NAME

       CURLOPT_POST - request a HTTP POST

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POST, long post);

DESCRIPTION

       A  parameter  set  to  1  tells libcurl to do a regular HTTP post. This will also make the
       library use a "Content-Type: application/x-www-form-urlencoded" header. (This  is  by  far
       the most commonly used POST method).

       Use one of CURLOPT_POSTFIELDS(3) or CURLOPT_COPYPOSTFIELDS(3) options to specify what data
       to post and CURLOPT_POSTFIELDSIZE(3) or CURLOPT_POSTFIELDSIZE_LARGE(3)  to  set  the  data
       size.

       Optionally,   you   can  provide  data  to  POST  using  the  CURLOPT_READFUNCTION(3)  and
       CURLOPT_READDATA(3) options but then you must make sure to not  set  CURLOPT_POSTFIELDS(3)
       to  anything  but  NULL.  When  providing data with a callback, you must transmit it using
       chunked  transfer-encoding  or  you  must  set   the   size   of   the   data   with   the
       CURLOPT_POSTFIELDSIZE(3)  or  CURLOPT_POSTFIELDSIZE_LARGE(3)  options.  To  enable chunked
       encoding, you simply pass in the  appropriate  Transfer-Encoding  header,  see  the  post-
       callback.c example.

       You  can  override  the  default  POST  Content-Type:  header  by  setting  your  own with
       CURLOPT_HTTPHEADER(3).

       Using POST with HTTP 1.1 implies the use of a  "Expect:  100-continue"  header.   You  can
       disable this header with CURLOPT_HTTPHEADER(3) as usual.

       If  you  use  POST to a HTTP 1.1 server, you can send data without knowing the size before
       starting the POST if you use chunked encoding. You enable this by  adding  a  header  like
       "Transfer-Encoding:  chunked" with CURLOPT_HTTPHEADER(3). With HTTP 1.0 or without chunked
       transfer, you must specify the size in the request.

       When setting CURLOPT_POST(3) to 1, it will automatically set CURLOPT_NOBODY(3) to 0.

       If you issue a POST request and then want to make a HEAD or GET  using  the  same  re-used
       handle,  you  must  explicitly  set  the  new  request  type  using  CURLOPT_NOBODY(3)  or
       CURLOPT_HTTPGET(3) or similar.
