6. 将此网址输入浏览器可获得 : 
	{"code":"200","updateTime":"2021-05-03T11:35+08:00","fxLink":"http://hfx.link/2ra1","daily":[{"fxDate":"2021-05-03","sunrise":"05:37","sunset":"19:11","moonrise":"01:00","moonset":"11:05","moonPhase":"亏凸月","tempMax":"20","tempMin":"14","iconDay":"305","textDay":"小雨","iconNight":"101","textNight":"多云","wind360Day":"135","windDirDay":"东南风","windScaleDay":"1-2","windSpeedDay":"3","wind360Night":"315","windDirNight":"西北风","windScaleNight":"4-5","windSpeedNight":"34","humidity":"20","precip":"2.5","pressure":"996","vis":"24","cloud":"64","uvIndex":"3"},{"fxDate":"2021-05-04","sunrise":"05:36","sunset":"19:12","moonrise":"01:46","moonset":"12:09","moonPhase":"下弦月","tempMax":"26","tempMin":"11","iconDay":"104","textDay":"阴","iconNight":"101","textNight":"多云","wind360Day":"315","windDirDay":"西北风","windScaleDay":"4-5","windSpeedDay":"34","wind360Night":"315","windDirNight":"西北风","windScaleNight":"3-4","windSpeedNight":"16","humidity":"27","precip":"0.0","pressure":"997","vis":"25","cloud":"0","uvIndex":"11"},{"fxDate":"2021-05-05","sunrise":"05:35","sunset":"19:13","moonrise":"02:24","moonset":"13:12","moonPhase":"残月","tempMax":"25","tempMin":"15","iconDay":"104","textDay":"阴","iconNight":"150","textNight":"晴","wind360Day":"180","windDirDay":"南风","windScaleDay":"3-4","windSpeedDay":"16","wind360Night":"225","windDirNight":"西南风","windScaleNight":"3-4","windSpeedNight":"16","humidity":"36","precip":"0.0","pressure":"998","vis":"25","cloud":"0","uvIndex":"4"}],"refer":{"sources":["Weather China"],"license":["no commercial use"]}}
7. 排布 
	为了更加精确地获得数据,需要将上述数据排布处理(加一些回车便于观察)一下 : 
	{"code":"200","updateTime":"2021-05-02T15:35+08:00","fxLink":"http://hfx.link/2ra1",
	"daily":
	[
		{"fxDate":"2021-05-02","sunrise":"05:38","sunset":"19:10","moonrise":"00:05","moonset":"10:00","moonPhase":"亏凸月","tempMax":"22","tempMin":"15","iconDay":"104","textDay":"阴","iconNight":"305","textNight":"小雨","wind360Day":"90","windDirDay":"东风","windScaleDay":"3-4","windSpeedDay":"16","wind360Night":"45","windDirNight":"东北风","windScaleNight":"1-2","windSpeedNight":"3","humidity":"57","precip":"0.0","pressure":"998","vis":"25","cloud":"5","uvIndex":"5"},
		{"fxDate":"2021-05-03","sunrise":"05:37","sunset":"19:11","moonrise":"01:00","moonset":"11:05","moonPhase":"亏凸月","tempMax":"21","tempMin":"14","iconDay":"305","textDay":"小雨","iconNight":"101","textNight":"多云","wind360Day":"45","windDirDay":"东北风","windScaleDay":"1-2","windSpeedDay":"3","wind360Night":"315","windDirNight":"西北风","windScaleNight":"4-5","windSpeedNight":"34","humidity":"20","precip":"5.1","pressure":"996","vis":"25","cloud":"80","uvIndex":"3"},

	],
	"refer":{"sources":["Weather China"],"license":["no commercial use"]}
	}

3.编写 Python (在树莓派自带的 Thonny IDE上编译)

import requests

# 填入 请求
url = 'https://devapi.qweather.com/v7/weather/3d' 

# 填入 地址 和 你的KEY
value = {
    'location': '101180501',
    'key': 'fed098f400e84c8a9f029bcb72c1197d',
#    'lang': 'zh'
}

sd = requests.get(url, params=value)
sds = sd.json()

#从网址内获取指定数据
#具体 关键词 详见官方 API 手册的解释

for i in range(3):
    sdf = sds['daily'][i]['fxDate'] #date
    Mo  = '平顶山 ' + sdf
    sdf = sds['daily'][i]['textDay'] #date
    Mo  = Mo + '     ' + sdf + '\n'
    sdf = sds['daily'][i]['tempMax'] #Max tempurture
    Mo  = Mo + '最高温度: ' + sdf + '℃   '
    sdf = sds['daily'][i]['tempMin'] #Mai tempurture
    Mo  = Mo + '最低温度: ' + sdf + '℃   ' + '\n'
    sdf = sds['daily'][i]['windScaleNight'] 
    Mo  = Mo + '风力等级: ' + sdf + '   '
    sdf = sds['daily'][i]['windDirDay'] 
    Mo  = Mo + '风向: ' + sdf + '    ' + '\n'
    sdf = sds['daily'][i]['vis'] 
    Mo  = Mo + '能见度: ' + sdf + 'KM  '
    sdf = sds['daily'][i]['moonPhase'] 
    Mo  = Mo + '  月相: ' + sdf 
    sdf = sds['daily'][i]['cloud'] 
    Mo  = Mo + '    云量 : ' + sdf + ' % \n'
    print(Mo)

• 编译结果 :

平顶山 2021-05-03 小雨
最高温度: 20℃ 最低温度: 14℃
风力等级: 4-5 风向: 东南风
能见度: 24KM 月相: 亏凸月 云量 : 64 %

平顶山 2021-05-04 阴
最高温度: 26℃ 最低温度: 11℃
