前言: 爬虫哪家强,当然是python
我是属于啥语言都用,都懂点,不精通,实际工作中能能够顶上就可以。去年写的抓取bing每日的壁纸，保存到本地，并上传到阿里云oss，如果只是本地壁纸切换，存下来就行，一直想做个壁纸站点，但最终还是没有付诸于实际行动。
一、bing壁纸介绍：
我们访问bing中国的网址https://cn.bing.com,可以看到背景是精选的图片,而且这张图片每天是不一样的,所以可以每天抓取这张图片,来作为壁纸的来源.
二、如何获取到Bing每日的壁纸：
有人会想到每日访问https://cn.bing.com 站点, 解析出网页中壁纸的所在url然后再下载图片不就可以了.这确实是一个思路,但不用这么麻烦, 其实微软官方早就给我们提供了壁纸接口.可以查询到7日内每日壁纸:
https://cn.bing.com/HPImageArchive.aspx?format=js\&idx=0%d\&n=10
访问这个url返回的数据为JSON格式,如:

"previous": "上一个图像",
"next": "下一个图像",
"walle": "此图片不能下载用作壁纸。",
"walls": "下载今日美图。仅限用作桌面壁纸。"
}
}
从json中解析可以得到images中urlbase就是我们需要的图片地址, 如3月30日的壁纸的url就是: https://cn.bing.com/th?id=OHR.SleepySloth_ZH-CN6084460583_1920x1080.jpg ,构造的图片url地址规律 https://cn.bing.com + baseurl + "_" + imagesize + ".jpg" ,我显示器的分比率是1920*1080的,所以这个分比率就够了,如果要下载最大分辨率的那么url就应该是 "https://cn.bing.com" + baseUrl + "_UHD.jpg"
三、上传阿里云OSS:
阿里云有完整的实例代码,在这里就不做过多的阐述. 可以自己去官方找文档, pip 安装下oss2的库,import 进去就可以使用.
四、完整的Python代码：
python
import json
import logging
import os
import pymysql
import requests
import oss2
forder = "f:\\BingImage\\" # 图片存放的目录
db = pymysql.connect(host='mysql数据库地址', user='用户名', password='密码', port=3306,
db='数据库')
cursor = db.cursor()
insertsql = "insert into bingimage(imgDes,imgUrl,imgSize,pubDate,getDate,ifDown,baseUrl,title,hsh,ifup) values(%s,%s,%s,%s,current_time ,1,%s,%s,%s,%s)"
checksql = "select count(*) from bingimage where baseUrl =%s"
accessKeyId = '' //阿里云accessKeyId
accessKeySecret = '' //阿里云accessKeySecret
auth = oss2.Auth(accessKeyId, accessKeySecret)
bucket = oss2.Bucket(auth, 'https://oss-cn-shenzhen.aliyuncs.com', 'imagefrombing')
try:
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36"
}
res = requests.get("https://cn.bing.com/HPImageArchive.aspx?format=js&idx=0%d&n=10",headers =headers)
data = json.loads(res.text)
for img in data['images']:
hsh = img['hsh']
baseUrl = img['urlbase']
cursor.execute(checksql,(baseUrl))
row = cursor.fetchone()
if row[0] ==0 :
pubDate = img['startdate']
imgDes = img['copyright']
title = img['title']
imgSize='1920x1080'
imgUrl = "https://cn.bing.com" + baseUrl + "_" + imgSize + ".jpg"
r = requests.get(imgUrl)
imgName = baseUrl.replace("/th?id=","") + "_" + imgSize + ".jpg"
with open(forder +pubDate + "-" + imgName,"wb") as f :
f.write(r.content)
if os.path.exists(forder +pubDate + "-" + imgName) :
cursor.execute(insertsql, (imgDes, imgUrl, imgSize, pubDate, baseUrl, title, hsh,0))
db.commit()
print(hsh + "-" + imgSize + "-下载完毕")
imgSize='UHD'
imgUrl = "https://cn.bing.com" + baseUrl + "_" + imgSize + ".jpg"
r = requests.get(imgUrl)
imgName = baseUrl.replace("/th?id=", "") + "_" + imgSize + ".jpg"
with open(forder + pubDate + "-" + imgName, "wb") as f:
f.write(r.content)
if os.path.exists(forder + pubDate + "-" + imgName):
with open(forder + pubDate + "-" + imgName, "rb") as f2:
bucket.put_object(pubDate + "-" + imgName, f2)
cursor.execute(insertsql, (imgDes, imgUrl, imgSize, pubDate, baseUrl, title, hsh,1))
db.commit()
print(hsh + "-" + imgSize + "-下载完毕")
else :
print(hsh + '已经存在数据库')
except Exception as e:
logging.Logger.info(e)
db.close()五、每日下载的实现：
windows下做个地址任务，每天定时执行两次这个python的脚本就可以了。
六、win11设置壁纸轮换：
在控制面板-》个性化-》背景里面设置
