Content based on the above embodiment, as a kind of alternative embodiment, the embodiment of the present invention is not based on mobile terminal
To the scanning result of every image in 2 D code, the mode for obtaining target data is specifically limited, including but not limited to: mobile terminal
According to the checking mark in the scanning result of every image in 2 D code, every group in the scanning result of every image in 2 D code is judged
Whether data meet preset condition；If every group of data in the scanning result of every image in 2 D code meet preset condition, move
Dynamic terminal is spliced, decrypted and is decompressed to every group of data in the scanning result of every image in 2 D code, and number of targets is obtained
According to.
It should be noted that can be spliced in order according to grouping label, this hair when splicing to every group of data
Bright embodiment is to this insufficient specific restriction.It should also be noted that, above-mentioned can be mobile whole to the process of every group of data splicing
End side executes, and the process decrypted and decompressed can be executed in mobile terminal side, after can also being spliced by mobile terminal
The data back arrived executes the process of decryption and decompression to server, and in server side, and the embodiment of the present invention does not make this
It is specific to limit.
Content based on the above embodiment, as a kind of alternative embodiment, preset condition is sweeping for every image in 2 D code
Retouch that every group of data in result are complete and the corresponding several groups data of all scanning results are complete.
Specifically, one image in 2 D code of the every scanning of mobile terminal, available scanning result, the scanning result
In include the checking mark before one group of data and this group of data.It, can according to the grouping label and total number packets in checking mark
It is whether complete with the corresponding several groups data of all scanning results of determination.According to the timestamp of checking mark, it can be determined that every group
Whether data are effective.In addition, being isolated if every group of data in the scanning result of every image in 2 D code are unsatisfactory for preset condition
System recompiles target data in netting, and regenerates several image in 2 D code, and mobile terminal can also be again
Image is scanned the two-dimensional code, namely re-executes process above.
