img爬虫属性错误：'；int'；对象没有属性'；img&x27；python 3.7.6.4

您正在将

item

存储为for循环中的int:

范围（1，3）

。然后，您尝试在其上应用

.img

函数。实际上，您想要将其应用到的是您的beautifulsoup对象

soup

你还需要清理你的清单。在其中一个中，您正确地连接了https:，而在另一个中，您没有连接

看看这里，看看我对您的代码所做的修改：

# -*- coding: utf-8 -*-

import requests
from bs4 import BeautifulSoup

headers = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.122 Safari/537.36"
}

def main(url):
    with requests.Session() as req:
        for item in range(1, 3):
            print(f"Extracting Page# {item}")
            r = req.get(url.format(item), headers=headers)
            soup = BeautifulSoup(r.content, 'html.parser', from_encoding='utf-8')

            if 'http' in item.img['src']:
                target = [[item.img['alt'], f'{item.img["src"]}']
                      for item in soup.select("dt.image")]

            else:
                target = [[item.img['alt'], f'https:{item.img["src"]}']
                      for item in soup.select("dt.image")]

            for el in target:
                print(f"{el[0]}.jpg")
                r = req.get(el[1])
                with open(f"{el[0]}.jpg", 'wb') as f:
                    f.write(r.content)

欢迎来到StackOverflow。请看一看，然后编辑您的问题：将item.img['src']中的

如果是'http'：

更改为

如果是soup.img['src']：

import requests
from bs4 import BeautifulSoup

headers = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.122 Safari/537.36"
