Description
Technical field:
The present invention relates to electricity field, relate in particular to the communication technology, concrete is online storage of a kind of pdf document and access method.
Background technology:
In the prior art, network becomes the important communication modes that exchanges and handle official business, and through the document of network delivery PDF, is file-sharing mode easily.But; If the owner of a document is not desirable to provide open download address; This part document just can not offer reading object with FTP or HTTP downloading mode, and can only send to all readings that need the document to the person with Email or communication tool by the document owner.Along with increasing of reader's quantity, the number of times of transmission is also more and more, also will particularly point out certain section content sometimes at certain one page, and the partial content of some chapters and sections perhaps only is provided, and need create new document copy partial content again and be used for externally open.
And for example the reader has obtained required document; Need go up in a plurality of different terminal (like PC, notebook computer, mobile phone etc.) again and preserve the document; This moment, the many places of wasting time and energy again copied same document, and when the reader had more various document, long-term collection and keeping had also brought trouble; Forget that through regular meeting a certain document can be somewhere, document disperses and takies a lot of memory spaces again.
Simultaneously; For the limited mobile device of hardware condition; The user experience that all can badly influence the reader to the support and the reading speed of document format; Though have the net dish that the storage mode of profile download is provided at present; But the size of a bigger pdf document, the transmission rate of network of living in etc. all can have influence on reader's reading method, and the reader only just need browse the content in certain one page wherein sometimes, but have to download entire document and use software to open browse work such as search.
Summary of the invention:
The object of the present invention is to provide online storage of a kind of pdf document and access method, online storage of described this pdf document and access method will solve the unfavorable technical problem of pdf document technology of sharing in the prior art.
Online storage of this pdf document of the present invention and access method; The process that comprises a pdf document in the process of file server storage pdf document and access file server; Wherein, Described file server is connected with network, in the process of file server storage pdf document, uploads pdf document through network to file server by the owner of pdf document described; File server is stored the pdf document of uploading; Set up file index, file index is set up successfully the back and is returned this pdf document unique identification number in memory space through network to the owner of this pdf document, and file server is judged the form of this pdf document; Original document is encrypted storage and carried out document according to the document page number and cut apart; The document fragment is through preserving after the processed compressed, and the document information after will handling is simultaneously preserved into database, in described access file server in the process of pdf document; The document reader utilizes the terminal to pass through network threaded file server; Utilize browser or ocr software file on the terminal to transmit the unique identifying number of this pdf document to file server, file server is obtained this pdf document according to the unique identifying number of this pdf document from memory space, and with all or part of content of this pdf document through browser or the ocr software file of network delivery to document reader's the terminal.
Further; Operating file hypervisor in described file server; Described file management package has been drawn together and has been uploaded interface and documentor, and the described interface of uploading receives the pdf document of uploading from network, and described documentor is encrypted original document storage and carried out document according to the document page number and cuts apart; And the document fragment compressed preservation, the document information after will handling is simultaneously preserved into database.
Further; The document reader utilizes browser or the ocr software file on the terminal to transmit the reading parameter of pdf document to file server, and file server is obtained the homologous segment of this pdf document according to the reading parameter of this pdf document and is delivered to browser or the ocr software file on document reader's the terminal from memory space.
Further, described reading parameter comprises the page number.
Further, the owner of pdf document uses http protocol to upload pdf document to file server.
Further; The document fragment that file server will be cut apart the back acquisition is saved in the distributed file storage system; Described distributed file storage system unified management and index file, and to carrying out the CDN distribution from the browser at document reader's terminal or the file access request of ocr software.
Further; During pdf document in the browser at document reader's terminal or the ocr software access file server; To file server queried access configuration, and the configuration information of this document that returns according to file server, the show tools that file server the is provided configuration that conducts interviews.
Further; During pdf document in the browser at document reader's terminal or the ocr software access file server; Transmit the request of preserving browsing label to file server, file server is preserved the document reader's log-on message or unique flag information with the solicited message of preserving browsing label.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention utilizes file server to cut apart, encrypt, store pdf document, and generates index simultaneously and corresponding to unique sign of this pdf document.The document owner can share pdf document through simply uploading; Unique mark number that using system returns just can be at multiple terminal, the chapters and sections browsed are wanted in multiple place through the Internet online browse; Need not bigger profile download is stored to this locality, need not to install the pdf document ocr software and just can pass through the network reading document.Reduced memory space requirement, reduced network traffics, accelerated the document loading velocity, brought very big convenience to the user to the terminal.
