如何从Riot Games API中提取数据？

Posted 2021-04-16

我还是初学者，刚开始使用Python。我尝试通过JSON获得Riot Games（仅EUW）API的玩家等级和等级，但我得到一个例外：

print (responseJSON2[ID][0]['tier'])

TypeError: list indices must be integers or slices, not str

我不知道我要改变什么，也许有人可以帮助我:)代码：

import requests

def requestSummonerData(summonerName, APIKey):

    URL = "https://euw1.api.riotgames.com/lol/summoner/v3/summoners/by-name/" + summonerName + "?api_key=" + APIKey
    print (URL)
    response = requests.get(URL)
    return response.json()

def requestRankedData(ID, APIKey):
    URL= "https://euw1.api.riotgames.com/lol/league/v3/positions/by-summoner/"+ID+"?api_key="+APIKey
    print (URL)
    response = requests.get(URL)
    return response.json()


def main():

    summonerName = (str)(input('Type your Summoner Name here: '))
    APIKey = (str)(input('Copy and paste your API Key here: '))
    responseJSON  = requestSummonerData(summonerName, APIKey)

    print(responseJSON)
    ID = responseJSON ['id']
    ID = str(ID)
    print (ID)
    responseJSON2 = requestRankedData(ID, APIKey)
    print (responseJSON2[ID][0]['tier'])
    print (responseJSON2[ID][0]['entries'][0]['rank'])
    print (responseJSON2[ID][0]['entries'][0]['leaguePoints'])


if __name__ == "__main__":
    main()

答案

responseJSON2是一个list。列表包含索引（0,1,2，...）。

您需要为列表使用int：

ID = str(ID)

是错的，你需要有一个int！

尝试

ID = int(ID)

你可以转换回字符串：

def requestRankedData(ID, APIKey):
    URL= "https://euw1.api.riotgames.com/lol/league/v3/positions/by-summoner/"+str(ID)+"?api_key="+APIKey
    print (URL)
    response = requests.get(URL)
    return response.json()

您需要在响应中找到与您的ID匹配的索引：

responseJSON2 = requestRankedData(ID, APIKey)
ID_idx = responseJSON2.index(str(ID))
print (responseJSON2[ID_idx][0]['tier'])
print (responseJSON2[ID_idx][0]['entries'][0]['rank'])
print (responseJSON2[ID_idx][0]['entries'][0]['leaguePoints'])
