# 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](https://developer.huaweicloud.com/endpoint?Image)。
1. 媒资图像标签调用示例代码如下：
   ```
   # coding: utf-8
   from huaweicloudsdkcore.auth.credentials import BasicCredentials
   from huaweicloudsdkimage.v2.region.image_region import ImageRegion
   from huaweicloudsdkcore.exceptions import exceptions
   from huaweicloudsdkimage.v2 import *
   if __name__ == "__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")
       credentials = BasicCredentials(ak, sk) \
       client = ImageClient.new_builder() \
           .with_credentials(credentials) \
           .with_region(ImageRegion.value_of("cn-north-4")) \  //此处替换为您开通服务的区域
           .build()
       try:
           request = RunImageMediaTaggingRequest()
           request.body = ImageMediaTaggingReq(
               threshold=10,
               language="zh",
               url="https://XXX.jpg"  //此处替换为公网可以访问的图片地址
           )
           response = client.run_image_media_tagging(request)
           print(response)
       except exceptions.ClientRequestException as e:
           print(e.status_code)
           print(e.request_id)
           print(e.error_code)
           print(e.error_msg)
   ```
   
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](https://support.huaweicloud.com/api-image/image_03_0048.html#section5)。
