NAME¶
Net::Duo - API for Duo multifactor authentication service
SYNOPSIS¶
my $duo = Net::Duo->new({ key_file => '/path/to/keys.json' });
my $reply = $duo->call_json('GET', '/auth/v2/check');
REQUIREMENTS¶
Perl 5.14 or later and the modules HTTP::Request and HTTP::Response (part of
HTTP::Message), JSON, LWP (also known as libwww-perl), Perl6::Slurp, and
URI::Escape (part of URI), all of which are available from CPAN.
DESCRIPTION¶
Net::Duo provides an object-oriented Perl interface for generic calls to one of
the the Duo Security REST APIs. This module is intended primarily for use as a
base class for more specialized Perl modules implementing the specific Duo
APIs, but it can also be used directly to make generic API calls.
On failure, all methods throw a Net::Duo::Exception object. This can be
interpolated into a string for a simple error message, or inspected with
method calls for more details. This is also true of all methods in all objects
in the Net::Duo namespace.
CLASS METHODS¶
- new(ARGS)
- Create a new Net::Duo object. This should be used for all subsequent API
calls. ARGS should be a hash reference with one or more of the following
keys:
- api_hostname
- The API hostname returned by Duo when the API integration was created.
This key is required if "key_file" is not set.
- integration_key
- The integration key returned by Duo when the API integration was created.
This is effectively the public "username" for this integration.
This key is required if "key_file" is not set.
- key_file
- The path to a file in JSON format that contains the key and hostname data
for a Duo integration. This file should contain one JSON object with keys
"integration_key", "secret_key", and
"api_hostname". These are the three data values that are
returned when one creates a new Duo API integration.
Be aware that the "secret_key" value in this file is
security-sensitive information equivalent to a password. Anyone in
possession of that key has complete control of all data and actions to
which the integration has access.
Either this key or all of "integration_key",
"secret_key", and "api_hostname" must be provided. If
both this key and some of those keys are provided, their values will
override the values retrieved from the "key_file" file.
- secret_key
- The secret key returned by Duo when the API integration was created. This
is security-sensitive information equivalent to a password. Anyone in
possession of that key has complete control of all data and actions to
which the integration has access. Do not hard-code this into programs;
instead, read it from a file with appropriate permissions or retrieve it
via some other secure mechanism.
This key is required if "key_file" is not set.
- user_agent
- The user agent to use for all requests. This should be a Perl object that
supports the same API as LWP::UserAgent.
Normally, the caller will not provide this key, in which case Net::Duo will
create an LWP::UserAgent object internally to use to make Duo API calls.
This argument is provided primarily so that the user agent can be
overridden for unit testing.
INSTANCE METHODS¶
- call(METHOD, PATH[, ARGS])
- Make a generic Duo API call, with no assumptions about the response.
This is a low-level escape hatch to make any Duo API call that this module
does not know about, regardless of what format in which it returns its
results. The caller will have to provide all of the details (HTTP method,
URL path, and all arguments as a reference to a hash of key/value pairs).
The URL path must start with a slash.
The return value is the resulting HTTP::Response object from the web API
call. No error checking will be performed. The caller is responsible for
examining the HTTP::Response object for any problems, including internal
or HTTP errors.
Most Duo API calls return structured JSON and follow a standard pattern for
indicating errors. For those calls, use call_json() instead of this
method. call() is needed only for the small handful of API calls
that do not return JSON in that format, such as the Auth API
"/logo" endpoint.
- call_json(METHOD, PATH[, ARGS])
- Make a generic Duo API call that returns a JSON response.
This is the escape hatch to use to make any Duo API call that this module
does not know about. The caller will have to provide all of the details
(HTTP method, URL path, and all arguments as a reference to a hash of
key/value pairs). The URL path must start with a slash.
The return value will be only the value of the response key from the
returned JSON. This method still handles checking the "stat"
value from Duo and throwing a Net::Duo::Exception object on call failure.
This method cannot be used with the small handful of API calls that do not
return JSON, such as the Auth API "/logo" endpoint.
