Question

我正在处理我的第一个使用API的项目，但我无法访问数据。我正在研究一个用这个循环调用其数据的例子：

for item in data['objects']:
     print item['name'], item['phone']

这适用于存储为嵌套字典的数据（外部称为对象，内部包含数据）

我遇到的问题是我的数据是使用列表中的dictonaries格式化的

[
{
"key":"2014cama",
"website":"http://www.cvrobotics.org/frc/regional.html",
"official":true,
"end_date":"2014-03-09",
"name":"Central Valley Regional",
"short_name":"Central Valley",
"facebook_eid":null,
"event_district_string":null,
"venue_address":"Madera South High School\n705 W. Pecan Avenue\nMadera, CA 93637\nUSA",      
 "event_district":0,
"location":"Madera, CA, USA",
"event_code":"cama",
"year":2014,
"webcast":[],
"timezone":"America/Los_Angeles",
"alliances":[],
"event_type_string":"Regional",
"start_date":"2014-03-07",
"event_type":0
},'more data...']

所以打电话，

for item in data['objects']:
     print item['name']

无法提取name中存储的值。

非常感谢任何帮助。

修改：完整的数据集I＆＃39; m（http://www.thebluealliance.com/api/v2/team/frc254/2014/events?X-TBA-App-Id=Peter_Hartnett:Scouting:v1）

我正在运行的代码：

import json,urllib2, TBA

team ='frc254'
year = '2014'



Url = 'http://www.thebluealliance.com/api/v2/team/'+team+'/'+year+'/events?X-                        TBA-App-Id=Peter_Hartnett:Scouting:v1'
data = TBA.GetData(Url)

for item in data:
     print item['name']

TBA类只导入数据并将其返回。

EDIT2：这是拉取数据的TBA类，我可以向你保证它与上面链接中的相同

import urllib2,cookielib
content='none'


def GetData(Url):
    site= Url
    hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
       'Accept': '    'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
       'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
       'Accept-Encoding': 'none',
       'Accept-Language': 'en-US,en;q=0.8',
       'Connection': 'keep-alive'}

    req = urllib2.Request(site, headers=hdr)

    try:
        page = urllib2.urlopen(req)
    except urllib2.HTTPError, e:
        print e.fp.read()

    content = page.read()
    return content

如果我理解正确，你的data['objects']现在是列表中的条目，对吗？

所以只需迭代列表，你的逻辑将保持不变

for item in objects:
     print item['name'], item['phone']

正在

objects = [
{
"key":"2014cama",
"website":"http://www.cvrobotics.org/frc/regional.html",
"official":true,
"end_date":"2014-03-09",
"name":"Central Valley Regional",
"short_name":"Central Valley",
"facebook_eid":null,
"event_district_string":null,
"venue_address":"Madera South High School\n705 W. Pecan Avenue\nMadera, CA 93637\nUSA",      
 "event_district":0,
"location":"Madera, CA, USA",
"event_code":"cama",
"year":2014,
"webcast":[],
"timezone":"America/Los_Angeles",
"alliances":[],
"event_type_string":"Regional",
"start_date":"2014-03-07",
"event_type":0
},'more data...']

修改

我现在得到你的问题。您的对象data是string，代表JSONArray。您应该在迭代之前加载，以便能够将其作为真正的list使用，如下所示：

data = GetData(Url)

loaded_array = json.loads(data)

for item in loaded_array:
     print item['name']

在列表中搜索字典
