Specific embodiment
Below in conjunction with attached drawing and specific embodiment, technical scheme of the present invention is described in detail.
Fig. 1 is in the flow chart of client-side, method packet the present invention is based on the network data synchronizing method of operational order
It includes：S101 operational order download steps after client logs in, are instructed from server-side down operation；S102 data synchronizing steps, needle
To the local file or catalogue of client, the operational order of download is performed, carries out the synchronization of local data.
Wherein, the operational order of server-side is corresponding to the modification operation of file in client with user, moreover, user can
Client is logged in using different equipment（Such as smart mobile phone client, laptop client etc.）To interested file
Or catalogue carries out additions and deletions and the modifications operation such as changes, it is each operate successfully after, will all generate corresponding operates in server-side and refer to
It enables.
Correspondingly, in server-side side, after client logs in, server-side issues operational order to it.
In practical application scene, based on Dropbox（Also referred to as network hard disc）, the technologies such as cloud storage network data storage
The files through network of oneself is uploaded to server-side and stored by function, user, when needing to check, change, by computer, flat
Panel device or smart mobile phone etc. log in client.The present embodiment logs in client using mobile phone, using Dropbox as the service of server-side
Device.
To ensure that the data that user sees are consistent with the data stored in current Dropbox, after mobile phone logs in client, first
Operational order is downloaded from Dropbox.
These operational orders have recorded the past period user（This user or other users）On the client to file
Whole modification operations that data carry out.For example, party a subscriber logged in client before three days by mobile phone, and A files are carried out
Renaming is to receive the request of client renaming in the processing of Dropbox server-side, and after renaming operate successfully, server-side is given birth to
" renaming " operational order for being directed to A files into one；Party b subscriber was logged in before two days by computer, by B files from the first mesh
Record has been moved under the second catalogue, and " movement " operational order for being directed to B files is generated in server-side.Similarly, according to
The data manipulation of user on the client, server-side can also generate for file or folder " newly-built " operational order and " delete
Except " operational order, if client has recycle bin function, it can also generate " recycling " operational order, etc..
After cell-phone customer terminal downloads to operational order, it is possible to for local file or file, perform these behaviour
It instructs, that is, according to " renaming " operational order for being directed to A files, to local A files renaming, according to for B
" movement " operational order of file, B files are moved to from the first current catalogue under the second catalogue, etc..So as to mobile phone
The data of client are carried out with new, and realization cell-phone customer terminal is synchronous with network disk data.
Above-mentioned method of data synchronization is only needed when synchronous using the concrete operations of operational order record user for occurring
Operation carry out local corresponding operating.It does not need to download whole user file from Dropbox when carrying out data synchronization using the above method
Tree, so also without carry out file tree comparison, reduce network data transmission amount, reduce network data processing amount, can
System resource is saved, alleviates system pressure.
In addition, in the above-described embodiments, if this login is first logged into using the mobile phone, directly by all files
It is locally downloading with bibliographic structure etc., it carries out instructing download synchronous with data in follow-up log on.
In one embodiment of the invention, for ease of processing, the operational order of server-side generation carries timestamp.About
Timestamp, in general, timestamp（Timestamp）Finger adds in time identifier in data, such as date or moment, weight in record material
The time of origin of event is wanted, can ensure that local data updating sequence is consistent with distal end, can be provided on the time for data management from now on
Identification.
In one embodiment of the invention, party a subscriber has done renaming operation in cell-phone customer terminal to A files（Or it moves
Dynamic operation etc.）, after having spent a period of time, party a subscriber has carried out delete operation to A files again.Party b subscriber is stepped on computer after then
After record, according to the timestamp of operational order, last delete operation instruction need to be only received, directly deletes A files, it can
Data processing amount is reduced to a greater degree, saves system resource.
In above example, in order to record all operations of user, all operational orders that server-side generates need to all be protected
Presence service end is used for each client downloads.
In order to reduce the quantity of server-side operational order, in one embodiment of the invention, during according to the login of user
Between data synchronization processing mode is set, do not need to preserve all operational orders in server-side, only preserve a period of time recently（Such as
One month, two months, half a year or a longer period of time）Within operational order, specific processing mode can be divided into following several situations：
First, the operational order within such as one month is preserved if presetting server-side, when client sheet
When the time of secondary login time distance subsynchronous data thereon is such as three weeks, then the timestamp based on operational order, client
The operational order generated in this three weeks is only downloaded from server-side, remaining instruction is not downloaded.
Second, the operational order within such as one month is preserved if presetting server-side, when client sheet
When time of the secondary login time apart from subsynchronous data thereon is such as two months, then before any operational order is downloaded, visitor
Family end first uploads itself current file tree to server-side, and server-side receives client file tree, and by this document tree with servicing
The file at end is compared, it is therefore an objective to create operational order according to the difference of two file trees.Specifically, for client file tree
The node that upper presence but server-side file tree are not present, shows that the node has been deleted, then creates " deletion " for the node
Operational order；For client file tree be not present but server-side file tree existing for node, show that the node newly increases
Node then creates " newly-built " operational order for the node, all exists for client file tree and server-side file tree but is somebody's turn to do
Node is different from the father node in server-side file tree in the father node of client file tree, shows that the node is moved
It crosses, then creates for " movement " operational order of the node, etc..File tree is compared with after the completion of operational order establishment, will be created
The operational order built is handed down to client, updates client data for it.
Briefly, it is exactly to preserve the operational order that a period of time generates recently in server-side, abandons operation not long ago
Instruction, this is suitable in the case of user often logs in, because user only downloads the behaviour in the short period after logging in every time
It instructs, then need not also preserve operational order not long ago in server-side.It is very one section long for sporadic user interval
According to the situation described in above-mentioned second point, the file tree of client, service are sent to server-side for the situation that time logs on
Node difference is extracted, creates corresponding operational order, client obtains these operational orders i.e. by documents tree node in end
It can complete " totally synchronous " of local data.In this way, service end spaces can be saved to the maximum extent, volume of transmitted data is reduced, is released
Place system resource.
In addition, in the case of client first logs into, as described in embodiment above, directly download server-side file and
The data such as bibliographic structure, not down operation instruct, operational order is downloaded when logging on and does synchrodata.
After client data synchronously completes, user can client file and catalogue carry out normal modification operation such as
Newly-built, deletion, movement, renaming etc..For newly-built file and catalogue, server-side preservation is uploaded to, under other clients
It carries and synchronizes.
During using operational order, client and server-side need to use identical operating protocol.In the implementation of the present invention
In example, there is unique identity code ID, the ID to be distributed by server-side for each file and catalogue, server-side and all clients
End performs unified operating protocol, and agreement specifically may include：NEW, new files or catalogue, operational order form are
{“command”：" new ", " type "：" dir ", " id "：" 12345 ", " paht "：“1/123/1234”}；REMOVE deletes text
Part or catalogue, operational order form are { " command "：" remove ", " type "：" dir ", " id "：" 12345 ", " path "：
“1/123/1234”}；MOVE, mobile file or catalogue, operational order form are { " command "：" move ", " type "：
" dir ", " id "：" 12345 ", " path "：" 1/123/1234 ", " dest "：" 1/123/234 " }, wherein path is to be moved
Catalogue, dest are the target directory being moved to；In addition, if client has recycle bin function, RECYCLE operations are can also be achieved
Instruction.For inquiry operation, since inquiry does not interfere with document directory structure, so without considering.
