基于ajax的网站的PHP爬虫?(php crawler for ajax based websites?)
也许这听起来很幼稚,但是有没有什么东西甚至可以远程接近基于ajax的网站的php爬虫?
Maybe this is gonna sound naive and all, but is there something even remotely close to a php crawler for ajax based websites?

你的代码奇怪的主要原因是你所有的西装词典(
S
,H
,D
和C
)都引用了同一个字典。 如果您希望它们指向不同的引用(例如S, H, D, C = {}, {}, {}, {}
)S, H, D, C = {}, {}, {}, {}
则需要单独初始化它们。话虽如此,
eval
(几乎)绝不是解决方案。 在你的情况下,我会做类似的事情:keys = list('23456789TJQKA') values = range (13) suitDict = {} for key,value in zip(keys, values): suitDict[key] = value dealList = 'AQJT5.KQ.8.KQT95 3.A765.QT743.843 974.T93.J92.AJ62 K862.J842.AK65.7'.split() players = list('NESW') suits = {"S": {}, "H": {}, "D": {}, "C": {}} playerHand = {} for player,hand in zip(players,dealList): playerHand[player] = hand print player,hand for suit,cards in zip(suits,playerHand[player].split('.')): print "SC:",suit,cards for card in cards: suits[suit][suitDict[card]] = player print "card",card,"Suit",suit,"X",suits[suit],"card",suitDict[card],"player",player
话虽如此,我认为你的案件过于复杂......
Your code oddity is mainly caused by the fact that all your suit dictionaries (
S
,H
,D
andC
) are referencing the same dictionary. You need to initialize them separately if you want them to point to a different reference (e.g.S, H, D, C = {}, {}, {}, {}
).That being said,
eval
is (almost) never a solution. In your case, I'd do something like:keys = list('23456789TJQKA') values = range (13) suitDict = {} for key,value in zip(keys, values): suitDict[key] = value dealList = 'AQJT5.KQ.8.KQT95 3.A765.QT743.843 974.T93.J92.AJ62 K862.J842.AK65.7'.split() players = list('NESW') suits = {"S": {}, "H": {}, "D": {}, "C": {}} playerHand = {} for player,hand in zip(players,dealList): playerHand[player] = hand print player,hand for suit,cards in zip(suits,playerHand[player].split('.')): print "SC:",suit,cards for card in cards: suits[suit][suitDict[card]] = player print "card",card,"Suit",suit,"X",suits[suit],"card",suitDict[card],"player",player
That being said, I think you're over-complicating your case...
