man curl:

   -H/--header <header>
          (HTTP)  Extra header to use when getting a web page. You may specify
          any number of extra headers. Note that if you should  add  a  custom
          header that has the same name as one of the internal ones curl would
          use, your externally set header will be used instead of the internal
          one.  This  allows  you  to make even trickier stuff than curl would
          normally do. You should not replace internally set  headers  without
          knowing  perfectly well what you're doing. Remove an internal header
          by giving a replacement without content on the  right  side  of  the
          colon, as in: -H "Host:".

          curl  will  make sure that each header you add/replace get sent with
          the proper end of line marker, you should thus not  add  that  as  a
          part  of the header content: do not add newlines or carriage returns
          they will only mess things up for you.

          See also the -A/--user-agent and -e/--referer options.

          This option can be used multiple times to add/replace/remove  multi-
          ple headers.

Пример:

curl --header "X-MyHeader: 123" www.google.com

Вы можете увидеть запрос, который свернут, добавив параметр -v.

В PHP

curl_setopt($ch,CURLOPT_HTTPHEADER,array('HeaderName: HeaderValue'));

или вы можете установить несколько

curl_setopt($ch,CURLOPT_HTTPHEADER,array('HeaderName: HeaderValue','HeaderName2: HeaderValue2'));

Ответ 4

Используйте -H or --header.

Ответ 6

Я переключился с curl на Httpie; синтаксис выглядит так:

http http://myurl HeaderName:value

Ответ 7

Если вы хотите отправить свои пользовательские заголовки, вы можете сделать это таким образом

curl -v  -H @{'custom_header'='custom_header_value'} http://localhost:3000/action?result1=gh&result2=ghk
