python天气预报数据库,基于Python的免费天气预报接口查询

本文转自SDK社区&＃xff1a;sdk.cn

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&＃xff0c;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(&＃39;utf-8&＃39;)

url &＃61; &＃39;http://apis.juhe.cn/simpleWeather/query&＃39;

params &＃61; {

"city": "北京", # 查询天气的城市名称&＃xff0c;如&＃xff1a;北京、苏州、上海

"key": "xxxxxxxx", # 您申请的接口API接口请求Key

}

querys &＃61; urllib.urlencode(params)

request &＃61; urllib2.Request(url, data&＃61;querys)

response &＃61; urllib2.urlopen(request)

content &＃61; response.read()

if (content):

try:

result &＃61; json.loads(content)

error_code &＃61; result[&＃39;error_code&＃39;]

if (error_code &＃61;&＃61; 0):

temperature &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;temperature&＃39;]

humidity &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;humidity&＃39;]

info &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;info&＃39;]

wid &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;wid&＃39;]

direct &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;direct&＃39;]

power &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;power&＃39;]

aqi &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;aqi&＃39;]

print("温度&＃xff1a;%s\n湿度&＃xff1a;%s\n天气&＃xff1a;%s\n天气标识&＃xff1a;%s\n风向&＃xff1a;%s\n风力&＃xff1a;%s\n空气质量&＃xff1a;%s" % (temperature, humidity, info, wid, direct, power, aqi))

else:

print("请求失败:%s %s" % (result[&＃39;error_code&＃39;], result[&＃39;reason&＃39;]))

except Exception as e:

print("解析结果异常&＃xff1a;%s" % e)

else:

# 可能网络异常等问题&＃xff0c;无法获取返回内容&＃xff0c;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 &＃61; &＃39;http://apis.juhe.cn/simpleWeather/query&＃39;

params_dict &＃61; {

"city": "北京", # 查询天气的城市名称&＃xff0c;如&＃xff1a;北京、苏州、上海

"key": "xxxxxxxx", # 您申请的接口API接口请求Key

}

params &＃61; urllib.parse.urlencode(params_dict)

try:

req &＃61; request.Request(api_url, params.encode())

response &＃61; request.urlopen(req)

content &＃61; response.read()

if content:

try:

result &＃61; json.loads(content)

error_code &＃61; result[&＃39;error_code&＃39;]

if (error_code &＃61;&＃61; 0):

temperature &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;temperature&＃39;]

humidity &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;humidity&＃39;]

info &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;info&＃39;]

wid &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;wid&＃39;]

direct &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;direct&＃39;]

power &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;power&＃39;]

aqi &＃61; result[&＃39;result&＃39;][&＃39;realtime&＃39;][&＃39;aqi&＃39;]

print("温度&＃xff1a;%s\n湿度&＃xff1a;%s\n天气&＃xff1a;%s\n天气标识&＃xff1a;%s\n风向&＃xff1a;%s\n风力&＃xff1a;%s\n空气质量&＃xff1a;%s" % (

temperature, humidity, info, wid, direct, power, aqi))

else:

print("请求失败:%s %s" % (result[&＃39;error_code&＃39;], result[&＃39;reason&＃39;]))

except Exception as e:

print("解析结果异常&＃xff1a;%s" % e)

else:

# 可能网络异常等问题&＃xff0c;无法获取返回内容&＃xff0c;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__ &＃61;&＃61; &＃39;__main__&＃39;:

main()
