一、开通接口

天气预报接口服务使用的聚合数据提供的免费接口,每天可以100次免费调用。可以通过https://www.juhe.cn/docs/api/id/73注册及开通。

二、Python2.x调用示例

#!/usr/bin/python
# -*- coding: utf-8 -*-

import urllib, urllib2, sys, json

reload(sys)
sys.setdefaultencoding('utf-8')

url = 'http://apis.juhe.cn/simpleWeather/query'

params = {
    "city": "北京",  # 查询天气的城市名称,如:北京、苏州、上海
    "key": "xxxxxxxx",  # 您申请的接口API接口请求Key
}
querys = urllib.urlencode(params)

request = urllib2.Request(url, data=querys)
response = urllib2.urlopen(request)
content = response.read()
if (content):
    try:
        result = json.loads(content)
        error_code = result['error_code']
        if (error_code == 0):
            temperature = result['result']['realtime']['temperature']
            humidity = result['result']['realtime']['humidity']
            info = result['result']['realtime']['info']
            wid = result['result']['realtime']['wid']
            direct = result['result']['realtime']['direct']
            power = result['result']['realtime']['power']
            aqi = result['result']['realtime']['aqi']
            print("温度:%s\n湿度:%s\n天气:%s\n天气标识:%s\n风向:%s\n风力:%s\n空气质量:%s" % (temperature, humidity, info, wid, direct, power, aqi))
        else:
            print("请求失败:%s %s" % (result['error_code'], result['reason']))
    except Exception as e:
        print("解析结果异常:%s" % e)
else:
    # 可能网络异常等问题,无法获取返回内容,请求异常
    print("请求异常")

三、Python3.x调用示例

#!/usr/bin/python
# -*- coding: utf-8 -*-

import urllib
import urllib.request as request
import urllib.error as error
import json


# 天气预报查询示例
def main():
    api_url = 'http://apis.juhe.cn/simpleWeather/query'
    params_dict = {
        "city": "北京",  # 查询天气的城市名称,如:北京、苏州、上海
        "key": "xxxxxxxx",  # 您申请的接口API接口请求Key
    }
    params = urllib.parse.urlencode(params_dict)
    try:
        req = request.Request(api_url, params.encode())
        response = request.urlopen(req)
        content = response.read()
        if content:
            try:
                result = json.loads(content)
                error_code = result['error_code']
                if (error_code == 0):
                    temperature = result['result']['realtime']['temperature']
                    humidity = result['result']['realtime']['humidity']
                    info = result['result']['realtime']['info']
                    wid = result['result']['realtime']['wid']
                    direct = result['result']['realtime']['direct']
                    power = result['result']['realtime']['power']
                    aqi = result['result']['realtime']['aqi']
                    print("温度:%s\n湿度:%s\n天气:%s\n天气标识:%s\n风向:%s\n风力:%s\n空气质量:%s" % (
                        temperature, humidity, info, wid, direct, power, aqi))
                else:
                    print("请求失败:%s %s" % (result['error_code'], result['reason']))
            except Exception as e:
                print("解析结果异常:%s" % e)
        else:
            # 可能网络异常等问题,无法获取返回内容,请求异常
            print("请求异常")
    except error.HTTPError as err:
        print(err)
    except error.URLError as err:
        # 其他异常
        print(err)


if __name__ == '__main__':
    main()

四、返回结果
