NAME

CURLOPT_HTTPPOST - multipart formpost content

SYNOPSIS

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST,
struct curl_httppost *formpost);

DESCRIPTION

This option is deprecated. Use CURLOPT_MIMEPOST(3) instead. 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), libcurl automatically sets CURLOPT_NOBODY(3) to 0.

DEFAULT

NULL

PROTOCOLS

This functionality affects http only

EXAMPLE

int main(void)
{
struct curl_httppost *formpost;
struct curl_httppost *lastptr;
/* 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);
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_HTTPPOST, formpost);
curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
curl_formfree(formpost);
}

DEPRECATED

Deprecated in 7.56.0.

AVAILABILITY

Added in curl 7.1

RETURN VALUE

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