chart of the set-top box JSON data parsing storage method in one embodiment, as shown in Figure 1, the party
Method includes the following steps：
S10：When parsing JSON data, the data list of JSON data is obtained, JSON data are obtained by data list
Total item and stored.
In set-top box in JSON data resolvings, set-top box being caused completely can not to parse and store the different of JSON data
Often there are many reasons, each exception set-top box are required for parsing storage JSON data again, this will result in cost and effect
The problem of rate.To avoid this problem, in the embodiment, since when being abnormal, set-top box may have been parsed and stored
Part JSON data, therefore position record can be carried out to the JSON data for having parsed storage, need not go again parsing and
Store all JSON data.Specifically, for can JSON data be carried out with position record, the step is in parsing JSON data
When, the data list of JSON data is obtained first, and the total item of JSON data is then obtained by data list and is stored,
The total length of JSON data is obtained in this way.
S20：Installation position records, for after each single item JSON data are all parsed and preserved, recording global solution
The item number N of JSON data for analysing and preserving.
After obtaining the total length of total item namely JSON data of JSON data, installation position record, position record is used
After all parsing and preserving in each single item JSON data, the item number N for completely having parsed and having stored is recorded, position is recorded in often
Parsing updates once after having stored a JSON data, i.e., the item number recorded is added 1, can thus be deposited in real time to having parsed
The JSON data of storage are positioned.
S30：The item number N that position records is compared with total item, if the item number N of position record is less than total item,
N+1 JSON data are removed, and parses and is stored again by N+1 JSON data, until position record
Item number is identical as total item.
After the item number N for the JSON data that record has completely been parsed and preserved, by by recorded item number N and always
Item number is compared, it will be able to know whether JSON data all parse and stored.If the item number N of position record is less than total item
Number, then illustrate that JSON data are not all parsed and stored, and is abnormal when parsing and storing N+1 JSON data,
N+1 JSON data are not parsed and have been stored, due to being recorded to the position being abnormal, then by N+1
Item JSON data start to parse and be stored, until the item number of position record is identical as total item, thus substantially increase
The efficiency of JSON data parsing storage, greatly reduces cost.
Further, since have corresponding version in JSON data, the JSON versions of data differences of different editions, for not
With the JSON data of version number, need all to carry out parsing and storing again, therefore the step further includes：To current JSON data
It when being parsed, whether there is version number before detection, be to parse for the first time if illustrating there is no if, by current JSON data
It re-starts parsing and stores, and if it exists, the version number before then obtaining.
Further, the version number of current JSON data is obtained, and is compared with version number before, if differing
It causes, then current JSON data are all parsed and stored, and are updated；If consistent, by the item number N of position record and total item
Number is compared.
Simultaneously as the value of JSON data each single item contents can be arbitrary string, which is possible to indicate to refer to
To the path of another JSON data, need to parse another JSON data by the path.In this embodiment, if position record
Item number N is less than total item and then removes N+1 item datas when containing the path for being directed toward another JSON data in JSON data, and
Another JSON data for removing N+1 directions, parse and store since N+1 item datas again, while parsing again simultaneously
Store another JSON data of N+1 directions.
Set-top box JSON data parse storage method, obtain JSON data total item, and in real time to JSON data into
Line position sets record, and the position of record is compared with total item, if the position of record is less than total item, by N+1 JSON
Data start to parse and stored again, and JSON data are parsed and stored by positioning the position being abnormal,
Need not all JSON data be parsed and be stored, to substantially increase the efficiency of JSON data parsing storage, significantly
Reduce cost.
Meanwhile the present invention also provides a kind of set-top box JSON data analysis storage systems, as shown in Fig. 2, the system includes：
Total item acquiring unit 100 obtains the data list of JSON data, is arranged by data when parsing JSON data
Table obtains the total item of JSON data and is stored.
