python - 使用 BeautifulSoup 在 Python 中循环遍历 Href

Question

所以我试图从此链接中提取所有文章 URL。
但是我只得到 ['https://mn.usembassy.gov/mn/2020-naadam-mn/', 'https://mn.usembassy.gov/mn/06272020-presidential-proclamation-mn/', 'https://mn.usembassy.gov/mn/pr-060320-mn/', 'https://mn.usembassy.gov/mn/dv-2021-status-check-mn/', 'https://mn.usembassy.gov/mn/pr-050120-mn/']下面是我目前的代码。
该网站有 52 个页面，我正在尝试获取所有 URL，为什么它只给我几个 URL 而不是所有 URL？

import requests
from bs4 import BeautifulSoup
url = 'https://mn.usembassy.gov/mn/news-events-mn/'
reqs = requests.get(url)
soup = BeautifulSoup(reqs.text, 'lxml')

urls = []
for h in soup.find_all('h2'):
    a = h.find('a')
    urls.append(a.attrs['href'])
print(urls)

Answer 1

该页面仅包含 5 个文章链接，您需要转到下一页才能加载接下来的 5 个链接。此脚本将从页面中获取所有链接:

import requests
from bs4 import BeautifulSoup


url = 'https://mn.usembassy.gov/mn/news-events-mn/page/{page}/'

urls = []
for page in range(1, 53):
    soup = BeautifulSoup(requests.get(url.format(page=page)).content, 'html.parser')
    for h in soup.find_all('h2'):
        a = h.find('a')
        print(a['href'])
        urls.append(a.attrs['href'])


from pprint import pprint
pprint(urls)

打印:
