TypeError：尝试从api返回内容时，列表索引必须是整数或片，而不是str

Question

我正在编写一个使用mojang和Hypix API的discord机器人。我试图返回第一行（仅限于游戏类型和模式）

{"success":true,"games":[{"date":1588679703604,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Neon"},{"date":1588679671468,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Skyport"},{"date":1588679612412,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Arena"},{"date":1588679573171,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Spikerock Bay"},{"date":1588679530855,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Backwood"},{"date":1588679503914,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Spikerock Bay"},{"date":1588679453072,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Highset"},

我就是这样做的：

def get_session(name):
    url1 = f"https://api.mojang.com/users/profiles/minecraft/{name}"

    res = requests.get(url1)
    data = res.json()
    if data["id"] is None:
        return None
    returnUuid = (data["id"])

    url2 = f"https://api.hypixel.net/recentGames?key={API_KEY}&uuid=" + returnUuid

    res = requests.get(url2)
    data = res.json()
    if data["games"] is None:
        return None
    returnGametype = (data["games"]["gameType"])
    returnGamemode = (data["games"]["mode"])

但是它给了我一个错误，Command Raised an exception: TypeError: list indices must be integers or slices, not str.

我认为这与多行有关。不过我不知道该怎么办

Answer 1

正如您所注意到的，它与多行有关

{"success":true,"games":[
{"date":1588679703604,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Neon"},
{"date":1588679671468,"gameType":"DUELS","mode":"CLASSIC_DUEL","map":"Skyport"}...]

端点返回json，即对于键'games'具有数组/多个值。 因此，如果要获取数组中第一个元素的'gameType'和'mode'值，必须编写：

 returnGametype = (data["games"][0]["gameType"])
 returnGamemode = (data["games"][0]["mode"])

Answer 2

词典嵌套在一个列表中。这就是索引错误的原因（因为列表索引不能是字符串）。如果要使用“游戏”列表中的第一个结果，请使用第一个索引（0）：

game_type = data["games"][0]["gameType"]
game_mode = data["games"][0]["mode"]
