先看下效果圖:python
用到的模塊:mysql
要實現上面的示例,首先是有兩大塊地方sql
而獲取天氣信息又包括幾個小的須要注意的地方數據庫
獲取天氣信息json
假如咱們給多我的發送天氣狀況,這幾我的來自不一樣的城市,那麼咱們不可能每次都要輸入城市名,而後查找城市碼,而後再訪問接口,獲取天氣狀況,這樣會很是的麻煩,因此咱們須要考慮將城市名跟城市碼一一對應起來,說到一一對應,首先想到的數據結構即是字典,因此咱們能夠將這些信息存入一個字典裏,而後持久化到一個文件中,這樣便方便不少api
首先咱們獲取最新的 city 表,這個表是一個 list 類型,大致格式以下:微信
[ { "id": 1, "pid": 0, "city_code": "101010100", "city_name": "北京", "post_code": "100000", "area_code": "010", "ctime": "2019-07-11 17:30:06" }, { "id": 2, "pid": 0, "city_code": "", "city_name": "安徽", "post_code": null, "area_code": null, "ctime": null } ]
咱們就簡單的粘貼複製,放到一個空的列表中,以下所示,將全部的城市信息放到列表 citycode 中數據結構
citycode = [ { "id": 1, "pid": 0, "city_code": "101010100", "city_name": "北京", "post_code": "100000", "area_code": "010", "ctime": "2019-07-11 17:30:06" }, ... ... ... ... ... ... { "id": 2, "pid": 0, "city_code": "None", "city_name": "安徽", "post_code": "null", "area_code": "null", "ctime": "null" } ] cityinfo = {} #將城市名和城市代碼寫入json文件中 with open('city_for_code.json','w',encoding='utf-8') as f: for i in citycode: name = i["city_name"] code = i["city_code"] cityinfo[name] = code f.write(str(cityinfo)) #測試是否能讀取 with open('city_for_code.json','r+',encoding='utf-8') as file: data_dst = file.readlines() d = eval(data_dst[0])
而後就是一頓處理,只把咱們所需的 city_name 和 city_code 這倆字段取出便可,隨後寫入文件中。若是讀取的話就按照上面方法去讀取,須要注意的是,使用 open()方法讀取文件,獲得的內容是一個列表,咱們須要經過 eval()方法轉化成 dict 類型。app
這是把 city_name 和 city_code 放到一個文件中的方法,另外咱們也能夠放到數據庫中,這裏以 MySQL 爲例,安裝 PyMySQL 模塊工具
import pymysql db_parames = { 'host': 'localhost', 'user': 'root', 'password': '123456', 'database': 'city_code_info' } #鏈接數據庫 conn = pymysql.connect(**db_parames) #建立遊標對象,增刪改查都在遊標上進行 cursor = conn.cursor() #表存在,就刪除 cursor.execute("DROP TABLE IF EXISTS city_code") #建表語句 create_table_sql = """CREATE TABLE `city_code` ( `city_name` varchar(20) DEFAULT NULL, `city_code` varchar(25) DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4; """ #建表 cursor.execute(create_table_sql) #插入數據 with open('city_for_code.json','r+',encoding='utf-8') as f: origin_data = f.readlines() current_data = eval(origin_data[0]) #讀取的內容是一個列表,且只包含一個元素 #print(current_data.get('北京','Not Exists.')) for name, code in current_data.items(): sql = """INSERT INTO city_code(city_name, city_code) VALUES ('%s', '%s')""" % (name, code) try: cursor.execute(sql) except: conn.rollback() conn.commit() conn.close()
執行這個 python 程序就能夠將文件中的城市名跟城市碼存到庫中,固然咱們也能夠直接獲取到城市名和城市碼,而後跳過文件持久化這一步,直接把這兩個字段取出存進去,可是考慮着代碼要多練多寫,就畫蛇添足了一下。
下面是輸入城市名就能獲得城市碼的代碼塊:
import pymysql def get_city_code(city_name): db_parames = { 'host': 'localhost', 'user': 'root', 'password': '123456', 'database': 'city_code_info' } #鏈接數據庫 conn = pymysql.connect(**db_parames) #建立遊標對象,增刪改查都在遊標上進行 cursor = conn.cursor() #建立查詢語句 select_sql = "SELECT * FROM city_code where city_name='%s'"%(city_name) try: cursor.execute(select_sql) result = cursor.fetchall() for row in result: city_code = row[1] return city_code except: return "Error: unable fetch data!"
