如何在JSON中循环条目？

Question

我想循环遍历JSON文件的内容并将其打印到控制台.

我想我确实把一些东西与名单搞混了.

这就是我试图获得所有team_name元素的原因

from urllib2 import urlopen
import json

url = 'http://openligadb-json.heroku.com/api/teams_by_league_saison?league_saison=2012&league_shortcut=bl1'
response = urlopen(url)
json_obj = json.load(response)

for i in json_obj['team']:
    print i

这是我的JSON(简化:)

{
    "team": [
        {
            "team_icon_url": "http://www.openligadb.de/images/teamicons/Hamburger_SV.gif",
            "team_id": "100",
            "team_name": "Hamburger SV"
        },
        {
            "team_icon_url": "http://www.openligadb.de/images/teamicons/FC_Schalke_04.gif",
            "team_id": "9",
            "team_name": "FC Schalke 04"
        }
    ]
}

(可在此处找到完整的JSON输出:链接)

当然我得到一个错误,我应该在[]中使用整数输入,而不是字符串,但我不知道如何做到这一点.

for i in json_obj['team']:
TypeError: string indices must be integers, not str

这是response:

http://openligadb-json.heroku.com/api/teams_by_league_saison?league_saison=2012&league_shortcut=bl1
<addinfourl at 139755086292608 whose fp = <socket._fileobject object at 0x7f1b446d33d0>>

我弄错了什么？

Answer 1

实际上,要查询team_name,只需将其添加到括号中的最后一行.除此之外,它似乎在命令行上使用Python 2.7.3.

from urllib2 import urlopen
import json

url = 'http://openligadb-json.heroku.com/api/teams_by_league_saison?league_saison=2012&league_shortcut=bl1'
response = urlopen(url)
json_obj = json.load(response)

for i in json_obj['team']:
    print i['team_name']

Answer 2

试试这个 :

import urllib, urllib2, json
url = 'http://openligadb-json.heroku.com/api/teams_by_league_saison?league_saison=2012&league_shortcut=bl1'
request = urllib2.Request(url)
request.add_header('User-Agent','Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)')
request.add_header('Content-Type','application/json')
response = urllib2.urlopen(request)
json_object = json.load(response)
#print json_object['results']
if json_object['team'] == []:
    print 'No Data!'
else:
    for rows in json_object['team']:
        print 'Team ID:' + rows['team_id']
        print 'Team Name:' + rows['team_name']
        print 'Team URL:' + rows['team_icon_url']
