Rails：在Bluemix Object Storage上使用霧（回形針）v2

我試圖使用Bluemix Object Storage來存儲一些用戶內容（圖像）。它運行Openstack Swift。Rails：在Bluemix Object Storage上使用霧（回形針）v2

根據bluemix guide，它支持Keystone V2身份驗證unbound context或Keystone v3綁定上下文中。由於我的主應用程序不在同一個Bluemix環境中，我更喜歡使用unbound，但也可以通過虛擬應用程序使用綁定。

根據霧化寶石和霧源代碼的一些發行註記，兩種auth方法都受支持。我使用霧1.31.0。

使用未綁定的方法，在創建Bluemix服務後，我獲得了以下憑據。由於隱私原因，所有值都會稍作更改。

{ 
    "credentials": { 
    "auth_url": "https://identity.open.softlayer.com", 
    "project": "object_storage_af31119c", 
    "projectId": "82e592b46bb84232370f9657fec2b576", 
    "region": "dallas", 
    "userId": "02faa40ff3f342faaafdty1a75bd901a", 
    "username": "user_28uigjab0a2ef799eb5280c786a2ff503c978aaf", 
    "password": "V3i~]oYU8/UMNvVm", 
    "domainId": "3f160e53e6114a748a34724005a458ea", 
    "domainName": "779543" 
    } 
}

霧OpenStack的文檔包含this配置示例：

service = Fog::Storage.new({ 
    :provider   => 'OpenStack', # OpenStack Fog provider 
    :openstack_username => USERNAME,  # Your OpenStack Username 
    :openstack_api_key => PASSWORD,  # Your OpenStack Password 
    :openstack_auth_url => 'http://YOUR_OPENSTACK_ENDPOINT:PORT/v2.0/tokens' 
})

我充滿了我的憑據，並使用https://identity.open.softlayer.com/v2.0/tokens作爲auth_url。這是錯誤我得到：

很顯然，我的憑據不能正確發送。任何提示？

您的Openstack用戶屬於'779543'域。身份（Keystone）v3 API支持域。我找不到有關如何使用Keystone v3和Fog的好例子。

根據文檔Bluemix OpenStack Swift

開棧身份（梯形失真校正）V2

的V2令牌請求是POST請求 https://identity.open.softlayer.com/v2.0/tokens如圖中以下curl命令：

curl -i \ 
-H "Content-Type: application/json" \ 
-d ' 
{ 
    "auth": { 
     "tenantId": "0f47b41b06d047f9aae3b33f1db061ed", 
     "passwordCredentials": { 
     "userId": "ad78b2a3f843466988afd077731c61fc", 
     "password": "K/jyIi2jR=1?D.TP " 
    } 
} 
}' \ 
https://identity.open.softlayer.com/v2.0/tokens ; echo

注意：此請求方法未在OpenStack Identity v2網站上記錄。 您不能使用tenantName和用戶名。

霧:: OpenStack的（和許多其他庫）使用的用戶名代替的用戶id

您應該使用OpenStack的身份（梯形）V3這樣：

storage = Fog::OpenStack.new({ 
    :provider     => 'OpenStack', 
    :openstack_auth_url  => credentials['auth_url'], 
    :openstack_api_key  => credentials['password'], 
    :openstack_project_id  => credentials['projectId'],   
    :openstack_username  => credentials['username'], 
    :openstack_domain_name => credentials['domainName'],#required if you use :openstack_username (otherwise set :openstack_userid) 
    :openstack_region   => credentials['region'] 
})
