The first instance of crawler environment was completed in Python. Today, we continue the second project: crawler all the images of a website, see a website, want to save the pictures of the local, so, look down:

Crawl target website: blog.csdn.net/qq_42363090…

1: Ensure that the Requests module is installed. If not, install the requests module using the following command:

pip install requests
Copy the code

Module Requests was installed successfully

2: Create a first.py file and write the following code

import requests
import re
import os
class GetImage(object) :
    def __init__(self,url) :
        self.url = url
        self.headers = {
            'User-Agent': 'the Mozilla / 5.0 (Windows NT 10.0; Win64; X64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36'
        }
        self.dir_path = os.path.dirname(os.path.abspath(__file__))
        self.path = self.dir_path+'/imgs'
        isExists = os.path.exists(self.dir_path+'/imgs')
        Create a directory
        if not isExists:
            os.makedirs(self.path)

    def download(self,url) :
        try:
            res = requests.get(url,headers=self.headers)
            return res
        except Exception as E:
            print(url+'Download failed, cause :'+E)


    def parse(self,res) :
        content = res.content.decode()
        # print(content)
        img_list = re.findall(r',content,re.S)
        img_list = ['http://www.yangqq.com/skin/jxhx/'+url for url in img_list]
        return img_list

    def save(self,res_img,file_name) :
        if res_img:
            with open(file_name,'wb') as f:
                f.write(res_img.content)
            print(url+'Download successful')

    def run(self) :
        # download
        res = self.download(self.url)
        # parse
        url_list = self.parse(res)
        # Download image
        for url in url_list:
            res_img = self.download(url)
            name = url.strip().split('/').pop()
            file_name = self.path+'/'+name
            # save
            self.save(res_img,file_name)

if __name__ == '__main__':
    url_list = ['https://www.yangqq.com/skin/jxhx/'.'https://www.yangqq.com/skin/jxhx/list.html'.'https://www.yangqq.com/skin/jxhx/share.html'.'https://www.yangqq.com/skin/jxhx/list2.html'.'https://www.yangqq.com/skin/jxhx/list3.html'.'https://www.yangqq.com/skin/jxhx/daohang.html'.'https://www.yangqq.com/skin/jxhx/about.html']
    for url in url_list:
        text = GetImage(url)
        text.run()
Copy the code

3: Right click the run button on the file, and the result is as follows

Ok, finish
