云服务、API、SDK，调试，查看，我都行

阅读短文您可以学习到：人工智能AI人脸的识别、检测、搜索、比对

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。

2.2 华为云API

左侧展示API列表，可以查询所有API，目前云服务206，APIs9213


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>

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
