Abstract

The invention relates to a method, device and system for displaying an alarm file, and belongs to the field of communication. The method comprises the following steps: receiving a data packet corresponding to an alarm file sent by a server through long connection with the server, wherein the server releases storage resources occupied by the alarm file after sending the alarm file; analyzing the data packet corresponding to the alarm file to acquire the alarm file; generating a uniform resource locator URL of the alarm file; and displaying the alarm file according to the URL of the alarm file.According to the invention, waste of storage resources of the server can be reduced.

Description

technical field [0001] The present application relates to the communication field, in particular to a method, device and system for displaying alarm files. Background technique [0002] In the security industry, the browser can be used to request alarm pictures from the server, and the alarm pictures can be displayed through the browser. The alarm picture is a kind of alarm file. After obtaining the alarm picture, the server first saves the alarm picture for browser request. [0003] At present, the browser can request the alarm picture from the server in a polling manner, that is, the browser sends a request message to the server at intervals, and the server receives the request message. If the alarm picture is currently saved, it sends the message to the browser. The uniform resource locator URL of the alarm picture. The browser obtains the original data of the picture through the URL of the alarm picture and parses it into an alarm picture displayed by normal pixels; if ...
