好的,我正在尝试在跟踪器中获取人员和时间戳,但我一直收到此错误:

list indices must be integer, not str

这是获取该错误的代码:

elif used_prefix and cmd == "tracker" and self.getAccess(user) >= 1:
   try:
     if len(args) == 0:
        name = user.name.lower()
    elif len(args) > 0:
        name = args.lower()
    f = urlreq.urlopen("http://chtracker.info/index.py?output=json&x=page&y={}".format(name))
    data = json.loads(f.readall().decode("utf-8"))['viewer'][:10]
    t = "{}, the last 10 people who visited {}'s profile are: ".format(name.title(), name.title())
    viewers = [(item['viewer'], item['timestamp']) for item in data]
    for l in viewers:
       viewer, timest = l
       t += "{} about {} ago".format(viewer, stamp.getTimeStamp((timest)))
   room.message(t, True)
except:
   print(traceback.format_exc())
   room.message((str(sys.exc_info()[1])))

错误发生在这一行:

data = json.loads(f.readall().decode('utf-8'))['viewer'][:10]

在网址中,dictionarys具有相同的标签“viewer”和“timestamp”,例如:

http://chtracker.info/index.py?output=json&x=page&y=mechabot

答案 0 :(得分:2)

json.loads(...)正在返回list,所以当你这样做时:

json.loads(...)['viewer']

您正尝试访问索引为list且无效的'viewer'

您可以通过打印json.loads(f.readall().decode("utf-8"))来实现这一点,这样您就可以找到正确的方法来访问它的价值。
