2) script tag is converted into noscript to prevent execution;
3) relative path setting in href, SRC, CSS is absolute path
4) Each Node is provided with a unique ID.
The data conversion step comprises: the change of the DOM is monitored by using the MutationObserver API, the changed DOM is generated into a snapshot, a timestamp is recorded, the snapshot is finally recorded into a large array, each item is data of each frame of the page change, and simultaneously, actions such as a click event or mouse movement and the like are recorded independently (as shown in fig. 1).
The question feedback step comprises: the page information is obtained by recording the screen of the front end, and quantitative data of the page information in a period of time before the problem occurs is sent to the background so as to monitor page change in a period of time before the problem occurs.
The restoring and playing step comprises the following steps: and according to the quantitative data fed back in the problem feedback step, creating a DOM (document object model) and a corresponding CSS (cascading style sheet), putting the DOM and the corresponding CSS in an iframe as a player, restoring the change of the DOM by the background second according to a time stamp, and adjusting the frame and the speed to be seen at the moment through the time stamp in the data.
The invention provides a web front-end monitoring system based on screen recording playback, wherein the monitoring system acquires page information by recording a screen at a front end, transmits the page information within a period of time before a problem occurs to a background, and the background restores the page information and plays the page information in a video mode.
In this embodiment, the monitoring system includes the following modules: the snapshot generating module is used for storing the DOM of the page at intervals and generating snapshots; the data conversion module is used for recording the front-end page operation information, converting the front-end page operation information into quantitative data with time stamps together with the page snapshot and recording the quantitative data; the problem feedback module is used for uploading the quantitative data in a period of time before the problem occurs to a background when the page has the problem; and the restoring and playing module is used for restoring the obtained data into a video in a timestamp mode in the background and playing the video.
