Method for capturing cloud calculating data from RIA (Rich Internet Application) page

Abstract

The invention discloses a method for capturing cloud calculating data from an RIA (Rich Internet Application) page. The method comprises the steps of: abstracting a target RIA page into a page model including at least one node tree; and then simulating a user operation to carry out ordered triggering on an event corresponding to a node in the page model, executing a corresponding code of the event, updating a DOM (Document Object Model) content of a page until the page model is traversed, finding out a path set included by the node tree in the page model, and storing the DOM content corresponding to each path. According to the method, through automatically triggering the event corresponding to the node and executing the corresponding code of the event, the DOM contents of the page are updated and nodes of a next layer are dynamically extended, the cloud calculating data from the RIA page are captured, and the method is high in capturing capability, low in occupation for system resources and good in application prospect.

Description

technical field [0001] The invention belongs to the technical field of web crawlers, in particular to a method for grabbing cloud computing data from RIA pages. Background technique [0002] With the development of the cloud computing industry, mature cloud computing products are emerging in the market one after another. The prosperity of the cloud computing industry has led to a rapid increase in the amount of information on cloud computing products on the Internet, and this information is scattered in the respective servers of each cloud computing manufacturer. superior. The data of cloud computing products is the key to the management and decision-making process in this field. How to obtain the data of cloud computing products scattered on the Internet is an important problem to be solved urgently. [0003] However, with the influx of a large number of cloud computing products into the market, the data of cloud computing products is also growing rapidly, and there are ma...

Problems solved by technology

However, the presentation of this new RIA model has brought huge challenges to services and applications whose main business is search engines, product comparison and recommendation, etc.

Due to the new RIA presentation method, the product page is required to adopt a large number of new scripting technologies including Ajax and jQuery in the front-end display, so that the traditional data capture technology cannot obtain useful data in the page, and cannot be compiled without obtaining these data Index for retrieval, not to mention product comparison and recommendation
