发送精选内容

编码级别：初级
时长：20 分钟
项目类型：使用事件驱动型触发器的自动化操作

目标

  • 了解该解决方案的用途。
  • 了解 Apps Script 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

如果您想向观众提供多种类型的内容，可以使用 Google 表单让用户选择要接收的内容。借助此解决方案，用户可以选择自己感兴趣的主题，然后系统会自动向他们发送所选内容的电子邮件。

演示：使用 Google 表单和 Gmail 发送内容

运作方式

该脚本会安装一个事件驱动型触发器，每当用户提交表单时，该触发器就会运行。每当有用户提交表单时，该脚本都会根据 Google 文档模板创建并发送电子邮件。该电子邮件包含用户的姓名和他们选择的内容。您提供的内容可以是任何类型，只要能通过网址引用即可。

Apps 脚本服务

此解决方案使用以下服务：

  • 脚本服务 - 安装事件驱动型触发器，该触发器会在有人提交表单时触发。
  • 文档服务 - 打开脚本用于创建电子邮件的 Google 文档模板。
  • 邮件服务 - 使用用户的姓名和所选内容创建并发送电子邮件。
  • 电子表格服务 - 在脚本发送电子邮件后，将确认信息添加到表单回复表格中。

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）。
  • 一个能够访问互联网的网络浏览器。

设置脚本

  1. 点击以下按钮，复制发送精选内容电子表格。此解决方案的 Apps 脚本项目已附加到电子表格中。
    复制

  2. 在复制的电子表格中，依次点击扩展 > Apps 脚本。

  3. 在“函数”下拉菜单中，选择 installTrigger。

  4. 点击运行。

  5. 根据提示为脚本授权。如果 OAuth 意见征求界面显示此应用未经验证警告，请依次选择高级 > 前往 {Project Name}（不安全）以继续操作。

重要提示：如果您多次运行 installTrigger，该脚本会创建多个触发器，每个触发器都会在用户提交表单时发送一封电子邮件。如需删除多余的触发器并避免重复发送电子邮件，请点击触发器 。右键点击每个额外的触发器，然后点击删除触发器。

运行脚本

  1. 切换回电子表格，然后依次点击工具 > 管理表单 > 前往实际表单。
  2. 填写表单，然后点击提交。
  3. 请查看您的电子邮件，看看是否收到了包含您所选内容链接的电子邮件。
