用python操作JSON

我试图操纵JSON数据，以匹配Ansible的特定格式。我对python和一般编程都是新手。我似乎不太明白怎么做。这是我的相关代码：

import os
import sys
import argparse
import ConfigParser

try:
    import json
except ImportError:
    import simplejson as json

import requests

payload = 'query=SELECT+TOP+10+IPAddress,+Vendor+FROM+Orion.Nodes'
url = "https://10.150.199.44:17778/SolarWinds/InformationService/v3/Json/Query"
req = requests.get(url, params=payload, verify=False, auth=('dmitry', 'security'))

jsonget = req.json()


def get_list(self):
        hostsData = jsonget
        print "Test json before manipulation:\n"
        print(hostsData)
        print "\n\n"
        for item in hostsData['results']:
            print '' + item['Vendor']
            for item in hostsData['results']:
                print 'hosts:' + item['IPAddress']

这是我的输出：

./swinds.py --list
Test json before manipulation:

{u'results': [{u'Vendor': u'Cisco', u'IPAddress': u'10.150.190.2'}, {u'Vendor': u'Cisco', u'IPAddress': u'10.150.250.3'}, {u'Vendor': u'Unknown', u'IPAddress': u'10.255.255.42'}, {u'Vendor': u'Juniper Networks/NetScreen', u'IPAddress': u'10.58.1.1'}, {u'Vendor': u'Cisco', u'IPAddress': u'10.33.93.1'}, {u'Vendor': u'Cisco', u'IPAddress': u'10.33.93.2'}, {u'Vendor': u'Unknown', u'IPAddress': u'10.33.93.3'}, {u'Vendor': u'Cisco', u'IPAddress': u'10.33.93.4'}, {u'Vendor': u'Unknown', u'IPAddress': u'10.33.93.6'}, {u'Vendor': u'Cisco', u'IPAddress': u'10.33.93.7'}]}



    Cisco
hosts:10.150.190.2
hosts:10.150.250.3
hosts:10.255.255.42
hosts:10.58.1.1
hosts:10.33.93.1
hosts:10.33.93.2
hosts:10.33.93.3
hosts:10.33.93.4
hosts:10.33.93.6
hosts:10.33.93.7
Cisco
hosts:10.150.190.2
hosts:10.150.250.3
hosts:10.255.255.42
hosts:10.58.1.1
hosts:10.33.93.1
hosts:10.33.93.2
hosts:10.33.93.3
hosts:10.33.93.4
hosts:10.33.93.6
hosts:10.33.93.7
Unknown
...

我要做的是输出类似于Ansible的内容：

{
    "Cisco"   : {
        "hosts"   : [ "10.150.190.2", "10.150.250.3" ],
            },
    "Unknown"  : 
        "hosts"   : [ "10.255.255.42" ],
},

谢谢你的帮助

# Your long string

# Eval the Json to python friendly dict
dumped = eval(simplejson.dumps(s))

# Make a set of vendors (no duplicates)
vendor_set = set()
for value in dumped['results']:
    vendor_set.add(value['Vendor'])

# Make a new dict based on these vendors
final_dict = dict.fromkeys(vendor_set)

# Loop over the dict, conditionally adding IPAddresses to the hosts key for each vendor
for key in final_dict:
    for v in dumped['results']:
        if final_dict[key] is not None:
            if key in str(v):
                final_dict[key]['hosts'].append(v['IPAddress'])
        else:
            final_dict[key] = {'hosts': []}

# Print it (somewhat) nicely
pprint.pprint(final_dict)

# Prints:

                     '10.33.93.7']},
 'Juniper Networks/NetScreen': {'hosts': ['10.58.1.1']},
 'Unknown': {'hosts': ['10.255.255.42', '10.33.93.3', '10.33.93.6']}}

这些是该服务器的真实凭据吗？URL是否真实？？：ODude……….发布前对数据进行匿名………

10.0.0.0/24

是专用网络…问题是否与将一种结构转换为另一种结构有关？Dmitry，它是从测试环境中的Orion测试版本中提取的样本数据。还有RFC1918地址。我是编程新手，不是网络/秒。谢谢你的关心，明白了。我需要所有iPaddes都位于组下（供应商密钥）。这就是为什么我有这个循环。请注意下面的Cisco，然后在下面的主机键中输入所有IPAddress值。这就是ansible读取库存数据的方式。{“Cisco”：{“hosts”：[“10.150.190.2”，“10.150.250.3”]，}，“未知”：“hosts”：[“10.255.255.42”]，}，请尝试此^@FunkyClicker。已关闭。当我运行它时，我会在末尾得到一个空值，ansible不喜欢/swinds.py--列出{'Cisco'：{'hosts'：['10.150.250.3'，'10.33.93.1'，'10.33.93.2'，'10.33.93.4'，'10.33.93.7']}，'Juniper Networks/NetScreen'：{'hosts'：['10.58.1.1']}，'未知'：{'hosts'：['10.255.255.42'，'10.33.93.3'，'10.33.93.6']}。我无法重现那个问题。当我执行一个包含我的确切代码的python文件时，我不会得到那个结果。这可能来自您原来的长字符串（我分配给's'）。。。这里可能有空值吗？我的意思是，在最坏的情况下，您可以通过使用

pprint.pprint（eval（str（final_dict.replace（'null'，''）））

来消除它，但我建议您在时间允许的情况下，从您这边找到它的来源。
