填充团队假期日历

编码水平：初级
时长：15 分钟
项目类型：使用定时触发器实现的自动化

目标

• 了解解决方案的功能。
• 了解 Apps 脚本服务在解决方案中的作用。
• 设置脚本。
• 运行脚本。

关于此解决方案

共享休假日历是助力团队协作的绝佳工具；每个人都可以一目了然地确定谁在什么时候休假。此解决方案让您可以查看同事的休假时间，无需任何手动输入。

运作方式

此解决方案会根据 Google 群组中每个人的个人日历填充共享的假期日历。当有人安排休假时，他们会使用“休假”或“不在办公室”等关键字向自己的个人 Google 日历添加活动。

该脚本每小时扫描一次群组中成员的日历，并将合适的活动同步到共享日历。您可以更改脚本扫描新事件的频率。

此解决方案仅访问您的同事通过隐私设置向您公开的日历活动。

Apps 脚本服务

此解决方案使用以下服务：

• 群组服务 - 确定 Google 群组的成员。
• 日历高级服务 - 提供对 Google 日历 API 的访问权限，并搜索群组成员日历中的活动。

前提条件

如需使用此示例，您需要满足以下前提条件：

• Google 账号（Google Workspace 账号可能需要管理员批准）。
• 可访问互联网的网络浏览器。

设置脚本

创建团队休假日历

1. 打开 Google 日历。
2. 创建名为“团队休假”的新日历。
3. 在日历的设置中，找到集成日历，然后复制日历 ID。

创建 Apps 脚本项目

1. 点击以下按钮打开休假日历 Apps 脚本项目。
   打开项目
2. 点击概览 。
3. 在概览页面上，点击“复制”图标 。
4. 在复制的 Apps 脚本项目中，将变量 TEAM_CALENDAR_ID 设置为您之前创建的日历的 ID。
5. 将变量 GROUP_EMAIL 设置为包含团队成员的 Google 群组的电子邮件地址。
6. 点击服务旁边的“添加服务”图标 。
7. 选择 Google Calendar API，然后点击添加。

运行脚本

1. 在复制的 Apps 脚本项目中，从函数下拉菜单中选择 setup。
2. 点击运行。

3. 根据提示为脚本授权。 如果 OAuth 权限请求页面显示警告此应用未经过验证，请继续操作，依次选择高级 > 前往“{项目名称}”（不安全）。

4. 完成后，返回日历，确认“团队休假”日历已填充活动。
