1      Classroom和Toolkit的关系

1.1      Classroom的简介

classroom是基于华为云的云上软件教学服务,支持初级开发者和高校师生实现备课、上课、作业、考试、实验、实训等全教学流程的线上教学,提供多类习题自动判题、企业级DevOps实训、免费在线习题库等众多高级特性辅助进行数字化教学转型。

1.2      Toolkit插件之华为云API实战课程


2      IntelliJ IDEA 之API插件介绍

API插件支持 VS Code IDEIntelliJ IDEA等平台、以及华为云自研 CodeArts IDE,基于华为云服务提供的能力,帮助开发者更高效、便捷的搭建应用。API插件关联华为云服务下的 API ExplorerDevStarCodeLabsSDK 中心和 CLI 中心产品,致力于为开发者提供更稳定、快速、安全的编程体验。

在本插件中,我们提供了但不局限于如下的功能:

对接华为云API开放平台,支持用户检索API、查看API文档、调试API、以及提供SDK示例代码供用户学习如何使用API

提供华为云SDK代码片段补全功能,SDK依赖包自动引入,加速用户集成华为云API

对接华为云开发体验馆Codelabs,提供500+云服务代码示例,向导式教程帮助用户快速学习。

说明:

IntelliJ IDEA等系列平台和VS Code IDE,华为云API插件的名称是Huawei Cloud API。而在CodeArts IDEAPI插件是IDE原生内置的,名称是华为云API开发套件。

API插件在IntelliJ IDEA等系列平台和VS Code IDE的使用依赖底座插件,请提前安装底座插件。

3      API插件安装--IntelliJ IDEA

3.1    IntelliJ IDEA等平台

安装准备:下载并安装JDK1.8或更高版本。下载并安装IntelliJ IDEA 2020.2或更高版本。

须知:IntellIj平台同时支撑包括GolandPycharm等在内的IDE,若在其它相关IDE上开发,请下载配置好对应语言的编译器或者解释器。这里以IDEA为例介绍IntelliJ平台插件的安装流程,其他IntelliJ系列的IDE请参考IDEA

开始安装:

您可以在直接在IDE插件市场或者直接在JetBrains插件市场下载离线包安装。

IDE安装

  1. IntelliJ IDEA顶部菜单栏中选择File > Settings,在Settings对话框的左侧导航栏中单击Plugins
  2. Plugins区域单击Marketplace,在搜索栏中输入Huawei Cloud API
  3. Search Results区域会出现Huawei Cloud API,单击Install,完成后重启IDE


离线包安装:

  1. 进入插件市场搜索Huawei Cloud API,进入插件详情页,在Versions页签下选择想要版本的API插件,点击Download下载离线的插件压缩包保存到本地。。
  2. IntelliJ IDEA顶部菜单栏中选择File > Settings,在Settings对话框的左侧导航栏中单击Plugins
  3. Plugins区域单击 ,再单击Install Plugin from Disk...
  4. Choose Plugin File对话框中选择离线安装包(不用解压),并按照IntelliJ IDEA安装页面的提示,完成后续安装步骤。


说明:若当前您想要安装插件的IntelliJ IDE已经在桌面打开,则进入插件市场搜索Huawei Cloud API,进入插件详情页,在右上角会识别到本地已经打开的IDE,点击相应按钮,在弹出的IDE窗口中点击ok,则IDE后台会开始安装相应版本的API插件。

安装验证:在IntelliJ系列平台上安装插件成功后在左侧的导航栏中可以看到Huawei Cloud Toolkit图标,点击后面板会出现Huawei Cloud API的字样,则说明安装成功。

3.2      API列表


左侧展示API列表,可以查询所有API,目前云服务206APIs9213


华为云提供了文字识别服务端SDK,您可以直接集成服务端SDK来调用文字识别服务的相关API,从而实现对文字识别服务的快速操作。

该示例展示了如何通过goSDK实现文字识别。

前期准备:

已注册华为云,并完成 实名认证 。

已订阅文字识别服务。

已具备开发环境,支持go 1.14及其以上版本。

已获取华为云账号对应的Access KeyAK)和Secret Access KeySK)。请在华为云控制台“我的凭证 > 访问密钥”页面上创建和查看您的AK/SK。具体请参见访问密钥 。https://support.huaweicloud.cn/usermanual-ca/zh-cn_topic_0046606340.html

已获取文字识别服务对应区域的项目ID,请在华为云控制台“我的凭证 > API凭证”页面上查看项目ID。具体请参见 API凭证。https://support.huaweicloud.cn/usermanual-ca/ca_01_0002.html

环境配置:

// 启用go module

export GO111MODULE=on

export GONOSUMDB=*

//若下载不了sdk,则需要设置源

export GOPROXY=https://repo.huaweicloud.cn/repository/goproxy/,direct

安装SDK及代码依赖:

// 安装华为云Go

go get -u github.com/huaweicloud/huaweicloud-sdk-go-v3

// 安装依赖

go get github.com/json-iterator/go

go get github.com/huaweicloud/huaweicloud-sdk-go-v3/core/auth/signer@v0.1.2

go get github.com/huaweicloud/huaweicloud-sdk-go-v3/core/auth/provider@v0.1.2

go get github.com/huaweicloud/huaweicloud-sdk-go-v3/core/region@v0.1.2
