CURLOPT_POST(3) 					     curl_easy_setopt options						   CURLOPT_POST(3)

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  CUR-
       LOPT_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-encod-
       ing  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.

DEFAULT

       0, disabled
