基于MQTT的桌面天气提醒助理
本帖最后由 hmilycheng 于 2022-9-19 21:13 编辑一、项目灵感
1、每日早晨起来，需要查看当日的天气预报，来决定今天所穿的衣服。
2、每日睡觉前，需要查看次日的课程表来整理书包。
3、有时需要远程发布提醒信息。
二、硬件组成
行空板 x1
三、软件与程序
（一）Mind+连接行空板
1、使用Type c数据线将行空板连接到电脑，并切换到Python模式。
2、依次选择“扩展-官方库-行空板”，添加行空板库。
3、
4、访问http://10.1.2.3/打开行空板设置菜单主页。
5、点击“应用开关”菜单，启用SLOT服务。
6、网络设置-连接wifi
（二）注册天气API
1、打开天气API网站https://tianqiapi.com/index
2、注册用户名并登录
3、打开API文档
4、打开免费基础实况天气
5、打开请求链接https://www.yiketianqi.com/free/day?appid=86943926&appsecret=Tj6vFcS0&unescape=1
查看数据
6、请求参数说明：
7、响应JSON
8、响应参数说明
（三）编写代码
1、mind+切换至代码模式
2、新建weather文件夹
3、weather文件夹下新建main.py文件，并编写代码
# 代码如下
from unihiker import GUI
import siot
# 事件回调函数
def on_message_callback(client, userdata, msg):
global mqtt_msg1,mqtt_msg2,mqtt_msg3
print(msg.topic)
print(msg.payload.decode())
if (msg.topic == "Msg1/txt"):
mqtt_msg1 = msg.payload.decode()
elif (msg.topic == "Msg2/txt"):
mqtt_msg2 = msg.payload.decode()
elif (msg.topic == "Msg3/txt"):
mqtt_msg3 = msg.payload.decode()
# 自定义函数
def weather_getWeather():
#天气api
weather_serveraddr = (str("https://v0.yiketianqi.com/free/day?appid="))
weather_appid = "86943926"
weather_appsecret = "Tj6vFcS0"
r = requests.get(weather_serveraddr + weather_appid + "&appsecret=" + weather_appsecret + "&cityid="+ "&unescape=1")
r.encoding = "utf-8"
data = json.loads(r.text)
print(data)
return data["city"], data["date"], data["week"], data["update_time"], data["wea"], data["wea_img"], data["tem"], data["tem_day"], data["tem_night"], data["win"], data["win_speed"], data["win_meter"], data["air"], data["pressure"], data["humidity"]

4、下载天气图标，并上传到weather文件夹下
