前言

之前写过一个程序，获取7天内天气预报的，但是仅仅是获取到七天内某个城市的天气预报，没有想过具体的实际案例。
随后看了一些其他的模块，感觉跟微信结合起来的应用场景还是挺实用的，然后就把它折腾出来了。

基本功能

基本功能其实也是核心功能，主要就是获取指定城市的天气情况
本次利用的是百度的一个api网址：
http://api.map.baidu.com/telematics/v3/weather?location=%s&output=json&ak=TueGDhCvwI6fOrQnLM0qmXxY9N0OkOiQ&callback=?
其中location这个参数后面跟的就是城市，调用这个api可以获取到当前城市天气情况，比如北京当前天气：

得到的是json数据，经过简单的处理就可以得到能看的数据

核心程序如下：

#发送天气情况
def send_weather(location):

    path ='http://api.map.baidu.com/telematics/v3/weather?location=%s&output=json&ak=TueGDhCvwI6fOrQnLM0qmXxY9N0OkOiQ&callback=?'
    url = path % location
    print(url)
    response = requests.get(url)
    result = response.json()

    #如果城市错误就按照海淀发送天气
    if result['error'] !=0:
        location ='海淀'
        url = path % location
        print(url)
        response = requests.get(url)
        result = response.json()

    str0 = ('    这是今天的天气预报！\n')
    results = result['results']

    # 取出数据字典

    data1 = results[0]

    # 取出城市
    city = data1['currentCity']
    str1 ='    当前地区: %s\n' % city

    # 取出pm2.5值
    pm25 = data1['pm25']
    str2 ='    Pm值    : %s\n' % pm25

    # 将字符串转换为整数 否则无法比较大小
    if pm25 =='':
        pm25 =0
    pm25 =int(pm25)

    # 通过pm2.5的值大小判断污染指数
    if 0 <= pm25 <35:
        pollution ='优'
    elif 35 <= pm25 <75:
        pollution ='良'
    elif 75 <= pm25 <115:
        pollution ='轻度污染'
    elif 115 <= pm25 <150:
        pollution ='中度污染'
    elif 150 <= pm25 <250:
        pollution ='重度污染'
    elif pm25 >=250:
        pollution ='严重污染'
    str3 ='    污染指数: %s\n' % pollution

    result1 = results[0]

    weather_data = result1['weather_data']
    data = weather_data[0]
    #实时温度
    temperature_now = data['date']
    str4 ='    当前温度: %s\n' % temperature_now

    #风向
    wind = data['wind']
    str5 ='    风向    : %s\n' % wind

    #天气和温度
    weather = data['weather']
    str6 ='    天气    : %s\n' % weather
    str7 ='    温度    : %s\n' % data['temperature']

    #其他提示
    message = data1['index']
    str8 ='    穿衣    : %s\n' % message[0]['des']
    str9 ='    温馨提示: %s\n' % message[2]['des']
    str10 ='    运动    : %s\n' % message[3]['des']
    str11 ='    紫外线 : %s\n' % message[4]['des']

    #未来天气情况
    weather_data=result1['weather_data']
    future1='\t%s \n\t\t\t\t温度：%s\n\t\t\t\t天气：%s\n\t\t\t\t风向：%s\n ' % (weather_data[1]['date'],weather_data[1]['temperature'],weather_data[1]['weather'] ,weather_data[1]['wind'])
    future2='\t%s \n\t\t\t\t温度：%s\n\t\t\t\t天气：%s\n\t\t\t\t风向：%s\n ' % (weather_data[2]['date'],weather_data[2]['temperature'],weather_data[2]['weather'] ,weather_data[2]['wind'])
    future3='\t%s \n\t\t\t\t温度：%s\n\t\t\t\t天气：%s\n\t\t\t\t风向：%s\n ' % (weather_data[3]['date'],weather_data[3]['temperature'],weather_data[3]['weather'] ,weather_data[3]['wind'])
    future_weather='未来三天天气：\n'+future1+future2+future3
	
    str = str0 + str1 + str2 + str3 + str4 + str5 + str6 + str7 + str8 + str9 + str10 + str11+future_weather
    return str

 

PC上面的UI界面

将这个功能做成有UI界面的，可以输入一下城市，显示出该城市的天气情况，

核心代码如下：

def GUI():
	window=tk.Tk()
	#window.geometry('800*600')
	window.title('天气预报')

	def checkPassword():
		entercity = passwordEntry.get()
		confirmLable.delete(0,tk.END)

		weather=send_weather(entercity)

		for i in weather.split('\n'):
			confirmLable.insert(tk.END,i)


	passwordLabel=tk.Label(window,text='请输入城市',height=2,width=10,font=("Times", 10,'bold'),fg='red')
	passwordLabe = tk.Label(window,text='例如北京，张家界',height=2,width=10,font=('Times',10),fg='red')


	e=StringVar()
	passwordEntry =tk.Entry(window,width=25,textvariable=e,font=('Times',20,"bold"))
	e.set('北京')
	button=tk.Button(window,text='确定',command=checkPassword)

	confirmLable=tk.Listbox(window,height=10,width=45,font=('Times',20,'bold'),fg='blue',bg='#EEE5DE')

	passwordLabel.pack()
	passwordLabe.pack()
	passwordEntry.pack()
	button.pack()
	confirmLable.pack()

	window.mainloop()
GUI()

运行程序，效果如下：

和微信结合

大体思路是这样的，将上面UI里面换成微信好友的list，然后呢，微信里面，每个人都有一个地区显示，根据好友的地区向他们发送天气预报
显示上呢，前面好友名字，后面是好友所在城市，如果好友没有设置，就默认是北京

效果如下：

双击好友名字就可以直接给发送天气预报了.
