Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The present invention proposes a kind of new-type compression method, local file automatic pressing can be contractd upload on the webserver and store, the corresponding cloud packed data of server generates cloud compression link and sends to client again, and client user can issue cloud compression link other client user.User, by clicking described cloud compression link, just can directly download corresponding cloud packed data from network and carry out decompress(ion).
Below all data flow to be uploaded onto the server by this employing and the new type of compression mode generating cloud compression link calls that cloud compresses, to compress and cloud packed data after uploading onto the server is called cloud compressed file.
Below by embodiment, this new type of compression mode is described in detail.
With reference to Fig. 1, it is a kind of compression method flow chart based on cloud compression link described in the embodiment of the present invention.
Step 11, triggers cloud compression request;
Generally trigger cloud compression request by user operation, user selects in client the local file data will carrying out cloud compression, is then triggered by certain operation and carries out cloud compression to this file data.
Wherein, described " certain operation " can be click right menu, selects " adding cloud compressed file to " option to trigger; Also can be open the cloud compressed software main window that client installs, select File be also clicked " cloud link " option and is triggered; Or, also can be other operation triggering mode, specific implementation can be carried out according to practical application.
User is after client triggers cloud compression request, and client and server carries out the process of step 121 and step 122 respectively:
Step 121, client carries out automatic Compression according to described cloud compression request to the local file data that will compress, and the data upload after compression is stored to server as cloud packed data;
Namely client is by compression with upload to combine and automatically complete;
Wherein, the described local file data that will compress can be Single document, also can be multiple file, can also be Single document folder or multiple file.Namely can be a cloud compressed file by Single document or multiple file, Single document folder or multiple file automatic Compression, and store on the server.The compressed package of multiple file or folder may be comprised in this cloud compressed file.Above-mentioned cloud packed data can refer to described cloud compressed file.
Further, the local file data that compress can be the file or folders before compression, can also be the files carrying out overcompression in this locality.
Step 122, server generates corresponding cloud compression link according to described cloud compression request, and this cloud compression link is sent to client;
Server can generate unique cloud compression link by corresponding each cloud compressed file, and the client of request is issued in this link.
In the present embodiment, described cloud compression link is a hyperlink, and this hyperlink can comprise host-host protocol and file identification information, and described file identification information can be unique cloud compressed file sequence number.In addition can also comprise the information such as filename, file size, network server address (finding corresponding server for client) in described cloud compression link, these information by client upload to server.Wherein unique cloud compressed file sequence number can adopt Hash (Hash) algorithm or MD5 scheduling algorithm to generate, if hash algorithm then can directly represent with hash value.Such as, one comprise host-host protocol, unique cloud compressed file sequence number, filename, file size cloud compression link be expressed as follows:
cloudzip://57C4862BB8058ADED8CA1AB8667A2C59BB5EE0B3&name＝Avatar+1080p&length＝7062222453
Wherein, the constituent instruments information of described unique cloud compressed file sequence number corresponding server medium cloud packed data, namely correspond to the constituent instruments information of the cloud compressed file on server in database.Described constituent instruments information comprises the sequence number (being sequence number usually with hash value) of file, the information such as title, the bibliographic structure of file, the size of file of file.
According to the difference of practical application, above-mentioned steps 121 and 122 can be carried out simultaneously, and also can successively carry out, this is described in detail in the content below.
After server generates cloud compression link, server also continues to perform step 13.
Step 13, server is set up and the mapping relations of cloud compression link cloud packed data.
Namely the corresponding relation of cloud compressed file and cloud compression link is set up on the server.
Through the process of above-mentioned steps, a file data can be collapsed into a hyperlink, and this hyperlink can be sent to almost Anywhere.Client user clicks this hyperlink, just can directly download corresponding cloud compressed file from network and carry out decompress(ion), thus utilize the Internet to achieve sharing files.Therefore, method described in the embodiment of the present invention is used, the file of arbitrary size, no matter be 10M, 100M or 500M, 1G, as long as server space is enough large, bandwidth is enough high, all can be compressed into a hyperlink, be convenient to very much send to other people, save transmission bandwidth, be easy to share, almost any can the place of input character, no matter be on MSN, or in microblogging, forum, mail, can file be shared and not account for annex space, without the need to uploading.
