NAME
Plack::Auth::SSO::ORCID - implementation of Plack::Auth::SSO for ORCID
SYNOPSIS
#in your app.psgi
builder {
#Register THIS URI in ORCID as a new redirect_uri

client_id => "APP-1",
client_secret => "mypassword",
sandbox => 1,
uri_base => "http://localhost:5000",
authorization_path => "/auth/orcid/callback",
error_path => "/auth/error"
)->to_app;
#DO NOT register this uri as new redirect_uri in ORCID
mount "/auth/orcid/callback" => sub {
my $env = shift;

my $auth_sso = $session->get("auth_sso");
#not authenticated yet

};DESCRIPTION
This is an implementation of Plack::Auth::SSO to authenticate against a ORCID (OAuth) server.
It inherits all configuration options from its parent.
Remember that this module only performs these steps:
* redirect to ORCID authorize url
* exchange 1: exchange authorization code for access token ( orcid and name known )
This delivers a hash containing orcid, name, access_token and a refresh_token.* exchange 2: exchange access_token for person information
This delivers a hash containing detailed information.So we actually retrieved two hashes.
Those steps provide the following information:
* uid: derived from "orcid" from the first hash
* info.name: derived from "name" from the first hash
* other keys in "info" are extracted from the second hash
* info.first_name: string
* info.last_name: string
* info.other_names: array of strings
* info.email: first primary and verified email
* info.description: string. Retrieved from "biography".
* info.location: country code
* info.url: array of objects
* info.external_identifiers: array of objects* extra: both hashes from the first and second call to ORCID are merged. For obvious reasons "orcid" is not present, and neither is "name" because it has a conflicting format between the two responses.
extra.access_token contains a code that conforms to the scope requested (see below).
If you want to request additional information from ORCID
CONFIG
Register the uri of this application in ORCID as a new redirect_uri.
DO NOT register the authorization_path in ORCID as the redirect_uri!
- client_id
-
client_id for your application (see developer credentials from ORCID)
- client_secret
-
client_secret for your application (see developer credentials from ORCID)
- sandbox
-
0|1. Defaults to 0. When set to 1, this api makes use of http://sandbox.orcid.org instead of http://orcid.org.
- public
-
0|1. Defaults to 1. 0 means you're using the member API.
- scope
-
Requested scope. When not set, the parameter "public" will decide the value:
* public 1 : scope is "/authenticate"
* public 0 : scope is "/read-limited"
Please consult the ORCID to make sure that the parameters "public" and "scope" do not clash. (e.g. public is 1 and scope is "/read-limited")
ERRORS
Known ORCID errors are stored in the session key auth_sso_error ( Plack::Auth::SSO ).
"error" becomes "type"
"error_description" becomes "content"
Example:
{
package => "Plack::Auth::SSO::ORCID",
package_id => "Plack::Auth::SSO::ORCID",
type => "invalid_grant",
content => "Reused authorization code: abcdefg"
}https://members.orcid.org/api/resources/error-codes
when it receives an non json response from ORCID, the type is "unknown", and content is set to the full return value.
