Method for realizing instant previewing of file

Abstract

The invention discloses a method for realizing instant previewing of a file, which comprises the following steps: implanting an asynchronous transcoding program into a computer, uploading the file to the computer by a user, and calling the asynchronous transcoding program from a background server of the computer; the method also includes that the asynchronous transcoding program obtains information of an uploaded file and creates an auxiliary thread to analyze the file to obtain a conversion result; the auxiliary thread sends the obtained conversion result to the computer through the asynchronous transcoding program, the computer obtains the conversion result, and the conversion result comprises a webpage preview address; the user opens the webpage preview address on the computer, the first page of the file is quickly loaded, and the auxiliary thread created by the asynchronous transcoding program continues to load subsequent content in the background. According to the method, the user is responded when the request is received, and the user can preview the request in advance, so that the concurrency efficiency is improved.

Description

technical field [0001] The invention relates to a method for realizing instant preview of files, in particular to a method for realizing instant preview of files based on JAVA multi-process and multi-thread. Background technique [0002] When we use a browser to open a web page document for preview, the loading time of the document is relatively long, especially when encountering a document with a large number of pages, the loading speed of the web page is even slower. This phenomenon is mainly related to the current situation. It is related to the transcoding method of the document at this stage. The document transcoding method at this stage is synchronous transcoding, that is, it must wait for all pages of the document to be transcoded in the background before returning to the user’s preview address. At this time, the webpage opened by the user will After the loading is complete, the preview interface is displayed, which means that the longer the document pages, the longer...

[0002] When we use a browser to open a web page document for preview, the loading time of the document is relatively long, especially when encountering a document with a large number of pages, the loading speed of the web page is even slower. This phenomenon is mainly related to the current situation. It is related to the transcoding method of the document at this stage. The document transcoding method at this stage is synchronous transcoding, that is, it must wait for all pages of the document to be transcoded in the background before returning to the user’s preview address. At this time, the webpage opened by the user will After the loading is complete, the preview interface is displayed, which means that the longer the document pages, the longer the loading time. This transcoding method makes the user's experience bad, and the long loading time also affects the information acquisition time and delays reading study time