In addition, by method described in above-described embodiment compared with the mode of net dish upload file, also there is following difference and advantage:
The first, the mode of net dish upload file, as a rule in order to save the transmission time, needing user first manually to use traditional compressed software to compress local file, generating a compressed package, and then manually use net dish to upload compressed package.And the embodiment of the present invention is by compression with upload to combine and settle at one go, user just can obtain a hyperlink after clicking cloud compression, without the need to manual compression file and then manually upload and wait operation, saves and operates and compress uplink time, very convenient.
The second, the mode of net dish upload file needs user to register, user need through open any browser, input network address, log in, the complicated net dish operating procedure such as to upload.And method described in the embodiment of the present invention installs cloud compressed software in client, directly trigger cloud compression by direct click right menu or the mode such as cloud compressed software of opening client, therefore the present invention operates directly convenient.
Based on content embodiment illustrated in fig. 1, the present invention also can realize more function, and has more advantage, illustrates respectively below.
1, step 121 and 122 can perform simultaneously, also can successively perform;
If described request is first compression and uploading data, regeneration cloud compression link, then described server pass on the client complete after, then generate corresponding cloud compression link according to described request; Namely step 121 first performs, and after treating that step 121 is finished, step 122 starts to perform again;
If described request is first generate cloud compression link, then described server generates corresponding cloud compression link according to described request after receiving described request, and this cloud compression link is sent to client immediately, receives the cloud packed data of client upload simultaneously; Namely step 121 and 122 can perform simultaneously, also can first perform step 122 and perform step 121 again.
For above-mentioned the second situation, time on the data flow in cloud compression process not being uploaded onto the server, can first generate cloud compression link, and then continue uploading data stream, otherwise for some comparatively large files, wait for possibly and just can obtain cloud compression link in tens minutes.Such as the cloud compressed software of client is minimized to pallet slowly to transmit on backstage, user need not wait for just first can send out mail to other people cloud compression link, and when other people see this mail, data flow is end of transmission, can normal decompress(ion).
Such as, if the compressing file of 100M is to 50M size when generating cloud compression link, the data of 50M size need transmission about 8 minutes under 1Madsl broadband.When transmitting data (or transmitting data) after formerly generating cloud compression link simultaneously, only need just can generate cloud compression link in tens seconds, then user A can issue others cloud compression link mail immediately, simultaneously cloud is compressed in backstage and transmitted data with 8 minutes again, and when user B checks mail after several hours data end of transmission can decompress(ion).The user A of such cloud compression has saved 8 minutes.
2, limit decompress(ion) is uploaded in limit compression;
If described request is first generate cloud compression link, then can also comprise:
Client do not upload complete in, another client downloads by clicking cloud compression link the part cloud packed data uploaded from described server.
Formerly generate cloud compression link, and then continue in the mode of uploading data stream, can when not uploading complete, the people of decompress(ion) cloud compression link can download the data flow uploading part and carry out decompression operations.Can allow the people of the people and decompress(ion) cloud compression link that make cloud compression link within the shortest time, realize compression and decompress(ion) like this.
Such as, when limit upload cloud compressed data stream limit downloading data stream carry out decompress(ion), user A is after spending the file of 100M cloud compression in tens seconds, immediately cloud compression link Email attachment is issued user B, now cloud compression limit uploading data stream, user B can carry out download decompress(ion) to the partial data stream uploaded immediately, and both sides do not need to wait for.
3, server avoids the problem of repeated storage;
When use the people of cloud compression many especially after, the storage file on server has a lot of repetition.In order to avoid this problem, can carry out hash value calculating on the server to file, if hash value is identical, so two files are identical, then only can preserve a file on the server.On local client, hash value calculating being carried out to file, by showing to contrast with the Hash on server, if there is identical value, namely server having had identical file, then do not carry out transmitting this file, and then save server space and bandwidth.
And server, when generating cloud compression link, if there is user to carry out the cloud compression of same file, then there is identical file in server, so can save this file of transmission, can complete cloud compression instantaneously, only need 1 second." person of the bearing cat .rmvb " of a such as compressed 100M of user A cloud, then server is present in " person of bearing cat .rmvb " file, then during user B cloud compression " person of bearing cat .rmvb ", owing to eliminating the transmitting procedure of this file, only need within 1 second, cloud compression link can be obtained.
