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), it will automatically set CURLOPT_NOBODY(3) to 0.

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.
