# 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。 示例代码中可以修改ImageDetectionReq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。
   服务所在的应用区域和终端节点，详情请查看 [地区和终端节点](https://developer.huaweicloud.com/endpoint?Moderation) 。

2. 控制台输出200即表示程序执行成功，[图像内容审核结果](https://support.huaweicloud.com/api-moderation/moderation_03_0086.html#section4)输出到控制台。
