如何使用Python从Azure中的存储帐户获取大小详细信息。

我在我的环境中尝试了一下，得到了以下结果：

最初，我创建了应用程序来获取Client-id，tenant-id和Client-secret。

为订阅级下的**appvenkat分配了contributor**角色。

我试着用同样的代码进行最小的修改，我可以使用Python获取存储帐户的已使用容量。

代码：

import requests
    from datetime import datetime, timedelta
    
    start_time = (datetime.utcnow() - timedelta(hours=23)).replace(microsecond=0).isoformat() + "Z"
    end_time = (datetime.utcnow() - timedelta(hours=22)).replace(microsecond=0).isoformat() + "Z"
    
    
    subscription_id = "your subscription id"
    resource_group = "your resourcegroup name"
    storage_account_name = "your storage account name"
    metric_name = "UsedCapacity" 
    time_range = f"{start_time}/{end_time}"  
    api_version = "2021-05-01"
    
    tenant_id = "your tenant id"
    client_id = "your client id"
    client_secret = "your client secret
    
    token_endpoint = f"https://login.microsoftonline.com/{tenant_id}/oauth2/token" 
    
    data = {
      "grant_type": "client_credentials",
      "client_id": f"{client_id}",  
      "client_secret": f"{client_secret}",  
      "resource": "https://management.azure.com/"
    }
    
    response = requests.post(token_endpoint, data=data)
    
    if response.status_code == 200:
      post_response = response.text
      #print("POST_Response:",post_response)
      access_token = response.json()["access_token"]
    #   print("Access Token:", access_token)
    else:
      print("Error generating access token:", response.status_code)
    
    
    headers = {
      "Authorization": f"Bearer {access_token}",
      "Content-Type" : "application/json"
    }
    
    
    api_url = f"https://management.azure.com/subscriptions/{subscription_id}/resourceGroups/{resource_group}/providers/Microsoft.Storage/storageAccounts/{storage_account_name}/providers/microsoft.insights/metrics?timespan={time_range}&metricnames={metric_name}&api-version={api_version}"
    
    
    print("API:",api_url)
    
    response = requests.get(api_url,headers=headers)
    print(response)
    print (response.headers)
    print(response.text)

输出：
