试图通过卷曲发布后从一个页面抓取数据

Question

我试图从这里抓取数据：http://mediaforest.biz/mobile/nowplaying.aspx 在页面中选择一个站点并发布它然后您将获得带有数据的新页面。但我不能抓住它，我再次获得相同的页面。

我用这个代码：

<?php 
header ('Content-type: text/html; charset=utf-8'); 

$url = "http://mediaforest.biz/mobile/nowplaying.aspx"; 
$referer = ""; 

// headers 
$header[] = "Host: ".parse_url($url, PHP_URL_HOST); 
$header[] = "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; he; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3"; 
$header[] = "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; 
$header[] = "Accept-Language: he,en-us;q=0.7,en;q=0.3"; 
$header[] = "Accept-Encoding: gzip,deflate"; 
$header[] = "Accept-Charset: windows-1255,utf-8;q=0.7,*;q=0.7"; 
$header[] = "Keep-Alive: 115"; 
$header[] = "Connection: keep-alive"; 

$cookie="cookie.txt"; 
$fp=fopen($cookie,"w+"); 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch,CURLOPT_REFERER,$referer); 
curl_setopt($ch, CURLOPT_TIMEOUT, 900); 
curl_setopt($ch, CURLOPT_FAILONERROR, false); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $header); 
curl_setopt($ch, CURLOPT_HEADER,true); 
curl_setopt($ch, CURLOPT_COOKIEFILE,$cookie); 
curl_setopt($ch, CURLOPT_COOKIEJAR,$cookie); 
curl_setopt($ch, CURLOPT_VERBOSE, 0); 

$content=curl_exec($ch); 
echo $content; 

    if(stristr($content,"__EVENTTARGET")){ 
     $array1=explode('__EVENTTARGET" value="',$content); 
     $content1=$array1[1]; 
     $array2=explode('"> 
<input type="hidden" name="__EVENTARGUMENT"',$content1); 
     $content2=$array2[0]; 
     $EVENTTARGET=urlencode($content2); 
    } 

    if(stristr($content,"__EVENTARGUMENT")){ 
     $array1=explode('__EVENTARGUMENT" value="',$content); 
     $content1=$array1[1]; 
     $array2=explode('"> 
<script language',$content1); 
     $content2=$array2[0]; 
     $EVENTARGUMENT=urlencode($content2); 
    } 

    if(stristr($content,"formNowPlaying")){ 
     $array1=explode('method="post" action="',$content); 
     $content1=$array1[1]; 
     $array2=explode('"> 
<input type="hidden" name="__EVENTTARGET"',$content1); 
     $content2=$array2[0]; 
     $nexturl=$content2; 
    } 

//echo $EVENTTARGET." ".$EVENTARGUMENT." ".$nexturl; 

$url = "http://mediaforest.biz/mobile/".$nexturl; 

$fields = "EVENTTARGET=".$EVENTTARGET."&__EVENTARGUMENT=".$EVENTARGUMENT."&MyChannels=0&ViewChannel_Button=Show"; 

curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch,CURLOPT_REFERER,$referer); 
curl_setopt($ch, CURLOPT_TIMEOUT, 900); 
curl_setopt($ch, CURLOPT_FAILONERROR, false); 
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $header); 
curl_setopt($ch, CURLOPT_HEADER,true); 
curl_setopt($ch, CURLOPT_COOKIEFILE,$cookie); 
curl_setopt($ch, CURLOPT_COOKIEJAR,$cookie); 
curl_setopt($ch, CURLOPT_VERBOSE, 1); 

$content_stage2=curl_exec($ch); 
echo $content_stage2; 
?> 

Answer 1

我没有与卷曲太多的经验，我没有看进去，但乍一看似乎这样的：

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false); 

需要这个：

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 

虽然可能是错误的。

Answer 2

如果您从第一个请求获取数据，请尝试关闭（针对每个请求）。

$content=curl_exec($ch); 
curl_close($ch); 
echo $content; 

和

$content_stage2=curl_exec($ch); 
curl_close($ch);  
echo $content_stage2;
