API for Authentication and Authorization

API for Authentication

Create User

POST http://staging-auth.elasticbeanstalk.com/auth/v1/user
{"email":"demouser@sagebase.org", "firstName":"demo", "lastName":"user", "displayName":"Demo User"}

Successful Response:

HTTP/1.1 201 Created

Missing password or user ID already exists:

HTTP/1.1 400 Bad Request

Update User

PUT http://staging-auth.elasticbeanstalk.com/auth/v1/user
sessionToken:<sessionToken>
{"email":"demouser@sagebase.org", "firstName":"demo", "lastName":"user", "displayName":"Demo User"}

 where <sessionToken> is that returned by "Initiate Session", below.  Note the authentication service manage the properties shown (principally the userId and password) while the repository services (below) manage other related user attributes.

Successful Response:

HTTP/1.1 204 No Content

Error Response, if the session token is missing or does not match userId:

HTTP/1.1 400 Bad Request
Content-Type: application/json
{"reason":"Not authorized."}

Send Change-Password Email

POST http://staging-auth.elasticbeanstalk.com/auth/v1/userPasswordEmail
{"email":"demouser"}

Successful Response:

HTTP/1.1 204 NO CONTENT

Initiate Session (Login)

Request:

POST http://staging-auth.elasticbeanstalk.com/auth/v1/session
{"email":"demouser@sagebase.org", "password":"demouser-pw"}

Successful Response:

HTTP/1.1 201 Created
Content-Type: application/json
{"displayName":"Demo User","sessionToken":"AYcOhWIm9NdOC6BdzzzisQ00"}

Error Response, if the user authentication details are incorrect:

HTTP/1.1 400 Bad Request
AuthenticationURL: http://staging-auth.elasticbeanstalk.com/auth/v1/session
Content-Type: application/json
{"reason":"Unable to authenticate."}

Session token is valid for a period of time, currently set to 24 hours.

Refresh Token (reset timer)

Request:

PUT http://staging-auth.elasticbeanstalk.com/auth/v1/session
{"sessionToken":"AYcOhWIm9NdOC6BdzzzisQ00"}

Successful Response:

HTTP/1.1 204 No Content

Error Response, if the session token is invalid:

HTTP/1.1 404 Not Found
{"reason":"Unable to validate session."}

Terminate Session (Logout)

 Note: Sessions initiated by multiple clients for the same user around the same time will receive identical "single sign on" tokens.  Since session termination is linked to the session token, terminating the session for one client via this command will have the side effect of terminating all sessions.  An alternative is for the client simply to delete its own copy of the token.

Request:

DELETE http://staging-auth.elasticbeanstalk.com/auth/v1/session
{"sessionToken":"AYcOhWIm9NdOC6BdzzzisQ00"}

Response:

HTTP/1.1 204 NO CONTENT

Sample commands, issued from cURL:

Create User:
curl -k -H "Content-Type:application/json" -H "Accept:application/json" -d "{\"email\":\"demouser@sagebase.org\", \"firstName\":\"demo\", \"lastName\":\"user\", \"displayName\":\"Demo User\"}" -X POST http://staging-auth.elasticbeanstalk.com/auth/v1/user

Update User:
curl -k -H "Content-Type:application/json" -H "Accept:application/json" -d "{\"email\":\"demouser@sagebase.org\", \"firstName\":\"NEWdemo\", \"lastName\":\"NEWuser\", \"displayName\":\"NEWDemo User\"}" -X PUT http://staging-auth.elasticbeanstalk.com/auth/v1/user

Send Change Password Email:
curl -k -H "Content-Type:application/json" -H "Accept:application/json" -d "{\"email\":\"demouser@sagebase.org\"}" -X POST http://staging-auth.elasticbeanstalk.com/auth/v1/userPasswordEmail

Login:
curl -k -H "Content-Type:application/json" -H "Accept:application/json" -d "{\"email\":\"demouser@sagebase.org\", \"password\":\"demouser-pw\"}" -X POST http://staging-auth.elasticbeanstalk.com/auth/v1/session

Refresh session token:

curl -k -H "Content-Type:application/json" -H "Accept:application/json" -d "{\"sessionToken\":\"QYNoamrOKK0dBhjZOFfbAg00\"}" -X PUT http://staging-auth.elasticbeanstalk.com/auth/v1/session

