在Python中获取URL的方法有多种,以下是一些常用的方法:
1. 使用`requests`库:
import requests
url = 'https://example.com/'
response = requests.get(url)
print(response.url) 输出URL
2. 使用`BeautifulSoup`库解析HTML内容:
from bs4 import BeautifulSoup
import requests
url = 'https://example.com/'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
for link in soup.find_all('a'):
print(link.get('href')) 输出每个链接的URL
3. 使用`urllib`库:
from urllib.request import urlopen
from bs4 import BeautifulSoup
url = 'https://example.com/'
html = urlopen(url).read()
soup = BeautifulSoup(html, 'html.parser')
for link in soup.find_all('a', href=True):
print(link['href']) 输出每个链接的URL
4. 使用正则表达式匹配URL:
import re
text = 'This is a URL: https://example.com'
urls = re.findall(r'https?://[^\s]+', text) 输出匹配到的URL
5. 使用`Selenium`库获取动态网页的URL:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://example.com/')
print(driver.current_url) 输出当前URL
以上方法可以帮助你在Python中获取URL。如果你需要处理相对URL并将其转换为绝对URL,可以使用`urljoin`函数:
from urllib.parse import urljoin
base_url = 'https://example.com/'
relative_url = '/path/to/page'
absolute_url = urljoin(base_url, relative_url)
print(absolute_url) 输出绝对URL
请根据你的具体需求选择合适的方法
