1、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。

2、API 插件安装--IntelliJ IDEA

2.1 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.com/develop/toolkit.html


IDE 安装


  1. 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。

  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. 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。

  3. 在 Plugins 区域单击 ，再单击 Install Plugin from Disk...。

  4. 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。

3、抓住偷偷藏不住的你

3.1 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>
复制代码


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;
复制代码


//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.*;
复制代码


初始化认证信息


public static ICredential getCredential(String ak, String sk) {
    return new BasicCredentials()
            .withAk(ak)
            .withSk(sk);
}
复制代码


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();
}
复制代码


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
