Webpage printing method based on analysis plug-in, server and storage medium

Abstract

The invention discloses a webpage printing method based on an analysis plug-in. The method is applied to a server. The method comprises the steps of receiving first to-be-printed area data including ahypertext marking text and a webpage style file, calling an html parsing engine in the parsing plug-in to parse and convert the label data in the hypertext markup text into dom nodes; constructing adom tree according to the dom nodes; calling a css parser to parse the webpage style file to obtain a style rule; and constructing a render tree based on the dom tree and the style rule, constructinga virtual drawing context based on the constructed render tree, generating vector image data from the virtual drawing context, converting the vector image data into a to-be-printed image file, and sending the to-be-printed image file to a printing terminal for webpage printing. According to the method, the compatibility problem caused by non-uniform kernel or internal version of the browser of theuser is avoided, and the situation that the browser crashes due to the fact that the maximum bearing capacity of the browser is exceeded when a large amount of webpage data needs to be printed at thesame time can also be avoided.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a web page printing method based on an analysis plug-in, a server and a storage medium. Background technique [0002] With the continuous development of network technology, data storage and management on the network has become a daily choice for people, and webpage printing is one of the many methods to obtain data from the webpage. [0003] At present, most webpage printing methods use the html parsing engine of the browser itself to analyze the html data of the webpage data to be printed, and generate a format file supported by the printer to complete the printing of the webpage data to be printed. However, when a large amount of webpage data needs to be printed at the same time, the browser will crash due to exceeding the maximum load capacity of the browser, which will affect the printing of webpage data, and there is room for improvement.
