Il y a de belles images sur Tumblr. Nous pouvons utiliser les API Tumblr pour rechercher et t\u00e9l\u00e9charger des images, mais cela n\u00e9cessite g\u00e9n\u00e9ralement l’enregistrement et les cl\u00e9s API. Une autre fa\u00e7on consiste \u00e0 explorer les pages Web HTML et \u00e0 analyser le DOM (Document Object Model)<\/a>, ce qui nous permet de r\u00e9cup\u00e9rer les URL des images et leurs descriptions.<\/p>\n

Il existe une biblioth\u00e8que pratique qui s’appelle PHPQuery. Cela nous permet d’\u00e9crire du PHP<\/a> de style JQuery de la m\u00eame mani\u00e8re que nous \u00e9crivons JQuery<\/a>, en utilisant des s\u00e9lecteurs CSS. Cela rend le PHP puissant pour analyser le DOM de toutes les pages HTML.<\/p>\n

requ\u00eate php<\/p>\n

Ce qui suit est un pseudo-code qui illustre comment analyser les pages HTML et saisir les images.<\/a><\/p>\n

Avec PHPQuery, il devient tellement plus simple d’analyser le DOM !<\/a> Cliquez pour tweeter<\/a><\/p>\n

require('phpQuery.php');\nrequire('app.php');\n\u00a0\n$ip = get_ip_address();\n\u00a0\nfunction grab($url, $lvl = 5) {\n\u00a0 global $ip;\n\u00a0 if ($lvl < = 0) {\n\u00a0 \u00a0 return;\n\u00a0 }\n\u00a0 $doc = phpQuery::newDocumentFile($url);\n\u00a0 foreach(pq('div.TumbPostPane') as $p) {\n\u00a0 \u00a0 \u00a0 $img = pq($p)->find('img.PhotoPostMainPhoto')->attr('src');\n\u00a0 \u00a0 \u00a0 $desc = htmlspecialchars(trim(pq($p)->find('div.MetaPanel')->html()));\n\u00a0 \u00a0 \u00a0 $url = pq($p)->find('a')->attr('href');\n\u00a0 \u00a0 \u00a0 $err = '';\n\u00a0 \u00a0 \u00a0 if (UploadPic($img, $desc, $err, $ip)) { \/\/ find pictures and save locally\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0echo \"OK = $err n\";\n\u00a0 \u00a0 \u00a0 } else {\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0echo str_replace(\"<br \/>\", \"n\", \"Error = $err n\");\n\u00a0 \u00a0 \u00a0 } \u00a0 \u00a0 \n\u00a0 \u00a0 \u00a0 grab($url, $lvl - 1); \/\/ recursive download\n\u00a0 }\n}\n\u00a0\ngrab(\"<a class=\"vglnk\" target=\"_blank\" href=\"https:\/\/uploadbeta.com\" rel=\"nofollow\"><span>https<\/span><span>:\/\/<\/span><span>uploadbeta<\/span><span>.<\/span><span>com<\/span><\/a>\", 1); <\/code><\/pre>\n
Avec peu de modifications, vous pouvez laisser le script explorer plusieurs milliers d’images en quelques minutes. Toutes les images sont enregistr\u00e9es dans des bases de donn\u00e9es locales sur le serveur VPS<\/a>. Les images peuvent \u00eatre vues sur: uploadbeta.com<\/a><\/p>\n
Il est pr\u00e9f\u00e9rable de d\u00e9finir un intervalle de temps entre les explorations de pages, sinon l’ adresse IP<\/a> risque d’\u00eatre bloqu\u00e9e.<\/p>\n
