python - 为什么我没有输出？

Question

我真的有一个非常简单的问题 - 为什么我没有得到输出？这是网站:https://riven.market/list/PC/Veiled .我认为问题是类名中的空格，但事实证明这是自然的，不会引起任何问题。如果您有任何问题，请在评论中告诉我

import requests
from bs4 import BeautifulSoup

r = requests.get("https://riven.market/list/PC/Veiled")

c = r.content

soup = BeautifulSoup(c, "html.parser")
all = soup.find_all("div", {"class":"riven-list" })
for item in all:
    print("Name" + item.find("div", {"class": "attribute weapon"}).text.replace("\n", "").replace(" ", ""))

Answer 1

这是我的解决方法，即查找查询将请求发送到的实际 URL。您可以通过右键单击-> inspect element -> network -> Find the get request

import requests
from bs4 import BeautifulSoup

# instead of sending to this
main = requests.get("https://riven.market/list/PC/Veiled")

ajax_url = "https://riven.market/_modules/riven/showrivens.php?baseurl=Lw==&platform=PC&limit=25&recency=-1&veiled=true&onlinefirst=true&polarity=all&rank=all&mastery=16&weapon=Any&stats=Any&neg=all&price=99999&rerolls=-1&sort=time&direction=ASC&page=1&time=1565851905857"
re = requests.get(ajax_url)
c = re.content

soup = BeautifulSoup(c, "html.parser")
all_divs = soup.find_all("div", class_ ="attribute weapon" )
for item in all_divs:
        print(item.text)

输出
