PHP SDK

本章节介绍新版PHP SDK，您可以参考本章节进行快速集成开发。

准备工作

注册华为账号并开通华为云，并完成实名认证，账号不能处于欠费或冻结状态。
已具备开发环境，PHP 5.6 及以上版本，可执行 php --version 检查当前的版本信息。
登录“我的凭证 > 访问秘钥”页面，获取Access Key（AK）和Secret Access Key（SK）。
图1 获取AK、SK
登录“我的凭证”页面，获取“IAM用户名”、“账号名”以及待使用区域的“项目ID”。调用服务时会用到这些信息，请提前保存。
本样例以“华北-北京四”区域为例，获取对应的项目ID（project_id）。

图2 我的凭证

安装SDK

推荐使用 Composer 安装 SDK 。

Composer 是 php 的依赖管理工具，允许您在项目中声明依赖关系并安装这些依赖：

// 安装 Composer
curl -sS https://getcomposer.org/installer | php
// 安装 PHP SDK
composer require huaweicloud/huaweicloud-sdk-php

安装完毕后，你需要引入 Composer 的自动加载文件：

require 'path/to/vendor/autoload.php';

开始使用

在开始使用之前，请确保您安装的是最新版本的SDK。使用过时的版本可能会导致兼容性问题或无法使用最新功能。您可以通过运行以下命令来检查并更新SDK至最新版本。

composer show huaweicloud/huaweicloud-sdk-php
composer update huaweicloud/huaweicloud-sdk-php

详细的SDK介绍，使用异步客户端，配置日志请参见SDK中心、PHP SDK使用指导、PHP SDK使用视频。

导入依赖模块

<?php
namespace HuaweiCloud\SDK\Frs\V2\Model;
require_once "vendor/autoload.php";
use HuaweiCloud\SDK\Core\Auth\BasicCredentials;
use HuaweiCloud\SDK\Core\Http\HttpConfig;
use HuaweiCloud\SDK\Core\Exceptions\ConnectionException;
use HuaweiCloud\SDK\Core\Exceptions\RequestTimeoutException;
use HuaweiCloud\SDK\Core\Exceptions\ServiceResponseException;
use HuaweiCloud\SDK\Frs\V2\FrsClient;

配置客户端连接参数

默认配置

// 使用默认配置
$config = HttpConfig::getDefaultConfig();

网络代理（可选）

// 使用代理服务器
$config->setProxyProtocol('http');
$config->setProxyHost('proxy.huawei.com');
$config->setProxyPort(8080);
$config->setProxyUser('username');
$config->setProxyPassword('password');

超时配置（可选）

// 默认连接超时时间为60秒，读取超时时间为120秒。可根据需要修改默认值。
$config->setTimeout(120);
$config->setConnectionTimeout(60);

SSL配置（可选）

// 配置跳过服务端证书验证
$config->setIgnoreSslVerification(true);
// 配置服务器端CA证书，用于SDK验证服务端证书合法性
$config->setCertFile("{yourCertFile}");

配置认证信息
配置AK、SK、projectId信息。华为云通过AK识别用户的身份，通过SK对请求数据进行签名验证，用于确保请求的机密性、完整性和请求者身份的正确性。
```
// 终端节点以 FRS 服务北京四的 endpoint 为例

$ak = getenv('HUAWEICLOUD_SDK_AK');
$sk = getenv('HUAWEICLOUD_SDK_SK');
$endpoint = "https://face.cn-north-4.myhuaweicloud.com";
$projectId = getenv('PROJECT_ID');
$credentials = new BasicCredentials($ak,$sk,$projectId);
```
认证参数说明：
- ak、sk：访问秘钥信息，获取方法请参见准备工作。
- projectId：华为云项目ID，获取方法请参见准备工作。
- endpoint：华为云各服务应用区域和各服务的终端节点，详情请查看地区和终端节点。
- 认证用的 ak 和sk 硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全。
- 本示例以 ak 和 sk 保存在环境变量中来实现身份验证为例，运行本示例前请先在本地环境中设置环境变量HUAWEICLOUD_SDK_AK，HUAWEICLOUD_SDK_SK和PROJECT_ID。
图3 Windows环境新建环境变量

初始化客户端

指定云服务endpoint方式

$client = FrsClient::newBuilder(new FrsClient)
  ->withHttpConfig($config)
  ->withEndpoint($endpoint)
  ->withCredentials($credentials)
  ->build();

发送并查看响应

// 以调用人脸检测接口 DetectFaceByBase64 为例
$request = new DetectFaceByBase64Request();
$body = new FaceDetectBase64Req();
$body->setImageBase64("图片的base64编码");
$request->setBody($body);
try {
  $response = $client->DetectFaceByBase64($request);
} catch (ConnectionException $e) {
  $msg = $e->getMessage();
  echo "\n". $msg ."\n";
} catch (RequestTimeoutException $e) {
  $msg = $e->getMessage();
  echo "\n". $msg ."\n";
} catch (ServiceResponseException $e) {
  echo "\n";
  echo $e->getHttpStatusCode(). "\n";
  echo $e->getErrorCode() . "\n";
  echo $e->getErrorMsg() . "\n";
}
echo "\n";
echo $response;

使用人脸比对SDK时，image1、image2参数需为相同类型，即同为url、base64或file。

异常处理

表1 异常处理
一级分类	一级分类说明	二级分类	二级分类说明
ConnectionException	连接类异常	HostUnreachableException	网络不可达、被拒绝。
ConnectionException	连接类异常	SslHandShakeException	SSL认证异常。
RequestTimeoutException	响应超时异常	CallTimeoutException	单次请求，服务器处理超时未返回。
RequestTimeoutException	响应超时异常	RetryOutageException	在重试策略消耗完成后，仍无有效的响应。
ServiceResponseException	服务器响应异常	ServerResponseException	服务端内部错误，Http响应码：[500,]。
ServiceResponseException	服务器响应异常	ClientRequestException	请求参数不合法，Http响应码：[400, 500)

// 捕获和处理不同类型的异常
try {
  $response = $client->DetectFaceByBase64($request);
} catch (ConnectionException $e) {
  $msg = $e->getMessage();
  echo "\n". $msg ."\n";
} catch (RequestTimeoutException $e) {
  $msg = $e->getMessage();
  echo "\n". $msg ."\n";
} catch (ServiceResponseException $e) {
  echo "\n";
  echo $e->getHttpStatusCode(). "\n";
  echo $e->getErrorCode() . "\n";
  echo $e->getErrorMsg() . "\n";
}
echo "\n";
echo $response;
