PHP cURL获取动态内容

时间：2013-02-06 22:11:35

标签： php curl

我正在尝试使用cURL和PHP从网页上删除代理。但是，当我使用cURL时，我得到的是$ content中的CSS。该页面使用wordpress，因此它动态加载内容，但我没有找到任何东西来帮助我下载动态内容。我在linux中使用wget，页面下载很好。

    <?php
//$source1 = file_get_contents('http://www.new-fresh-proxies.blogspot.com/');
$source1 = get_data("http://www.new-fresh-proxies.blogspot.com/");

$array = array();
$source1 = preg_grep('/\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\:\d{1,5}\b/', $array);





//download webpage
function get_data($url) {
    $options = array(
            CURLOPT_RETURNTRANSFER => 1,     // return web page
            CURLOPT_HEADER         => true,    // don't return headers
            CURLOPT_FOLLOWLOCATION => true,     // follow redirects
            CURLOPT_ENCODING       => "",       // handle all encodings
            CURLOPT_USERAGENT      => "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13", // who am i
            CURLOPT_AUTOREFERER    => true,     // set referer on redirect
            CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
            CURLOPT_TIMEOUT        => 120,      // timeout on response
            CURLOPT_MAXREDIRS      => 50,       // stop after 10 redirects
    );

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    $header['errno']   = $err;
    $header['errmsg']  = $errmsg;
    $header['content'] = $content;
    return $header;

我的输出：

2 个答案:

答案 0 :(得分：2)

夫妻俩：

  • 你的'输出'来自哪里？我看到你的代码中没有显示......
  • 我还认为您的preg_grep声明不正确。您正在搜索空白数组并将结果保存到刚刚将数据提取到的变量中。尝试：

$array = preg_grep('/\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\:\d{1,5}\b/', $source1);

当我在$source1['content']电话后直接运行代码并转储get_data时，我收到了大量的IP地址......

答案 1 :(得分：1)

在我看来，你的Regexp是超时还是问题。

为什么不像你在第一时间那样坚持file_get_contents？

$content = file_get_contents('http://www.new-fresh-proxies.blogspot.com.au');

preg_match_all('/(\d+\.\d+\.\d+\.\d+(:\d+)?)/', $content, $matches);

print_r($matches[1]);

这将打印出IP列表：

Array
(
    [0] => 1.204.168.15:6673
    [1] => 1.234.45.130:80
    [2] => 1.34.163.101:8080
    [3] => 1.34.29.89:8080
    [4] => 1.34.8.221:3128
    ....

希望有所帮助。
