我正在尝试制作从搜索关键字下载图像的网络抓取工具。该代码完全正常，直到它必须从提取的 URL 下载该图像
from bs4 import BeautifulSoup
import requests
import os
import urllib
search = raw_input("search for images: ")
params = {"q": search}
r = requests.get("http://wwww.bing.com/images/search", params=params)
dir_name = search.replace(" ", "_").lower()
if not os.path.isdir(dir_name):
os.makedirs(dir_name)
soup = BeautifulSoup(r.text, "html.parser")
links = soup.findAll("a", {"class": "thumb"})
for items in links:
img_obj = requests.get(items.attrs["href"])
print "Getting: ", items.attrs["href"]
title = items.attrs["href"].split("/")[-1]
urllib.urlretrieve(items.attrs["href"], "./scraped_images/")
输出：
search for images: cats
Getting: http://c1.staticflickr.com/3/2755/4353908962_2a0003aebf.jpg
Traceback (most recent call last):
File "C:/Users/qazii/PycharmProjects/WebScraping/exm.py", line 21, in <module>

您正在尝试将图像保存到名为./scraped_images/. 由于这是一个目录而不是文件，您会收到权限错误（您无法打开具有写权限的目录）。相反，请尝试保存为特定文件名。
urllib.urlretrieve(items.attrs["href"], os.path.join("./scrapped_images", title))
