OpenStack Swift + Keystone：无法确定租期

Question

I'm trying to access Swift with curl using Keystone-based authentication (following the Keystone API docs here ).

Chapter 1: Fetching the token:

curl -d '{"auth": {"passwordCredentials": {
                     "username": "USERNAME", "password": "PASSWORD"}}}' \
     -H "Content-Type: application/json" \
     http://identity:35357/v2.0/tokens

Response:

{
  "access": {
    "token": {
      "expires": "2014-02-27T11:35:11Z", 
      "id": "TOKENID"
    }, 
    "serviceCatalog": [], 
    "user": {
      "username": "USERNAME", 
      "roles_links": [], 
      "id": "USERID", 
      "roles": [], 
      "name": "NAME"
    }
   }
}

Note that, contrary to what's said in the API docs , the tenant info is missing from the response.

Chapter 2: Authentication

curl -H "X-Auth-Token: TOKENID" http://swift/v1/AUTH_TENANTID/bucket

Response: 401 Unauthorized

Chapter 3: Troubleshooting

After looking inside the Keystone auth_token middleware, I found that it fails when trying to fetch the tenant from the token data:

def get_tenant_info():
    """Returns a (tenant_id, tenant_name) tuple from context."""
    def essex():
        """Essex puts the tenant ID and name on the token."""
        return (token['tenant']['id'], token['tenant']['name'])

    def pre_diablo():
        """Pre-diablo, Keystone only provided tenantId."""
         return (token['tenantId'], token['tenantId'])

    def default_tenant():
        """Pre-grizzly, assume the user's default tenant."""
        return (user['tenantId'], user['tenantName'])

    for method in [essex, pre_diablo, default_tenant]:
        try:
            return method()
        except KeyError:
             pass

    raise InvalidUserToken('Unable to determine tenancy.')

Since there is no tenant info in the token data, it always fails. What might I be doing wrong?

Answer 1

This answer addresses your initial authentication question, but not the rest of the question...

Your initial request:

curl -d '{"auth": {"passwordCredentials": {
                     "username": "USERNAME", "password": "PASSWORD"}}}' \
     -H "Content-Type: application/json" \
     http://identity:35357/v2.0/tokens

Needs to provide either a tenantName or tenantId attribute. With either of these supplied, your reply should include both the tenant information and a service catalog, for looking up other service endpoints.

So:

curl -d '{"auth": {"tenantName": "mytenant", "passwordCredentials": {
                         "username": "USERNAME", "password": "PASSWORD"}}}' \
         -H "Content-Type: application/json" \
         http://identity:35357/v2.0/tokens

Which should get you something like this:
