# 翻拍识别示例
本章节对翻拍识别AK/SK方式使用SDK进行示例说明。
- 翻拍识别示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用初始化RunRecaptureDetectReq中的Image或Url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](https://developer.huaweicloud.com/endpoint?Image)。
1. 翻拍识别调用示例代码如下：
   ```
   package main
    
   import (
       "fmt"
       "github.com/huaweicloud/huaweicloud-sdk-go-v3/core/auth/basic"
       image "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/image/v2"
       "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/image/v2/model"
       region "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/image/v2/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).
           Build()
    
       client := image.NewImageClient(
           image.ImageClientBuilder().
               WithRegion(region.ValueOf("cn-north-4")).  //此处替换为您开通服务的区域，详情请查看地区和终端节点.
               WithCredential(auth).
               Build())
    
       request := &model.RunRecaptureDetectRequest{}
       thresholdRecaptureDetectReq:= float32(0)
       urlRecaptureDetectReq:= "https://bucketname.obs.cn-north-4.myhuaweicloud.com/image/test1.jpg"//替换为公网可以访问的图片地址
       request.Body = &model.RecaptureDetectReq{
          Threshold: &thresholdRecaptureDetectReq,
          Url: &urlRecaptureDetectReq,
       }
       response, err := client.RunRecaptureDetect(request)
       if err == nil {
           fmt.Printf("%+v\n", response)
       } else {
           fmt.Println(err)
       }
   }
   ```
   
2. 识别结果输出到控制台表示执行成功。
   ```
   {"result":{"suggestion":"false","category":"recapture","score":"0.9998","detail":[{"label":"recapture","confidence":"0.9998"}]}}
   ```
