(1) principle
The thief program actually invokes the webpage on other websites through the XMLHTTP components in XML. For example, the news thief program, many of them call the Sina's news page, and some replacements are made, and the advertisements have also been filtered. The advantages of the thief program are: No need to maintain the website, because the data in the thief program is from other websites, which will be updated with the update of the site; save server resources, general thief procedures, all web content is From other websites. Disadvantages: Unstable, if the target website is wrong, the program will make an error, and if the target website is upgraded, then the thieves should be modified accordingly; speed, because it is remote call, speed, and read data on the local server Compared to, it must be slower.