Logout:
curl -k -H "Content-Type:application/json" -H "Accept:application/json" -d "{\"sessionToken\":\"QYNoamrOKK0dBhjZOFfbAg00\"}" -X DELETE http://staging-auth.elasticbeanstalk.com/auth/v1/session

Access repository services anonymously:
curl -H Accept:application/json http://localhost:8080/repo/v1/dataset/test

Access repository services with session token (obtained by logging in):
curl -H Accept:application/json -H sessionToken:AprxPRzpmaPm7FXzV1ik0w00 http://localhost:8080/repo/v1/dataset/test

Authentication of Requests to Platform

Requests shall include a header named "sessionToken" whose value is that returned by the Initiate Session request, above.  (The session will timeout eventually, with a nominal duration of 24 hours.)

For requests that fail to be authenticated the response will include the headers:

WWW-Authenticate: authenticate Crowd

and a plain text body:  "The token provided was invalid or expired."

API for Authorization

Get the users who can be added to a resource's ACL

GET http://repositoryservice.sagebase.org/repo/v1/user

[
  {"name":"anonymous","id":"3","creationDate":1307402971000,"uri":null,"etag":null,"individual":true},
  {"name":"foo@sagebase.org","id":"4","creationDate":1307403226000,"uri":null,"etag":null,"individual":true}
]

Get the groups who can be added to a resource's ACL

GET http://repositoryservice.sagebase.org/repo/v1/userGroup

[
  {"name":"Identified Users","id":"1","creationDate":1307141423000,"uri":null,"etag":null,"individual":false},
  {"name":"Federation Group","id":"2","creationDate":1307141423000,"uri":null,"etag":null,"individual":false}
]

Note: The "id" fields returned from /user and /userGroup are used in the "userGroupId" fields in the ACLs shown below.

Get Access Control List for a Resource

Returns the ACL for the node responsible for the given node's permissions. Note: In the following example, 'resourceId' is the id of the node to which permissions are attached, either rid or one of rid's ancestors; 'resource_type' is the type of rid (project, dataset, layer, etc.); there is one 'resourceAccess' entry per UserGroup (aka 'principal') having access to the resource; 'userGroupId' is the id of the UserGroup object; 'accessType' is the list of types of access the given UserGroup has to the given resource.

GET http://repositoryservice.sagebase.org/repo/v1/{resource_type}/{rid}/acl

{"id":"1",
 "creationDate":1307141851484,
 "uri":null,
 "etag":"0",
 "createdBy":"admin",
 "resourceId":"1",
 "resourceAccess":[
	{"id":"1",
	 "userGroupId":"4",
	 "accessType":["READ","CHANGE_PERMISSIONS","DELETE","UPDATE","CREATE"]
	}
 ],
 "modifiedBy":"admin",
 "modifiedOn":1307141851483
}

Create Access Control List for a Resource

Note: This is only used when the resource 'rid' currently inherits its access control list from an ancestor. This request causes 'rid' to cease ACL inheritance and instead use the ACL passed in with the request.

POST http://repositoryservice.sagebase.org/repo/v1/{resource_type}/{rid}/acl
{
 "createdBy":"admin",
 "modifiedBy":"admin",
 "modifiedOn":1307141851483,
 "resourceId":{rid},
 "resourceAccess":[
	{"userGroupId":"4",
	 "accessType":["READ","CHANGE_PERMISSIONS","DELETE","UPDATE","CREATE"]
	}
 ]
}

Update Access Control List for a Resource

Note: This is only used when a "resourceId" already specifies its access control list (does not inherit from an ancestor).

PUT http://repositoryservice.sagebase.org/repo/v1/{resource_type}/{rid}/acl
{"id":"1",
 "creationDate":1307141851484,
 "uri":null,
 "etag":"0",
 "createdBy":"admin",
 "resourceId":{rid},
 "resourceAccess":[
	{"id":"1",
	 "userGroupId":"4",
	 "accessType":["READ","CHANGE_PERMISSIONS","DELETE","UPDATE","CREATE"]
	}
 ],
 "modifiedBy":"admin",
 "modifiedOn":1307141851483
}

Delete Access Control List for a Resource

This deletes the given object's ACL, restoring its dependence on its owner's permissions.

DELETE http://repositoryservice.sagebase.org/repo/v1/{resource_type}/{rid}/acl
