Description
Technical field
The present invention relates to the network data processing field, particularly relate to a kind of method and system of compression coding information resource address, and corresponding decompression method.
Background technology
Available every kind of resource on the network: html document, image, video segment, program or the like can be positioned by a unified resource identifier (Uniform Resource Identifier is called for short " URI ").URI generally is made up of three parts: the naming mechanism of access resources; Deposit the host name of resource; The title of resource self, path or parameter.
For example, http://www.webmonkey.com.cn/htm/htm140/; This URI has represented that can be passed through a http protocol accessed resources, is positioned on the main frame www.webmonkey.com.cn, gets final product by path "/html/html40 " visit.
What relatively use always in the wire transmission field of network resource data is URL (Uniform ResourceLocation, URL(uniform resource locator)), and URL is a subclass of URI naming mechanism.Generally speaking, URL can think to be used on the Internet character string of descriptor resource, mainly is used on various WWW CLIENT PROGRAM and the server program.
But along with getting more and more of information resources in the network, the above-mentioned data length of URI that is used for addressing or sign internet information resource is also increasing, the length of more existing URI has reached hundreds of even has gone up kilobytes, so how the URI of big data quantity issues and propagates, the existence that makes more user can learn the resource that it identifies is a very thing of difficulty.
Prior art has proposed a solution: the URI coding is formed two-dimensional bar, and then issue and propagate, the coding form of two-dimension code can be used the area of plane efficiently, under equal area, can hold more information than literal, and two-dimension code also is convenient to the user and is imported URI very much.Along with popularizing gradually of mobile terminal device camera function, make the advantage of this scheme more and more protrude.This scheme makes URI to propagate by planographic, for example two-dimensional bar is printed on the printed matters such as newpapers and periodicals, magazine, placard, thereby mobile terminal device obtains this URI by taking, decoding, and then obtains corresponding information resources by the address sensing of this URI.
The proposition of this scheme can help really URI multi-faceted, convenient, issue accurately and transmit.But, because the URI length variations of various information resources is very big, the length of some URI reaches hundreds of even goes up kilobytes, and the data length of some URI only has only several or tens bytes, this just requires: the data processing compatibility of encoding device, decoding device and transmission equipment is very strong, can either satisfy the needs of short URI encoding and decoding of data length, also want to satisfy the needs of long URI encoding and decoding of data length, thereby the performance of the said equipment is proposed comparatively harsh requirement; Secondly, because the data length of URI still has the trend of increase, for the URI of these big data quantities, even adopting two-dimensional bar code propagates, the two-dimensional bar code data volume that its coding obtains is still very big (from the plane, be exactly that two-dimensional bar code sign indicating number shape increases, printing area increases), low side two-dimensional bar code recognizing apparatus for similar mobile phone, cause the reduction of discrimination and the difficulty on the recognition speed, for example, can't take the processing procedures such as decoding that calculated performances such as the two-dimensional bar code of big sign indicating number shape or internal memory can't satisfy this two-dimensional bar code; And, printing or display unit are also proposed higher requirement, on the layout of printing and display medium, also caused certain difficulty.

Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Core concept of the present invention is, by of the management of compression service device, URI is unified the approximate short URI of boil down to length, and generate coding according to the short URI after the compression to each user's space, the demonstration and the recognition difficulty of described coding are reduced, promote issue and the propagation of URI.
With reference to Fig. 1, be the flow chart of steps of the described a kind of compression coding information resource address of the embodiment of the invention.
User of the present invention needs the service of elder generation to server application information resource address compressed encoding, by modes such as registrations, becomes the use user of described service, below with the use user who refers to obtain described service per family.Server is opened up certain user's space at the registered user, and can manage this space by user ID.
Original URI described in the present invention can be used to provide browsing of various information resources, for example, and music, picture, enterprise product, picture or recreation or the like.
After step 104, server receive original URI, determine resource sequence number ID.The index number of information resources under user ID that described resource sequence number ID is original URI correspondence, it promptly can be the flowing water sequence number that server generates automatically, also can be the title of user oneself definition, only need to keep uniqueness to get final product down in user name space (user ID).Hence one can see that, can have a plurality of different information resource address under the same user ID, and same information resource address also may exist and has identical or different resource sequence number ID under the different user ID.Server is preserved the corresponding relation of resource sequence number ID and original URI.
