这可能稍微偏离主题,但由于解决方案是一般表达式问题,我认为在这里解决它可能会很有趣。
我正在尝试访问包含我通常用于分析的数据的网址:
http://stats.nba.com/stats/shotchartdetail?CFID=33&CFPARAMS=2011-12&ContextFilter=&ContextMeasure=FGA&DateFrom=&DateTo=&GameID=&GameSegment=&LastNGames=0&LeagueID=00&Location=&MeasureType=Base&Month=0&OpponentTeamID=0&Outcome=&PaceAdjust=N&PerMode=PerGame&Period=0&PlayerID=0&PlusMinus=N&Position=&Rank=N&RookieYear=&Season=2011-12&SeasonSegment=&SeasonType=Regular+Season&TeamID=0&VsConference=&VsDivision=&mode=Advanced&showDetails=0&showShots=1&showZones=0
正如您在网址中看到的那样,它有许多字段需要填充,而此以前工作过的网址会给我以下错误:
The PlayerPosition property is required.
所以我认为,如果我添加了
,就像URL中的许多其他字段一样&PlayerPosition=0
它会使用每个位置,所以我使用了这个网址:
http://stats.nba.com/stats/shotchartdetail?CFID=33&CFPARAMS=2011-12&ContextFilter=&ContextMeasure=FGA&DateFrom=&DateTo=&GameID=&GameSegment=&LastNGames=0&LeagueID=00&Location=&MeasureType=Base&Month=0&OpponentTeamID=0&Outcome=&PaceAdjust=N&PerMode=PerGame&Period=0&PlayerID=0&PlusMinus=N&Position=&Rank=N&RookieYear=&Season=2011-12&SeasonSegment=&SeasonType=Regular+Season&TeamID=0&VsConference=&VsDivision=&mode=Advanced&showDetails=0&showShots=1&showZones=0&PlayerPosition=0
但它给了我以下错误:
The field PlayerPosition must match the regular expression '^((Guard)|(Center)|(Forward))?$'.
所以我尝试将& PlayerPosition = 0替换为:
&PlayerPosition=&PlayerPosition='^((Guard)|(Center)|(Forward))?$'
&PlayerPosition=&PlayerPosition= ^((Guard)|(Center)|(Forward))?$
&PlayerPosition=&PlayerPosition=((Guard)|(Center)|(Forward))?
&PlayerPosition=&PlayerPosition=((Guard)|(Center)|(Forward))
但没有任何效果,它给了我同样的错误,任何建议?
答案 0 :(得分:1)
玩家位置应与此正则表达式匹配:
'^((Guard)|(Center)|(Forward))?$'
()?
表示括号之间的所有内容都是可选的。因此,(Guard)|(Center)|(Forward)
是可选的。 可以为空白。
表示以下值均有效:
我已经尝试在浏览器中使用它,之后没有任何操作并且有效:

在任何地方添加参数PlayerPosition你的url字符串。但价值只能是“警卫”或“中心”或“前进”。
例如
http://stats.nba.com/stats/shotchartdetail?CFID=33&CFPARAMS=2011-12
&ContextFilter=&ContextMeasure=FGA&DateFrom=&DateTo=&GameID=&GameSegment=
&LastNGames=0&LeagueID=00&Location=&MeasureType=Base&Month=0
&OpponentTeamID=0&Outcome=&PaceAdjust=N&PerMode=PerGame
&Period=0&PlayerID=0&PlusMinus=N&Position=&Rank=N&RookieYear=
&Season=2011-12&SeasonSegment=&SeasonType=Regular+Season&TeamID=0
&VsConference=&VsDivision=&mode=Advanced&showDetails=0&showShots=1
&showZones=0
&PlayerPosition=Guard
