我是新手，只是想从lol site逃脱所有charackterportraits，当我在浏览器中查看其中一张图片时，它位于“ img scr =“ url”标签中，我想获取下载图片的URL，但是当我做汤.select（'img [src]'）或汤.select（'img'）时，它返回一个空列表，我不知道为什么
代码如下：
data=requests.get(website)
data.raise_for_status()
soup = bs4.BeautifulSoup(data.text,"lxml")
print(soup)
#soup returns html
elems = soup.select('img[src]')
print(elems)
#elems returns an empty list

可能可以处理请求，但是您的get请求似乎未获取完整的pageSource。
您可以使用硒来克服此问题，只需获取内容即可。
from selenium import webdriver
import bs4
driver = webdriver.Chrome()
driver.get('https://na.leagueoflegends.com/en/game-info/champions/')
page_source = driver.page_source
driver.close()
soup = bs4.BeautifulSoup(page_source, "lxml")
print(soup)
elems = soup.find_all('img')
for elem in elems:
print(elem.attrs['src'])
输出：

使用与页面相同的端点。在“网络”标签中找到它
public ActionResult Create()
{
ViewBag.Types = new SelectList(db.Types.ToList(), "Id", "Name");
return View();
}
@Html.DropDownListFor(model => model.Type, (SelectList)ViewBag.Types, new { @class = "form-control"})
