If 104, not finding the mark of client in history identification, target is determined in the data to be selected of data resource Data, wherein data to be selected are the data that do not downloaded by any client according to two dimensional code in data resource.
If not finding the mark of the client in history identification, it is determined that the client is for the first time according under the two dimensional code The data in data resource are carried, are allowed to its returned data.
Data download apparatus can be determined in data resource and be downloaded according to the two dimensional code according to history Download History Then the data configuration that do not downloaded according to the two dimensional code in data resource is data to be selected by the data crossed.
Then, data download apparatus can using in data to be selected partial data or total data as target data, use To return to the client.
Specifically, in some embodiments, data resource may be file set, including more parts of data files.If then data Resource includes more parts of data files, then step " target data is determined in the data to be selected of data resource " may include: more The data file that do not downloaded by any client according to two dimensional code is filtered out in part data file, as data to be selected；According to Preset rules select one or more parts data file as target data in data to be selected.
For example, the two dimensional code unique identifier carried in the available access request of data download apparatus, according under history Record is recorded, the data file downloaded by other clients according to the two dimensional code in data resource is searched, thus in data The data file that do not downloaded by any client according to the two dimensional code is filtered out in resource, as data to be selected.
Then, data download apparatus selects one or more parts data file work according to default rule in data to be selected For target data.Wherein, default rule can be quantity rule, for example, selecting preset quantity in data to be selected every time Data file, as target data.Wherein, preset quantity can be 1 or 2 etc., specifically can flexible configuration according to actual needs.
In some embodiments, the step mark of client " in history identification search " if after can also include: The mark of client is found in history identification, then the whole of data resource data to be selected is returned into client, or, not to client Any data in returned data resource.
If not finding the mark of the client in history expression, it is determined that the client is not for the first time according to the two dimensional code Data in downloading data resource.
As an implementation, data download apparatus thinks that the client needs whole numbers in downloading data resource According to then the whole data to be selected in data resource being returned to the client.
As another embodiment, data download apparatus does not return to different data to same client, then can look into Historical record is ask, the data for once returning to the client are sent once to the client again, client last downloaded is avoided to lose Data resource caused by situations such as losing is not downloaded completely.
As another embodiment, data download apparatus can also be not responding to the access request of the client, not to this Any data in client returned data resource.It is, of course, also possible to return to notification message to client, the client has been notified Through downloading the data in this data resource.
105, target data is returned into client.
After determining target data, target data is returned to client by data download apparatus, under the difference for realizing data It carries.
From the foregoing, it will be observed that the intermediary that the program downloads two dimensional code as data, also, quickly distinguished by client identification Different clients, to realize the orderly access of data resource in server-side, server-side can perceive each client access The timing of request, so as to effectively allow server-side decision to there emerged a which portion of which file of client downloads or file Point, so that multiple client can orderly download the different data in same data resource according to two dimensional code, realize number According to difference downloading.Client quickly can return to the different fragments of same file or same to each client respectively as a result, Different files in one file set no longer need to the data for expending time verification client local, and accordingly, multiple client can be with The different files that the different fragments or same file for downloading same file respectively are concentrated, without expend a large amount of flow go from Client downloads partial data improves the efficiency of data downloading by difference downloading.In addition, subsequent, this multiple client can To share the file in the file fragment respectively downloaded or file set mutually, to take complete data resource.
