Abstract
The present invention provides a kind of method of online preview network disk file, is related to Computer Applied Technology, and the present invention judges whether to support preview this document firstly, after user's select file.Then, it if not supporting preview, directly exits；If supporting preview, file is taken according to ID, and judge file type.Secondly, being translated into pdf document if it is Office type using OpenOffice, and pass the page back, being shown using PDF.js；If it is picture-type files, then passes the page back and show picture；If it is other type files, then page display text is passed back.It is able to use Dropbox preview Office file, picture and alternative document.
Description
Technical field
The present invention relates to Computer Applied Technology more particularly to a kind of methods of online preview network disk file.
Background technique
OpenOffice is a set of cross-platform office's software suite, can be in Windows, Linux, MacOS X (X11)
It is executed in the operating systems such as Solaris.It is compatible with each main office's software suite.
OpenOffice has the maximum potential quality for using open standard in Office suite.OpenOffice is an opening
Source code and completely free Office suite.In current commercial situations.If a manufacturer is in source code and the mark used
Retained in standard or maintained secrecy, then its potential non-technical reason is exactly to obtain commercial interest or the potential business of protection
Interests.OpenOffice completely free and open source code, then there will be no any non-in terms of using open standard
The burden of technology.OpenOffice default uses the OASIS ODF document format of standard open.OASIS document format independently of
Any manufacturer and realization, therefore ensure that her freedom and independence.And for its user, increase its selection
The freedom degree of Office product.
PDF.js is the PDF reader established by HTML5.Rely on open source community driving and the laboratory Mozilla
Technical support.Target establishes general a, platform for parsing and rendering pdf document based on web.
Summary of the invention
In view of problem above, the invention proposes a kind of methods of online preview network disk file must to solve existing Dropbox
The problem of capable of just checking file after must downloading.
The purpose of the present invention is what is be achieved through the following technical solutions,
A kind of method of online preview network disk file, firstly, judging whether to support preview this article after user's select file
Part；Then, it if not supporting preview, directly exits；If supporting preview, file is taken according to ID, and judge file type；Its
It is secondary, if it is Office type, it is translated into pdf document using OpenOffice, and pass the page back, it is aobvious using PDF.js
Show；If it is picture-type files, then passes the page back and show picture；If it is other type files, then page display text is passed back
This.
Include the following steps:
1, configuration OpenOffice service
2, user's select file
3, the page judges whether to support preview
4, server takes file according to file ID
5, server is to files in different types processing
Wherein,
Step 3 the following steps are included:
Step 3.1 obtains file type.From filename, suffix name, the type as file are intercepted.
Step 3.2 judges whether file type supports preview.If file supports preview, 4 are entered step；If file is not
It supports preview, enters step 33.
Step 3.3 prompt can not preview.In the page, the file of user's selection is prompted, does not support preview.
Step 4 the following steps are included:
Step 4.1 server is according to file ID, from data base querying the file information.
Step 4.2 takes file.The file of Dropbox deposits in Hadoop file system, obtains file according to path.
Step 5 the following steps are included:
Step 5.1 handles Office type file.
Step 5.1 further comprises following sub-step:
Step 5.1-1 judges whether file has been type PDF.It is to enter step 51-3, otherwise enters step 51-2.
Step 5.1-2 connection OpenOffice, switchs to pdf document for source file.OpenOfice service, can be by office text
Shelves are converted to the document of PDF format (including doc, docx, xls, xlsx etc.).
Step 5.1-3 passes pdf document back the page.Server sends data to browser, and pdf document is passed to the page.
Step 5.1-4 page invocation PDf.js shows pdf document.The plug-in unit is not necessarily to any local technical support, Ji Keshi
Present browser reads pdf document.
Step 5.2 further comprises following sub-step:
Step 5.2-1 passes picture back the page.Server sends data to browser, and picture file is passed to the page.
The step 5.2-2 page shows picture.It uses<img>label directly displays picture.
Step 5.3 further comprises following sub-step:
Step 5.3-1 passes text back the page.Server sends data to browser, and text is passed to the page.
Step 5.3-2 page display text.<div>label is used, plain text will show that text, html file are then browsed
Device resolves to webpage.
The invention has the following advantages that
1, browser, can preview office file without installing any plug-in unit.
2, can preview file type it is more.Support office file, picture, text-only file etc..
3, the pdf document of office file conversion, is deleted after use, is mitigated file system and is stored pressure.
Detailed description of the invention
Fig. 1 is general flow chart of the present invention using the method preview network disk file of online preview network disk file.
Specific embodiment
