重要提示:本快速入门仅适用于网络会议服务提供商。

以下 Google Workspace 插件快速入门可将 Google 日历的功能扩展到 与虚构的网络会议服务(名为“我的网络会议”)同步。 修改日历活动时,该插件可让用户查看 将我的网络会议作为会议选项。

“快速入门”展示了会议创建和活动同步,但没有 在您将其连接到会议解决方案 API 之前,确保正常运行。

目标

  • 设置环境。
  • 设置脚本。
  • 运行脚本。

前提条件

设置环境

在 Google Cloud 控制台中打开您的 Cloud 项目

如果尚未打开,请打开您要使用的 Cloud 项目 示例:

  1. 在 Google Cloud 控制台中,前往选择项目页面。

    选择 Cloud 项目

  2. 选择您要使用的 Google Cloud 项目。或者,点击创建项目,然后按照屏幕上的说明操作。如果您创建的是 Google Cloud 项目,则可能需要为项目启用结算功能

启用日历 API

本快速入门使用 Google 日历高级服务,该服务 访问日历 API。

在使用 Google API 之前,您需要先在 Google Cloud 项目中启用这些 API。 您可以在单个 Google Cloud 项目中启用一个或多个 API。

    在您的 Google Cloud 项目中,启用日历 API。

    启用 API

Google Workspace 插件需要配置同意屏幕。正在配置 Google Workspace 插件的 OAuth 同意屏幕定义了 Google Workspace 插件 。

  1. 在 Google Cloud 控制台中,点击“菜单”图标 > API 和服务 > OAuth 同意屏幕

    转到 OAuth 同意屏幕

  2. 对于用户类型,选择内部,然后点击创建
  3. 填写应用注册表单,然后点击保存并继续
  4. 现在,您可以跳过添加范围,然后点击保存并继续。 以后,如果您要创建一款应用供用户使用 Google Workspace 组织,您必须将用户类型更改为外部,然后执行以下操作: 添加您的应用所需的授权范围。

  5. 查看应用注册摘要。如需进行更改,请点击修改。如果应用 点击 Back to Dashboard(返回信息中心)。

设置脚本

创建 Apps 脚本项目

  1. 如需创建新的 Apps 脚本项目,请前往 script.new
  2. 点击未命名项目
  3. 将 Apps 脚本项目重命名为会议插件,然后点击重命名
  4. 点击 Code.gs 文件旁边的“更多”图标 > 重命名。为文件命名 CreateConf
  5. 点击“添加文件”图标 > 脚本
  6. 将文件命名为 Syncing
  7. 将每个文件的内容替换为以下相应的代码:

    CreateConf.gs
