.TH CURLOPT_CUSTOMREQUEST 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_CUSTOMREQUEST \- custom string for request
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CUSTOMREQUEST, char *request);
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a zero terminated string as parameter.
|
|
|
|
When you change the request method by setting \fICURLOPT_CUSTOMREQUEST(3)\fP
|
|
to something, you don't actually change how libcurl behaves or acts in regards
|
|
to the particular request method, it will only change the actual string sent
|
|
in the request.
|
|
|
|
Restore to the internal default by setting this to NULL.
|
|
|
|
This option can be used to specify the request:
|
|
.IP HTTP
|
|
Instead of GET or HEAD when performing HTTP based requests. This is
|
|
particularly useful, for example, for performing an HTTP DELETE request.
|
|
|
|
For example:
|
|
|
|
When you tell libcurl to do a HEAD request, but then specify a GET though a
|
|
custom request libcurl will still act as if it sent a HEAD. To switch to a
|
|
proper HEAD use \fICURLOPT_NOBODY(3)\fP, to switch to a proper POST use
|
|
\fICURLOPT_POST(3)\fP or \fICURLOPT_POSTFIELDS(3)\fP and to switch to a proper
|
|
GET use \fICURLOPT_HTTPGET(3)\fP.
|
|
|
|
Many people have wrongly used this option to replace the entire request with
|
|
their own, including multiple headers and POST contents. While that might work
|
|
in many cases, it will cause libcurl to send invalid requests and it could
|
|
possibly confuse the remote server badly. Use \fICURLOPT_POST(3)\fP and
|
|
\fICURLOPT_POSTFIELDS(3)\fP to set POST data. Use \fICURLOPT_HTTPHEADER(3)\fP
|
|
to replace or extend the set of headers sent by libcurl. Use
|
|
\fICURLOPT_HTTP_VERSION(3)\fP to change HTTP version.
|
|
|
|
.IP FTP
|
|
Instead of LIST and NLST when performing FTP directory listings.
|
|
.IP IMAP
|
|
Instead of LIST when issuing IMAP based requests.
|
|
.IP POP3
|
|
Instead of LIST and RETR when issuing POP3 based requests.
|
|
|
|
For example:
|
|
|
|
When you tell libcurl to use a custom request it will behave like a LIST or
|
|
RETR command was sent where it expects data to be returned by the server. As
|
|
such \fICURLOPT_NOBODY(3)\fP should be used when specifying commands such as
|
|
DELE and NOOP for example.
|
|
.IP SMTP
|
|
Instead of a HELP or VRFY when issuing SMTP based requests.
|
|
|
|
For example:
|
|
|
|
Normally a multiline response is returned which can be used, in conjunction
|
|
with \fICURLOPT_MAIL_RCPT(3)\fP, to specify an EXPN request. If the
|
|
\fICURLOPT_NOBODY(3)\fP option is specified then the request can be used to
|
|
issue NOOP and RSET commands.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|

NULL
