使用cURL脚本复制img时出错(php)
我做了一个很好的简单的userscript:
当我浏览网页时,我可以通过单击“书签”任何图像
我的用户
一切正常,但在某些情况下,脚本无法复制文件...
实际上文件已创建,但不包含img数据,它只包含错误网页的内容:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>403 Forbidden</title>
</head><body>
<h1>Forbidden</h1>
<p>You don't have permission to access /data/x/xxx_xxx_x.jpg on this server.</p>
<p>Additionally, a 403 Forbidden
error was encountered while trying to use an ErrorDocument to handle the request.</p>
<hr>
<address>Apache Server at xxxxxxxx.net Port 80</address>
</body></html>
“复制”代码(php):
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $urlimg);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
set_time_limit(300); # 5 minutes for PHP
curl_setopt($ch, CURLOPT_TIMEOUT, 300); # and also for CURL
$path = $dirpix.'/'.$aa.'/'.$mm;
if ( ! is_dir($path)) {
mkdir($path);
}
$outfile = fopen($path.'/'.$id.'.'.$ext, 'wb');
curl_setopt($ch, CURLOPT_FILE, $outfile);
curl_exec($ch);
fclose($outfile);
curl_close($ch);
也许该网站阻止那种“复制”脚本? 谢谢!
我能想到的两件事情是,
将用户代理设置为卷曲请求。 因为根据你的说法,你可以查看图像,但curl得到了403错误,很可能是服务器端的userAgent过滤。
添加referer到你的curl请求。 您可以将引用者信息从您的脚本发送到php脚本。 你必须发布或获取window.location.href
的值。
尝试下面的代码,它在我的服务器上正常工作。 它是测试代码: -
<?php
$img[]='http://i.indiafm.com/stills/celebrities/sada/thumb1.jpg';
$img[]='http://i.indiafm.com/stills/celebrities/sada/thumb5.jpg';
$path="images/";
foreach($img as $i){
save_image($i, $path);
if(getimagesize($path.basename($i))){
echo '<h3 style="color: green;">Image ' . basename($i) . ' Downloaded OK</h3>';
}else{
echo '<h3 style="color: red;">Image ' . basename($i) . ' Download Failed</h3>';
}
}
//Alternative Image Saving Using cURL seeing as allow_url_fopen is disabled - bummer
function save_image($img,$fullpath='basename'){
if($fullpath!='basename'){
$fullpath = $fullpath.basename($img);
}
$ch = curl_init ($img);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$rawdata=curl_exec($ch);
curl_close ($ch);
if(file_exists($fullpath)){
unlink($fullpath);
}
$fp = fopen($fullpath,'x');
fwrite($fp, $rawdata);
fclose($fp);
}
为正确的工作添加
$agent= 'Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11';
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