The method that shortens URI has multiple, and be divided into substantially: a kind of is the title that server centered is distributed compression URI, is responsible for the uniqueness of title by server, and shortcoming is that the title that server centered is distributed does not have concrete meaning usually, is difficult to memory; Another kind is the title of User Defined compression URI, by the server authentication uniqueness, user oneself selects the title of uniqueness, though described mode user can choose the title of being convenient to remember, but the title resource of being convenient to remember is limited, will soon use up, when the compression URI quantity of user registration is big, the probability of the name conflict of being convenient to remember will increase greatly, causes the user often can't obtain the resource name of oneself wishing.
At above-mentioned traditional approach, the preference rule that the present invention adopts can be compressed into the URI of random length the compression URI that is similar to regular length, on the one hand, has eliminated the problem that the resource name repeats significantly; On the other hand, be convenient to the resource content of user management oneself, meet most of people's data management custom.
Above-mentioned steps has been finished the process that original URI is converted to compression URI, has obtained the relatively more fixing compression URI of data length, has reduced the obstacle of URI in issue and transmission course.Preferably, if adopt the mode of coding to carry out the propagation of URI, then can reduce performance requirement to coding/decoding apparatus.For example, URI combines with the application of two-dimensional bar code with compression, then can also may further comprise the steps:
If described coding form adopts optical signalling, then preferably adopt the image information of one dimension sign indicating number, two-dimension code or process data-modulated, because existing mobile terminal device much has camera head.For example, the compression URI two-dimension code that enterprise will generate is printed on the printed matters such as newpapers and periodicals, magazine, but the reader utilizes the camera cell phone of carrying to open decoding software and scans described two-dimension code, the decoding back just can obtain to compress URI, thereby by the link resources that the inverse process of above-mentioned steps is visited original URI, specifically content describes in detail again below the step of decoding visit.
Because two-dimensional bar code or other electronic code sign indicating number shapes of above-mentioned generation are less, therefore can dwindle printing area greatly, reduction is to the demonstration and the recognition requirement of recognizing apparatus, be convenient to that low side recognizing apparatus such as portable terminal is high-speed, the recognition work of finishing of high success rate, the display unit that is fit to low resolution shows.
The present invention is preferred, and compression service device or decompression can also provide the access control to each URI under the user name space, and the user can optionally carry out the authority setting to URI, can also different rights be set to different URI.And during the URI that needs to preserve under certain user ID of visit, just need pass through Authority Verification.
The compression URI that obtains embodiment illustrated in fig. 1 can have the dual mode performance:
One, adopt the mode of similar URL, (for example, http://kkm.cc/tom/love, wherein http://kkm.cc/ is that decompression server ID, tom are user ID, love is resource sequence number ID), the user can visit this URL link by wired or wireless mode can obtain the service of decompressing, in fact might not be address information among the URI as the tom of user ID with as the love of resource sequence number ID, also can be used as parameter, extract by the decompression server and get final product.
They are two years old, the mode that adopts similar short message (for example, the packet of prescribed form), for example, decoding device can be directly with user ID and resource sequence number ID among the compression URI after obtaining compression URI, adopt the mode of short message, send to decompression server (learning), thereby obtain the service of decompressing by the decompression server ID among the compression URI.Certainly, those skilled in the art can be according to triggering decompression service manner difference, and adopt different information packaged types, the present invention to only require that compression URI comprises that decompression server ID, user ID and resource sequence number ID get final product to compression URI.
Need to prove that above-mentioned steps is to describe as a kind of embodiment, therefore under suitable situation, the front and back order of some step can be adjusted according to practical situations, but does not influence the explanation of the method for the invention.
After the original URI of directional information resource is compressed to compression URI, can solve the propagation problem of URI, if visit described information resources then also need to compress the conversion of URI to original URI.
With reference to Fig. 2, be the decompression step flow chart of the corresponding flow process shown in Figure 1 of the present invention.User described in Fig. 2 refers to visit the user of compression URI, and this user can have user's space in the compression service device, also can not have user's space, gets final product because this user only needs to visit the decompression server.Certainly, if the compression URI that need visit at this user has the authority setting, then this user must be by the purview certification of decompression server.
