Question

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

第1章：获取令牌：

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

响应：

{
  "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中的说法相反，回复中缺少租户信息。

第2章：身份验证

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

回复：401 Unauthorized

第3章：疑难解答

在查看Keystone auth_token中间件后，我发现尝试从令牌数据中获取租户时失败了：

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.')

由于令牌数据中没有租户信息，因此始终失败。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。使用其中任何一个，您的回复应包括租户信息和服务目录，以便查找其他服务端点。

所以：

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

哪个可以得到这样的东西：

{
  "access": {
    "metadata": {
      "roles": [
        "9fe2ff9ee4384b1894a90878d3e92bab",

    },
    "user": {

        {
          "name": "_member_"
        },
        {
          "name": "admin"
        }
      ],
      "id": "436d522125584cf3a21ddcf628d59e2e",
      "roles_links": [],
      "username": "lars"
    },
    "serviceCatalog": [
      {
        "name": "nova",
        "type": "compute",
        "endpoints_links": [],
        "endpoints": [
          {
            "publicURL": "http://192.168.200.1:8774/v2/28a490a259974817b88ce490a74df8d2",

          }
        ]
      },
      .
      .
      .
    ],
    "token": {
      "tenant": {
        "name": "users/lars",
        "id": "28a490a259974817b88ce490a74df8d2",

      "issued_at": "2014-02-20T20:07:36.189044"
    }
  }
}
