Python之简单爬取图片并保存到本地文件夹。

Python爬取图片项目介绍

• 网址地址：https://500px.com/popular
• 第三方库：requests,fake_useragent(产生随机请求头进行访问)
• 代码实现：

import requests
from fake_useragent import UserAgent



filename=0
class photo_spider(object):
    def __init__(self):
        self.url = 'https://api.500px.com/v1/photos?rpp=50&feature=popular&image_size%5B%5D=1&image_size%5B%5D=2&image_size%5B%5D=32&image_size%5B%5D=31&image_size%5B%5D=33&image_size%5B%5D=34&image_size%5B%5D=35&image_size%5B%5D=36&image_size%5B%5D=2048&image_size%5B%5D=4&image_size%5B%5D=14&sort=&include_states=true&include_licensing=true&formats=jpeg%2Clytro&only=&exclude=&personalized_categories=&page={}&rpp=50'
        ua = UserAgent(verify_ssl=False)
        # 产生随机的UserAgent请求头进行访问。
        for i in range(1, 100):
            self.headers = {
                'User-Agent': ua.random
            }

    #发送请求，获取网页。
    def get_html(self,url):
        response=requests.get(url,headers=self.headers)
        html = response.json()
        return html

    #获取图片链接地址，保存图片格式到本地文件夹。
    def get_imageUrl(self,html):
        global filename
        content_list=html['photos']
        for content in content_list:
            image_url = content['image_url']
            # print(image_url[8])
            imageUrl = image_url[8]
            r = requests.get(imageUrl, headers=self.headers)
            with open('D:/pycharm文件/photo/' + str(filename) + '.jpg', 'wb') as f:
                f.write(r.content)
                filename += 1

        #获取多页及函数调用
        def main(self):
            start = int(input('输入开始：'))
            end = int(input('输入结束页：'))
            for page in range(start, end + 1):
                print('第%s页' % page)
                url = self.url.format(page)
                html = self.get_html(url)
                self.get_imageUrl(html)

        if __name__ == '__main__':
            spider = photo_spider()
            spider.main()
