蟒蛇+ JSON：解析列出

Question

我有点新的（使用Python 2.7）和Python解析JSON数据。有一个服务，我必须发送API调用，并且JSON响应如下所示。 '行'中的项目数量可能会有所不同。我需要做的是只取第二行的“内容”，如果有第二行，并将其放入列表中。本质上，它只是一个“活动确认号码”的列表，没有别的。如果有帮助的话，这个数字总是只有9个数字。任何建议将非常感激。

{"response": 
    {"result": 
     {"Potentials": 
      {"row": 
       [ 
       {"no":"1","FL": 
        {"content":"523836000004148171","val":"POTENTIALID"} 
       }, 
       {"no":"2","FL": 
        {"content":"523836000004924051","val":"POTENTIALID"} 
       }, 
       {"no":"3","FL": 
        [ 
        {"content":"523836000005318448","val":"POTENTIALID"}, 
        {"content":"694275295","val":"Campaign Confirmation Number"} 
        ] 
       }, 
       {"no":"4","FL": 
        [ 
        {"content":"523836000005318662","val":"POTENTIALID"}, 
        {"content":"729545274","val":"Campaign Confirmation Number"} 
        ] 
       }, 
       {"no":"5","FL": 
        [ 
        {"content":"523836000005318663","val":"POTENTIALID"}, 
        {"content":"903187021","val":"Campaign Confirmation Number"} 
        ] 
       }, 
       {"no":"6","FL": 
        {"content":"523836000005322387","val":"POTENTIALID"} 
       }, 
       {"no":"7","FL": 
        [ 
        {"content":"523836000005332558","val":"POTENTIALID"}, 
        {"content":"729416761","val":"Campaign Confirmation Number"} 
        ] 
       } 
       ] 
      } 
     }, 
    "uri":"/crm/private/json/Potentials/getSearchRecords"} 
} 

编辑：输出用于该实施例的一个例子将是：

confs = [694275295，729545274，903187021，729416761]

或

confs = [ '694275295' ，“729545274”，“903187021”，“729416761”]

真的，如果他们存储为字符串或整数

没关系

编辑2：这里是我的代码剪断：

import urllib 
import urllib2 
import datetime 
import json 

key = '[removed]' 

params = { 
    '[removed]' 
    } 

final_URL = 'https://[removed]' 
data = urllib.urlencode(params) 
request = urllib2.Request(final_URL,data) 
response = urllib2.urlopen(request) 
content = response.read() 

j = json.load(content) 

confs = [] 
for no in j["response"]["result"]["Potentials"]["row"]: 
    data = no["FL"] 
    if isinstance(data, list) and len(data) > 1: 
     confs.append(int(data[1]["content"])) 

print confs 

Answer 1

假设j是上面的结构已经被解析到您的JSON对象：

>>> results = [] 
>>> for no in j["response"]["result"]["Potentials"]["row"]: 
...  data = no["FL"] 
...  if isinstance(data, list) and len(data) > 1: 
...   results.append(int(data[1]["content"])) 
... 
>>> results 
[694275295, 729545274, 903187021, 729416761] 

Answer 2

假设 '回应' 持有JSON字符串：

import json 

data = json.loads(response) 
rows = data['response']['result']['Potentials']['rows'] 
output = [] 
for row in rows: 
    contents = row['FL'] 
    if len(contents) > 1: 
     output.append(contents[1]['content']) 

应该这样做。

我终于有一些时间来测试这个“单线”。使用Python的功能特性很有趣：

import json 

#initialize response to your string 
data = json.loads(response) 
rows = data['response']['result']['Potentials']['row'] 
output = [x['FL'][1]['content'] for x in rows if isinstance(x['FL'], list) and len(x['FL']) > 1] 
print output 

['694275295', '729545274', '903187021', '729416761']
