discord.py中如何从API获取JSON数据并以embed形式发送天气查询结果

修正方案 #

你的代码主要存在三类错误：

1. Python字典取值方式错误：调用response.json()后得到的是嵌套字典，只能通过dict[key]的方式取值，不能使用.xxx()的方法调用写法
2. 字段归属与拼写错误：比如wind_kph属于current字段而非location，风向字段应为wind_dir而非你写的vwind_dir
3. Embed组装时存在语法错误，部分字段的value、最终发送的embed参数未补全

修正后的完整可运行代码如下：

import discord
from discord.ext import commands
import requests
# 高并发场景建议替换为异步的aiohttp库，避免阻塞机器人事件循环

# 替换为你自己的API接口地址和请求头
url = "你的天气API地址"
headers = {"你的API鉴权头字段": "对应值"}

@commands.command()
async def weather(self, ctx, *, location_name):
    # 增加异常捕获，避免请求失败、地点不存在导致机器人直接报错
    try:
        querystring = {"q": location_name}
        response = requests.get(url, headers=headers, params=querystring)
        response.raise_for_status()
        weather_data = response.json()

        # 按JSON层级正确提取字段
        location = weather_data["location"]["name"]
        region = weather_data["location"]["region"]
        country = weather_data["location"]["country"]
        temperature = weather_data["current"]["temp_c"]
        condition = weather_data["current"]["condition"]["text"]
        wind_speed = weather_data["current"]["wind_kph"]
        wind_degree = weather_data["current"]["wind_degree"]
        wind_dir = weather_data["current"]["wind_dir"]
        humidity = weather_data["current"]["humidity"]
        feelslike = weather_data["current"]["feelslike_c"]
        condition_icon = weather_data["current"]["condition"]["icon"]

        # 组装Embed
        weather_embed = discord.Embed(
            title="天气信息",
            description=f"{location} 的实时天气情况",
            color=discord.Colour.random()
        )
        # 大部分天气API返回的图标地址不带https前缀，此处做适配
        icon_url = f"https:{condition_icon}" if not condition_icon.startswith("http") else condition_icon
        weather_embed.set_thumbnail(url=icon_url)
        weather_embed.add_field(name="地点", value=location, inline=True)
        weather_embed.add_field(name="行政区", value=region, inline=True)
        weather_embed.add_field(name="国家", value=country, inline=True)
        weather_embed.add_field(name="温度", value=f"{temperature} °C", inline=True)
        weather_embed.add_field(name="天气状况", value=condition, inline=True)
        weather_embed.add_field(name="体感温度", value=f"{feelslike} °C", inline=True)
        weather_embed.add_field(name="风速", value=f"{wind_speed} 公里/小时", inline=True)
        weather_embed.add_field(name="风向角度", value=f"{wind_degree}°", inline=True)
        weather_embed.add_field(name="风向", value=wind_dir, inline=True)
        weather_embed.add_field(name="湿度", value=f"{humidity}%", inline=True)

        await ctx.send(embed=weather_embed)
    except Exception as e:
        await ctx.send(f"查询失败，请检查输入的地名是否正确，错误信息：{str(e)}")

补充说明 #

• 参数写法*, location_name可以支持带空格的地名查询，比如输入!weather New York也能正常识别
• 如果你的API返回的图标已经是完整的http/https地址，可以删掉图标地址的前缀适配逻辑
