创建一个从网站中抓取文件的python程序
提问于 2015-03-01 12:50:44
到目前为止，这就是我所拥有的
import urllib
Champions=["Aatrox","Ahri","Akali","Alistar","Amumu","Anivia","Annie","Ashe","Azir","Blitzcrank","Brand","Braum","Caitlyn","Cassiopeia","ChoGath","Corki","Darius","Diana","DrMundo","Draven","Elise","Evelynn","Ezreal","Fiddlesticks","Fiora","Fizz","Galio","Gangplank","Garen","Gnar","Gragas","Graves","Hecarim","Heimerdinger","Irelia","Janna","JarvanIV","Jax","Jayce","Jinx","Kalista","Karma","Karthus","Kassadin","Katarina","Kayle","Kennen","KhaZix","KogMaw","LeBlanc","LeeSin","Leona","Lissandra","Lucian","Lulu","Lux","Malphite","Malzahar","Maokai","MasterYi","MissFortune","Mordekaiser","Morgana","Nami","Nasus","Nautilus","Nidalee","Nocturne","Nunu","Olaf","Orianna","Pantheon","Poppy","Quinn","Rammus","RekSai","Renekton","Rengar","Riven","Rumble","Ryze","Sejuani","Shaco","Shen","Shyvana","Singed","Sion","Sivir","Skarner","Sona","Soraka","Swain","Syndra","Talon","Taric","Teemo","Thresh","Tristana","Trundle","Tryndamere","TwistedFate","Twitch","Udyr","Urgot","Varus","Vayne","Veigar","VelKoz","Vi","Viktor","Vladimir","Volibear","Warwick","Wukong","Xerath","XinZhao","Yasuo","Yorick","Zac","Zed","Ziggs","Zilean","Zyra"]
currentCount=0
while currentCount < len(Champions):
urllib.urlretrieve("http://www.lolflavor.com/champions/"+Champions[currentCount]+ "/Recommended/"+Champions[currentCount]+"_lane_scrape.json","C:\Users\Jay\Desktop\LolFlavor\ " +Champions[currentCount]+ "\ "+Champions[currentCount]+ "_lane_scrape.json")
currentCount+=1这个程序所要做的是使用列表和currentCount来获得冠军，然后转到网站，例如"Aatrox“scrape.json，然后下载并存储在这个例子中的文件夹LolFlavor/Aatrox/Aatrox_lane_scplpe.json中。
这个位是阿曲克斯，这取决于冠军。有人能帮我让它开始工作吗？

print(e.r.url)错误来自404 - File or directory not found，因为您的一个调用失败了，因此没有有效的json来解码。令人反感的网址是：
u'http://www.lolflavor.com/champions/Wukong/Recommended/Wukong_lane_scrape.json'如果您在浏览器中尝试，也会给您一个404错误。这是因为您的浏览器中没有可以通过打开Wukong来确认的用户http://www.lolflavor.com/champions/Wukong/。
不需要使用while循环对列表进行索引。只需直接迭代列表项，并使用str.format将变量传递到url。此外，在使用r时，请确保使用原始字符串\'s作为文件路径，因为它们在python中具有特殊意义，用于转义字符，如\n或\r等。在你的道路上会引起麻烦。您还可以使用/或使用\\转义。
