How to obtain CURL request headers and response headers in php

$oCurl = curl_init();
// 设置请求头, 有时候需要,有时候不用,看请求网址是否有对应的要求$header[] = "Content-type: application/x-www-form-urlencoded";$user_agent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36";
curl_setopt($oCurl, CURLOPT_URL, $sUrl);
curl_setopt($oCurl, CURLOPT_HTTPHEADER,$header);
// 返回 response_header, 该选项非常重要,如果不为 true, 只会获得响应的正文curl_setopt($oCurl, CURLOPT_HEADER, true);
// 是否不需要响应的正文,为了节省带宽及时间,在只需要响应头的情况下可以不要正文curl_setopt($oCurl, CURLOPT_NOBODY, true);// 使用上面定义的 uacurl_setopt($oCurl, CURLOPT_USERAGENT,$user_agent);

//curl_setopt($oCurl, CURLOPT_REFERER,'http://www.baidu.com');设置referer
curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1 );
// 不用 POST 方式请求, 意思就是通过 GET 请求curl_setopt($oCurl, CURLOPT_POST, false);$sContent = curl_exec($oCurl);
// 获得响应结果里的：头大小$headerSize = curl_getinfo($oCurl, CURLINFO_HEADER_SIZE);
// 根据头大小去获取头信息内容$header = substr($sContent, 0, $headerSize);

// 获得响应结果里的：响应状态码

$httpCode = curl_getinfo($oCurl, CURLINFO_HTTP_CODE);

curl_close($oCurl);

$oCurl = curl_init();
 curl_setopt($oCurl, CURLOPT_URL, "https://117.28.240.235:8002/ipcc/agent/login");
 curl_setopt($oCurl, CURLOPT_HTTPHEADER, $header);//关闭https验证
 curl_setopt($oCurl, CURLOPT_SSL_VERIFYPEER, false);
 curl_setopt($oCurl, CURLOPT_SSL_VERIFYHOST, false);//至关重要，CURLINFO_HEADER_OUT选项可以拿到请求头信息curl_setopt($oCurl, CURLINFO_HEADER_OUT, TRUE);
curl_setopt($oCurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($oCurl, CURLOPT_POST, 1);
curl_setopt($oCurl, CURLOPT_POSTFIELDS, $bodystr);$sContent = curl_exec($oCurl);//通过curl_getinfo()可以得到请求头的信息$a=curl_getinfo($oCurl);
