Net::OAuth2::Profile(3) OAuth2 access profiles

INHERITANCE

 Net::OAuth2::Profile is extended by
   Net::OAuth2::Profile::Password
   Net::OAuth2::Profile::WebServer

SYNOPSIS


See Net::OAuth2::Profile::WebServer
and Net::OAuth2::Profile::Password

DESCRIPTION

Base class for OAuth `profiles'. Currently implemented:
  • Net::OAuth2::Profile::WebServer
  • Net::OAuth2::Profile::Password

You may want to use the OAuth2 documentation at Google <https://developers.google.com/accounts/docs/OAuth2WebServer> to understand the process and the parameters.

METHODS

Constructors

Net::OAuth2::Profile->new(%options)
Next to the %options listed below, it is possible to provide settings for each of the <${commands}> "access_token", "protected_resource", "authorize", and "refresh_token". For each command, you can set
  • ${command}_url => URI|STRING

    The absolute uri which needs to be used to be addressed to execute the $command. May be specified as URI object or STRING.

  • ${command}_path => PATH

    As previous, but relative to the "site" option value.

  • ${command}_method => 'GET'|'POST'

    Which method to use for the call (by default POST).

  • ${command}_param => []

    Additional parameters for the command. 

 -Option           --Default
  client_id          <required>
  client_secret      <required>
  grant_type         <required>
  scope              undef
  secrets_in_params  <true>
  site               undef
  state              undef
  token_scheme       'auth-header:Bearer'
  user_agent         <created internally>
client_id => STRING
client_secret => STRING
grant_type => STRING
scope => STRING
secrets_in_params => BOOLEAN
The client secrets are passed both via an Authentication header, as via query parameters in the URI. The former is required to be accepted by rfc6749, the latter is optional. However: many servers use the query parameters only.

QQ Catalyst, on the other hand, does refuse requests with these parameters in the query. So, with this flag explicitly set to false, only the Auth header gets included.

site => URI
state => STRING
token_scheme => SCHEME
See add_token() for the supported SCHEMEs. Scheme "auth-header" is probably the only sane default, because that works with any kind of http requests, where the other options have limited or possible disturbing application.

Before [0.53], the default was 'auth-header:OAuth'.

Specify the method to submit authenticated requests to the service. By default, add the access token as a header, such as: ``Authorization: Bearer TOKEN''. Some services require that the header will be different, i.e. ``Authorization: OAuth TOKEN'', for which case specify token_scheme 'auth-header:Oauth'.

To add the access token as a uri-parameter: 'uri-query:oauth_token' (in this case, the parameter name will be oauth_token) Merge the access token inside a form body via 'form-body:oauth_token'

user_agent => LWP::UserAgent object

Accessors

$obj->bearer_token_scheme()
$obj->grant_type()
$obj->id()
$obj->scope()
$obj->secret()
$obj->site()
$obj->state()
$obj->user_agent()

Actions

HTTP
$obj->request( $request, [$more] )
Send the $request (a HTTP::Request object) to the server, calling LWP::UserAgent method "request()". This method will NOT add security token information to the message.
$obj->request_auth( $token, <$request | <$method, $uri, [$header, $content]>> )
Send an authorized request: the $token information gets included in the request object. Returns the answer (HTTP::Response).

example: 

  my $auth  = Net::OAuth2::Profile::WebServer->new(...);
  my $token = $auth->get_access_token($code, ...);
  # possible...
  my $resp  = $auth->request_auth($token, GET => $uri, $header, $content);
  my $resp  = $auth->request_auth($token, $request);
  # nicer (?)
  my $resp  = $token->get($uri, $header, $content);
  my $resp  = $token->request($request);

Helpers

$obj->add_token($request, $token, $scheme)
Merge information from the $token into the $request following the the bearer token $scheme. Supported schemes:
  • auth-header or auth-header:REALM

    Adds an "Authorization" header to requests. The default REALM is "OAuth", but "Bearer" and "OAuth2" may work as well.

  • uri-query or uri-query:FIELD

    Adds the token to the query parameter list. The default FIELD name used is "oauth_token".

  • form-body or form-body:FIELD

    Adds the token to the www-form-urlencoded body of the request. The default FIELD name used is "oauth_token".

$obj->build_request($method, $uri, $params)
Returns a HTTP::Request object. $params is an HASH or an ARRAY-of-PAIRS of query parameters.
$obj->params_from_response($response, $reason)
Decode information from the $response by the server (an HTTP::Response object). The $reason for this answer is used in error messages.
$obj->site_url( <$uri|$path>, $params )
Construct a URL to address the site. When a full $uri is passed, it appends the $params as query parameters. When a $path is provided, it is relative to new(site).
