step 1, checking whether the obtained identifier of the local picture is the same as the identifier in the request or not; and if the local pictures are the same, executing the operation of displaying the thumbnail of the local picture in the network disk application program. That is, whether the identifier of the local picture locally acquired from the client is the same as the identifier in the request is checked, so that the picture locally acquired from the client is prevented from being modified, and the modified picture is taken as the target picture.
Step 2, judging whether the backup time is behind the generation time of the local picture; and if so, executing the operation of displaying the thumbnail of the local picture in the network disk application program. The backup time in the request may be system time when the client finishes uploading the local picture to the server. The system time may be a system time common to the client and the server. And if the backup time is before the generation time of the client local picture or the backup time is the same as the generation time of the client local picture, determining that the client local picture is not the target picture.
Step 3, judging whether the type is the same as that of the local picture; and if the local pictures are the same, executing the operation of displaying the thumbnail of the local picture in the network disk application program. Common picture types include jpg, png, and so on. And if the picture type in the request is different from the type of the local picture of the client, determining that the local picture of the client is not the target picture.
If the request also includes the capacity of the picture, whether the capacity in the request is the same as the capacity of the local picture of the client or not can be further judged, and if the capacity is the same, the local picture of the client can be further determined to be the target picture.
