跟踪 YouTube 视频观看次数和评论

编码级别:新手
时长:20 分钟
项目类型:通过时间驱动的触发器实现自动化

目标

  • 了解解决方案的用途。
  • 了解 Apps 脚本服务在此解决方案中执行的操作。
  • 设置脚本。
  • 运行脚本。

关于此解决方案

此解决方案使用 Google 表格跟踪公开 YouTube 视频的表现,包括观看次数、顶的次数和评论数。该触发器会每天检查更新的信息,并在视频有新的评论活动时发送电子邮件,以便您提出问题和发表评论。

运作方式

该脚本使用高级 YouTube 服务获取每个工作表中视频链接列中列出的视频网址的 YouTube 视频详细信息和统计信息。如果所列视频的评论数量增加,脚本会向以该工作表命名的电子邮件地址发送一封电子邮件通知。

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 帐号(Google Workspace 帐号可能需要管理员批准)。
  • 一个能够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的副本。此解决方案的 Apps 脚本项目已附加到该电子表格中。
    复制
  2. 在复制的电子表格中,将 Your_Email_Address 表格的名称更改为您的电子邮件地址。
  3. 添加您要跟踪的 YouTube 视频网址,或使用提供的网址进行测试。这些网址必须以 www.youtube.com/watch?v= 格式开头。
  4. 点击扩展程序 > Apps 脚本。如果 YouTube 已列在 Services 下,您可以跳到接下来的两个步骤。
  5. 点击服务旁边的“添加服务”图标
  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,依次点击触发器 > 添加触发器
  2. 对于选择要运行的函数,选择 markVideos
  3. 对于选择事件来源,选择时间驱动
  4. 对于选择基于时间的触发器类型,选择天计时器
  5. 选择时间部分,选择您的首选时间。
  6. 出现提示时,授权脚本。如果 OAuth 同意屏幕显示 This app is not verified(此应用未经验证)警告,请依次选择 Advanced > Go to {Project Name} (unsafe),继续操作。

运行脚本

您设置的触发器每天运行一次脚本。您可以手动运行该脚本以对其进行测试。

  1. 在 Apps 脚本项目中,点击 Editor 图标
  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,查看脚本添加到工作表中的信息。
  5. 打开您的电子邮件,查看包含评论数超过零的视频列表的电子邮件。以后运行时,该脚本只会发送一封电子邮件,其中包含自上次运行脚本以来评论数增加了的视频。
