用Python解析JSON数组

用Python解析JSON数组,python,arrays,json,parsing,Python,Arrays,Json,Parsing,我有一些JSON文件: { "cis" : [ { "ucmdbId" : "835cfedfaabc32a1358b322ff3bae056", "type" : "running_software", "properties" : { "display_label" : "jboss (site1.ru)" } }, { "ucmdbId" : "7ef9f21c132c12b3d8d2af0964cc5970", "typ

我有一些JSON文件:

{
  "cis" : [ {
    "ucmdbId" : "835cfedfaabc32a1358b322ff3bae056",
    "type" : "running_software",
    "properties" : {
      "display_label" : "jboss (site1.ru)"
    }
  }, {
    "ucmdbId" : "7ef9f21c132c12b3d8d2af0964cc5970",
    "type" : "node",
    "properties" : {
      "display_label" : "site2.ru"
    }
  } ],
  "relations" : [ {
    "ucmdbId" : "80c42edbe32fbb4c25621756ec9e09d2",
    "type" : "compound_f",
    "properties" : null,
    "end1Id" : "23e30baf2320a3274d0aa1e7f56cdaef",
    "end2Id" : "15af0ba134327d32a0c5c72450e63fcd"
  }, {
    "ucmdbId" : "7fe9fb15d4462d1212aeee4aef2f32b4",
    "type" : "compound_f",
    "properties" : null,
    "end1Id" : "23e30baf2320a3274d0aa327f56cdaef",
    "end2Id" : "9232dd2621b814da632932e8cd33ffc8"
  } ]
}
我只需要
cis
数组。这就是我需要解析的内容:

[{
  "ucmdbId" : "835cfedfaabc32a1358b322ff3bae056",
  "type" : "running_software",
  "display_label" : "jboss (site1.ru)"
 }, {
  "ucmdbId" : "7ef9f21c132c12b3d8d2af0964cc5970",
  "type" : "node",
  "display_label" : "site2.ru"
}]
Python脚本:

#!/usr/bin/python
import sys
import os
import tablib
import pandas as pd
import json
from pandas.io.json import json_normalize

f = open('/home/nik/test.json', 'rw')
jsonArray = f.read()
f.close
data = json.dumps(json.loads(jsonArray)['cis'])
jsonResult = pd.read_json(data)
array = json.loads(jsonArray)

print jsonArray
jsonResult.to_excel('/home/nik/output.xlsx', sheet_name='Sheet1')
但是我怎样才能得到关键参数呢?我尝试使用:

print data['type'].keys()
print data['type']
但它给了我一个错误:

AttributeError: 'str' object has no attribute 'keys'
如何获得正确的JSON格式

更新。解决方案:

谢谢,它起作用了。将JSON导出到xlsx文件的完整代码:

以上内容将为您提供cis数组。 下面是一个更精细的输出

for item in data['cis']:
    ucmdbId = (item['ucmdbId'])
    type = (item['type'])
    display_label = (item['properties']['display_label'])
    print(ucmdbId)
    print(type)
    print(display_label)
如果希望它与键标签一起使用,请使用

for item in data['cis']:
    ucmdbId = (item['ucmdbId'])
    type = (item['type'])
    display_label = (item['properties']['display_label'])
    print('ucmdbId:{}'.format(ucmdbId))
    print('type:{}'.format(type))
    print('display_label:{}'.format(display_label))

data['type']
返回类似于
“运行软件”
。这是一个字符串,不是字典。
数据['type']
将是一个
str
对象,即
“运行软件”
“节点”
。此对象没有
.key()
方法。你以为会发生什么?
for item in data['cis']:
    ucmdbId = (item['ucmdbId'])
    type = (item['type'])
    display_label = (item['properties']['display_label'])
    print(ucmdbId)
    print(type)
    print(display_label)
for item in data['cis']:
    ucmdbId = (item['ucmdbId'])
    type = (item['type'])
    display_label = (item['properties']['display_label'])
    print('ucmdbId:{}'.format(ucmdbId))
    print('type:{}'.format(type))
    print('display_label:{}'.format(display_label))
