如何从BeautifulSoup下载图片？

Question

图片http://i.imgur.com/OigSBjF.png

导入请求从 bs4 导入 BeautifulSoup</p> <pre>r = requests.get("xxxxxxxxx") soup = BeautifulSoup(r.content) for link in links: if "http" in link.get('src'): print link.get('src')

我得到打印出来的 URL 但不知道如何使用它。

Answer 1

您需要下载并写入磁盘：

import requests
from os.path  import basename

r = requests.get("xxx")
soup = BeautifulSoup(r.content)

for link in links:
    if "http" in link.get('src'):
        lnk = link.get('src')
        with open(basename(lnk), "wb") as f:
            f.write(requests.get(lnk).content)

您还可以使用 select 来过滤您的标签，只获取带有 http 链接的标签：

for link in soup.select("img[src^=http]"):
        lnk = link["src"]
        with open(basename(lnk)," wb") as f:
            f.write(requests.get(lnk).content)

Answer 2

虽然其他答案完全正确。

我发现下载真的很慢，而且不知道高分辨率图片的进度。

所以，做了这个。

from bs4 import BeautifulSoup
import requests
import subprocess

url = "https://example.site/page/with/images"
html = requests.get(url).text # get the html
soup = BeautifulSoup(html, "lxml") # give the html to soup

# get all the anchor links with the custom class 
# the element or the class name will change based on your case
imgs = soup.findAll("a", {"class": "envira-gallery-link"})
for img in imgs:
    imgUrl = img['href'] # get the href from the tag
    cmd = [ 'wget', imgUrl ] # just download it using wget.
    subprocess.Popen(cmd) # run the command to download
    # if you don't want to run it parallel;
    # and wait for each image to download just add communicate
    subprocess.Popen(cmd).communicate()

警告：它不适用于 win/mac，因为它使用 wget。

奖励：如果您没有使用通信，您可以看到每个图像的进度。
