.TH CURLOPT_PROTOCOLS_STR 3 "11 Jun 2022" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_PROTOCOLS_STR \- allowed protocols
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROTOCOLS_STR, char *spec);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a string that holds a comma-separated list of case
|
|
insensitive protocol names (URL schemes) to allow in the transfer. This
|
|
option allows applications to use libcurl built to support a wide range of
|
|
protocols but still limit specific transfers to only be allowed to use a
|
|
subset of them. By default, libcurl accepts all protocols it was built with
|
|
support for. See also \fICURLOPT_REDIR_PROTOCOLS_STR(3)\fP.
|
|
|
|
If trying to set a non-existing protocol or if no matching protocol at all is
|
|
set, it returns error.
|
|
|
|
These are the available protocols:
|
|
|
|
DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS,
|
|
MQTT, POP3, POP3S, RTMP, RTMPE, RTMPS, RTMPT, RTMPTE, RTMPTS, RTSP, SCP, SFTP,
|
|
SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS, WSS
|
|
|
|
You can set "ALL" as a short-cut to enable all protocols. Note that by setting
|
|
all, you may enable protocols that were not supported the day you write this
|
|
but are introduced in a future libcurl version.
|
|
|
|
\fIcurl_version_info(3)\fP can be used to get a list of all supported
|
|
protocols in the current libcurl. \fICURLINFO_SCHEME(3)\fP is the recommended
|
|
way to figure out the protocol used in a previous transfer.
|
|
.SH DEFAULT
|
|
All protocols built-in

|
.SH EXAMPLE
|
|

|
|
curl = curl_easy_init();
|

if(curl) {
|
|
/* pass in the URL from an external source */
|
|
curl_easy_setopt(curl, CURLOPT_URL, argv[1]);
|
|
|
|
/* only allow HTTP, TFTP and SFTP */
|
|
curl_easy_setopt(curl, CURLOPT_PROTOCOLS_STR, "http,tftp,sftp");
|
|
|
|
/* Perform the request */
|
|
curl_easy_perform(curl);

|
}

.SH RETURN VALUE
|
|
Returns CURLE_UNKNOWN_OPTION if the option is not implemented,
|
|
CURLE_UNSUPPORTED_PROTOCOL if a listed protocol is not supported or disabled,
|
|
CURLE_BAD_FUNCTION_ARGUMENT if no protocol is listed else CURLE_OK.
