我在 google 中创建了服务帐户以访问和上传融合表中的数据。我能够使用 OAuth 进行身份验证并将数据推送到服务帐户的融合表中。但是当我尝试使用地图中的 tableid 访问同一个表时我无法访问相同的。创建的表未显示在我的主帐户中。我在 stackoverflow 中读到了一些问题，他们谈到了给予 FT 的许可（我什至做不到）

我的代码：

我在 stackoverflow 中读到了一些问题，他们谈到了给予 FT 的许可（我什至做不到）

您的代码已经包含它。看看你的 insertPermission() 方法。复制粘贴的奇迹... :)

根据 Google Maps 文档，您只能在地图上显示以“公共”或“未列出”形式共享的融合表。来源：https ://developers.google.com/maps/documentation/javascript/layers#FusionTablesSetup

要实现这一点，请使用角色“reader”在您的表上设置权限并输入“anyone”。有关更多信息和 java 示例，请参阅：https ://developers.google.com/drive/v2/reference/permissions/insert

Java 对我来说是希腊语……发布通用 FT Java 模块有什么意义？我在这里看不到任何 Google 地图代码，甚至看不到您尝试访问的表格 ID。使用 UI 到达您的餐桌：

https://www.google.com/fusiontables/DataSource?docid=[编码表ID]

在共享设置中，选择“在网络上公开”或“任何有链接的人”。现在应该可以通过 Google Maps javascript API 访问它了。
