我正在尝试编写一个程序来刮除eBay以便向我展示产品清单，但是打印到终端上的所有内容都是“无”。我期待产品的标题。
我已将代码更改为“查找”不同的关键字，但是输出始终是相同的“无”，通常这意味着它找不到指定的关键字，但是我输入的关键字显示在网络上页面和“检查元素”中。
以下是代码段：
<nav class="navbar navbar-expand-sm navbar-menu navbar-inverse">
<div class="container-fluid">
<div class="row navbar-row">
<a class="navbar-brand hvr-glow" href="index.html" target="_blank">
<img src="../assets/images/the-who-name-logo.png" class="menu-text hvr-glow" width="90" height="90" padding="5px" alt="Logo">
</a>
<button class="navbar-toggler menu-button" data-toggle="collapse" data-target="#mainNav" aria-controls="navbar-collapse">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="mainNav">
<div class="navbar-nav list-inline-block">
<a class="nav-item nav-link hvr-glow menu-text" href="index.html" target="_blank">Home</a>
<a class="nav-item nav-link hvr-glow menu-text" href="media.html" target="_blank">Media</a>
<a class="nav-item nav-link hvr-glow menu-text" href="contact.html" target="_blank">Contact</a>
</div>
</div>
</div>
</div>
</nav>
</div>
我试图仅获取与我在程序中输入的关键字相对应的结果。
答案 0 :(得分：0)
可能选择器有误。我能够使用此代码从 eBay HTML 中提取标题。
from bs4 import BeautifulSoup
import requests
import os
params = {"_nkw": "coffee"}
headers = {
"User-Agent":
"Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36 OPR/66.0.3515.103"
}
proxies = {"http": os.getenv("PROXY_URL")}
# r = requests.get("https://www.ebay.com/sch/i.html", params=params, headers=headers, proxies=proxies)
# html = r.content
html = open("ebay.html", "r").read()
soup = BeautifulSoup(html, "lxml")
titles = [title.get_text() for title in soup.select("h3.s-item__title")]
print(titles)
输出
