获取bing每日图片

http://global.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1&mkt=en-US

其中idx表示倒数第几张图片0就是今天的1就是昨天的几就是几天前的每日图片

返回XML简单明了

用python获取返回的XML并用正则表达式找出图片的URL，用PyMySQL将其插入数据库供日后使用

我服务器上的代码如下

 from urllib import request
 import re
 import requests
 import pymysql

 def insertPic(picName):
     connect = pymysql.connect(host='localhost', user='jeff', password='xxxx', db='jeff',charset='utf8')
     cur = connect.cursor()
     sql = 'INSERT bingPic(name) VALUES(%s)'
     cur.execute(sql, (picName))
     connect.commit()
     connect.close()

 def getXML(url):
     page = request.urlopen(url)
     return page.read().decode('utf-8')

 def saveImage(directory, imageURL, imageName):
     image = open(directory + imageName, 'wb')
     image.write(requests.get(imageURL).content)
     image.close()

 globalBing = 'http://global.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1&mkt=en-US'
 chinaBing = 'http://www.bing.com/HPImageArchive.aspx?format=xml&idx=0&n=1'
 path = '/home/jeff/web/resources/pic/bing/'

 xmlGlobal = getXML(globalBing)

 p = re.compile("<url>.*</url>")
 result = re.findall(p, xmlGlobal)
 picUrl = 'http://global.bing.com' + result[0][5:-6]
 picName = picUrl.split('/')[-1]

 saveImage(path, picUrl, picName)
 insertPic(picName)
 print(picName)
