美食网站 原型 html 下载,网站咨询弹窗是怎么做的,j2ee博客网站开发,上海万户信息技术有限公司前言: 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#xff0c;保存到本地#xff0c;并上传到阿里云oss#xff0c;如果只是本地壁纸切换#xff0c;存下来就行#xff0c;一直想做个壁纸站点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?formatjsidx0%dn10 访问这个url返回的数据为JSON格式,如: {images: [{startdate: 20240329,fullstartdate: 202403291600,enddate: 20240330,url:

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?idOHR.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         import json import logging import osimport pymysql import requests import oss2 forder f:\\BingImage\\ # 图片存放的目录 db pymysql.connect(hostmysql数据库地址, user用户名, password密码, port3306,db数据库) cursor db.cursor() insertsql insert into bingimage(imgDes,imgUrl,imgSize,pubDate,getDate,ifDown,baseUrl,title,hsh,ifup)
