CURLOPT_HTTPPOST(3) curl_easy_setopt options CURLOPT_HTTPPOST(3)
NAME
CURLOPT_HTTPPOST - multipart formpost content
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST,
struct curl_httppost *formpost);
DESCRIPTION
Tells libcurl you want a multipart/formdata HTTP POST to be made and
you instruct what data to pass on to the server in the formpost argu-
ment. Pass a pointer to a linked list of curl_httppost structs as pa-
rameter. The easiest way to create such a list, is to use curl_for-
madd(3) as documented. The data in this list must remain intact as long
as the curl transfer is alive and is using it.
Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue"
header. You can disable this header with CURLOPT_HTTPHEADER(3).
When setting CURLOPT_HTTPPOST(3), it will automatically set CURLOPT_NO-
BODY(3) to 0.
This option is deprecated! Do not use it. Use CURLOPT_MIMEPOST(3) in-
stead after having prepared mime data.
DEFAULT
NULL
PROTOCOLS

EXAMPLE
/* Fill in the file upload field. This makes libcurl load data from

CURLFORM_COPYNAME, "sendfile",
CURLFORM_FILE, "postit2.c",
CURLFORM_END);
/* Fill in the filename field */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "filename",
CURLFORM_COPYCONTENTS, "postit2.c",
CURLFORM_END);
/* Fill in the submit field too, even if this is rarely needed */
curl_formadd(&formpost,
&lastptr,
CURLFORM_COPYNAME, "submit",
CURLFORM_COPYCONTENTS, "send",
CURLFORM_END);
AVAILABILITY
As long as HTTP is enabled. Deprecated in 7.56.0.
