.TH CURLOPT_POSTFIELDS 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_POSTFIELDS \- specify data to POST to server
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDS, char *postdata);
|
|
.SH DESCRIPTION
|
|
Pass a char * as parameter, pointing to the full data to send in a HTTP POST
|
|
operation. You must make sure that the data is formatted the way you want the
|
|
server to receive it. libcurl will not convert or encode it for you in any
|
|
way. For example, the web server may assume that this data is url-encoded.
|
|
|
|
The data pointed to is NOT copied by the library: as a consequence, it must be
|
|
preserved by the calling application until the associated transfer finishes.
|
|
This behaviour can be changed (so libcurl does copy the data) by setting the
|
|
\fICURLOPT_COPYPOSTFIELDS(3)\fP option.
|
|
|
|
This POST is a normal application/x-www-form-urlencoded kind (and libcurl will
|
|
set that Content-Type by default when this option is used), which is commonly
|
|
used by HTML forms. Change Content-Type with \fICURLOPT_HTTPHEADER(3)\fP.
|
|
|
|
Using \fICURLOPT_POSTFIELDS(3)\fP implies \fICURLOPT_POST(3)\fP.
|
|
|
|
If you want to do a zero-byte POST, you need to set
|
|
\fICURLOPT_POSTFIELDSIZE(3)\fP explicitly to zero, as simply setting
|
|
\fICURLOPT_POSTFIELDS(3)\fP to NULL or "" just effectively disables the
|
|
sending of the specified string. libcurl will instead assume that you'll send
|
|
the POST data using the read callback!
|
|
|
|
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 as usual.
|
|
|
|
To make multipart/formdata posts (aka RFC2388-posts), check out the
|
|
\fICURLOPT_HTTPPOST(3)\fP option combined with \fIcurl_formadd(3)\fP.
