PHP采集静态页面并把页面css,img,js保存的方法,静态页面css
本文实例讲述了PHP采集静态页面并把页面css,img,js保存的方法。分享给大家供大家参考。具体分析如下:
这是一个可以获取网页的html代码以及css,js,font和img资源的小工具,主要用来快速获取模板,如果你来不及设计UI或者看到不错的模板,则可以使用这个工具来抓取网页和提取资源文件,提取的内容会按相对路径来保存资源,因此你不必担心资源文件的错误url导入.
首页 index.php,代码如下:
复制代码 代码如下:
Web Grabber
Url
Save All
List
抓取页面代码 grab.php,代码如下:
复制代码 代码如下:
/*
* flute
* 2014/03/31
*/
if(isset($_POST['url'])) {
if(isset($_POST['project']) && !is_dir($_POST['project'])) mkdir($_POST['project'], 0777);
echo json_encode(grab($_POST['url']));
}
function grab($url) {
//$url = 'http://ldixing-wordpress.stor.sinaapp.com/uploads/leaves/test.html';
$data = array();
$file = preg_replace('/^.*//', '', $url);
if(($content = file_get_contents($url)) !== false) {
if(isset($_POST['project'])) file_put_contents($_POST['project'].'/'.$file, $content);
$pattern = '/
if(preg_match_all($pattern, $content, $matches)) {
$data['css'] = $matches[2];
}
$pattern = '/
if(preg_match_all($pattern, $content, $matches)) {
$data['js'] = $matches[2];
}
$pattern = '//i';
if(preg_match_all($pattern, $content, $matches)) {
$data['img'] = $matches[2];
}
$pattern = '/url(('|"|s)(.*?)1)/i';
if(preg_match_all($pattern, $content, $matches)) {
$data['src'] = $matches[2];
}
}
return $data;
}
function vardump($obj) {
echo '
'; <br> print_r($obj); <br> echo '';
}
?>
保存css,js,img等资源的页面 save.php,代码如下:
复制代码 代码如下:
/*
* flute
* 2014/03/31
*/
if(isset($_POST['url']) && isset($_POST['project']) && isset($_POST['domain'])) {
extract($_POST);
$url = preg_replace('/?.*$/', '', $url);
$file = $url;
$arr = explode('/', $file);
$length = sizeof($arr);
$filename = $arr[$length - 1];
$root = $project;
$dir = $root;
if($domain == 'http') {
$dir = $root.'/http';
if(!is_dir($dir)) mkdir($dir, 0777);
} else {
$file = $domain.'/'.$url;
for($i = 0; $i
if(!emptyempty($arr[$i])) {
$dir .= '/'.$arr[$i];
if(!is_dir($dir)) mkdir($dir, 0777);
}
}
}
if(!file_exists($dir.'/'.$filename) || filesize($dir.'/'.$filename) == 0) {
$content = file_get_contents($file);
file_put_contents($dir.'/'.$filename, $content);
}
}
?>
使用方法:
1. 打开index页,输入项目名和要抓取的网址,网址必须是文件名结尾,如index.html;
2. 点Get按钮,得到当前页面所有的css,js,img等资源列表;
3. 点击css链接会获取css文件中的背景资源图片,附加在列表后头;
4. 点击Save All即可保存列表中所有的文件,并按相对路径生成;
5. 如果网页上有http远程文件,将会直接保存在http文件夹下;
6. Get和Save有时会失败,没关系重试几次即可。
希望本文所述对大家的php程序设计有所帮助。
