Python之自动爬取每日bing壁纸并更换

今天，我们来研究——Python自动爬取每日bing壁纸
说到Python想必大家对这个编辑器并不陌生。当然，最出名的，也就是他的爬虫了

咳咳咳…….这里我就不详细逐一介绍了，我们直接开门见山

一、你需要准备

Python编译器
Pycharm（有条件者可以去官网买）

Pyinstaller,requests第三方库

二、使用Python自带的pip进行安装库

同时摁下win+r键，输入cmd进入提示命令符
输入 pip install ******

Tip: *号处可使用任何要按照第三方库的名称
这里只安装：requests和pyinstaller

三、函数__photo__.py爬取必应每日一图

[Python] 纯文本查看 复制代码

import re
import requests
import datetime
from __computerbackground__ import __computerbackground__
import os
def __photo__( ):
  url = 'https://www.bing.com/'
  html = requests.get(url).text
  #获取这个网页源码
  Nurl = re.findall('id="bgLink" rel="preload" href="(.*?)&',html,re.S)
  #正则表达式写好
  for temp in Nurl:
   #循环获取里边的图片，其实这里只有一个
        url = 'https://www.bing.com' + temp
        #print(url)
        pic = requests.get(url)
        a=(os.path.dirname(__file__) ) #获取当前路径
    #接着把图片保存下来，再提前准备一个Photo目录用来存放
        name = str(datetime.datetime.now().year)+'-'+str(datetime.datetime.now().month)+'-'+str(datetime.datetime.now().day) + '.jpg'
        file=a+'/Photo'+'/'+name #建立保存的绝对地址
        #print(file)
        while True:
            try:
                fp = open(file, 'wb')
                fp.write(pic.content)
                fp.close()  # 保存图片到Photo这个文件夹
                print('已将图片保存于', file)
                break
            except:
                print('发生错误！！请检查是否在', a, '中创建Photo名称的文件夹')
                b = input('创建确定请输入1:')
                                        #保存图片到

Tip:如果显示报错，你必须在运行本脚本的目录中创建一个Photo的文件夹，不然将无法保存！！

三、函数__computerbackground__.py更换壁纸

[Python] 纯文本查看 复制代码

import ctypes
import datetime
import time
import os
def __computerbackground__():
    #print(os.path.dirname(__file__))
    a=(os.path.dirname(__file__) )
    name=str(datetime.datetime.now().year)+'-'+str(datetime.datetime.now().month)+'-'+str(datetime.datetime.now().day) + '.jpg'
    time.sleep(1)
    file=a+"/Photo"+"/"+name
    #print(file)
    ctypes.windll.user32.SystemParametersInfoW(20,  0,file, 0)  #替换壁纸
    print('更换成功')

Tip:没有安装上ctypes库的将无法使用

三、主程序photo_get.py调用函数

[Python] 纯文本查看 复制代码

from __photo__ import __photo__
if __name__=='__main__':
    __photo__()

四、打包exe

同时摁下win+r键，输入cmd进入提示命令符
输入 cd D:/****** (注意：**处即为脚本photo_get.py运行所在文件夹)
输入pyinstaller -D photo_get.py
