工作原理

该脚本使用高级 YouTube 服务获取 YouTube 视频详细信息和 每个工作表的视频链接列中列出的视频网址的统计信息。 如果所列视频的评论数增加了,脚本会向 发送电子邮件通知,该通知会发送到该工作表命名的电子邮件地址。

Apps 脚本服务

此解决方案使用以下服务:

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)。
  • 可以访问互联网的网络浏览器。

设置脚本

创建 Apps 脚本项目

  1. 点击以下按钮创建跟踪 YouTube 视频观看次数和 评论电子表格。Apps 脚本项目 此解决方案会附加到电子表格中。
    复制
  2. 在复制的电子表格中,更改 Your_Email_Address 的名称。 工作表复制到您的电子邮件地址。
  3. 添加您要跟踪的 YouTube 视频网址,或使用提供的网址 测试。网址必须以 www.youtube.com/watch?v= 格式开头。
  4. 点击附加信息 > Apps 脚本。如果 YouTube 已列在服务下,您可以跳至下一类 2 个步骤。
  5. 服务旁边,点击“添加服务”
  6. 从列表中选择 YouTube Data API,然后点击添加

创建触发器

  1. 在 Apps 脚本项目中,点击触发器 > 添加触发器
  2. 选择要运行的函数部分,选择 markVideos
  3. 选择事件来源部分,选择时间驱动
  4. 选择基于时间的触发器类型部分,选择天计时器
  5. 选择时段部分,选择您的首选时间。
  6. 出现提示时,为脚本授权。 如果 OAuth 同意屏幕显示以下警告:“此应用未经验证”, 选择高级 > 以继续 前往“{Project Name}”(不安全)

运行脚本

您设置的触发器每天运行一次脚本。您可以运行该脚本 以便进行测试

  1. 在 Apps 脚本项目中,点击 Editor(编辑器)
  2. 在函数下拉菜单中,选择 markVideos
  3. 点击运行
  4. 切换回电子表格,查看脚本添加到的信息 。
  5. 打开您的电子邮件,查看电子邮件,其中包含更多视频 评论数量超过零。当该脚本将来运行时,它只会发送一个 通过电子邮件分享自上次 脚本。
