使用openweather获取天气（python）

可恶，琢磨了好久，今天终于给他干出来了！

博客

代码

官方示例

这个是获取地理信息的……

http://api.openweathermap.org/geo/1.0/direct?q={city name},{state code},{country code}&limit={limit}&appid={API key}

q 必填 城市名称、州代码（仅适用于美国）和国家/地区代码，用逗号分隔。请使用 ISO 3166 个国家/地区代码。

appid 必填 您唯一的 API 密钥（您始终可以在帐户页面上的“API 密钥”选项卡下找到它）

limit 自选 API 响应中的位置数（API 中最多可以返回 5 个结果 响应）

代码

依赖的第三方库

pip install requests
pip install tkinter

至于剩下的，看运气吧，有的话不管。

Python代码

import requests
import json
import datetime
import time
import tkinter as tk

只想学怎么调用的看这里

如何调用数据参考上面的“字典内信息”

language = 'zh_cn'  # 简体中文  &lang={language}
city_name = get_city.get()  # q={city_name}
# limit = 5  # &limit={limit}
API_key = get_api.get()  # &appid={API_key}
# api_name = 'api'  # 好像没什么用
url = f'http://api.openweathermap.org/data/2.5/weather?q={city_name}&units=metric&appid={API_key}&lang={language}'

target = requests.get(url)
content = target.json()
s = json.dumps(content, ensure_ascii=False, indent=2)
data = json.loads(s)

# 气象数据
city = data["name"]
weather = data["weather"][0]["main"]  # Clouds
weather_description = data["weather"][0]["description"]  # 多云
temp = data['main']['temp']  # ℃
pressure = data['main']['pressure']  # Pa
humidity = data['main']['humidity']  # %
visibility = data['visibility']  # m
sunrise = trans_time(data['sys']['sunrise'])
sunset = trans_time(data['sys']['sunset'])
x = {'city': city, 'weather': weather, 'weather_description': weather_description, 'temp': temp,'pressure': pressure, 'humidity': humidity, 'visibility': visibility, 'sunrise': sunrise, 'sunset': sunset}

你可以分别print一下看看效果或者分步学习
