我可以从API获取组和设备的JSON列表,但是键值不允许我在不操纵返回列表的情况下进行合并。不幸的是,必须使用单独的http请求检索组信息和设备信息。
获取组信息的代码如下所示:
#Python Code
import requests
import simplejson as json
import datetime
import pprintpp
print datetime.datetime.now().time()
url = 'https://www.somecompany.com/api/v2/groups/?fields=id,name'
s = requests.Session()
## Ver2 API Authenticaion ##
headers = {
'X-ABC-API-ID': 'nnnn-nnnn-nnnn-nnnn-nnnn',
'X-ABC-API-KEY': 'nnnnnnnn',
'X-DE-API-ID': 'nnnnnnnn',
'X-DE-API-KEY': 'nnnnnnnn'
}
r = json.loads(s.get((url), headers=headers).text)
print "Working...Groups extracted"
groups = r["data"]
print "*** Ver2 API Groups Information ***"
pprintpp.pprint (groups)
组的打印输出如下所示:
#Groups
[
{u'id': u'0001', u'name': u'GroupA'},
{u'id': u'0002', u'name': u'GroupB'},
]
获取设备信息的代码如下所示:
url = 'https://www.somecompany.com/api/v2/devicess/?limit=500&fields=description,group,id,name'
r = json.loads(s.get((url), headers=headers).text)
print "Working...Devices extracted"
devices = r["data"]
print "*** Ver2 API Devices Information ***"
pprintpp.pprint (devices)
设备输出如下所示:
#Devices
[
{
u'description': u'GroupB 100 (City State)',
u'group': u'https://www.somecompany.com/api/v2/groups/0002/',
u'id': u'90001',
u'name': u'ABC550-3e9',
},
{
u'description': u'GroupA 101 (City State)',
u'group': u'https://www.somecompany.com/api/v2/groups/0001/',
u'id': u'90002',
u'name': u'ABC500-3e8',
}
]
我想要做的是能够将两个JSON列表合并并排序为如下所示的输出:
#Desired Output
#Seperated List of GroupA & GroupB Devices
[
{u'id': u'0001', u'name': u'GroupA'},
{
u'description': u'GroupA 101 (City State)',
u'group': u'https://www.somecompany.com/api/v2/groups/0001/',
u'id': u'90002',
u'name': u'ABC500-3e8',
},
{u'id': u'0002', u'name': u'GroupB'},
{
u'description': u'GroupB 100 (City State)',
u'group': u'https://www.somecompany.com/api/v2/groups/0002/',
u'id': u'90001',
u'name': u'ABC550-3e9',
}
]
我遇到的一些问题是组和设备输出的关键名称不是唯一的。组中名为“id”的键实际上与设备中名为“group”的键的最后4位数字相同,并且是我希望用于排序的值。此外,组中的“id”和“name”与设备中的“id”和“name”不同。我极其有限的Python技能使这成为一项挑战。任何帮助指出我正确的解决方向将非常感激。

该程序产生您想要的输出:
import pprintpp
groups = [
{u'id': u'0001', u'name': u'GroupA'},
{u'id': u'0002', u'name': u'GroupB'},
]
devices = [
{
u'description': u'GroupB 100 (City State)',
u'group': u'https://www.somecompany.com/api/v2/groups/0002/',
u'id': u'90001',
u'name': u'ABC550-3e9',
},
{
u'description': u'GroupA 101 (City State)',
u'group': u'https://www.somecompany.com/api/v2/groups/0001/',
u'id': u'90002',
u'name': u'ABC500-3e8',
}
]
desired = sorted(
groups + devices,
key = lambda x: x.get('group', x.get('id')+'/')[-5:-1])
pprintpp.pprint(desired)
或者,如果lambda
似乎没有自我记录:
def key(x):
'''Sort on either the last few digits of x['group'], if that exists,
or the entirety of x['id'], if x['group'] does not exist.
'''
if 'group' in x:
return x['group'][-5:-1]
return x['id']
desired = sorted(groups + devices, key=key)
