为什么我收到“TypeError：字符串索引必须是整数”？

Question

import nextcord
from nextcord.ext import commands
from config import TOKEN, API_KEY
import aiohttp

bot = commands.Bot(command_prefix = "!", intents = nextcord.Intents.all())

@bot.event
async def on_ready():
    print("Bot has connected to Discord")

@bot.command()
async def weather(ctx: commands.Context, *, city):
    url = "http://api.weatherapi.com/v1/current.json"
    params = {
        "key": API_KEY,
        "q": city
    }

    async with aiohttp.ClientSession() as session:
        async with session.get(url, params=params) as responses:
            data = await responses.json()
            
            print(data)
            location = data["location"]["name"]["localtime"]

我不断在“location = data["location"]["name"]["localtime"]"这一行收到类型错误

TypeError: string indices must be integers, not 'str'

在天气 API 中，信息存储在嵌套字典中。我通过使用

location = data["outer_key"]["inner_key"]

访问这些值

我传递的命令是

!weather "city_name"

我做错了什么？

我不确定，但由于你的数据变量不能是列表，如果你想使用位置变量，你必须将其转换为字典：location = data["location"]["name"]["localtime ”]

正确类型： 数据 = {位置: {"name": {"localtime": "2024-04-15 12:00"}}}
