爬虫爬取csdn博客信息并保存至本地形成xls表格的完整源代码

以下是一个Python爬虫，可以爬取CSDN博客信息并将其保存为Excel文件：

import requests
from bs4 import BeautifulSoup
import xlwt

url = "https://blog.csdn.net/"
user = "your_csdn_username"
user_url = url + user

response = requests.get(user_url)
soup = BeautifulSoup(response.text, "html.parser")

articles = soup.find_all("div", class_="article-item-box csdn-tracking-statistics")

# 创建Excel文件
workbook = xlwt.Workbook()
worksheet = workbook.add_sheet('CSDN Blog')

# 写入表头
worksheet.write(0, 0, 'Title')
worksheet.write(0, 1, 'Link')
worksheet.write(0, 2, 'Summary')

# 写入数据
row = 1
for article in articles:
    title = article.h4.a.text
    link = article.h4.a['href']
    summary = article.find("div", class_="article-desc").text.strip()
    worksheet.write(row, 0, title)
    worksheet.write(row, 1, link)
    worksheet.write(row, 2, summary)
    row += 1

# 保存Excel文件
workbook.save('csdn_blog.xls')

请将`your_csdn_username`替换为您自己的CSDN用户名，并确保已安装`requests`、`beautifulsoup4`和`xlwt`库。
