关于此解决方案

如果您有各种类型的内容要向观众提供，您可以可让用户选择通过 Google 表单从您那里接收哪些内容。通过此解决方案，用户可以选择自己感兴趣的主题，然后并自动通过电子邮件向其发送所选的内容。

使用 Google 表单和 Gmail 发送内容的演示

工作原理

该脚本会安装一个事件驱动型触发器，该触发器会在用户每次提交时运行表单。每次提交表单时，脚本都会创建从 Google 文档模板。电子邮件中包含用户的姓名以及用户看到的内容已选择。您提供的内容可以是任意类型，只要被引用网址。

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。
文档服务 - 系统会打开文档模板供脚本用来创建电子邮件的名称。
邮件服务 - 使用用户的名称和内容选择。
电子表格服务 - 添加确认信息到表单回复工作表。

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

点击以下按钮创建发送精选内容的副本电子表格。此 API 的 Apps 脚本项目解决方案。
复制
在您复制的电子表格中，点击附加信息 > Apps 脚本。
在函数下拉菜单中，选择 installTrigger。
点击运行。
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）。

重要提示：如果您多次运行 installTrigger，该脚本会创建多个触发器，每个触发器在用户提交表单时发送电子邮件。接收者请删除额外的触发器并避免收到重复的电子邮件，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

切换回电子表格，然后点击工具 > 管理表单 > 转到实时表单。
填写表单，然后点击提交。
请查收电子邮件，找到包含您所选内容的链接的电子邮件。
