创建一个python程序，从websi中提取文件

Question

这就是我目前所拥有的

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

程序要做的是使用list和currentCount来获得冠军，然后它进入网站，例如“Aatrox”http://www.lolflavor.com/champions/Aatrox/Recommended/Aatrox_lane_scrape.json，然后它下载文件并将其存储在lolvalivor/Aatrox/Aatrox\u lane文件夹中_scrape.json文件在这种情况下。你知道吗

Aatrox的位根据冠军而变化。 有人能帮我把它修好吗？你知道吗

编辑：当前代码值错误：

Answer 1

import  requests

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"]

for champ in Champions:
    r = requests.get("http://www.lolflavor.com/champions/{}/Recommended/{}_lane_scrape.json".format(champ,champ))
    print(r.json())

如果要将每个文件保存到一个文件中。dumpjson。你知道吗

import json
import simplejson 

for champ in Champions:
    with open(r"C:\Users\Jay\Desktop\LolFlavor\{}_lane_scrape.json".format(champ),"w") as f:
        try:
            r = requests.get("http://www.lolflavor.com/champions/{}/Recommended/{}_lane_scrape.json".format(champ, champ))
            json.dump(r.json(),f)
        except simplejson.scanner.JSONDecodeError as e:
            print(e.r.url)

错误来自404 - File or directory not found，因为其中一个调用失败，所以没有有效的json可解码。 有问题的url是：

u'http://www.lolflavor.com/champions/Wukong/Recommended/Wukong_lane_scrape.json'

如果在浏览器中尝试，也会出现404错误。这是因为没有用户Wukong，这可以通过在浏览器中打开http://www.lolflavor.com/champions/Wukong/来确认

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格式将变量传递到url。在使用\'s时，还要确保使用原始字符串r作为文件路径，因为它们在python中有特殊的含义，用于转义字符\n或\r等。。在你的道路上会引起问题。也可以使用/或使用\\转义。你知道吗