而後是根據輸入的城市碼來獲取天氣狀況:
import requests def get_weather(city_name,get_date_time=3): city_code = get_city_code(city_name) url = 'http://t.weather.sojson.com/api/weather/city/%s'%(city_code) header = { 'user-agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36' } response = requests.get(url,header) response.encoding = 'utf-8' weather = response.json() day = {1: '明天', 2: '後天', 3: '大後天'} weather_lst = [] for num in range(get_date_time): City = weather["cityInfo"]["city"] Weatherganmao = weather["data"]["ganmao"] Weatherquality = weather["data"]["quality"] Weathershidu = weather["data"]["shidu"] Weatherwendu = weather["data"]["wendu"] Weatherpm25 = str(weather["data"]["pm25"]) Weatherpm10 = str(weather["data"]["pm10"]) Dateymd = weather["data"]["forecast"][num]["ymd"] Dateweek = weather["data"]["forecast"][num]["week"] Sunrise = weather["data"]["forecast"][num]["sunrise"] Sunset = weather["data"]["forecast"][num]["sunset"] Windfx = weather["data"]["forecast"][num]["fx"] Windf1 = weather["data"]["forecast"][num]["fl"] Weathertype = weather["data"]["forecast"][num]["type"] Weathernotice = weather["data"]["forecast"][num]["notice"] Weatherhigh = weather["data"]["forecast"][num]["high"] Weatherlow = weather["data"]["forecast"][num]["low"] if num == 0: result = '今日天氣預報' + '\n' \ + '日期: ' + Dateymd + ' ' + Dateweek + ' ' + City + '\n' \ + '天氣: ' + Weathertype + ' ' + Windfx + ' ' + Windf1 + ' ' + Weathernotice + '\n' \ + '當前溫度: ' + Weatherwendu + '℃' + '\n' \ + '空氣溼度: ' + Weathershidu + '\n' \ + '溫度範圍: ' + Weatherlow + '' + '~' + '' + Weatherhigh + '\n' \ + '污染指數: ' + 'PM2.5: ' + Weatherpm25 + ' ' + 'PM10: ' + Weatherpm10 + '\n' \ + '空氣質量: ' + Weatherquality + '\n' \ + '日出時間: ' + Sunrise + '\n' \ + '日落時間: ' + Sunset + '\n' \ + '舒適提示: ' + Weatherganmao else: which_day = day.get(num,'超出範圍') result = '\n' + which_day + ' ' + '天氣預報' + '\n' \ + '日期: ' + Dateymd + ' ' + Dateweek + ' ' + City + '\n' \ + '天氣: ' + Weathertype + ' ' + Windfx + ' ' + Windf1 + ' ' + Weathernotice + '\n' \ + '溫度範圍: ' + Weatherlow + '' + '~' + '' + Weatherhigh + '\n' \ + '日出時間: ' + Sunrise + '\n' \ + '日落時間: ' + Sunset + '\n' \ + '舒適提示: ' + Weatherganmao weather_lst.append(result) weather_str = '' #由於默認要輸出三天的天氣狀況,因此咱們須要建立一個空字符串,而後每迭代一次,就將天氣狀況拼接到空字符串中。 for msg in weather_lst: weather_str += msg + '\n' return weather_str
下面是發送微信消息
from wxpy import * def send_wx(city_name, who): bot = Bot(cache_path=True) #bot = Bot(console_qr=2, cache_path='botoo.pkl') my_friend = bot.friends().search(who)[0] msg = get_weather(city_name) try: my_friend.send(msg) except: my_friend = bot.friends().search('fei')[0] my_friend.send(u"發送失敗")
而後咱們還須要寫一個定時器,每隔一段時間便要發送一次
from threading import Timer def auto_send(): city_name = '設置要發送的城市' friend_list = ['要發送的人'] for who in friend_list: send_wx(city_name,who) global timer timer = Timer(1,auto_send) timer.start()
最後執行程序
if __name__ == '__main__': timer = Timer(1,auto_send) timer.start()
