Question

我是新的json解析从python中的http api。当前我已经在python中将http内容解析为字符串，其中包含json对象数组我的代码如下所示

import json
from urllib.request import urlopen

apilink=urlopen("api link")


data=json.loads(apilink.read().decode())

print(data)

我当前的输出是

{'Message': 'Success', 'Data': '[{"Did":"c055c3d2f3314725b69965e6c55adb5b","InsertedDate":"2017-08-02 7:27:11 AM","UpdatedDate":"2017-08-02 9:33:16 AM","CreatedBy":"1","UpdatedBy":"1","Name":"Hello World","ModuleName":"Rpt_Hello_World","ApplicationName":"Asset Inventory","Published":"true","UserId":"1","PostProcessor":""}]', 'Status': 'Success'}

但我想只提取属性＆＃39;数据＆＃39;那是json数组

'Data': '[{"Did":"c055c3d2f3314725b69965e6c55adb5b","InsertedDate":"2017-08-02 7:27:11 AM","UpdatedDate":"2017-08-02 9:33:16 AM","CreatedBy":"1","UpdatedBy":"1","Name":"Hello World","ModuleName":"Rpt_Hello_World","ApplicationName":"Asset Inventory","Published":"true","UserId":"1","PostProcessor":""}]'

令人满意的部分是

[{＆＃34;＆＃34;：＆＃34; c055c3d2f3314725b69965e6c55adb5b＆＃34;，＆＃34; InsertedDate＆＃34;：＆＃34; 2017-08-02 7:27:11 AM＆＃34; ，＆＃34; UpdatedDate＆＃34;：＆＃34; 2017-08-02 9:33:16 AM＆＃34;，＆＃34; CreatedBy＆＃34;：＆＃34; 1＆＃34;，＆＃34 ; UpdatedBy＆＃34;：＆＃34; 1＆＃34;，＆＃34;姓名＆＃34;：＆＃34; Hello World＆＃34;，＆＃34; ModuleName＆＃34;：＆＃34; Rpt_Hello_World＆＃34 ;，＆＃34; ApplicationName＆＃34;：＆＃34;资产库存＆＃34;，＆＃34;已发布＆＃34;：＆＃34; true＆＃34;，＆＃34; UserId＆＃34;：＆＃ 34; 1＆＃34;＆＃34; PostProcessor中＆＃34;：＆＃34;＆＃34;}]

请帮助我解决这个问题。谢谢

Answer 1

data是一本字典。使用dict索引。您需要与Data关联的值：

In [876]: data['Data']
Out[876]: '[{"Did":"c055c3d2f3314725b69965e6c55adb5b","InsertedDate":"2017-08-02 7:27:11 AM","UpdatedDate":"2017-08-02 9:33:16 AM","CreatedBy":"1","UpdatedBy":"1","Name":"Hello World","ModuleName":"Rpt_Hello_World","ApplicationName":"Asset Inventory","Published":"true","UserId":"1","PostProcessor":""}]'

这是一个字符串。您可以再次使用json.loads。

In [877]: json.loads(data['Data'])
Out[877]: 
[{'ApplicationName': 'Asset Inventory',
  'CreatedBy': '1',
  'Did': 'c055c3d2f3314725b69965e6c55adb5b',
  'InsertedDate': '2017-08-02 7:27:11 AM',
  'ModuleName': 'Rpt_Hello_World',
  'Name': 'Hello World',
  'PostProcessor': '',
  'Published': 'true',
  'UpdatedBy': '1',
  'UpdatedDate': '2017-08-02 9:33:16 AM',
  'UserId': '1'}]
