导入请求从 bs4 导入 BeautifulSoup

import requests from bs4 import BeautifulSoup

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

for link in links:
    if "http" in link.get('src'):
       print link.get('src')

推荐答案

您需要下载并写入磁盘:

You need to download and write to disk:

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 来过滤您的标签以仅获取带有 http 链接的标签:

You can also use a select to filter your tags to only get the ones with http links:

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