Google表格Java API v4 BatchUpdate

标签: java oauth-2.0 google-oauth google-sheets-api

以下代码实际上只是Google表格Java API v4快速入门代码示例,但是我从另一篇文章中复制了BatchUpdate的代码以进行尝试;运行代码会产生一个异常,该异常引用包含文本的JSON对象:

  

"消息" :"请求的身份验证范围不足。",   "理由" :"禁止"

因为代码访问电子表格获取数据没有问题我不明白它是如何错过权限,虽然我从使用P12密钥而不是client_secrets.json文件复制它的代码。

任何指针都将受到赞赏。 谢谢。

请尝试添加应用程序所需的范围信息。

正如Method: spreadsheets.batchUpdate中所述,需要以下OAuth范围之一:

  • https://www.googleapis.com/auth/spreadsheets
  • try { throw new TypeError("Error message"); } catch (e){ console.log((<Error>e).message);//conversion to Error type }

Google表格API的可用OAuth 2.0范围信息列在Authorizing requests with OAuth 2.0中,除此之外,此SO帖子中提供的解决方案 - Google spreadsheet api Request had insufficient authentication scopes也可能有所帮助。
