# 图像内容审核（V3）
1. 本章节对图像内容审核AK/SK方式使用SDK进行示例说明。 示例代码中可以使用Url或Image配置图像信息(代表使用url或者图像的base64)，示例中以url为例配置完成后运行即可。
   项目ID的获取请参考[获取项目ID](https://support.huaweicloud.com/api-moderation/moderation_03_0055.html)。

   // 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和HUAWEICLOUD_SDK_SK、HUAWEICLOUD_SDK_PROJECT_ID。 
   $ak = getenv('HUAWEICLOUD_SDK_AK');
