VERSION

This document describes version 0.24 of Perinci::Access::HTTP::Client (from Perl distribution Perinci-Access-HTTP-Client), released on 2017-07-03.

SYNOPSIS

 use Perinci::Access::HTTP::Client;
 my $pa = Perinci::Access::HTTP::Client->new;

 ## perform Riap requests

 # list all functions in package
 my $res = $pa->request(list => 'http://localhost:5000/api/',
                        {uri=>'/Some/Module/', type=>'function'});
 # -> [200, "OK", ['/Some/Module/mult2', '/Some/Module/mult2']]

 # call function
 $res = $pa->request(call => 'http://localhost:5000/api/',
                     {uri=>'/Some/Module/mult2', args=>{a=>2, b=>3}});
 # -> [200, "OK", 6]

 # get function metadata
 $res = $pa->request(meta => 'http://localhost:5000/api/',
                     {uri=>'/Foo/Bar/multn'});
 # -> [200, "OK", {v=>1.1, summary=>'Multiple many numbers', ...}]

 # pass HTTP credentials (via object attribute)
 my $pa = Perinci::Access::HTTP::Client->new(user => 'admin', password=>'123');
 my $res = $pa->request(call => '...', {...});
 # -> [200, "OK", 'result']

 # HTTP credentials can also be passed on a per-request basis
 my $pa = Perinci::Access::HTTP::Client->new();
 my $res = $pa->request(call => '...', {...}, {user=>'admin', password=>'123'});

 ## parse server URL
 $res = $pa->parse_url("https://cpanlists.org/api/"); # {proto=>"https", path=>"/App/cpanlists/Server/"}

DESCRIPTION

This class implements Riap::HTTP client.

ATTRIBUTES

• realm => STR

  For HTTP basic authentication. Defaults to "restricted area" (this is the default realm used by Plack::Middleware::Auth::Basic).

• user => STR

  For HTTP basic authentication. Default will be taken from environment PERINCI_HTTP_USER.

• password => STR

  For HTTP basic authentication. Default will be taken from environment PERINCI_HTTP_PASSWORD.

• ssl_cert_file => STR

  Path to SSL client certificate. Default will be taken from environment SSL_CERT_FILE.

• ssl_cert_file => STR

  Path to SSL CA certificate. Default will be taken from environment SSL_CA_FILE.

METHODS

PKG->new(%attrs) => OBJ

Instantiate object. Known attributes:

• retries => INT (default 2)

  Number of retries to do on network failure. Setting it to 0 will disable retries.

• retry_delay => INT (default 3)

  Number of seconds to wait between retries.

• log_level => INT (default 0 or from environment)

  Will be fed into Riap request key 'loglevel' (if >0). Note that some servers might forbid setting log level.

  If TRACE environment variable is true, default log_level will be set to 6. If DEBUG, 5. If VERBOSE, 4. If quiet, 1. Else 0.

• log_callback => CODE

  Pass log messages from the server to this subroutine. If not specified, log messages will be "rethrown" into Log::ger loggers (e.g. log_warn(), log_debug(), etc).

$pa->request($action => $server_url[, \%extra_keys[, \%client_opts]]) => $res

Send Riap request to $server_url. Note that $server_url is the HTTP URL of Riap server. You will need to specify code entity URI via uri key in %extra_keys.

%extra_keys is optional and contains additional Riap request keys (except action, which is taken from $action).

%client_opts is optional and contains additional information, like user (HTTP authentication user, overrides one in object attribute), password (HTTP authentication user, overrides one in object attribute).

$pa->parse_url($server_url[, \%client_opts]) => HASH

FAQ

How do I connect to a HTTP server that listens on a Unix socket?

This class can switch to using LWP::Protocol::http::SocketUnixAlt when it detects that the server is on a Unix socket, using this syntax (notice the single instead of double slash after http:):

 http:/path/to/unix.sock//uri

How do I connect to an HTTPS server without a "real" SSL certificate?

Since this module is using LWP, you can set environment variable PERL_LWP_SSL_VERIFY_HOSTNAME to 0. See LWP for more details.

ENVIRONMENT

PERINCI_HTTP_USER.

PERINCI_HTTP_PASSWORD.

SSL_CERT_FILE, SSL_CA_FILE.
