php curl设置自定义请求头和打印请求头信息

$header = [
 'client:h5',
 'token:test',
];
curlRequest($url, $params, true, 10, $header);

PHP5.1.3版以上支持用curl_getinfo函数来获取请求头

具体需要先设置 curl_setopt($ch, CURLINFO_HEADER_OUT, true);

然后在请求发生后用 curl_getinfo($ch, CURLINFO_HEADER_OUT);

 function curlRequest($url, $params = array(), $is_post = false, $time_out = 10, $header=array())
 {
 $str_cookie = isset($ext_params['str_cookie']) ? $ext_params['str_cookie'] : '';$ch = curl_init();//初始化curl
 curl_setopt($ch, CURLOPT_URL, $url);//抓取指定网页
 curl_setopt($ch, CURLOPT_HEADER, 0);//设置是否返回response header
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
 //当需要通过curl_getinfo来获取发出请求的header信息时，该选项需要设置为true
 curl_setopt($ch, CURLINFO_HEADER_OUT, true);
 curl_setopt($ch, CURLOPT_TIMEOUT, $time_out);
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $time_out);
 curl_setopt($ch, CURLOPT_POST, $is_post);
 if ($is_post) {
 curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
 }
 if ($str_cookie) {
 curl_setopt($ch, CURLOPT_COOKIE, $str_cookie);
 }
 if ($header) {
 curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
 }
 $response = curl_exec($ch);
　　　　　//打印请求的header信息
 $request_header = curl_getinfo( $ch, CURLINFO_HEADER_OUT);
 print_r($request_header);
 curl_close($ch);
 return $response;
 }
