我正在使用 Google Drive Ruby 客户端并尝试将一些工作表文档导出为 CSV 格式。我可以很好地获取我的文件，但是当我尝试访问exportLinks它时，它似乎并不存在于我的文件中，即使它确实在 Google 网站上的 API Explorer 中返回了它。这是我试图获得exportLink当前的方式：

client = Google::APIClient.new(:application_name => APPLICATION_NAME)
client.authorization = authorize
drive_api = client.discovered_api('drive', 'v2')

result = client.execute!(
               :api_method => drive_api.files.get,
               :parameters => {:fileId => "1MBP9Q9Q-9ZgLoYnY8ExS-EcxHLESI_vcK4J91ngp6-Q"})
file = result.data
puts("Fetched #{file["title"]}")
puts("Getting downloadURL")
exportLinks = file['exportLinks']['text/csv']

我不断收到一条错误消息，提示“nil:NilClass (NoMethodError) 的未定义方法 '[]'。” 因此，由于某种原因，我没有从 . 得到任何返回exportLinks。有人知道这是为什么吗？方法是否已更改，但尚未在 API Explorer 上更新？我是否犯了其他愚蠢的错误？我是否在某处遗漏了逗号？任何帮助是非常感谢！

如果您需要更多代码，请告诉我。

编辑 2：我注销了收到的回复......而且它确实不包括 exportLinks。

这是我的应用程序看到的（相关部分）响应：

"parents": [
{
 "kind": "drive#parentReference",

 "selfLink": "https://www.googleapis.com/drive/v2/files/1MBP9Q9Q-9ZgLoYnY8ExS-EcxHLESI_vcK4J91ngp6-Q/parents/0AJj4OUAR-EvNUk9PVA",

响应 API Explorer 显示我应该得到：

不确定这是否有帮助，但在我尝试使用 google drive api 的共享 google 工作表的共享设置 UI 中，如果我选中Disable options to download, print, and copy for commenters and viewers复选框，那么来自 google 的 json 响应将不包括 exportLinks 条目
