我整个上午都有一个问题一直困扰着我。
我希望通过CURL获取所有http标头...并找出,如果pinged url是否已压缩。 (以下任一项:gzip / x-gzip / deflate / compress)
但我从CURL得到的只是:
[url] => http://www.url
[content_type] => text/html; charset=UTF-8
[http_code] => 302
[header_size] => 764
[request_size] => 54
[filetime] => -1
[ssl_verify_result] => 0
[redirect_count] => 0
[total_time] => 0.042535
[namelookup_time] => 0.002779
[connect_time] => 0.014986
[pretransfer_time] => 0.015039
[size_upload] => 0
[size_download] => 0
[speed_download] => 0
[speed_upload] => 0
[download_content_length] => 218
[upload_content_length] => 0
[starttransfer_time] => 0.042204
[redirect_time] => 0`
Nothnig喜欢"内容编码" ......有机会通过PHP获得这个吗?

您必须从curl获取标头并为Content-Encoding
标头解析它们。
以下是一个例子:
<?php
$ch = curl_init("http://stackoverflow.com/");
curl_setopt($ch,CURLOPT_HTTPHEADER,array('Accept-Encoding: gzip, deflate'));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$buffer = curl_exec($ch);
$curl_info = curl_getinfo($ch);
curl_close($ch);
$header_size = $curl_info["header_size"];
$headers = substr($buffer, 0, $header_size);
$body = substr($buffer, $header_size);
function getEncoding(&$headers){
$arr=explode("\r\n",trim($headers));
array_shift($arr);
foreach($arr as $header){
list($k,$v)=explode(':',$header);
if ('content-encoding'==strtolower($k)){
return trim($v);
}
}
return false;
}
$encoding=getEncoding($headers);
if ($encoding) {
echo "Using: ".$encoding;
}else{
echo "None";
}
?>
