The development of preparation

  • 1. First, ensure the integrity of the current firmware dependency package
  • The effect is shown below. If you do not have two dependency packages on the diagram, please burn the latest firmware.

Prepare the weather API

"city": "jingzhou",
"cityid": "101200801",
"img1": "n7.gif",
"img2": "d2.gif",
"ptime": "18:00",
"temp1": "16℃",
"temp2": "23℃",
"weather": "Rain turns shade"

We can analyze these json files and write an example like this

example analyse

import urequests
from microbit import * 

def get_weather():
	url = "http://www.weather.com.cn/data/cityinfo/101200801.html"
	rsp = urequests.get(url)
	data = eval(rsp.text) # eval function is used to convert string type json data from -> to python dictionary type
	weather = data["weatherinfo"]
	L = weather["temp1"] #lowest temperature
	H = weather["temp2"] #the highest temperature
	return "L:" + L[:-1] + " H:" + H[:-1] #Data sample->  L:16 H:23


# L[:-1] H[:-1]Remove ℃ ℉ and two special symbol, can appear otherwise coding errors
