- Add new option CURLOPT_DEFAULT_PROTOCOL to allow specifying a default protocol for schemeless URLs. - Add new tool option --proto-default to expose CURLOPT_DEFAULT_PROTOCOL. In the case of schemeless URLs libcurl will behave in this way: When the option is used libcurl will use the supplied default. When the option is not used, libcurl will follow its usual plan of guessing from the hostname and falling back to 'http'.

.TH CURLOPT_DEFAULT_PROTOCOL 3 "18 Aug 2015" "libcurl 7.45.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_DEFAULT_PROTOCOL \- default protocol to use if the URL is missing a
|
|
scheme name
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DEFAULT_PROTOCOL, char
|
|
*protocol);
|
|
.SH DESCRIPTION
|
|
This option tells libcurl to use \fIprotocol\fP if the URL is missing a scheme
|
|
name.
|
|
|
|
Use one of these protocol (scheme) names:
|
|
|
|
dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps, pop3,
|
|
pop3s, rtsp, scp, sftp, smb, smbs, smtp, smtps, telnet, tftp
|
|
|
|
An unknown or unsupported protocol causes error
|
|
\fICURLE_UNSUPPORTED_PROTOCOL\fP when libcurl parses a schemeless URL. Parsing
|
|
happens when \fIcurl_easy_perform(3)\fP or \fIcurl_multi_perform(3)\fP is
|
|
called. The protocols supported by libcurl will vary depending on how it was
|
|
built. Use \fIcurl_version_info(3)\fP if you need a list of protocol names
|
|
supported by the build of libcurl that you are using.
|
|
|
|
This option does not change the default proxy protocol (http).
|
|
|
|
Without this option libcurl would make a guess based on the host, see
|
|
\fICURLOPT_URL(3)\fP for details.
|
|
.SH DEFAULT
|
|
NULL (make a guess based on the host)
|
|
.SH PROTOCOLS
|
|
All
|
|
.SH EXAMPLE
|
|
.nf
|
|
curl = curl_easy_init();
|
|
if(curl) {
|
|
/* set a URL without a scheme */
|
|
curl_easy_setopt(curl, CURLOPT_URL, "example.com");
|
|
|
|
/* set the default protocol (scheme) for schemeless URLs */
|
|
curl_easy_setopt(curl, CURLOPT_DEFAULT_PROTOCOL, "https");
|
|
|
|
/* Perform the request */
|
|
curl_easy_perform(curl);
