CURL in php gets request headers and response headers

This article mainly shares with you CURL in php to obtain request headers and response headers, hoping to help everyone.

1. Get the response header from CURL

$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($oCurl, CURLOPT_NOBODY, true);
// 使用上面定义的 ua
curl_setopt($oCurl, CURLOPT_USERAGENT,$user_agent);
curl_setopt($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);
    
curl_close($oCurl);

2. Get the request header from curl

$oCurl = curl_init();
 curl_setopt($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);