Step 202 triggers the service of decompression according to described compression URI.
For example, if adopt the http agreement to trigger, then compress the form that URI can adopt URL, the user can trigger the service of decompression by import this compression URI in browser's address bar; If adopt the mode of short message to trigger, then decoding device can be directly with user ID and resource sequence number ID after obtaining compression URI, adopt the mode of short message, send to decompression server (learning), thereby obtain the service of decompressing by the decompression server ID among the compression URI.
Above-mentioned access rights can adopt following several set-up mode: only at certain specific URI access rights are set; Perhaps, former registration user is provided with access rights at all own set compression URI, visitor's identity is authenticated white list for example, blacklist etc.; Also above-mentioned two kinds of authority setting modes can be used in combination, both authenticate visitor's identity, require to provide the access code of compression URI again.
In sum, the process of information resources URI compressed encoding and user need apply in a flexible way according to different practical applications according to the process of the original URI link resources of compression URI coding visit.
According to the description of above-mentioned Fig. 1 and Fig. 2, describe for example below:
For example, need the original address of compressed encoding to be:
http://www.bfgq.com/play_01/play01_0004.rm
The decompression server address that provides is http://kkm.cc
The registered user is: tom
This user is this Internet resources called after: love
This user is provided with password for this short address: 1234
If adopt the mode of http agreement to trigger the decompression server, then the short address after the conversion can be http://kkm.cc/tom/love.Calling party just can be visited this short address (for example, getting final product in the address field input) by the browser of local computing device, is equivalent to send customer parameter tom and resource parameters love to decompression server kkm.cc; The decompression server needs calling party to enter password with tom and these two parameter query concordance lists of love, discovery, the requirement that the server that then decompresses is entered password to the calling party proposition, and calling party enters password 1234; This password of decompression server authentication is correct, then extracts original URL from concordance list, returns to calling party; The original URL of user capture obtains corresponding mp3 music file.
If adopt the mode of short message to trigger the service of decompression, then need to preset in advance the packet of specific format, comprise the short message server 10010 that can note connects in the packet of compression URI, customer parameter tom and resource parameters love.The user can manually send customer parameter tom and resource parameters love to short message server 10010, and for example form is: tom.love; Certainly, user's mobile terminal device also can be resolved the packet of described compression URI automatically, obtains following information according to initialize format: short message server 10010, customer parameter tom and resource parameters love; Automatically two parametric t om and love are sent to short message server 10010 then.Short message server 10010 is resolved after receiving this message, obtains two parametric t om and love; These two parameter query concordance lists of short message server 10010 usefulness tom and love extract original URL from concordance list, send to calling party by note; The user receives note, visits original URL, obtains corresponding mp3 music file.Certainly, if feasible, short message server 10010 also can directly link original URL and obtain and directly return required information resources to the user.
Certainly, also can adopt other triggering mode, only need set regular the getting final product of packet of specific format to the communication protocol that this triggering mode is used, the present invention does not describe in detail one by one at this.
Based on foregoing invention thought, the present invention also provides a kind of system of compression coding information resource address, is used to realize that the URI after the compressed encoding of the original URI of information resources and user are according to compressed encoding visits the resource that original URI links.With reference to Fig. 3, be the structured flowchart of a kind of compression coding information resource address of the present invention system.Described system comprises: interface unit 301, memory cell 302, compression unit 303, decompression unit 304, and coding unit 305, decoding unit 306, control of authority unit 307.
After interface unit 301 received the original URI of information resources and determines the resource sequence number ID of described URI, described memory cell 302 was preserved the corresponding relation of resource sequence number ID and original URI under the user ID of correspondence.
A kind of is the mode that adopts similar URL, (for example, http://kkm.cc/tom/love, wherein http://kkm.cc/ is that decompression server ID, tom are user ID, love is resource sequence number ID), the user can visit this URL link by wired or wireless mode can obtain the service of decompressing, and might not be address information among the URI as the tom of user ID with as the love of resource sequence number ID in fact, also can be used as parameter, get final product by the extraction of decompression server;
Another kind be adopt similar short message mode (for example, the packet of prescribed form), for example, decoding device can be directly with user ID and resource sequence number ID among the compression URI after obtaining compression URI, adopt the mode of short message, send to decompression server (learning), thereby obtain the service of decompressing by the decompression server ID among the compression URI.Certainly, those skilled in the art can be according to triggering decompression service manner difference, and adopt different information packaged types, the present invention to only require that compression URI comprises that decompression server ID, user ID and resource sequence number ID get final product to compression URI.
