Abstract
The invention relates to the technical field of WEB development, in particular to a file on-line previewing method. A text file is converted into a PDF file through the third-party tool wps, and the PDF file is displayed through a front-end PDF plug-in so that the on-line previewing can be achieved. The file on-line previewing method is more rapid, safer, more accurate, higher in speed and smaller in number of lost data. The file on-line previewing method can be widely applied to the file converting and file previewing operation functions.
Description
Technical field
The present invention relates to EB development technique field, be specifically related to the online method for previewing of a kind of file.
Background technology
At present, in internet, a lot of platforms are all supported text, and as the online preview effect of txt, office file, this technology is all changed realization by file at present: the first step, first transfers the various files of txt or office to the file of pdf form; Second step, transfers pdf file to the file of swf form; The 3rd step, by third party swf plug-in unit, shows the file of swf form, reaches the effect of online preview.
Because in traditional method, need to increase and transfer pdf file the flow process of swf file to, therefore can be slow in speed, and in transfer process along with the increase of conversion times, the phenomenon of data distortion also can increase thereupon.Therefore poor on whole structure.
Summary of the invention
The technical matters that the present invention solves is to provide a kind of file online method for previewing; Need only can realize by a file conversion the online preview of file.
The technical scheme that the present invention solves the problems of the technologies described above is:
By third party's instrument wps, transfer text to pdf document, then show by front end PDF plug-in unit, thereby realize online preview.
Comprise the following steps:
The 1st step, installation wps Open-Source Tools;
The 2nd step, server, by wps Open-Source Tools, read the particular content of text;
The 3rd step, by calling the method that saves as of wps, directly file is saved as to pdf document;
The 4th step, the front end JSP page, by PDFObject plug-in unit, read pdf document flow by the mode of stream from specified path, and be presented in PDFObject framework.
The text formatting of supporting comprises DOC, DOCX, PPT, PPTX, XLS, XLSX, TXT, PPD.
The invention has the beneficial effects as follows: the inventive method speed is faster, because only needing a file conversion can reach preview effect; Secondly, to the pressure of server still less, server is without the file that pdf file is transferred to swf form for this method; The 3rd, still less, because lacked once conversion, data validity is higher for the probability that data distortion appears in this method; Wps file is to save as method by directly calling it, and original file is saved as to pdf document, and therefore at server resource, taking can be still less.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described:
Accompanying drawing is the inventive method process flow diagram.
Embodiment
As shown in drawings, the present invention, by third party's instrument wps, transfers text to pdf document, then shows by front end PDF plug-in unit, thereby realizes online preview.Concrete steps are as follows:
The 1st step, installation wps Open-Source Tools;
The 2nd step, server, by wps Open-Source Tools, read the particular content of text;
The 3rd step, by calling the method that saves as of wps, directly file is saved as to pdf document;
The 4th step, the front end JSP page, by PDFObject plug-in unit, read pdf document flow by the mode of stream from specified path, and be presented in PDFObject framework.
Preceding method supports that text formatting comprises under DOC, DOC, T, PPD under PPT, PPT, under lower LS, lower LS, under T.
