.TH CURLOPT_HTTPPOST 3 "2024-06-01" libcurl
|
|
.SH NAME
|
|
CURLOPT_HTTPPOST \- multipart formpost content
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST,
|
|
struct curl_httppost *formpost);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
\fBThis option is deprecated.\fP Use \fICURLOPT_MIMEPOST(3)\fP instead.
|
|
|
|
Tells libcurl you want a \fBmultipart/formdata\fP HTTP POST to be made and you
|
|
instruct what data to pass on to the server in the \fIformpost\fP argument.
|
|
Pass a pointer to a linked list of \fIcurl_httppost\fP structs as parameter.
|
|
The easiest way to create such a list, is to use \fIcurl_formadd(3)\fP 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 \fICURLOPT_HTTPHEADER(3)\fP.
|
|
|
|
When setting \fICURLOPT_HTTPPOST(3)\fP, libcurl automatically sets
|
|
\fICURLOPT_NOBODY(3)\fP to 0.
