谷歌表 API（帶有 java）顯示“消息”：“請求的身份驗證范圍不足。”，“狀態”：“PERMISSION_DENIED”

Question

我正在使用谷歌表 API 來編輯驅動器上的谷歌表。 鏈接共享已開啟。 但這顯示以下錯誤：

Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden { "code": 403, "errors": [ { "domain": "global", "message": "Request had身份驗證范圍不足。”，“原因”：“禁止”}]，“消息”：“請求的身份驗證范圍不足。”，“狀態”：“PERMISSION_DENIED”}

我的代碼如下：

當您使用表格 API快速入門中的代碼時，我猜您首先生成了一個令牌來讀取電子表格，它只需要SheetsScopes.SPREADSHEETS_READONLY令牌並執行示例。

為了更新范圍，您需要刪除保存在TOKENS_DIRECTORY_PATH中的令牌文件，再次執行代碼並登錄。然后 Oauth2 將為您提供新的更新令牌。
