抓取本地加载的图像

Question

我正在学习 Beautiful Soup，但在尝试抓取从本地目录上传的图像时运行遇到了问题。我看到的错误是：

ValueError: unknown url type: 'images/ixa2.png'

我假设发生的情况是图像是从本地目录加载的，而不是通过 URL 托管的。这就是我检查要抓取的元素时的样子：

<img width="200" align="left" hspace="0" src="ixa/cards/axisofmortality.jpg">

我很好奇是否可以抓取这些图像，如果可以，如何抓取。

这是我正在使用的代码：

from urllib import request
import urllib.request
from bs4 import BeautifulSoup as soup

def make_soup(url):
    result = request.urlopen(url)
    page = result.read()

    parsed_page = soup(page, "html.parser")
    result.close()
    return parsed_page

def get_images(url):
    soup = make_soup(url)
    images = [img for img in soup.findAll('img')]
    print (str(len(images)) + "images found.")
    print('Downloading images to current working directory.')
    #compile our unicode list of image links
    image_links = [each.get('src') for each in images]
    for each in image_links:
        filename=each.split('/')[-1]
        urllib.request.urlretrieve(each, filename)
    return image_links

get_images('http://mythicspoiler.com/')

您正在尝试从不完整的 url 下载图像。

我的建议是这样的：

def get_images(url):
    soup = make_soup(url)
    images = [img for img in soup.findAll('img')]
    print (str(len(images)) + "images found.")
    print('Downloading images to current working directory.')
    #compile our unicode list of image links
    image_links = [each.get('src') for each in images]
    for each in image_links:
        filename=each.split('/')[-1]
        urllib.request.urlretrieve('http://mythicspoiler.com/' + each, filename) # <---
    return image_links
