Embodiment 1

[0025] combined with figure 1 As shown, an anti-reptile method based on the separation of the front and rear ends, the method includes the following steps:

[0026] First, the front end determines the HTML webpage, and the source HTML webpage is the HTML webpage normally compiled by the website staff. The source HTML web page includes multiple tag structures, and each tag includes valid data that needs to be displayed to the user. Such as:

[0027] ......... and other page structure

[0028] Then, the back-end calls the interface to obtain data from the database, and transfers the data with HTML structure tag transfer characters, such as: {title:'";\u003Cdiv\u003E\u003Cdiv and Huawei promote the ultra-high-definition standard, and Changhong has three advantages'" ;\u003Cdiv\u003E\u003Cdivslice(6,-6),Content:'";\u003Cdiv\u003E\u003Cdivclass=;\";pgc-img\";\u003E\u003Cimgsrc=;\";http:\u002F\ u002Fp1.pstatp.com\u002Flarge\u002Fpgc-image\u002F0e8e39f761174f84b4d16418b0...

Abstract

The invention discloses an anti-crawler method based on front-end and rear-end separation development. The method comprises the following steps:1, a front end constructing a source HTML webpage whichcomprises normal data displayed to a user and a label structure containing protected data; 2, a rear-end program calling a service layer to run a service code to extract data needing to be displayed,and preprocessing the extracted data; and 3, performing front-end and rear-end interaction, using a JSON format for data transmission, and the front end decrypting the data after acquiring the data and then displaying the data on an HTML page.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular, it is an anti-crawler method based on the separate development of the front and back ends. Background technique [0002] In recent years, the Internet has gradually shifted to the direction of big data. In the big data environment, data acquisition is very important. In the method of data acquisition, crawler technology is usually used for data capture. In order to protect one's own web page content in a big data environment, it is necessary to perform anti-crawling processing on crawlers. The struggle between crawling and anti-crawling has never stopped. The previous primary crawlers screened header information, and tested and improved the crawler program by constantly fighting against anti-crawling. After technological advancement, crawlers can: imitate human behavior, load Javascript and external resources, simulate cookies and useragent, automate browser operations,...
