CodeIgniter实现从网站抓取图片并自动下载到文件夹里的方法,codeigniter抓取

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。。。

<&#63;php
$imageslist = phpQuery::newDocumentFile('http://g.e-hentai.org/g/xxxxx/xxxxxxx/');
//首页
$pn = 1;//页数
$ps = $imageslist->find('.ptt td a');//从首页抓页面导航
//从页面导航开始获取页面内容
foreach($ps as $p)
{
  echo '第'.$pn++.'页:<a href="'.pq($p)->attr("href").'"/></br>';
  $imagesnow = phpQuery::newDocumentFile(pq($p)->attr("href"));
  //单页内容
  $images = $imagesnow->find('#gdt a');//抓取图片页列表
  foreach($images as $image)
  {
    echo '<a href="'.pq($image,$imagesnow)->attr("href").'"/></br>';
    $imagebigs = phpQuery::newDocumentFile(pq($image,$imagesnow)->attr("href"));
    //获取单图片页地址
    echo '<img  src="'.$imagebigs- alt="CodeIgniter实现从网站抓取图片并自动下载到文件夹里的方法,codeigniter抓取" >find('#i3 img')->attr('src').'"></br>';//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);
  }
}
&#63;>

希望本文所述对大家基于CodeIgniter的php程序设计有所帮助。
