python - OpenStack Swift + Keystone : Unable to determine tenancy

Question

我正在尝试使用基于 Keystone 的身份验证通过curl 访问 Swift(遵循 Keystone API docs here )。

第 1 章:获取 token :

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

回应:

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

请注意，与 API docs 中所述相反，响应中缺少租户信息。

第 2 章:身份验证

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

响应:401 未经授权

第 3 章:故障排除

查看 Keystone auth_token 中间件后，我发现尝试从 token 数据中获取租户时失败:

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.')

由于 token 数据中没有租户信息，因此总是失败。我可能做错了什么？

Answer 1

此答案解决了您的初始身份验证问题，但不是问题的其余部分...

您的初始请求:

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

需要提供 tenantName 或 tenantId 属性。提供其中任何一个后，您的回复应包含租户信息和服务目录，用于查找其他服务端点。

所以:

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

这应该给你这样的东西:
