Design Idea
Considering that it is too troublesome to simply collect pictures from a web page, we directly collect its list page, get the URL of the list and then collect them one by one, but use PHP to match the list The URL of the page is too troublesome. There are many invalid URLs on the first list page, which is really a problem for me, a newbie with regular expressions. After looking at the structure of the list page, I decided to use jquery to obtain the URL. The universal selector of jquery has become powerful again.
jquery gets the url, and then ajax passes the url—> Corresponding PHP file, traverses url parameters—-> Single page collection and saving images
