Question

我正在编写这个 Django 程序，它是 Craigslist 的克隆，但显示了搜索到的产品的图像。问题是我无法在卡片上显示实际图像，我只能在卡片的左上角看到图像图标

 import requests
from bs4 import BeautifulSoup
from django.shortcuts import render
from urllib.parse import quote_plus
from . import models



BASE_CRAIGSLIST_URL = 'https://losangeles.craigslist.org/d/services/search/bbb?query={}'
BASE_IMAGE_URL = 'https://images.craigslist.org/{}_300x300.jpg'

# Create your views here.
def home(request):
    return render(request, 'base.html')


def new_search(request):
    search = request.POST.get('search')
    models.Search.objects.create(search=search)
    final_url = BASE_CRAIGSLIST_URL.format(quote_plus(search))
    response = requests.get(final_url)
    data = response.text
    soup = BeautifulSoup(data, features='html.parser')

    post_listings = soup.find_all('li', {'class': 'result-row'})

    final_postings = []

    for post in post_listings:
        post_title = post.find(class_='result-title').text
        post_url = post.find('a').get('href')

        if post.find(class_='result-price'):
            post_price = post.find(class_='result-price').text
        else:
            post_price = 'N/A'

        if post.find(class_='result-image').get('data-ids'):
            post_image_id = post.find(class_='result-image').get('data-ids').split(',')[0].split(':')
            post_image_url = BASE_IMAGE_URL.format(post_image_id)
            print(post_image_url)
        else:
            post_image_url = 'https://craigslist.org/images/peace.jpg'

        final_postings.append((post_title, post_url, post_price, post_image_url))


    stuff_for_frontend = {
        'search': search,
        'final_postings': final_postings,
    }
    return render(request, 'my_app/new_search.html', stuff_for_frontend)

Answer 1

所以我想通了，我试图访问单个图像，但 url 就像一张图像幻灯片，所以我不得不选择第一张图像并像这样显示那个

post_image_id = post.find(class_='result-image').get('data-ids').split(',')[0].split(':')[1]

无法显示图像
