GetObject 用于获取某个 Object

Examples

iex> Aliyun.Oss.Object.get_object("some-bucket", "some-object")
{:ok, %Aliyun.Oss.Client.Response{
    data: <<208, 207, 17, 224, 161, 177, 26, 225, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
      0, 0, 0, 62, 0, 3, 0, 254, 255, 9, 0, 6, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 18,
      0, 0, 0, ...>>,
    headers: [
      {"Date", "Wed, 05 Dec 2018 02:34:57 GMT"},
      ...
    ]
  }
}

亦可用于获取某个 Object 指定 SubResource(GetObjectXXX)。

Examples

iex> Aliyun.Oss.Object.get_object("some-bucket", "some-object", %{}, %{"acl" => nil})
{:ok, %Aliyun.Oss.Client.Response{
  data: %{
    "AccessControlPolicy" => %{
      "AccessControlList" => %{"Grant" => "default"},
      "Owner" => %{
        "DisplayName" => "1111111111111111",
        "ID" => "1111111111111111"
      }
    }
  },
  headers: [
    {"Date", "Wed, 05 Dec 2018 02:34:57 GMT"}
  ]
}

GetObjectACL 用来获取某个Bucket下的某个Object的访问权限。

Examples

iex> Aliyun.Oss.Object.get_object_acl("some-bucket", "some-object")
{:ok, %Aliyun.Oss.Client.Response{
  data: %{
    "AccessControlPolicy" => %{
      "AccessControlList" => %{"Grant" => "default"},
      "Owner" => %{
        "DisplayName" => "1111111111111111",
        "ID" => "1111111111111111"
      }
    }
  },
  headers: [
    {"Date", "Wed, 05 Dec 2018 02:34:57 GMT"}
  ]
}

HeadObject只返回某个Object的meta信息，不返回文件内容。

Examples

iex> Aliyun.Oss.Object.head_object("some-bucket", "some-object")
{:ok,
%Aliyun.Oss.Client.Response{
  data: "",
  headers: [
    {"Server", "AliyunOSS"},
    {"Date", "Wed, 05 Dec 2018 05:50:02 GMT"},
    {"Content-Type", "application/octet-stream"},
    {"Content-Length", "0"},
    {"Connection", "keep-alive"},
    {"x-oss-request-id", "5C0000000000000000000000"},
    {"Accept-Ranges", "bytes"},
    {"ETag", ""D4100000000000000000000000000000""},
    {"Last-Modified", "Mon, 15 Oct 2018 01:38:47 GMT"},
    {"x-oss-object-type", "Normal"},
    {"x-oss-hash-crc64ecma", "0"},
    {"x-oss-storage-class", "IA"},
    {"Content-MD5", "1B2M2Y8AsgTpgAmY7PhCfg=="},
    {"x-oss-server-time", "19"}
  ]
}}
iex> Aliyun.Oss.Object.head_object("some-bucket", "unknown-object")
{:error, %Aliyun.Oss.Client.Error{status_code: 404, body: "", parsed_details: nil}}

生成包含签名的 URL

Examples

iex> expires = Timex.now() |> Timex.shift(days: 1) |> Timex.to_unix()
iex> Aliyun.Oss.Object.object_url("some-bucket", "some-object", expires)
"http://oss-example.oss-cn-hangzhou.aliyuncs.com/oss-api.pdf?OSSAccessKeyId=nz2pc56s936**9l&Expires=1141889120&Signature=vjbyPxybdZaNmGa%2ByT272YEAiv4%3D"
