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： 
    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
            WithCredential(auth).
            Build())

    request := &model.RunImageMediaTaggingRequest{}
    thresholdImageMediaTaggingReq:= float32(10)
    languageImageMediaTaggingReq:= "zh"
    urlImageMediaTaggingReq:= "https://XXX.jpg"  //此处替换为公网可以访问的图片地址
    request.Body = &model.ImageMediaTaggingReq{
        Threshold: &thresholdImageMediaTaggingReq,
        Language: &languageImageMediaTaggingReq,
        Url: &urlImageMediaTaggingReq,
    }
    response, err := client.RunImageMediaTagging(request)
    if err == nil {
        fmt.Printf("%+v\n", response)
    } else {
        fmt.Println(err)
    }
}
  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。
