# 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。
   ```
   package main
   import (
       "fmt"
       "github.com/huaweicloud/huaweicloud-sdk-go-v3/core/auth/basic"
       moderation "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/moderation/v3"
       "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/moderation/v3/model"
       region "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/moderation/v3/region"
   )
   func main() {
      // 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。
      ak := os.Getenv("HUAWEICLOUD_SDK_AK")
      sk := os.Getenv("HUAWEICLOUD_SDK_SK")
       auth := basic.NewCredentialsBuilder().
           WithAk(ak).
           WithSk(sk).
           WithProjectId(projectId).
           Build()
       client := moderation.NewModerationClient(
           moderation.ModerationClientBuilder().
               WithRegion(region.ValueOf("xxx")). //把xxx替换成服务所在的区域，例如北京四：cn-north-4。
               WithCredential(auth).
               Build())
       request := &model.CheckImageModerationRequest{}
       var listCategoriesbody = []string{
           "porn",
       }
       urlImageDetectionReq:= "http://www.xxxx.xxxx"
       request.Body = &model.ImageDetectionReq{
           Url: &urlImageDetectionReq,
           Categories: listCategoriesbody,
           EventType: "head_image",
       }
       response, err := client.CheckImageModeration(request)
       if err == nil {
           fmt.Printf("%+v\n", response)
       } else {
           fmt.Println(err)
       }
   }
   ```
   
2. 审核结果输出到控制台表示执行成功，[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。
