使用json项键入错误

Question

我通过模仿XHR请求返回包含网站词典的json列表。代码如下：

import requests

url = 'http://www.whoscored.com/stageplayerstatfeed/-1/Overall'
params = {
'field': '0',
'isAscending': 'false',
'isMoreThanAvgApps': 'true',
'isOverall': 'false',
'numberOfPlayersToPick': '20',
'orderBy': 'Rating',
'page': '1',
'stageId': '9155',
'teamId': '-1'
}

headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.125 Safari/537.36',
           'X-Requested-With': 'XMLHttpRequest',
           'Host': 'www.whoscored.com',
           'Referer': 'http://www.whoscored.com/'}

responser = requests.get(url, params=params, headers=headers)
playerdata = responser.json()


for player in playerdata:


    print ("{TeamId},{PlayerId},{GameStarted},{SubOn},{SubOff},{Yellow},{SecondYellow},{Red},{Goals},{Assists},{TotalPasses},{AccuratePasses},"
"{AerialWon},{AerialLost},{Rating},{ManOfTheMatch},{TotalTackles},{Interceptions},{Fouls},{OffsidesWon},{TotalClearances},{WasDribbled},"
"{TotalShots},{ShotsOnTarget},{ShotsBlocked},{OwnGoals},{KeyPasses},{Dribbles},{WasFouled},{Offsides},{Dispossesed},{Turnovers},"
"{TotalCrosses},{AccurateCrosses},{TotalLongBalls},{AccurateLongBalls},{TotalThroughBalls},{AccurateThroughBalls},{RegionName},"
"{RegionCode},{RegionId},{TournamentId},{TournamentName},{SeasonId},{StageId},{TeamRegionCode},{TeamName},{TeamIsNational},{IsOpta},"
"{TeamRegionId},{TeamRegionName},{TournamentShortName},{SeasonName},{PlayedPositionsRaw},{PositionText},{PositionShort},{PositionLong},"
"{Name},{Height},{Weight},{FirstName},{LastName},{KnownName},{WSName},{DateOfBirth},{Age},{Ranking}".decode('cp1252').format(**player))

我正在尝试打印此请求中返回的字典值元素，但是我收到以下错误：

exceptions.TypeError: format() argument after ** must be a mapping, not list

我之前使用的代码格式与此类似，没有问题，我不确定如何修复此错误。有人可以帮忙吗？

Answer 1

响应在列表中包含两个元素，只有第二个元素是一个播放器列表：

相应地调整循环：

playerdata = responser.json()

for player in playerdata[1]:

在字符串文字中使用.decode()没有意义;只需在字符串上使用u"..."前缀即可使其成为unicode对象。

您的print()语句中似乎需要67个键，但播放器对象中只有57个键：

>>> len(player.keys())
57

你需要在那里调整你的期望。
