python 图片抓取工具，无法在 bing 上正常工作

Question

我正在尝试构建图像抓取工具，我首先尝试 Google 但没有图像被抓取所以我尝试了 Bing 并且成功了，但是有一些问题

被抓取的图片链接只是显示内容的一小部分在搜索引擎中。
Scraped 图片来自预览中的未知页面。
图像在安全模式过滤器中默认被抓取。

我想抓取 bing 中显示的所有图像（或某些页面）。com/images/search 但它做的很少。

检查后我发现图像链接存储在 'thumb' class 中 bing 所以我 删除了 所有有拇指的链接class, 但看起来还不够。

在查看源代码后，只有拇指 class 链接被发现实际上最后有 .jpg

import requests
from bs4 import BeautifulSoup
import os
import random
from urllib.parse import urljoin


url = "https://www.bing.com"

search = input("enter the search term: ")
r = requests.get(url + "/images/search", params={"q":search})

soup = BeautifulSoup(r.content,"html.parser")

li = soup.find_all("a",class_="thumb")

# getting links from thumb class  

links = [l.get("href") for l in li]


print("{0} results found with the search term: {1}".format(len(links), search))
choice = input("Do You Want To Extract The Images? Y or N ")
dir_name = "Result"

# Creating the Result named directory if it didn't existed
if os.path.isdir(dir_name) == False:
    print("[+] Creating Directory Named '{0}'".format(dir_name))
    os.mkdir(dir_name)
    
n = 1
if(choice == 'Y' or choice == 'y'):
    for i in links:
        req = requests.get(i)

        #title = links[z].split("/")[-1]
        #there were some issues with the default titles so I instead used names generated by
        #random sequence

        print("[+] Extracting Image #",n)
        with open(("{0}/" + generateRandomSequence() + ".jpg").format(dir_name),"wb") as img:
            img.write(req.content)
        n += 1

  #for generating random sequence
def generateRandomSequence():
    seq = ""
    letters = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z",
               "A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z",
                ]
    for i in range(0,5):
        seq = seq + random.choice(letters) + str(random.randrange(1,1000))
    
    return seq

这是给你的一个刮痕：

import requests
from bs4 import BeautifulSoup
seartext = input("enter the search term: ")
count = input("Enter the number of images you need:")
adlt = 'off' # can be set to 'moderate'
sear=seartext.strip()
sear=sear.replace(' ','+')
URL='https://bing.com/images/search?q=' + sear + '&safeSearch=' + adlt + '&count=' + count
print(URL)
USER_AGENT = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:65.0) Gecko/20100101 Firefox/65.0"
headers = {"user-agent": USER_AGENT}
resp = requests.get(URL, headers=headers)
results=[]
soup = BeautifulSoup(resp.content, "html.parser")
print(soup)
wow = soup.find_all('a',class_='iusc')
for i in wow:
    try:
        print(eval(i['m'])['murl'])
        print()
    except:
        pass
