. . . . Because a certain website is a bit tricky to view pictures, and you have to turn page after page. . . . so. . . . I just wrote something like this
(I am a product, not a programmer). The running speed is simply unbearable, and errors often occur, so I hope everyone can help improve it (PHP). . .
Of course, you are also welcome to see the PYTHON and GOLANG versions~~^_^
By the way, the program is based on CodeIgniter
. . . . Click links carefully
  1. $this->load->helper('date');
  2. $this->load->helper('phpQuery');
  3. //I put the phpQuery single file into the helper
Copy code
  1. //- - Just to quickly produce products, so please ignore the variable names when writing code directly in VIEW. . .
  2. $imageslist = phpQuery::newDocumentFile('http://g.e-hentai.org/g/xxxxx/xxxxxxx/');//Homepage
  3. $pn = 1;//Number of pages
  4. $ps = $imageslist->find('.ptt td a');//Get the page navigation from the homepage
  5. //Get the page content starting from the page navigation
  6. foreach($ps as $p)
  7. {
  8. echo 'th'. $pn++.'Page:
    ';
  9. $imagesnow = phpQuery::newDocumentFile( pq($p)->attr("href"));//Single page content
  10. $images = $imagesnow->find('#gdt a');//Catch the image page list
  11. foreach($ images as $image)
  12. {
  13. echo '
    ';
  14. $ imagebigs = phpQuery::newDocumentFile(pq($image,$imagesnow)->attr("href"));//Get the address of a single image page
  15. echo '
    ';//Output image
  16. ob_start();
  17. readfile($imagebigs->find('#i3 img')->attr('src'));
  18. $img = ob_get_contents();
  19. ob_end_clean();
  20. $filename='img/'.now().'.jpg';
  21. $f=fopen ($filename,'a');
  22. fwrite($f,$img);
  23. fclose($f);
  24. }
  25. }
  26. ?>
