媒资图像标签示例

本章节对媒资图像标签AK/SK方式使用SDK进行示例说明。

  • 媒资图像标签示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用ImageMediaTaggingReq中的Url或Image方法配置图像信息（image和url参数二选一），示例中以url为例，配置完成后运行即可。
  • endpoint是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 。
  1. 媒资图像标签调用示例代码如下： 
    <?php
namespace HuaweiCloud\SDK\Image\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\Image\V2\ImageClient;
   // 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CLOUD_SDK_AK和CLOUD_SDK_SK。
$ak = getenv('CLOUD_SDK_AK');
$sk = getenv('CLOUD_SDK_SK');
 //image.cn-north-4.myhuaweicloud.com替换为您开通服务区域的终端节点
$endpoint = "https://image.cn-north-4.myhuaweicloud.com"; 
$projectId = "";
$credentials = new BasicCredentials($ak,$sk,$projectId);
$config = HttpConfig::getDefaultConfig();
$config->setIgnoreSslVerification(true);
$client = ImageClient::newBuilder(new ImageClient)
  ->withHttpConfig($config)
  ->withEndpoint($endpoint)
  ->withCredentials($credentials)
  ->build();
$request = new RunImageMediaTaggingRequest();
$body = new ImageMediaTaggingReq();
$body->setLimit(10);
$body->setThreshold(60);
$body->setLanguage("zh");
$body->setImage("输入图片,使用base64编码");
$request->setBody($body);
try {
  $response = $client->RunImageMediaTagging($request);
  echo "\n";
  echo $response;
} 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->getRequestId(). "\n";
  echo $e->getErrorCode() . "\n";
  echo $e->getErrorMsg() . "\n";
}
  2. 执行示例代码文件，控制台输出媒资图像标签结果即表示程序执行成功。相关参数说明请参考媒资图像标签API。
