最近实现一个小工具，其中涵盖了天气的功能，把自己的实现过程以及如何使用记录如下。

Gittee：https://gitee.com/wanliwumai/weather.git

♥特别注意：不要频繁调用该API，避免增加服务器的负载

一、安装所需模块

import os
import re
import json
import requests
import argparse
from datetime import datetime

二、代码介绍

1、根据城市名称获取城市ID

已经将大部分城市与城市对应的代码存放于script/weather_city.json，首先根据输入的名字获取ID

def get_id(city):
    """
    根据城市名获取id
    :param city: city_names
    :return: city_id
    """
    root_path = os.path.split(os.path.realpath(__file__))[0]
    with open(os.path.join(root_path, 'weather_city.json'), 'r', encoding='utf8') as fp:
        city_dict = json.load(fp)
    if city in city_dict:
        return city_dict[city]
    else:
        print('Can not find the city: {}'.format(city))
        return city_dict['北京']

2、调用API返回当前城市的天气

调用API返回天气的字典

def get_weather(city):
    """
    调用API返回当前天气
    :param city: city_name
    :return:
    """
    city_id = get_id(city)
    weather_web = 'http://wthrcdn.etouch.cn/weather_mini?citykey='
    request = requests.get('{}{}'.format(weather_web, city_id))
    weatherinfo = request.json()
    return weatherinfo

3、定制个性化输出

该部分额外加入时间判断，在早上7:00之前不进行输出，在晚上20:00之后加入第二天的天气情况。可进行个性化定制

def info_edit(info):
    """
    规范化输出天气信息
    :param info: 天气的字典
    :return:
    """
    flag = get_flag()
    if flag == 0:
        return None
    today = datetime.today().strftime("%Y-%m-%d")
    city = info['data']['city']
    low = info['data']['forecast'][0]['low']
    high = info['data']['forecast'][0]['high']
    fengxiang = info['data']['forecast'][0]['fengxiang']
    fengli = re.findall('<!\[CDATA\[(\d+级)\]\]>', info['data']['forecast'][0]['fengli'])[0]
    wendu = info['data']['wendu']
    string = info['data']['ganmao']
    line = "今天是: {}\n{}: {}~{}\n{}\t{}\n实时温度: {} ℃\n{}\n".format(
        today, city, low, high, fengxiang, fengli, wendu, string)
    if flag == 1:
        low_t = info['data']['forecast'][1]['low']
        high_t = info['data']['forecast'][1]['high']
        fengxiang_t = info['data']['forecast'][1]['fengxiang']
        fengli_t = re.findall('<!\[CDATA\[(\d+级)\]\]>', info['data']['forecast'][1]['fengli'])[0]
        line += "明天: {}~{}\n{}\t{}\n".format(low_t, high_t, fengxiang_t, fengli_t)
    return line

三、使用方法

直接下载代码安装所需模块后即可使用

git clone https://gitee.com/wanliwumai/weather.git
python weather/script/weather.py -c "北京"

可根据自己的需求设计个性化的输出。
