OSSL_HTTP_PARSE_URL(3ossl) OpenSSL OSSL_HTTP_PARSE_URL(3ossl)
NAME
OSSL_HTTP_adapt_proxy, OSSL_parse_url, OSSL_HTTP_parse_url,
OCSP_parse_url - http utility functions
SYNOPSIS
#include <openssl/http.h>
const char *OSSL_HTTP_adapt_proxy(const char *proxy, const char *no_proxy,
const char *server, int use_ssl);
int OSSL_parse_url(const char *url, char **pscheme, char **puser, char **phost,
char **pport, int *pport_num,
char **ppath, char **pquery, char **pfrag);
int OSSL_HTTP_parse_url(const char *url,
int *pssl, char **puser, char **phost,
char **pport, int *pport_num,
char **ppath, char **pquery, char **pfrag);
The following functions have been deprecated since OpenSSL 3.0, and can
be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
version value, see openssl_user_macros(7):
int OCSP_parse_url(const char *url, char **phost, char **pport, char **ppath,
int *pssl);
DESCRIPTION
OSSL_HTTP_adapt_proxy() takes an optional proxy hostname proxy and
returns it transformed according to the optional no_proxy parameter,
server, use_ssl, and the applicable environment variable, as follows.
If proxy is NULL, take any default value from the "http_proxy"
environment variable, or from "https_proxy" if use_ssl is nonzero. If
this still does not yield a proxy hostname, take any further default
value from the "HTTP_PROXY" environment variable, or from "HTTPS_PROXY"
if use_ssl is nonzero. If no_proxy is NULL, take any default exclusion
value from the "no_proxy" environment variable, or else from
"NO_PROXY". Return the determined proxy host unless the exclusion
value, which is a list of proxy hosts separated by "," and/or
whitespace, contains server. Otherwise return NULL. When server is a
string delimited by "[" and "]", which are used for IPv6 addresses, the
enclosing "[" and "]" are stripped prior to comparison.
OSSL_parse_url() parses its input string url as a URL of the form
"[scheme://][userinfo@]host[:port][/path][?query][#fragment]" and
splits it up into scheme, userinfo, host, port, path, query, and
fragment components. The host (or server) component may be a DNS name
or an IP address where IPv6 addresses must be enclosed in square
brackets "[" and "]". The port component is optional and defaults to
0. If given, it must be in decimal form. If the pport_num argument is
not NULL the integer value of the port number is assigned to *pport_num
on success. The path component is also optional and defaults to "/".
Each non-NULL result pointer argument pscheme, puser, phost, pport,
ppath, pquery, and pfrag, is assigned the respective url component.
Any IPv6 address in *phost is enclosed in "[" and "]". On success,
they are guaranteed to contain non-NULL string pointers, else NULL. It
is the responsibility of the caller to free them using OPENSSL_free(3).
If pquery is NULL, any given query component is handled as part of the
path. A string returned via *ppath is guaranteed to begin with a "/"
character. For absent scheme, userinfo, port, query, and fragment
components an empty string is provided.
OSSL_HTTP_parse_url(3) is a special form of OSSL_parse_url() where the
scheme, if given, must be "http" or "https". If pssl is not NULL,
*pssl is assigned 1 in case parsing was successful and the scheme is
"https", else 0. The port component is optional and defaults to 443 if
the scheme is "https", else 80. Note that relative paths must be given
with a leading "/", otherwise the first path element is interpreted as
the host.
Calling the deprecated function OCSP_parse_url(url, host, port, path,
ssl) is equivalent to OSSL_HTTP_parse_url(url, ssl, NULL, host, port,
NULL, path, NULL, NULL).
RETURN VALUES
OSSL_HTTP_adapt_proxy() returns NULL if no proxy is to be used,
otherwise a constant proxy hostname string, which is either the proxy
name handed in or an environment variable value.
OSSL_HTTP_parse_url(3), and OCSP_parse_url() return 1
on success, 0 on error.
