Message-driven multi-type file preview system

Abstract

The invention discloses a message-driven multi-type file preview system. The message-driven multi-type file preview system comprises a trigger assembly, a message queue, a Linux cluster, a Windows cluster and a preview presentation assembly, wherein the trigger assembly is used for converting request information into a preview request message when being triggered by preview request information of a source file of a user and transmitting the preview request message to the message queue; the message queue is used for saving the received preview request information persistently; the Linux cluster is used for monitoring a preview request message of the message queue, and converting a source file of the preview request message into a preview file; the Windows cluster is used for converting an Office document into a PDF type preview file when being triggered by a preview request message of the Linux cluster; and the preview presentation assembly is used for receiving a corresponding preview file for presentation when being triggered by the Linux cluster. The message-driven multi-type file preview system can be applied to various terminals such as computers, mobile phones and tablet computers, and installation of various types of huge professional software is avoided, so that files of various formats can be previewed through the system, and great convenience is brought to the user.

Description

technical field [0001] The invention relates to the technical field of file processing, in particular to a message-driven multi-type file preview system. Background technique [0002] With the continuous development of computer technology and Internet technology, there are more and more types of files on the Internet, and the demand for data sharing is also increasing.

Problems solved by technology

[0002] With the continuous development of computer technology and Internet technology, there are more and more types of files on the Internet, and the demand for data sharing is also increasing. In the past, when users obtained files from the Internet, they had to judge the file type by themselves, and then install a professional browser Software can open various types of files, and various professional software is not suitable for obtaining, bulky and expensive, which brings great troubles to users

[0003] In the patent No. 200610113599.5 filed by NetEase Youdao Information Technology (Beijing) Co., Ltd. on October 8, 2006, it proposed "a device for quickly previewing search results based on a search engine", but this preview system can only preview The content of the webpage cannot meet the preview requirements of various types of files in the rapidly developing Internet environment; Guoyun Technology Co., Ltd. proposed "a file online Preview method", and Shenzhen Yuanxing Technology Co., Ltd. proposed "a Hadoop-based distributed file preview method and system" in the patent No. 201210233929.X applied for on July 06, 2012. For the preview of Office document files, WPS or OpenOffice is generally used to convert Office documents to PDF documents, which will bring a series of problems such as poor Microsoft Office document preview experience and display errors in format formulas, and this is only for document file previews. , and cannot adapt to the preview requirements of various types of files that appear in the rapidly developing Internet environment, and for using Microsoft Office, which has the highest market share, to realize preview conversion, the existing technology cannot meet such requirements. Even if the requirements are met, the spent costly

[0004] In addition, the patent No. 201410199197.6 filed by Shenzhen Zhongbo Kechuang Information Technology Co., Ltd. on May 12, 2014 proposed "a method for previewing files and a file processing system". Its file preview based on FLASH is to The file is converted to the SWF file format, because the conversion speed of the SWF file is relatively slow, which greatly affects the efficiency of the preview system

[0005] In particular, existing preview systems mostly use APIs from third-party vendors such as OpenOffice or WPS to preview Office documents, but this way of previewing cannot accurately display advanced content such as complex charts and mathematical formulas, and for CAD files, POSTSCRIPT files There is no preview platform for professional files such as EPS and EPS files. Users must first install huge professional software to open and view them, which is not very convenient to use.

[0006] In short, in the prior art, to preview various files, it is necessary to install the corresponding professional document browser before previewing the content of the document, which is extremely inconvenient for users, and will also cost users a lot of unnecessary time and energy.
