Summary of the invention
Technical matters to be solved by this invention provide a kind of on remote server the method for preview OFFICE file, can be directly from the server preview OFFICE content, local client need not be installed OFFICE software, and is easy to use and reduce cost greatly.
The present invention be solve the problems of the technologies described above the technical scheme that adopts provide a kind of on remote server the method for preview OFFICE file; Comprise the steps: that the OFFICE file conversion that a) remote server is uploaded the user is the html file, and be preview file the html file storage; Control of authority when b) remote server is uploaded according to the OFFICE file is that preview file is provided with access rights; C) when client-requested visit OFFICE file, transfer it to visit to preview file.
Above-mentioned on remote server the method for preview OFFICE file, wherein, said step a) medium-long range server is the html file through calling the openoffice interface with the OFFICE file conversion.
Above-mentioned on remote server the method for preview OFFICE file, wherein, client is given in the url address that client is returned preview file in the said step c).
The present invention contrasts prior art has following beneficial effect: provided by the invention on remote server the method for preview OFFICE file; Remote server is the html file with the OFFICE file conversion; Thereby can be directly from the server preview OFFICE content; Local client need not be installed OFFICE software, and is easy to use and reduce cost greatly.
Description of drawings
Fig. 1 is the method flow synoptic diagram of the present invention's preview OFFICE file on remote server.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description.
Fig. 1 is the method flow synoptic diagram of the present invention's preview OFFICE file on remote server.
See also Fig. 1, specify the implementation process of the present invention's preview OFFICE file on remote server below:
Step S101: the OFFICE file conversion that remote server is uploaded the user is the html file, and is preview file with the html file storage, is the html file as call the openoffice interface through JODConverter with the OFFICE file conversion.
Step S102: the control of authority when remote server is uploaded according to the OFFICE file is that preview file is provided with access rights.
Step S103: when client-requested visit OFFICE file, transfer it to visit to preview file.
Specifically: 1. use a LINUX server and openoffice software is installed; 2. realize that the request that a SOCKET server reception user sends obtains fileinfo; 3. realize that the file that the JODConverter conversion is uploaded becomes HTML; 4. realize the request form of visit preview file and return the HTML content to front end.
After preview file generates, need carry out authority to preview file and judge.File as a.ppt produces is following:
a.ppt
a
|_a.html
|_a_img1.jPg
|_a_01.html
|_a_01_img.jpg
Wherein a is a file.In the net dish, the url address of source file is following:
http://***/attachment/openFile/MDffQwYWJlYWYIb1E2BmRRYwE8BjAGMQFsAT
kDOwU7UWIBNVFkWmxScZFFbUDQCYl1vCT0HOQMyAnkLcgtvAmIxNzE5NGUyMA％3D％3D.ppt
The user clicks preview, initiates the request of this file of preview to the back-end. and whether checking this user in rear end has this file, and with following form return data:
{″url″:string，″height″:int，″width″:int，“type”:}
After front end receives return data,
Then the url address format of preview file is following:
http://*****/attachment/openPreview/MDQwYWJdlYWYIb1E2BmRRYwE8BjAGMQ FsdddATkDOwU7UWIBNVFkWmxSZFFbUDQCYl1vCT0HOQMyAnkLcgtvAmIxNzE5NGUyMA％3D％ 3D/a.html。
This URL will be rewritten as following form by the web server:
http://***/attachment/openPreview.php?permission＝MDQwYWJdlYWYIb1E2BmRRYwE8BjAGMQFsdddATkDOwU7UWIBNVFkWmxSZFFbUDQCYl1vCT0HOQMyAnkLcgtvAmIxNzE5NGUyMA％3D％3D&file＝a.html。
Server will obtain file id according to the url address after the deciphering, and find the physical file address, thereby find the file after the file parameter.
Wherein, in order to reduce the request of database, when back-end encryption, the parent directory address of preview file is joined in the AES; Then when front end is asked to the back-end, directly from url, absolute path is obtained out, do not need requested database once more.
In sum; Provided by the invention on remote server the method for preview OFFICE file; Remote server is the html file with the OFFICE file conversion, thus can be directly from the server preview OFFICE content, no longer rely on relevant OFFICE plug-in unit in the browser; Local client need not be installed OFFICE software one by one, and is easy to use and reduce cost greatly.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little modification and perfect, so protection scope of the present invention is when being as the criterion with what claims defined.
