fask session
名为 session 的对象，它允许你在几个请求间存储特定于用户的信息。它基于 cookie 实现，并对 cookie 进行加密签名。这意味着用户可以查看你的 cookie 内容，但无法修改，除非他们知道用于签名的密钥

源码
from flask import Blueprint, request, session, redirect, url_for
bp = Blueprint('session', __name__, url_prefix='/api/test')
# Set the secret key to some random bytes. Keep this really secret!
secret_key = b'_5#y2L"F4Q8z\n\xec]/'
@bp.route('/testU', methods=['GET', 'POST'])
def index():
if 'username' in session:
return f'Logged in as {session["username"]}'
return 'You are not logged in'
@bp.route('/login', methods=['GET', 'POST'])
def login():
if request.method == 'POST':
session['username'] = request.form['username']
return redirect(url_for('index'))
return '''
<form method="post">
<p><input type=text name=username>
<p><input type=submit value=Login>
</form>
'''
@bp.route('/logout')
def logout():
# remove the username from the session if it's there
session.pop('username', None)
return redirect(url_for('index'))
