使用python抓取網站並收集所有超鏈接

Question

我正在制作一個可以從任何網站獲取信息的程序。 但該程序不起作用。

示例——網站是 naukri.com，我們必須收集頁面的所有超鏈接：

import urllib.request, urllib.parse, urllib.error
from bs4 import BeautifulSoup
import ssl

isc = ssl.create_default_context()
isc.check_hostname = False
isc.verify_mode = ssl.CERT_NONE

open = urllib.request.urlopen('https://www.naukri.com/job-listings-Python- 
Developer-Cloud-Analogy-Softech-Pvt-Ltd-Noida-Sector-63-Noida-1-to-2-years-250718003152src=jobsearchDesk&sid=15325422374871&xp=1&px=1&qp=python%20developer 
&srcPage=s', context = isc).read()
soup = BeautifulSoup(open, 'html.parser')

tags = soup('a')

for tag in tags:
    print(tag.get('href', None))

Answer 1

我會使用請求和 bs4。 我能夠讓它發揮作用，我認為它具有預期的結果。 嘗試這個：

import requests
from bs4 import BeautifulSoup

url = ('https://www.naukri.com/job-listings-Python-Developer-Cloud-Analogy-Softech-Pvt-Ltd-Noida-Sector-63-Noida-1-to-2-years-250718003152src=jobsearchDesk&sid=15325422374871&xp=1&px=1&qp=python%20developer&srcPage=s')
response = requests.get(url)
page = response.text
soup = BeautifulSoup(page, 'html.parser')
links = soup.find_all('a', href=True)

for each in links:
    print(each.get('href'))
