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 argument. Pass a pointer to a linked list of curl_httppost structs as parameter. The easiest way to create such a list, is to use curl_formadd(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_NOBODY(3) to 0.

This option is deprecated! Do not use it. Use CURLOPT_MIMEPOST(3) instead after having prepared mime data.

DEFAULT

NULL

PROTOCOLS

HTTP

EXAMPLE

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

the given file name when curl_easy_perform() is called. */ curl_formadd(&formpost,
&lastptr,
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.

RETURN VALUE

Returns CURLE_OK if HTTP is enabled, and CURLE_UNKNOWN_OPTION if not.
