Thanks for the answer upstairs. It should not be a problem with anti-leeching. It seems that the DOM rules cannot determine the attributes of data-src and src when crawling. After researching for a long time, I found that simple_html_dom is indeed a good thing, and it should be possible to replace it after crawling it back. Unfortunately, because I am not very familiar with PHP, the statements are always written incorrectly. Later, I used js native methods to save the country, obtained the contents of php variables and replaced them with regular rules to solve the problem.
In addition, after using html_dom, don’t forget $html->clear.

Modify curl header parameters and try it
