1. 前期准备

1.1 开发工具

Python 3.6

Pycharm Pro 2017.3.2

Text文本

1.2 Python库

requests

re

urllib

如果没有这些Python库，使用以下方法

pip install 需要安装的包名(Ps： pip install requests)

2. 配置系统主题文件

个人经过和系统主题对比写了一个主题文件代码，大家可以拷贝到text文本中另存为*.theme文件，我这里命名为lamborghini.theme

3.获取页面地址

3.1 获取需要爬取的网页地址

url:http://www.ivsky.com/search.php?q=%E5%85%B0%E5%8D%9A%E5%9F%BA%E5%B0%BC&PageNo=2
q 查询的数据
PageNo 页码

3.2 获取爬取页面分页图片地址

img_url:http://img.ivsky.com/img/bizhi/pic/201804/17/aventador_s-007.jpg

img_url:http://img.ivsky.com/img/bizhi/pre/201804/17/aventador_s-007.jpg

pic 原图

pre 缩略图

4.编写爬虫

import requests, re, urllib.request

class Ivsky_Spider:

    def __init__(self, new_search_name):

        """初始化"""

        self.url_search = 'http://www.ivsky.com/search.php?q=%s' % urllib.request.quote(new_search_name) # 网站搜索

        self.url = re.findall(r'(http://.*?)/', self.url_search)[0] # 网站地址

        self.headers = {

            'User-Agent': 'Mozilla/5.0', # 伪装成浏览器访问

            'Referer': self.url # 是否合法

        }

    def Spider(self):

                respone = self.Get_Html_Respone(self.url_search + '&PageNo=' + str(i)).text

                page_temp = re.findall(r'<div class="pagelist">.*?</div>', respone, re.S)[0]

                if str(i) in page_temp:

                else:

                    return

                i += 1

            except Exception as e:

                print('报错信息：%s\n程序退出' % e)

                return

    def Get_Html_Respone(self, new_url):

        respone = requests.get(url=new_url, headers=self.headers) # Get请求

        return respone

        for i in range(len(img_url_list)):

            print('-' * 20 + '正在下载第%d页第%d张图片' % (page, i+1) + '-' * 20)

            img_url = self.url + img_url_list[i]

            img_respone = self.Get_Html_Respone(img_url).text

            img_respone_url = re.findall(r"</script><img.*?src='(.*?)'", img_respone)[0].replace('pre', 'pic')

            img_f_name = img_respone_url[img_respone_url.rfind('/') + 1:]

            with open('D:\Wallpaper\lamborghini\%s' % img_f_name, 'wb') as f:

                img_result = self.Get_Html_Respone(img_respone_url).content

                f.write(img_result)

            with open('C:\\Users\Administrator\AppData\Local\Microsoft\Windows\Themes\lamborghini.theme', 'a') as f:

                f.write('\n')

                f.write('Item%dPath=D:\Wallpaper\lamborghini\%s' % (i, img_f_name))

if __name__ == '__main__':

    a = Ivsky_Spider(search_name)

    a.Spider()
