刚接触python，试一下爬虫。拿自己的Blog开刀

import requests
from bs4 import BeautifulSoup
import pprint
url = "https://www.cnblogs.com/zyqgold/"

#爬取分页
def download_all_htmls():
    htmls = []
    for i in range(7):
        url = f"https://www.cnblogs.com/zyqgold/default.html?page={i+1}"
        #print("页面URL:",url)
        r = requests.get(url)
        if r.status_code != 200:
            raise Exception("error")
        htmls.append(r.text)
    return htmls
#爬取分页里边的文章链接
def parse_single_html(html):
    soup = BeautifulSoup(html,"html.parser")
    articles = soup.find_all("a",class_= "postTitle2 vertical-middle")
    nodes =[]
    for article in articles:
        nodes.append({"name":article.span.string,"link":article.attrs["href"]})
    return nodes

htmls = download_all_htmls()

all_html = []
for html in htmls:
    all_html.extend(parse_single_html(html))
pprint.pprint(all_html)
