Question

我正在使用Python解析JSON feed。 JSON提要每30秒左右更新一次。我需要从对战游戏中提取信息，但是对战游戏ID的唯一ID节点在每个游戏上都会发生变化。

我已经可以通过对uniqueID进行硬编码来解析所需的数据，但是当新游戏进入提要时，我将不知道uniqueID是什么，因此代码将失败。

以下代码确实有效，但是我需要一种查找或通配符（我知道直接在Python中无法实现）唯一ID 1572805的方法。

下面是JSON的摘录，您可以在其中看到每个游戏的数据都有一个新的uniqueID：-

import urllib2, cookielib, json, io
import datetime

url = "JSON URL - REMOVED"
sportsFeed = r"c:\feeds\results.txt"
try:    
    scorepro = urllib2.urlopen(url)
    wjson = scorepro.read()
    wjdata = json.loads(wjson)
    today = str(datetime.datetime.today().strftime('%Y-%m-%d'))
    playerone = wjdata['list']['Sport']['2']['Matchday'][today]['Match']['1572805']['Home']['name']
    print "playerone = " + playerone

except:
    print "error"

如何重新创建代码，以便查找所有uniqueID，然后能够使用这些预定义的uniqueID解析JSON？

谢谢。

Answer 1

使用以下代码来解析JSON中的ID，每次将键＃递增1，例如：-

id = wjdata['list']['Sport']['2']['Matchday'][today]['Match'].keys()[0]
playerone = wjdata['list']['Sport']['2']['Matchday'][today]['Match'][id]['Home']['name']
id = wjdata['list']['Sport']['2']['Matchday'][today]['Match'].keys()[1]
playerone = wjdata['list']['Sport']['2']['Matchday'][today]['Match'][id]['Home']['name']

Answer 2

使用IsCompleted = 1字典并遍历所有匹配项。

Match

使用Python引用的具有唯一ID的JSON feed
