API 百度APIstore
有一个天气api 百度APISTORE 获取验证码,地下有个python代码范例
今天写的代码
如果直接通过api得到的结果是一串.人类看不懂

把结果复制到jsbeautifer.org解析,分析结果
复制进去,点beautiful js or html
美化网站
编写程序获取上海的天气结果
# -*- coding: utf-8 -*-
import requests
#导入requests库
import json
#导入jason库,是一个把数据变成字典的库
url = 'http://apis.baidu.com/heweather/weather/free?city=shanghai'
# url 尾巴是城市的名字
key = '9d2576232a5ccda59d47f67cc672c315'
# key是在百度apistore上的到的key
headers = {
'apikey': key
}
r = requests.get(url, headers = headers)
# print(r.text)
weather_info = json.loads(r.text)
#用json解析
# print(weather_info.keys())
weather_data = weather_info['HeWeather data service 3.0'][0]
daily_forecast = weather_data['daily_forecast']
# print(len(weather_data),weather_data)
# weather_data长度只有1,列表里面只有一个字典元素
forecast = []
for f in daily_forecast:
print('天气',f['date'],f['tmp']['max'], f['tmp']['min'])
date = f['date']
max = f['tmp']['max']
min = f['tmp']['min']
forecast.append([date, max, min])
# 获取的结果以数组返回
print(forecast)
结果
[['2016-06-22', '30', '25'],
['2016-06-23', '34', '26'],
['2016-06-24', '33', '23'],
['2016-06-25', '28', '23'],
['2016-06-26', '28', '24'],
['2016-06-27', '30', '24'],
['2016-06-28', '27', '23']]
输出结果可以作为数据画出折线图, 科科一个这样的程序就这样出来了
