Hello Community是python的初学者,他希望创建一个工具来部分地获得生命。我制作了这个小代码,作为页面的img标记进行过滤

import requests 
from bs4 import BeautifulSoup 
    t=input('Digite o Nome do Filme:') 
    ano=int(input('Digite o Ano do Filme:')) 

if ano==1:
  req=requests.get('https://www.themoviedb.org/search?query='+t+'&language=pt-BR')
  bs=BeautifulSoup(req.text, 'lxml') 
  print(bs.find_all('img')) 
else:
  req=requests.get('https://www.themoviedb.org/search?query='+t+'%20y%3A'+str(ano)+'&language=pt-BR')
  bs=BeautifulSoup(req.text, 'lxml') 
  print(bs.find_all('img')) 
然后我做了另一个部分,获取图像链接并将其显示在控制台上

import io
import os
import requests
import tempfile
from PIL import Image
from matplotlib import pyplot as plt

img_url = 'https://image.tmdb.org/t/p/w500_and_h282_face/dKxkwAJfGuznW8Hu0mhaDJtna0n.jpg'

buffer = tempfile.SpooledTemporaryFile(max_size=1e9)
r = requests.get(img_url, stream=True)
if r.status_code == 200:
    downloaded = 0
    filesize = int(r.headers['content-length'])
    for chunk in r.iter_content():
        downloaded += len(chunk)
        buffer.write(chunk)
        print(downloaded/filesize)
    buffer.seek(0)
    i = Image.open(io.BytesIO(buffer.read()))
    i.save(os.path.join('.', 'image.jpg'), quality=85)
buffer.close() 

plt.imshow(i)
plt.show() 

因此,我想知道如何使img_url变量自动获取打印url(bs.find_all('img'))。或者如果有库的话。

我在你的第一个代码中做了一个修改,现在你可以使用“poster fade lazyautosizes lazyloaded”类访问每个标签img的链接。我建议你把第二个代码放进去 函数,然后在此脚本中调用它

import requests
from bs4 import BeautifulSoup

t=input('Digite o Nome do Filme:')
ano=int(input('Digite o Ano do Filme:'))

if ano==1:
  req=requests.get('https://www.themoviedb.org/search?query='+t+'&language=pt-BR')
  bs=BeautifulSoup(req.text, 'lxml')
  #elements=bs.find_all('img',class_="fade lazyautosizes lazyloaded")
  elements=bs.select('div.image_content > a > img')
  for element in elements:
      print("LINK")
      print (element['data-src'])
      #Here should put a function for pass the url to script matplotlib 
      myfunctionmatplotlib(element['data-src'])  
else:
  req=requests.get('https://www.themoviedb.org/search?query='+t+'%20y%3A'+str(ano)+'&language=pt-BR')
  bs=BeautifulSoup(req.text, 'lxml')
  elements=bs.select('div.image_content > a > img')
  for element in elements:
      print("LINK")
      print (element['data-src'])
      #Here should put a function for pass the url to script matplotlib 
      myfunctionmatplotlib(element['data-src'])

我编写了这段新代码,您可以尝试下载URL的图像。我还编写了一个代码,可以从关键字中获取图像的URL,如果这能解决您的问题,我可以与您共享该代码:
