如何将图片从网站保存到本地文件夹 [英] How to save pictures from a website to a local folder

问题描述

我需要将来自该网站的图片保存在一个文件夹中:

I'd need to save pictures from this website in a folder:

http://www.photobirdireland.com/garden-birds.html

我已经尝试过使用import os

I've tried by using import os

from lxml import html
from urllib.request import urlopen
from bs4 import BeautifulSoup as bs


class ImageScraper:
    def __init__(self, url, download_path):
        self.url = url
        self.download_path = download_path

        self.session = requests.Session()

    def scrape_images(self):

        html = urlopen(url)
        bs4 = bs(html, 'html.parser')
        images = bs4.find_all('img', {})


scraper = ImageScraper(url="http://www.photobirdireland.com/garden-birds.html")
scraper.scrape_images() 

f = open('Users/Lu/Desktop/Images','wb') # folder 
f.write(img) 
f.close()

但是我没有得到任何结果或错误.

but I'm not getting any results or errors.

我很确定代码中有什么不起作用.

I'm pretty sure something's not working in the code.

请您看看，告诉我出什么问题了吗?

Can you have a look at it please and tell me what is wrong?

推荐答案

您的代码不完整，images = bs4.find_all('img', {})

示例

for image in images:
    # get the img url
    img_url = image.get('src').replace('\\', '/')
    real_url = "http://www.photobirdireland.com/" + img_url

    # get the image name
    img_name = str(img_url.split('/')[-1])

    # now download the image using - import urllib.request & import os
    print("downloading {}".format(img_url))
    urllib.request.urlretrieve(real_url, os.path.join(path, img_name))

---

完整代码应如下所示-

import os
import urllib.request
import requests
from urllib.request import urlopen
from bs4 import BeautifulSoup as Bs


class ImageScraper:
    def __init__(self, url, download_path):
        self.url = url
        self.download_path = download_path
        self.session = requests.Session()

    def scrape_images(self):
        path = self.download_path
        html = urlopen(self.url)
        bs4 = Bs(html, 'html.parser')
        images = bs4.find_all('img', {})

        for image in images:
            # get the img url
            img_url = image.get('src').replace('\\', '/')
            real_url = "http://www.photobirdireland.com/" + img_url
            print(real_url)
            # get the image name
            img_name = str(img_url.split('/')[-1])
            print(img_name)
            print("downloading {}".format(img_url))
            urllib.request.urlretrieve(real_url, os.path.join(path, img_name))


scraper = ImageScraper(
    url="http://www.photobirdireland.com/garden-birds.html", download_path=r"D:\Temp\Images")
scraper.scrape_images()
