编码级别:中级
时长:30 分钟
项目类型:Google Workspace 插件

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。
  • 设置环境。
  • 设置脚本。
  • 运行脚本。

关于此解决方案

借助此解决方案,您可以在 Google 文档、表格和幻灯片中轻松翻译文本。

翻译 Google Workspace 插件的屏幕截图

运作方式

在 Google 文档、表格或幻灯片中选择文本,并点击插件中的获取选择内容时,脚本会将文本复制到插件中,对其进行翻译并显示译文。

默认情况下,脚本会检测源语言并将文本翻译成英语。您可以修改源语言和目标语言。

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。

  • 具有一个 Google Cloud 项目

设置您的环境

在 Google Cloud 控制台中打开您的 Cloud 项目

打开您打算用于此示例的 Cloud 项目(如果尚未打开):

  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。如果您创建了 Google Cloud 项目,则可能需要为该项目启用结算功能

Google Workspace 插件需要配置同意屏幕。通过配置插件的 OAuth 同意屏幕,可以定义 Google 向用户显示的内容。

  1. 在 Google Cloud 控制台中,依次点击“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. 目前,您可以跳过添加范围的步骤,点击 Save and Continue(保存并继续)。 将来,当您创建要在 Google Workspace 组织外部使用的应用时,必须将用户类型更改为外部,然后添加您的应用所需的授权范围。

  5. 查看您的应用注册摘要。如要进行更改,请点击修改。如果应用注册看起来正常,请点击 Back to Dashboard

设置脚本

创建 Apps 脚本项目

  1. 点击以下按钮,打开 Translate Apps 脚本项目。
    打开项目

  2. 点击概览

  3. 在概览页面上,点击“复制”图标 用于制作副本的图标

复制 Cloud 项目编号

  1. 在 Google Cloud 控制台中,依次点击“菜单”图标 > IAM 和管理 > 设置

    转到“IAM 和管理”设置

  2. 项目编号字段中,复制相应值。

设置 Apps 脚本项目的 Cloud 项目

  1. 在复制的 Apps 脚本项目中,点击项目设置 项目设置的图标
  2. Google Cloud Platform (GCP) 项目下,点击更改项目
  3. GCP 项目编号中,粘贴 Google Cloud 项目编号。
  4. 点击设置项目

安装测试部署

  1. 在复制的 Apps 脚本项目中,点击 Editor 图标
  2. 打开 Code.gs 文件,然后点击 Run。出现提示时,授权脚本。
  3. 点击部署 > 测试部署
  4. 依次点击安装 > 完成

运行脚本

  1. Google 文档表格幻灯片中打开文件,或创建新文件。
  2. 在右侧边栏中,打开谷歌翻译插件
  3. 如果系统提示,请授权该插件。
  4. 选择文件中的文本。
  5. 在该插件中,依次点击获取所选内容 > 翻译
