如何使用一次Fog调用在存储桶中创建S3对象？

Question

以下是在目录(S3存储桶)中创建文件(S3对象)的Fog演练:

connection = Fog::Storage.new({
  :provider                 => 'AWS',
  :aws_access_key_id        => YOUR_AWS_ACCESS_KEY_ID,
  :aws_secret_access_key    => YOUR_AWS_SECRET_ACCESS_KEY
})

directory = connection.directories.create(
  :key    => "fog-demo-#{Time.now.to_i}", # globally unique name
  :public => true
)

file = directory.files.create(
  :key    => 'resume.html',
  :body   => File.open("/path/to/my/resume.html"),
  :public => true
)

但它看起来好像这需要2个API调用:

1. connection.directories.create
2. directory.files.create

如果我已经创建了目录(S3存储桶),如何创建只有一个Fog调用的文件(S3对象)？

Answer 1

如果您知道该目录存在,您可以这样做

dir = connection.directories.new(:key => 'foo')# no request made
dir.files.create(...)
