关于api:基于Python的免费天气预报接口查询

本文转自 SDK 社区：sdk.cn

一、开明接口

天气预报接口服务应用的聚合数据提供的收费接口，每天能够 100 次收费调用。能够通过 https://www.juhe.cn/docs/api/id/73 注册及开明。

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",  # 查问天气的城市名称，如：北京、苏州、上海
"key": "xxxxxxxx",  # 您申请的接口 API 接口申请 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("申请失败:%s %s" % (result['error_code'], result['reason']))
except Exception as e:
    print("解析后果异样：%s" % e)
else:
# 可能网络异样等问题，无奈获取返回内容，申请异样
print("申请异样")

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


# 天气预报查问示例
def main():
api_url = 'http://apis.juhe.cn/simpleWeather/query'
params_dict = {
    "city": "北京",  # 查问天气的城市名称，如：北京、苏州、上海
    "key": "xxxxxxxx",  # 您申请的接口 API 接口申请 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("申请失败:%s %s" % (result['error_code'], result['reason']))
        except Exception as e:
            print("解析后果异样：%s" % e)
    else:
        # 可能网络异样等问题，无奈获取返回内容，申请异样
        print("申请异样")
except error.HTTPError as err:
    print(err)
except error.URLError as err:
    # 其余异样
    print(err)

if __name__ == '__main__':
main()

四、返回后果