Above-mentioned by compression unit 303, original URI can be converted to compression URI, obtain the relatively more fixing compression URI of data length, reduced the obstacle of URI in issue and transmission course.And described reduced rule is a preferred version of the present invention, compares with the conventional compression method, can eliminate the problem that the resource name repeats significantly, and is convenient to the resource content of user management oneself, meets most of people's data management custom.
The invention provides two kinds and trigger the decompression service manner, ditto described: as to adopt the http agreement to trigger and the triggering of employing short message.For the triggering mode of http agreement, decompression unit 304 therefrom obtains described user ID and resource sequence number ID according to URI reduced rule analysis compression URI content; And for the short message triggering mode, decompression unit 304 can directly receive user ID and the resource sequence number ID among the compression URI.
Preferably, electronic codes such as the conversion between the above-mentioned length address and two-dimension code are used combine, also need to be provided with coding unit 305 and decoding unit 306.Described coding unit 305 is used for the compression URI of compression unit 303 is encoded, and decoding unit 306 is used to gather the coding of compression URI, decodes and obtains compression URI, and send to interface unit 301 with the form of http agreement.Usually, described decoding unit 306 is arranged at the mobile terminal device that decoding software is installed, the user utilizes described mobile terminal device collection to comprise the two-dimension code of various information, sends to interface unit 301 after the decoding, by the decompression unit 304 final resources that obtain original URI link.If described mobile terminal device adopts short message way to send, then described decoding unit 306 can also be resolved the compression URI packet of specific format, and the user ID and the resource sequence number ID that directly will compress among the URI send to interface unit 301.But the present invention does not limit decoding unit 306 must be arranged on user side, also can be arranged on server end and realize.
Because two-dimensional bar code or other electronic code sign indicating number shapes of above-mentioned generation are less, therefore can dwindle printing area greatly, reduced the requirement of various recognizing apparatus, but also reduced the requirement of printing or display unit, especially for the low side recognizing apparatus of similar mobile device, be more convenient for distinguishing and showing.
The present invention is preferred, also is provided with control of authority unit 307, and the two-stage rights management mechanism is provided, and is used for user ID and every kind of information resources are provided with authority and conduct interviews checking.Before compression unit 303 is carried out, can take multiple access control policy, as cryptoguard or white list, blacklist etc., the user ID that sends the original URI of information resources is verified; And analyze the second portion user ID and third part resource sequence number ID of compression URI at decompression unit 304 after, also need the Authority Verification that conducts interviews.For the checking of user ID, server is searched access control list according to user ID, determines whether the user has the right to conduct interviews; For the access control of every kind of information resources, need user's input reference password, after passing through, checking just can visit.
The present invention is preferred, also is provided with control of authority unit 307, and the two-stage rights management mechanism is provided, and is used for user ID under the user's space and information resource address are carried out control of authority.Registered user for the application compression service, control of authority unit 307 is by searching the user ID access control list, perhaps adopt other access control policies, for example white list (having only visitor on the white list just to allow visit), blacklist (visitor on the blacklist does not allow visit) etc. are determined user's login system of whether having the right.And, also allow the original URI under the own space of user selection that different access rights are set.
And for the user who visits original URI according to compression URI, because specific or all original URI are provided with access rights under the user's space, so at first need to obtain access code or user ID to having the user who compresses URI, access control list is searched according to user ID again in control of authority unit 307, and the visitor is carried out authentication.As previously mentioned, control of authority can be adopted multiple mode, as cryptoguard or white list, blacklist etc.Then, when the original URI that visit is encrypted, also need calling party that password is provided, just can obtain original URI.
System provided by the invention is fit to the recognition of low resolution device and shows two-dimensional bar code under the prerequisite that guarantees discrimination and recognition speed; And the present invention realizes simply, as long as with the regular electronic code that generates of mobile device scanning the present invention, just can be directly connected on the website and download, no longer needs loaded down with trivial details operating process.