In set-top box in JSON data resolvings, set-top box being caused completely can not to parse and store the different of JSON data
Often there are many reasons, each exception set-top box are required for parsing storage JSON data again, this will result in cost and effect
The problem of rate.To avoid this problem, in the embodiment, since when being abnormal, set-top box may have been parsed and stored
Part JSON data, therefore position record can be carried out to the JSON data for having parsed storage, need not go again parsing and
Store all JSON data.Specifically, for position record, when parsing JSON data, total item can be carried out to JSON data
Number acquiring unit 100 obtains the data list of JSON data first, and the total item of JSON data is then obtained by data list
And stored, the total length of JSON data is obtained in this way.
Position recording unit 200, installation position record, for after each single item JSON data are all parsed and preserved, remembering
Record the item number N for the JSON data for completely having parsed and having preserved.
After obtaining the total length of total item namely JSON data of JSON data, 200 installation position of position recording unit
Record, position record is for after each single item JSON data are all parsed and preserved, recording the item for completely having parsed and having stored
Number N, position, which is recorded in after every parsing has stored a JSON data, to be updated once, i.e., the item number recorded is added 1, thus can
The JSON data for having parsed storage are positioned in real time.
Storage unit 300 is parsed, the item number N that position records is compared with total item, if the item number N of position record is small
In total item, then N+1 JSON data are removed, and parse and stored again by N+1 JSON data, until
The item number of position record is identical as total item.
After the item number N of JSON data that record has completely been parsed and preserved, parsing storage unit 300 is by will
The item number N of record is compared with total item, it will be able to know whether JSON data all parse and stored.If position records
Item number N be less than total item, then illustrate that JSON data are not all parsed and stored, parse and store N+1 JSON
It is abnormal when data, N+1 JSON data are not parsed and stored, due to being carried out to the position being abnormal
Record, parsing storage unit 300 are then parsed and are stored by N+1 JSON data, until the item number of position record
It is identical as total item, the efficiency of JSON data parsing storage is thus substantially increased, cost is greatly reduced.
Further, since have corresponding version in JSON data, the JSON versions of data differences of different editions, for not
With the JSON data of version number, needs all to carry out parsing and storing again, therefore parse storage unit 300 to current JSON numbers
It when according to being parsed, whether there is version number before detection, being to parse for the first time if illustrating there is no if, by current JSON numbers
According to re-starting parsing and store, and if it exists, the version number before then obtaining.
Further, parsing storage unit 300 obtains the version numbers of current JSON data, and with version number before into
Row compares, if inconsistent, current JSON data are all parsed and stored, and are updated；If consistent, position is recorded
Item number N be compared with total item.
Simultaneously as the value of JSON data each single item contents can be arbitrary string, which is possible to indicate to refer to
To the path of another JSON data, need to parse another JSON data by the path.In this embodiment, if position record
Item number N is less than total item, and when containing the path for being directed toward another JSON data in JSON data, parsing storage unit 300 is then removed
N+1 item datas, and another JSON data of N+1 directions are removed, it parses and deposits since N+1 item datas again
Storage, while another JSON data of N+1 directions are parsed and stored again.
Set-top box JSON data analysis storage systems, obtain JSON data total item, and in real time to JSON data into
Line position sets record, and the position of record is compared with total item, if the position of record is less than total item, by N+1 JSON
Data start to parse and stored again, and JSON data are parsed and stored by positioning the position being abnormal,
Need not all JSON data be parsed and be stored, to substantially increase the efficiency of JSON data parsing storage, significantly
Reduce cost.
Set-top box JSON data parsing storage method and system of the present invention, obtain the total item of JSON data, and right in real time
JSON data carry out position record, and the position of record is compared with total item, if the position of record less than total item, by the
N+1 JSON data start to parse and stored again, are solved to JSON data by positioning the position being abnormal
Analysis and storage, all JSON data need not be parsed and be stored, to substantially increase the parsing storage of JSON data
Efficiency greatly reduces cost.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