Foregoing can be realized by following steps:
After described triggering cloud compression request, also comprise:
1) the constituent instruments information (comprising hash value) of local file that client will be compressed is uploaded to server;
2) whether server stores identical file according to described constituent instruments information inquiry, and Query Result is returned to client, comprises the constituent instruments information of the partial document that server does not store in described Query Result;
Namely whether store same file by the comparison query of hash value, Query Result generally comprises three kinds:
The first All Files being client will be compressed all stores on the server;
The All Files that during the second, client will be compressed all does not store on the server;
The third is in the client All Files that will compress, and has partial document to store on the server, also has the file of remainder not store on the server.
3) client is according to described Query Result, and the local file data do not stored by server carry out automatic Compression, and storage that the cloud packed data after compression is uploaded onto the server;
4) if server has stored the All Files that client will be compressed, then the cloud compression link of correspondence is directly sent to client by server.
4, breakpoint transmission;
Compression upload procedure can support breakpoint transmission, after namely disconnecting network, can proceed cloud compression when again connecting from breakpoint.
Due to file very large time have network disconnect situation, can cause cloud compress interrupt, cause the partial data stream of transmission transmit in vain and need again to transmit.For this problem, piecemeal process can be carried out to the data of large files, such as, carry out the calculating of piecemeal hash value, if server exists identical data block hash value, then this part need not be transmitted again, thus realize breakpoint transmission, namely realize the continuous pressure of breakpoint with breakpoint transmission.In addition, also directly can do data markers at breakpoint place, realize the cloud compression of breakpoint transmission.
Foregoing can be realized by following steps:
Cloud packed data piecemeal after compression to upload onto the server storage by client;
If upload failure after client upload partial data, then described method also comprises:
Client restarts uploading data, if server exists identical data block, then client no longer uploads described identical data block;
Or the breakpoint place that client is uploading failure makes marks, then continue uploading data from the breakpoint of described mark.
5, password is added;
Cloud compression can Choice encryption, and to realize the encryption to cloud compression link, the people carrying out decompress(ion) cloud compression link needs input password just can open, and improves privacy.Select interpolation password both can encrypt when this locality is compressed then to upload, also can encrypt again after server receives the data uploaded.
Foregoing can be realized by following steps:
After described triggering cloud compression request, also comprise:
Client adds password before compression;
Or, during server stores cloud packed data, add password.
6, annotation is added;
Can select to add annotation when carrying out cloud compression, to realize the annotation to cloud compression link, annotation can comprise: the information such as author, related description making cloud compression link, facilitates download person to check.Namely these annotation information can be stored in cloud compressed file when client compressed file, also can be sent on server by client and also store on the server.
Foregoing can be realized by following steps:
After described triggering cloud compression request, also comprise:
Client adds annotation information before compression;
Or, during server stores cloud packed data, add annotation information.
7, compress with different compression levels;
When carrying out compressing file, different compression levels can be selected to compress.Further, can also intelligent decision compression ratio and automatically compressing with different compression levels, such as to store, the compression level such as the fastest, standard.Such as the file that some compression ratios are very low, as files such as rmvb, mp4, mp3, directly with store compressed mode uploading data stream, CPU can not expended.
Foregoing can be realized by following steps:
After described triggering cloud compression request, also comprise:
Custom end intelligent judges compression ratio and adjustment compression level compresses automatically.
8, cloud compression confirms.
Because user may misoperation, such as " adding cloud compression to " file command is performed by mistake, thus secret files passe causing privacy leakage to server by mistake, cloud compresses this file, to improve the accuracy of operation therefore user can be allowed to be confirmed whether before the compression of execution cloud.
For above-mentioned cloud compression method, the embodiment of the present invention additionally provides corresponding decompression method, as shown in Figure 2.
With reference to Fig. 2, it is a kind of decompression method flow chart based on cloud compression link described in the embodiment of the present invention.
Step 201, triggers the request of cloud decompress(ion) by opening cloud compression link;
