Fig. 4 is refer to, the method flow diagram of the data capture method provided it illustrates another embodiment of the present invention.This
Embodiment is main to be applied in the implementation environment shown in Fig. 1 illustrate with the data capture method.The data capture method,
Including：
Step 401, when first time obtaining target data, user end to server sends the first time for target data
Obtain request；
Target data is obtained for the first time and refers to client for the first time to the server lookup target data, such as client the
Once open a certain page and obtain data message on the page for the first time.Obtaining request for the first time is used to trigger server feedback
At least one renewal time point corresponding with target data.At least one renewal time point refers to that the client needs to update the mesh
The time point of data is marked, such as, a renewal time point is set every half an hour.
Step 402, server receives client and obtains request for the first time of target data；
It is that client is sent when obtaining target data for the first time to obtain request for the first time.When server receives the first time
It can be first time to server identification acquisition request, so that server learns that acquisition request is client when obtaining request
End provides renewal time point when obtaining request for the first time that target data is sent to client.
Step 403, server provides at least one renewal time point corresponding with target data to client；
Server is to client feedback at least one renewal time point corresponding with target data, and renewal time point is used to mark
Know the time that target data is modified in the server.Renewal time can also be made at least one renewal time point by server
List, to client feedback renewal time list corresponding with target data, the renewal time list includes at least one more
New time point.Server can also feed back simultaneously obtains the corresponding target data of request with the first time.
Step 404, at least one renewal time point corresponding with target data of client the reception server feedback.
Client obtains at least one renewal time point corresponding with target data from server and cached, renewal time point
For identifying the time that target data is modified in the server.If server feedback is renewal time list, client
Receive the renewal time list and cache.
The target data that client can be fed back with the reception server, can also record time when receiving the target data
Point, to judge whether to need to inquire about target data again to server using the time point later.
The step of above-mentioned first time acquisition target data for user end to server, when user end to server is obtained again
The target data namely when updating the target data, has the following steps：
Step 405, if target data had been obtained in this acquisition target data, when client detection is current
Between point the last time obtain time point between whether include renewal time point；
This had obtained target data and referred to before this acquisition target data when obtaining target data, client
The target data was obtained from server, this obtains target data namely obtains target data again, for updating
The target data got.
Current point in time refers to the time point of this acquisition target data of client.Acquisition time point the last time is nearest
The time point of target data is once obtained, namely refers to the time point recorded during client last time reception target data.During renewal
Between point refer to that the first time that client is sent in first time to server for target data obtains the renewal that receives after request
Time point.If client-cache is renewal time list, whether client can also be detected has in the renewal time list
Renewal time point fell between current point in time and the last acquisition time point.
Such as, it is assumed that current point in time is 00:12:00, acquisition time point the last time is 23:56:00, client-cache
There is renewal time point 22:00:00, renewal time point 22:30:00, renewal time point 23:00:00, renewal time point 23:30:
00, renewal time point 24:00:00, renewal time point 00:30:00, client detection current point in time 00:12:00 and nearest one
Secondary acquisition time point 23:56:Whether any one in above-mentioned 6 renewal time point is included between 00.
Step 406, if testing result is to include renewal time point between current point in time and the last acquisition time point,
Then user end to server sends the acquisition request for target data；
That is, client detects current point in time 00:12:00 obtains time point 23 with the last:56:Wrapped between 00
Point containing renewal time 24:00:00, then user end to server transmission is asked for the acquisition of target data.
Step 407, if testing result is not include renewal time between current point in time and the last acquisition time point
Point, then client calculate current point in time and the last time difference obtained between time point；
Namely do not fall within current point in time and the last renewal time point obtained between time point, such as, it is assumed that
Current point in time is 23:59:00, acquisition time point the last time is 23:35:00, then do not fall in above-mentioned 6 renewal times point
In current point in time and the last renewal time point obtained between time point.
Therefore, client is in order to further determine whether to need to obtain target data to server, and client calculates current
Time point 23:59:00 obtains time point 23 with the last:35:Time difference between 00 is 24 minutes.
Step 408, whether client detection time difference is more than scheduled update time interval；
Scheduled update time interval is predetermined in advance, and the scheduled update time interval is according to the actual conditions of target data
Set, for when point screening is inaccurate between when updated, carrying out judging whether to need to update target data again.
Such as, it is assumed that scheduled update time interval is set as 20 minutes.
Step 409, if testing result is the time difference to be more than or equal to scheduled update time interval, user end to server
The acquisition sent for target data is asked.
Such as, above-mentioned current point in time 23:59:00 obtains time point 23 with the last:35:24 minutes 00 time differences
More than scheduled update time interval 20 minutes, then the acquisition that user end to server is sent for target data was asked.
Step 410, server receives the acquisition request for coming from client for target data；
Because client had obtained target data, acquisition that this server is received request no longer needs mark the
Once, server need not provide renewal time point to client again.It should be added that, although server this be not required to
Renewal time point is provided to client again, but when the renewal time point for the target data changes, server
Or renewal time point can be provided to client, so that client upgrades in time.
Step 411, target data from server to client feedback；
Acquisition request is that client had obtained target data in this acquisition target data, and is detected current
Include what is sent after renewal time point between time point and the last acquisition time point；Or, it is client at this to obtain request
Target data had been obtained during secondary acquisition target data, and had been detected between current point in time and the last acquisition time point
Do not include renewal time point, but current point in time and the last time difference obtained between time point are more than the scheduled update time
Sent during interval.
Step 412, the target data of client the reception server feedback；
The target data that client has been got using the updating target data, to show newest target to user
Data.
Step 413, the time of this acquisition target data of client records, and update the last acquisition time point.
Such as, the time that client obtains target data is 00:12:00, then client is with time point 00:12:00 goes more
New the last acquisition time point 23:56:00, then acquisition time point the last time has reformed into 00:12:00.Work as client
It whether there is renewal time point between detection current point in time and the last acquisition time point again or calculate the time of the two
When poor, used the last acquisition time point is 00:12:00.
In summary, data capture method provided in an embodiment of the present invention, by being obtained and target data pair from server
At least one the renewal time point answered；If having obtained target data in this acquisition target data, detection is current
Whether include renewal time point between time point and the last acquisition time point；If testing result is current point in time and nearest
Renewal time point once is included between acquisition time point, then sends the acquisition request for target data to server；Solve
When client is again introduced into the page or returns to the page from other pages, client is required for again should to server lookup
Updating the data corresponding to the page, causes inquiry times excessively to bring larger pressure to server, causes flow to waste and take
The problem of Internet resources；Reach that reduction inquiry times alleviate the pressure of server, saved flow and reduce non-essential network
The effect of the occupancy of resource.
It should be added that, what above-mentioned steps 401 were related into step 404 simply obtains number of targets in first time
According to when, the first time that user end to server is sent for target data obtains the situation of request, in addition, client is except the
Obtained when once obtaining target data to server outside at least one renewal time point, client is obtaining target in first time
Before data, after first time acquisition target data（Namely to server obtain target data during）Though or client
So warp-wise server obtained target data, but client, when locally not caching the target data, client can also
At least one renewal time point is obtained from server, therefore the acquisition time of at least one renewal time point does not limit.Furthermore,
When the renewal time point on server for target data changes, server can also update to server feedback at any time
Renewal time point afterwards, so that client obtains newest renewal time point.Supplementary notes are also needed to, server is according to extremely
The renewal time list that a few renewal time point is made can be set for target data or general, depending on tool
Depending on body situation.
