如何将JSON对象键写入CSV文件？

Question

当前正在使用脚本从联机环境资产列表中查询某些资产信息。下面是输出大量JSON对象数据的脚本。忽略一些未使用的导入

（注意tenableIO的方法是pyTenable包的一部分，但只知道它返回JSON对象，所以我不一定需要使用json.load函数。）

from pprint import pprint
from tenable.io import TenableIO
import time
import json
import os
import datetime
import csv

# filter variables to request specific assets from the api

last_month = int(time.time()) - 2629743
source_list = ["AZURE"]

# TenableIO by default uses environmental variables stored locally for api keys

tio = TenableIO()

for asset in tio.exports.assets(sources=source_list, updated_at=last_month):
    hostname = asset['hostnames']
    ipv4 = asset['ipv4s']
    print(hostname, ipv4)

此脚本的大部分内容直接来自有关如何导出资产列表的可维护文档。我正在努力解决的问题是资产JSON数据的输出

脚本似乎正在正确解析json数据，并按预期返回以下输出（使用填充名和IP，因为这是私有数据）

['abc123'] ['XX.XX.XX.XX']
['def456'] ['XX.XX.XX.XX']
['ghi789'] ['XX.XX.XX.XX', 'YY.YY.YY.YY', 'ZZ.ZZ.ZZ.ZZ']

如何获取此输出并将其写入csv文件？更具体地说，如何使列1作为主机名，列2作为ip addreses，其中多个值与其键一起存储，而不是作为单独的列存储

即，此表格格式为csv：

Hostnames | IP Address
1. abc123 | XX.XX.XX.XX
2. def456 | XX.XX.XX.XX
3. ghi789'| XX.XX.XX.XX
            YY.YY.YY.YY
            ZZ.ZZ.ZZ.ZZ
4. jkl123 | XX.XX.XX.XX

根据请求添加JSON结构：

如果您希望将输出写入csv，那么可以通过python csv模块实现这一点

import csv
fields = ['Hostnames', 'IP Address']
filename = "myfile.csv"

li1 = [['abc123'],['XX.XX.XX.XX']]
li2 = [['def456'],['XX.XX.XX.XX']]
li3 = [['ghi789'],['XX.XX.XX.XX']]
li4 = [None, ['YY.YY.YY.YY']]
li5 = [None, ['ZZ.ZZ.ZZ.ZZ']]
rows = [li1, li2, li3, li4, li5]

with open(filename, 'w') as csvfile:  
    csvwriter = csv.writer(csvfile)   
    csvwriter.writerow(fields)
    for row in rows:   
        csvwriter.writerow(row)
