Question

我正在使用Google云端硬盘客户端，并尝试将某些工作表文档导出为CSV格式。我可以正常使用我的文件，但在尝试访问exportLinks时，它似乎不存在于我的文件中，即使它确实在Google网站的API资源管理器中返回它。以下是我尝试获取exportLink的方法：

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']

我不断收到错误说＆＃34;未定义的方法＆＃39; []＆＃39; for nil：NilClass（NoMethodError）。＆＃39;所以由于某种原因，我没有收到exportLinks返回的任何内容。有谁知道这是为什么？方法是否已更改，但尚未在API Explorer上更新？我还犯了其他一些愚蠢的错误吗？我在某个地方错过了一个逗号吗？非常感谢任何帮助！

如果您需要更多代码，请与我们联系。

编辑2：我注销了我得到的回复......而且确实没有包含exportLinks。

以下是我的应用程序看到的（相关部分）响应：

响应API Explorer告诉我应该得到：

不确定是否有这个帮助，但是在我尝试使用google驱动器api的共享google工作表的共享设置界面中，如果我选中Disable options to download, print, and copy for commenters and viewers复选框，则谷歌的json响应将不会包括exportLinks条目
