无法使用漂亮的汤和python刮取图像URL。

Question

因此，基本上，我使用下面的代码从explore_more_url变量中的各个链接中刮取信用卡的图像urls。

from urllib.request import urlopen
from bs4 import BeautifulSoup
import json, requests, re
from selenium import webdriver

driver = webdriver.Chrome(executable_path="C:\\Users\\Hari\\Downloads\\chromedriver.exe")

img_url = []

explore_more_url = ['https://www.axisbank.com/retail/cards/credit-card/axis-bank-ace-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/axis-bank-aura-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/privilege-easy-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/reserve-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/axis-bank-freecharge-plus-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/indianoil-axis-bank-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/axis-bank-magnus-card/feature-benefits', 'https://www.axisbank.com/retail/cards/credit-card/flipkart-axisbank-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/axis-bank-freecharge-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/my-zone-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/neo-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/axis-bank-vistara-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/axis-bank-vistara-signature-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/axis-bank-vistara-infinite-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/privilege-credit-card-with-unlimited-travel-benefits-account', 'https://www.axisbank.com/retail/cards/credit-card/miles-more-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/axis-bank-select-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/pride-platinum-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/pride-signature-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/my-zone-easy-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/insta-easy-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/signature-credit-card-with-lifestyle-benefits', 'https://www.axisbank.com/retail/cards/credit-card/platinum-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/titanium-smart-traveler-credit-card', 'https://www.axisbank.com/retail/cards/credit-card/my-wings-credit-card/features-benefits']

for x in explore_more_url:
    driver.get(x)
    soup_1 = BeautifulSoup(driver.page_source, 'lxml')
    img_url.append("https://www.axisbank.com" + soup_1.find('img', alt="Fast Forward Banner").get('src'))

print(img_url)

输出:

Traceback (most recent call last):
 File "C:\Users\Hari\PycharmProjects\Card_Prj\axis.py", line 82, in <module>
   img_url.append("https://www.axisbank.com" + soup_1.find('img', alt="Fast Forward Banner").get('src'))
AttributeError: 'NoneType' object has no attribute 'get'

每个链接中的图像都是这样的：

​

我可以使用的适当代码是什么，这样我就可以准确地得到我期望的东西了？

Answer 1

获取图像的一种方法可能是：

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/55.0.2883.87 Safari/537.36'
}
page = requests.get("https://www.axisbank.com/retail/cards/credit-card/axis-bank-ace-credit-card", headers=headers).text
img_src_ = BeautifulSoup(page, "html.parser").select_one('.bannerWrapper img')["src"]

with open(img_src_.rsplit("/")[-1], "wb") as image:
    image.write(requests.get(f"https://www.axisbank.com{img_src_}").content)

输出:脚本本地目录中的.jpg文件

ace-product-landing-web-version-1920x360.jpg

编辑:要获得源urls，请尝试如下：

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/55.0.2883.87 Safari/537.36'
