极速数据查询天气的接口

注册了个账号，然后用python接口调用，如下是官方给出的python2的接口调用方式：

#!/usr/bin/python
# encoding:utf-8
 
import urllib2, json, urllib
 
 
#  1、天气预报查询
 
 
data = {}
data["appkey"] = "your_appkey_here"
data["city"] = "杭州"
data["cityid"] = "111"#任选
data["citycode"] ="101260301"#任选
 
url_values = urllib.urlencode(data)
url = "http://api.jisuapi.com/weather/query" + "?" + url_values
result = urllib2.urlopen(url)
jsonarr = json.loads(result.read())
 
if jsonarr["status"] != u"0":
    print jsonarr["msg"]
    exit()
result = jsonarr["result"]
print result["city"],result["cityid"],result["citycode"],result["date"],result["week"],result["weather"],result["temp"]
print result["temphigh"],result["templow"],result["img"],result["humidity"],result["pressure"],result["windspeed"],result["winddirect"]
print result["windpower"],result["updatetime"]
print "指数:"
for i in result["index"]:
    if i.has_key("ivalue"):
        print i["iname"],i["ivalue"],i["detail"]
    else:
        print i["iname"],i["index"],i["detail"]
 
print "空气质量指数："
aqi = result["aqi"]
print aqi["so2"],aqi["so224"],aqi["no2"],aqi["no224"],aqi["co"]
print aqi["co24"],aqi["o3"],aqi["o38"],aqi["o324"],aqi["pm10"]
print aqi["pm1024"],aqi["pm2_5"],aqi["pm2_524"],aqi["iso2"],aqi["ino2"]
print aqi["ico"],aqi["io3"],aqi["io38"],aqi["ipm10"],aqi["ipm2_5"]
print aqi["aqi"],aqi["primarypollutant"],aqi["quality"],aqi["timepoint"]
print aqi["aqiinfo"]["level"],aqi["aqiinfo"]["color"],aqi["aqiinfo"]["affect"],aqi["aqiinfo"]["measure"]
 
print "未来几天天气："
for daily in result["daily"]:
    print daily["date"],daily["week"],daily["sunrise"],daily["sunset"]
    print daily["night"]["weather"],daily["night"]["templow"],daily["night"]["img"],daily["night"]["winddirect"],daily["night"]["windpower"]
    print daily["day"]["weather"],daily["day"]["img"],daily["day"]["winddirect"],daily["day"]["windpower"]
 
print "未来几小时天气："
for hourly in result["hourly"]:
    print hourly["time"],hourly["weather"],hourly["temp"],hourly["img"]

我自己机器是python3.6，所以需要把他的代码进行更改：

程序中的

#url_values = urllib.urlencode(data)
url_values = urllib.parse.urlencode(data)

python3用requests就可以了，不必用urllib2，因为后者是python2用的。所以

导入的包改为：

import json
import urllib
import requests

但是发现程序在

url_values = urllib.parse.urlencode(data)报错了，说是没有parse模块好像。然后我又把

import urllib

改为：

import urllib.parse

这样就错误就解决了（奇怪的是后来我又改成import urllib，但是却不报错了，奇怪~）。

　　程序还有另外两处改动，改动如下：

#result = urllib2.urlopen(url)
result = requests.get(url).text
#jsonarr = json.loads(result.read())
jsonarr = json.loads(result)

　　最后可以正确跑通调用的程序如下：

#!/usr/bin/python
# encoding:utf-8
 
#import urllib2, json, urllib
import json
import urllib
import requests
 
 
#  1、天气预报查询

data = {}
data["appkey"] = "你自己注册的"
data["city"] = "杭州"

#url_values = urllib.urlencode(data)
url_values = urllib.parse.urlencode(data)
url = "http://api.jisuapi.com/weather/query" + "?" + url_values
#result = urllib2.urlopen(url)
result = requests.get(url).text
#jsonarr = json.loads(result.read())
jsonarr = json.loads(result)
 
if jsonarr["status"] != u"0":
    print (jsonarr["msg"])
    exit()
result = jsonarr["result"]

print ("天气情况：")
#print('type(result["daily"])',type(result["daily"]))
daily = result["daily"][0]
print('最高气温，最低气温:')
print(daily["day"]["temphigh"])
print(daily["night"]["templow"])


print (daily["date"],daily["week"])
print (daily["day"]["weather"],daily["day"]["winddirect"],daily["day"]["windpower"])
print (daily["night"]["weather"],daily["night"]["winddirect"],daily["day"]["windpower"])

print('今天'+','+result["city"] + ','+'白天天气' + daily["day"]["weather"]+ ',' +'风向'+ daily["day"]["winddirect"] 
+','+'夜间天气' + daily["day"]["weather"] +','+'风向'+ daily["day"]["winddirect"] +'.' + '最高气温' +daily["day"]["temphigh"] +'度' +'最低气温'+ daily["night"]["templow"] +'度')
