由这篇博文启发，我们可以通过 GitHub 的工作流让代码跑在 GitHub 上，并将获得的数据存在仓库中。
首先是写 Python 脚本，这部分比较简单。不难找到几个关键的请求链接 https://www.cnblogs.com/XuYueming/ajax/GetPostStat，/blog-stats，/news，/sidecolumn.aspx，用 requests 请求后用 BeautifulSoup 解析即可。然后通过 json 保存下来。
import requests
import json
from datetime import datetime, UTC
from pathlib import Path
from bs4 import BeautifulSoupBASE_URL = "https://www.cnblogs.com/XuYueming/ajax"
OUTPUT_PATH = Path("data")
INTERESTED_BLOGS = [18313014, 18397758]def fetch_html(url: str) -> BeautifulSoup:resp = requests.get(url, timeout=10)resp.raise_for_status()return BeautifulSoup(resp.text, "html.parser")def extract_int_by_id(soup: BeautifulSoup, element_id: str) -> int:el = soup.find(id=element_id)if not el:return 0text = el.get_text(strip=True)digits = "".join(ch for ch in text if ch.isdigit())return int(digits) if digits else 0def fetch_blog_info(blog_ids: list[int]) -> dict:resp = requests.post(f'{BASE_URL}/GetPostStat',data=json.dumps(blog_ids),headers={"Content-Type": "application/json; charset=utf-8"})resp.raise_for_status()return resp.json()def fetch_blog_stats() -> dict:soup = fetch_html(f"{BASE_URL}/blog-stats")return {"post_count": extract_int_by_id(soup, "stats_post_count"),"article_count": extract_int_by_id(soup, "stats_article_count"),"comment_count": extract_int_by_id(soup, "stats-comment_count"),"view_count": extract_int_by_id(soup, "stats-total-view-count"),}def fetch_news() -> dict:soup = fetch_html(f"{BASE_URL}/news")profile_div = soup.find(id="profile_block")if not profile_div:return {"nickname": "", "join_age": "", "fans": 0, "follow": 0}a_tags = profile_div.find_all("a")nickname = a_tags[0].get_text(strip=True) if len(a_tags) > 0 else ""join_age = a_tags[1].get_text(strip=True) if len(a_tags) > 1 else ""fans_tag = profile_div.find("a", class_="follower-count")fans = int(fans_tag.get_text(strip=True)) if fans_tag and fans_tag.get_text(strip=True).isdigit() else 0follow_tag = profile_div.find("a", class_="folowing-count")follow = int(follow_tag.get_text(strip=True)) if follow_tag and follow_tag.get_text(strip=True).isdigit() else 0return {"nickname": nickname,"join_age": join_age,"fans": fans,"follow": follow}def fetch_sidecolumn() -> dict:soup = fetch_html(f"{BASE_URL}/sidecolumn.aspx")data = {}# recent_posts = []# ul = soup.select_one("#sidebar_recentposts ul")# if ul:# for li in ul.find_all("li"):# a = li.find("a")# if a:# recent_posts.append({"title": a.get_text(strip=True), "link": a.get("href")})# data["recent_posts"] = recent_posts# tags = []# ul = soup.select_one("#sidebar_toptags ul")# if ul:# for li in ul.find_all("li"):# a = li.find("a")# if a and "更多" not in a.get_text():# count_span = li.find("span", class_="tag-count")# count = int(count_span.get_text(# strip=True).strip("()")) if count_span else 0# tags.append({# "name": a.get_text(strip=True).replace(f"({count})", ""),# "count": count,# # "link": a.get("href")# })# data["tags"] = tags# collections = []# for div in soup.select("#sidebar_categories .catList"):# title = div.select_one(".catListTitle")# if title:# title_text = title.get_text(strip=True).split("(")[0]# items = []# for a in div.select("ul li a"):# items.append({"name": a.get_text(strip=True), "link": a.get("href")})# collections.append({"title": title_text, "items": items})# data["collections"] = collections# archives = []# archive_div = soup.select_one("#sidebar_postarchive ul")# if archive_div:# for a in archive_div.find_all("a"):# archives.append({"name": a.get_text(strip=True), "link": a.get("href")})# data["archives"] = archives# recent_comments = []# comment_block = soup.select_one("#sidebar_recentcomments .RecentCommentBlock ul")# if comment_block:# items = comment_block.find_all(recursive=False)# for i in range(0, len(items), 3):# title_li = items[i]# body_li = items[i + 1] if i + 1 < len(items) else None# author_li = items[i + 2] if i + 2 < len(items) else None# if title_li and body_li and author_li:# a = title_li.find("a")# title = a.get_text(strip=True) if a else ""# link = a.get("href") if a else ""# content = body_li.get_text(strip=True)# author = author_li.get_text(strip=True).lstrip("--")# recent_comments.append({"title": title, "link": link, "content": content, "author": author})# data["recent_comments"] = recent_commentsscore_rank = {}ul = soup.select_one("#sidebar_scorerank ul")if ul:score_li = ul.find("li", class_="liScore")rank_li = ul.find("li", class_="liRank")score = int("".join(ch for ch in score_li.get_text()if ch.isdigit())) if score_li else 0rank = int("".join(ch for ch in rank_li.get_text()if ch.isdigit())) if rank_li else 0score_rank = {"score": score, "rank": rank}data["score_rank"] = score_rankreturn datadef main():snapshot = {"fetched_at": datetime.now(UTC).isoformat() + "Z","blog_stats": fetch_blog_stats(),"news": fetch_news(),"sidecolumn": fetch_sidecolumn(),"interested_blogs:": fetch_blog_info(INTERESTED_BLOGS)}OUTPUT_PATH.mkdir(exist_ok=True)timestamp = datetime.now(UTC).strftime("%Y%m%d_%H%M%S")output_file = OUTPUT_PATH / f"cnblogs_snapshot_{timestamp}.json"with open(output_file, "w", encoding="utf-8") as f:json.dump(snapshot, f, ensure_ascii=False, indent=2)print("blog snapshot saved:", output_file)if __name__ == "__main__":main()
保存的 json 长这样：
{"fetched_at": "2025-11-26T14:07:43.823701+00:00Z","blog_stats": {"post_count": 130,"article_count": 0,"comment_count": 76,"view_count": 10033},"news": {"nickname": "XuYueming","join_age": "1年9个月","fans": 24,"follow": 5},"sidecolumn": {"score_rank": {"score": 12067,"rank": 111361}},"interested_blogs:": [{"postId": 18313014,"viewCount": 704,"feedbackCount": 1,"diggCount": 10,"buryCount": 0},{"postId": 18397758,"viewCount": 1080,"feedbackCount": 15,"diggCount": 11,"buryCount": 0}]
}
然后我们要通过 GitHub workflow 进行上传到仓库，新建 .github/workflows/fetch_blog_stats.yml，里面就可以自定义流程了：
name: Fetch Blog Statson:workflow_dispatch:schedule:- cron: '0 0 * * *'jobs:run-python:runs-on: ubuntu-lateststeps:- name: Checkout repositoryuses: actions/checkout@v3with:persist-credentials: true- name: Set up Pythonuses: actions/setup-python@v4with:python-version: '3.11'- name: Install dependenciesrun: |python -m pip install --upgrade pippip install -r requirements.txt- name: Run Python scriptrun: python scripts/fetch_blog_stats.py- name: Commit and push changesrun: |git config --global user.name "github-actions[bot]"git config --global user.email "github-actions[bot]@users.noreply.github.com"git add data/git commit -m "chore: auto-update by workflow" || echo "No changes to commit"git push origin HEAD
不要忘记在 settings 里把 Workflow permissions 改成 Read and write permissions，第一次忘开导致工作流失败了。
然后就结束了，可以在我的 github 仓库查看，该项目在 MIT 协议下开源。
