关于如何把markdown转化成html
1.首先是配置
md.py文件：
import os
import time
import markdown
from lib.log import logging
MD_FOLDER = "static/md"
HTML_FOLDER = "html/md_content"
if not os.path.exists(HTML_FOLDER):
os.mkdir(HTML_FOLDER)
def need_update(md_fp, html_fp):
if not os.path.exists(html_fp):
return True
if os.stat(md_fp).st_ctime > os.stat(html_fp).st_mtime:
return True
return False
def makesure_html_exists(filename, folder=""):
logging.debug(f"convert: {filename} in {folder}")
md_fp = os.path.join(MD_FOLDER, folder, f"{filename}.md")
html_fp = os.path.join(HTML_FOLDER, folder, f"{filename}.html")
if need_update(md_fp, html_fp):
logging.debug(f"convert: {md_fp} --> {html_fp} ing")
markdown.markdownFromFile(input=md_fp, output=html_fp, encoding="utf-8", extensions=["toc", "tables"])
logging.info(f"convert: {md_fp} --> {html_fp}")
log.md文件：
import os
import logging
LOG_FOLDER = "../log"
if not os.path.exists(LOG_FOLDER):
os.mkdir(LOG_FOLDER)
LOG_FORMAT = "[%(asctime)s] [%(levelname)s] %(message)s"
DATE_FORMAT = "%Y/%m/%d %H:%M:%S %p"
logging.basicConfig(level=logging.DEBUG, format=LOG_FORMAT, datefmt=DATE_FORMAT)
logging.debug("debug log")
logging.info("info log")
logging.warning("warning log")
logging.error("error log")
logging.critical("critical log")

return True, "Login", make_token(username)
else:

def is_alive(ts):

return (dt_now - dt).seconds < TOKEN_ALIVE_TIMEINTERVAL

if value and is_alive(value["timestamp"]):
return value["username"]
return None

def get_auth_status(cookies):

logging.info(f"get_auth_status() out: {status_comment[content['status']]}, content={content}")
return content
main.py文件
from flask import request, Flask, render_template, redirect
from lib.md import makesure_html_exists
from lib.log import logging
from lib.auth import get_auth_status, do_the_login, do_the_logout

@main.route("/login", methods=["POST"])
def login():
"""

"""
username = request.form["nick_name"]
password = request.form["password"]
status, action, token = do_the_login(username, password)
resp = redirect(request.referrer)
resp.set_cookie("status", str(status))
resp.set_cookie("action", action)
resp.set_cookie("token", token)
return resp
@main.route("/logout", methods=["POST"])
def logout():
"""

token = request.cookies.get("token", None)
do_the_logout(token)
resp = redirect(request.referrer)
resp.delete_cookie("status")
resp.delete_cookie("action")
resp.delete_cookie("token")
return resp
2.如何转化
首先先创个md文件，内容根据markdown格式来
然后在main.py文件中插入@main.route指令
会自动生成一个html文件，而这个html文件显示的内容就是markdown转化而成的
在模版中插入 {% include "md_content/"+filename+".html" %}就相当于把markdown转化成html的内容放到这里
