在線調(diào)試和生成SDK示例

OpenAPI門戶提供在線調(diào)用云產(chǎn)品API、動態(tài)生成SDK示例代碼和快速檢索接口等功能，可以顯著降低使用API的難度。

前提條件

• 已創(chuàng)建AccessKey，詳情請參見創(chuàng)建AccessKey。

• 已安裝Python環(huán)境。

• 授予賬號相應(yīng)權(quán)限，詳情請參見授予RAM用戶權(quán)限。

安裝Alibaba Cloud SDK for Python

您可以通過pip安裝Python SDK，詳細說明請參見其他方式和開始使用。

pip install alibabacloud_hologram20220601==1.0.5

請求步驟

1. 導(dǎo)入相關(guān)產(chǎn)品的SDK。

   from alibabacloud_hologram20220601.client import Client as Hologram20220601Client
   from alibabacloud_tea_openapi import models as open_api_models
   from alibabacloud_hologram20220601 import models as hologram_20220601_models
   from alibabacloud_tea_util import models as util_models
   from alibabacloud_tea_util.client import Client as UtilClient

2. 設(shè)置AccessKey和域名，域名詳情請參見Hologres服務(wù)區(qū)域列表。

   說明

   建議使用環(huán)境變量的方式調(diào)用用戶名和密碼，降低密碼泄露風險。

   config = open_api_models.Config(
       # 您的AccessKey ID,
       access_key_id=os.environ['ALIBABA_CLOUD_USER'],
       # 您的AccessKey Secret,
       access_key_secret=os.environ['ALIBABA_CLOUD_PASSWORD']    
   )
   # 訪問的域名
   config.endpoint = 'hologram.cn-hangzhou.aliyuncs.com'
   client = Client(config)

3. 新建AcsClient。

   client = Client(config)

4. 創(chuàng)建Request對象（以查詢實例詳情GetInstance為例，1.0.3及以上版本無GetInstanceRequest），并設(shè)置請求參數(shù)。

   get_instance_request = GetInstanceRequest()

5. 調(diào)用返回結(jié)果。

   # 1.0.3之前版本
   response = client.get_instance('your_instanceId', get_instance_request)
   print(response)
   
   # 1.0.3及以上版本
   response = client.get_instance('your_instanceId')
   print(response)
