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 IDE、IntelliJ 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 Explorer、DevStar、CodeLabs、SDK 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:
在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 IDE,API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Goland、Pycharm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。
https://developer.huaweicloud.cn/develop/toolkit.html
IDE安装
- 在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。
- Plugins区域单击Marketplace,在搜索栏中输入Huawei Cloud API。
- Search Results区域会出现Huawei Cloud API,单击Install,完成后重启IDE。
离线包安装:
- 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。。
- 在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。
- 在Plugins区域单击 ,再单击Install Plugin from Disk...。
- 在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。

4 抓住偷偷藏不住的你
4.1 前期准备
华为云提供了人脸识别服务端SDK,您可以直接集成服务端SDK来调用人脸识别服务的相关API,从而实现对人脸识别服务的快速操作。
该示例展示了如何通过Java版SDK实现人脸识别。
开发前准备:
- 已注册华为云,并完成实名认证 。
- 已订阅人脸识别服务。
- 已具备开发环境,支持Java JDK 1.8及其以上版本。
- 已获取华为云账号对应的Access Key(AK)和Secret Access Key(SK)。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 。
- 已获取直播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。
安装SDK:
您可以通过Maven配置所依赖的人脸识别服务SDK
<dependency>
<groupId>com.huaweicloud.sdk</groupId>
<artifactId>huaweicloud-sdk-frs</artifactId>
<version>3.1.19</version>
</dependency>
开始使用:
导入依赖模块
import com.huaweicloud.sdk.core.auth.ICredential;
import com.huaweicloud.sdk.core.auth.BasicCredentials;
import com.huaweicloud.sdk.core.exception.ConnectionException;
import com.huaweicloud.sdk.core.exception.RequestTimeoutException;
import com.huaweicloud.sdk.core.exception.ServiceResponseException;
//v2版本sdk
import com.huaweicloud.sdk.frs.v2.region.FrsRegion;
import com.huaweicloud.sdk.frs.v2.*;
import com.huaweicloud.sdk.frs.v2.model.*;
初始化认证信息
public static ICredential getCredential(String ak, String sk) {
return new BasicCredentials()
.withAk(ak)
.withSk(sk);
}
相关参数说明如下所示:
ak:华为云账号Access Key。
sk:华为云账号Secret Access Key 。
初始化人脸识别服务的客户端
public static FrsClient getClient(Region region, ICredential auth) {
// 初始化人脸识别服务的客户端
return FrsClient.newBuilder()
.withCredential(auth)
.withRegion(region) // 选择服务所在区域 FrsRegion.CN_NORTH_4
.build();
}
相关参数说明如下所示:
service region: 服务所在区域,例如:
CN_NORTH_1 北京一
CN_NORTH_4 北京四
