本文实例讲述了CodeIgniter实现从网站抓取图片并自动下载到文件夹里的方法。分享给大家供大家参考。具体如下:
因为某网站看图比较坑爹,要一页一页的翻页。。。。所以。。。。就写了这么个东西
(我是产品不是程序员)运行速度简直无法忍受,,而且经常会有错误发生,所以希望大家帮忙改进(PHP)。
当然也欢迎看到PYTHON,GOLANG的版本~~^_^
1. controllers:
$this->load->helper('date'); $this->load->helper('phpQuery'); //我是把phpQuery单文件放到helper里了
2. view:
这里只是为了快速出产品,所以直接在VIEW里写的代码,请无视变量名。。。
find('.ptt td a');//从首页抓页面导航
//从页面导航开始获取页面内容
foreach($ps as $p)
{
echo '第'.$pn++.'页:';
$imagesnow = phpQuery::newDocumentFile(pq($p)->attr("href"));
//单页内容
$images = $imagesnow->find('#gdt a');//抓取图片页列表
foreach($images as $image)
{
echo '';
$imagebigs = phpQuery::newDocumentFile(pq($image,$imagesnow)->attr("href"));
//获取单图片页地址
echo '';//输出图片
ob_start();
readfile($imagebigs->find('#i3 img')->attr('src'));
$img = ob_get_contents();
ob_end_clean();
$filename='img/'.now().'.jpg';
$f=fopen($filename,'a');
fwrite($f,$img);
fclose($f);
}
}
?>
希望本文所述对大家基于CodeIgniter的php程序设计有所帮助。
