但另一台服务器正常返回内容。。

$URL = http://www.youtube.com/get_video_info?&video_id='.$this->VideoId.'&asv=3&el=detailpage&hl=en_US

function curlGet($URL) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; rv:19.0) Gecko/20100101 Firefox/19.0');
curl_setopt($ch, CURLOPT_URL, $URL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5); 
$contents = curl_exec($ch);
if(curl_errno($ch)) {
    echo ' er: ' . curl_error($ch)  ;
}
    // get content
    echo $contents ;
    curl_close($ch);
}

设置选项以查看请求和响应标头
如果您的url被重定向，最好包含CURLOPT_FOLLOWLOCATION

这样的东西会帮助发现问题。
