问题： 从rest api GET
中存储的值创建json数据结构问题： 动态创建嵌套数据结构
用于检索值的Python代码：
url = 'https://ciscoprime.com/webacs/api/v2/data/ClientDetails.json?.nocount=True&.maxResults=2&.firstResult=0&.full=true'
get_response = requests.get(url, verify=False)
response = json.dumps(get_response.json())
resp = json.loads(response)
#variable = resp['queryResponse']['entity'][i]['clientDetailsDTO']['']
i = 0
clients = {}
while i < len(resp['queryResponse']['entity']):
clientID = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("@id")
associationTime = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("associationTime")
clientInterface = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("clientInterface")
connectionType = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("connectionType")
deviceIpAddress = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("deviceIpAddress")
deviceName = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("deviceName")
firstSeenTime = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("firstSeenTime")
ifIndex = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("ifIndex")
ipAddress = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("ipAddress")
macAddress = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("macAddress")

vlanName = resp.get("queryResponse", {}).get("entity", {})[i].get("clientDetailsDTO", {}).get("vlanName")
#print 'ClientID: {0}, associationTime: {1}, vlanName: {2}'.format(clientID, associationTime, vlanName)

以下代码可以满足您的需求。它找到id字段，然后遍历所有键并将它们添加到dict中，将id：{values}添加到主dict，我们将在末尾打印。
导入json

在您确切的上下文中，此代码将与您想要的字段一起使用：
import json
import requests
url = 'https://ciscoprime.com/webacs/api/v2/data/ClientDetails.json?.nocount=True&.maxResults=2&.firstResult=0&.full=true'
get_response = requests.get(url, verify=False)
response = json.dumps(get_response.json())
resp = json.loads(response)
clientlist = resp['queryResponse'].get('entity', [])
# Initialize my empty dict
formatted_clients = {}
search_keys = ["associationTime", "clientInterface", "connectionType", "deviceIpAddress", "deviceName", "firstSeenTime", "macAddress", "updateTime", "vendor", "vlan", "vlanName"]
if clientlist:
for client in clientlist:
# Initialize an empty client dict.
client_dict = {}
# Validate clientDetailsDTO
if "clientDetailsDTO" in client:
client_id = client['clientDetailsDTO'].get('@id', '')
if not client_id:
# Let's bail out if this doesn't exist
continue
for key in client['clientDetailsDTO'].keys():
# iterate through the keys, and add them to the client dict

# append the client_dict to formatted list

print(json.dumps(formatted_clients, indent=4))

您可以更新您的客户字典：
clients = []
for data in resp['queryResponse']['entity'] :
clientID = data.get("clientDetailsDTO", {}).get("@id")
associationTime = data.get("clientDetailsDTO", {}).get("associationTime")
clientInterface = data.get("clientDetailsDTO", {}).get("clientInterface")
connectionType = data.get("clientDetailsDTO", {}).get("connectionType")
deviceIpAddress = data.get("clientDetailsDTO", {}).get("deviceIpAddress")
deviceName = data.get("clientDetailsDTO", {}).get("deviceName")
firstSeenTime = data.get("clientDetailsDTO", {}).get("firstSeenTime")
ifIndex = data.get("clientDetailsDTO", {}).get("ifIndex")
ipAddress = data.get("clientDetailsDTO", {}).get("ipAddress")
macAddress = data.get("clientDetailsDTO", {}).get("macAddress")
updateTime = data.get("clientDetailsDTO", {}).get("updateTime")
vendor = data.get("clientDetailsDTO", {}).get("vendor")
vlan = data.get("clientDetailsDTO", {}).get("vlan")
vlanName = data.get("clientDetailsDTO", {}).get("vlanName")
clients.append({
'ClientID' : clientID,
'value' :
{
'associationTime' : associationTime,
'vlanName' : vlanName,
'connectionType' : connectionType
}
})
json.dumps(clients)
