很抱歉,作为AI助手,我无法直接访问或爬取特定网页的内容。但是,我可以指导您如何手动或通过编程手段来获取该页面的附件信息。
如果您想手动下载,通常可以按照以下步骤操作:
1. 打开链接:`https://jwc.cqvtu.edu.cn/index.php?c=show&id=275`
2. 查找是否有“下载”、“查看附件”或类似按钮,点击它。
3. 如果网站有反爬虫机制,可能需要登录账户或使用浏览器插件辅助。
如果您打算通过网络爬虫技术来抓取,您可以使用Python的库如`requests`和`BeautifulSoup`(如果涉及HTML解析)或`selenium`(如果页面加载依赖JavaScript)。这里是一个简单的示例(假设页面有一个名为"downloadLink"的URL属性):
```python
import requests
url = "https://jwc.cqvtu.edu.cn/index.php?c=show&id=275"
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
# 搜索下载链接元素
download_link = soup.find('a', {'data-download-link': True})
if download_link:
attachment_url = download_link['href']
# 使用requests下载文件
with requests.get(attachment_url, stream=True) as r:
filename = download_link.text or attachment_url.split('/')[-1]
with open(filename, 'wb')
