[作品提交] 【得捷电子Follow me第2期】任务4：分任务1：日历&时钟

这篇来学习下网络获取日历时钟和天气信息，CircuitPython编程语言还是第一次使用，还有许多不太明白的，后续再慢慢学习。

这个测试代码部分参考坛友的，下面来学习下网络测试功能。

1、复制文件到开发板盘符/lib文件下

2、测试代码

copy.py

import board, os, wifi
import time
import ssl
import socketpool
import adafruit_requests

from adafruit_display_text import label, wrap_text_to_lines
from adafruit_bitmap_font import bitmap_font

color = 0xFFFFFF
font = bitmap_font.load_font("fonts\wenquanyi_10pt.pcf")

display = board.DISPLAY
display.brightness = 1 
display.rotation = 0 

JSON_TIME_URL = "http://quan.suning.com/getSysTime.do"
JSON_weather_URL = "http://t.weather.sojson.com/api/weather/city/{}"

pool = socketpool.SocketPool(wifi.radio)
requests = adafruit_requests.Session(pool, ssl.create_default_context())

def refresh_screen(print_text):
    text_area = label.Label(font, text=print_text, scale=1)
    text_area.x = 5
    text_area.y = 15
    text_area.scale = 1
    text_area.color = color
    display.show(text_area)

def get_data():
    try:
        response = requests.get(JSON_TIME_URL)
    except ConnectionError as e:
        print("Connection Error:", e)
        print("Retrying in 60 seconds")
    time_data = response.json()['sysTime2'][:-3]

    try:
        city_code = "101180101"
        url = JSON_weather_URL.format(city_code)
        response = requests.get(url)
    except ConnectionError as e:
        print("connect error:{},retry in 60s".format(e))
    weather_data = response.json()
    cityInfo = weather_data['cityInfo']
    city_weather = weather_data['data']
    forecast = city_weather['forecast']
    dis_str = cityInfo['city'] + ' ' + forecast[0]['week']
    dis_str += "\n时间:"+time_data
    dis_str += "\n温度："+city_weather['wendu']+"℃"
    dis_str += "\n湿度：" + city_weather['shidu']
    dis_str += '\n空气质量：' + city_weather['quality']
    return dis_str

while not wifi.radio.ipv4_address:
    try:
        wifi.radio.connect('TP-LINK', '66668888')
    except ConnectionError as e:
        print("connecti error:{},retry in 2s".format(e))
    time.sleep(2)
    
print("get ip:", wifi.radio.ipv4_address)

while True:
    info = get_data()
    refresh_screen(info)
    time.sleep(60)

3、运行

获取的天气信息显示在LCD上

注意还要写一个总贴   

好的
