如何从链接中获取文本并进行裁剪？

import requests
from bs4 import BeautifulSoup

def fetch_text_from_url(url):
    try:
        response = requests.get(url)
        response.raise_for_status()  # 检查请求是否成功
        soup = BeautifulSoup(response.text, 'html.parser')
        text = soup.get_text()  # 获取所有文本内容
        return text
    except requests.RequestException as e:
        print(f"Error fetching the URL: {e}")
        return None

def crop_text(text, max_length):
    if len(text) > max_length:
        return text[:max_length] + "..."
    return text

# 示例使用
url = "https://example.com/some-article"
text = fetch_text_from_url(url)
if text:
    cropped_text = crop_text(text, 100)  # 裁剪到100个字符
    print(cropped_text)
