cookie
from flask import Flask, render_template, request, redirect, make_response
app = Flask(__name__)
user_list = ['wb', 'valentine', 'wb112232']
@app.route('/login/', methods=['GET','POST'])
def login():
if request.method == 'POST':
username = request.form['username']
if username in user_list:
response = make_response(redirect('/index/'))
response.set_cookie('username',value=username,max_age=300)
return response
else:
return redirect('/login/')
else:
return render_template('login.html')
@app.route('/index/')
def index():
username=request.cookies['username']
if username:
return render_template('index.html',username = username)
else:
return redirect('/login/')
if __name__ == '__main__':
app.debug = True
app.run()
response.setcookie('key', 'value', max_age=n) n的单位为秒。
response.cookies.get['name']/response.cookies['name']获取cookie
将max_age设置为0，即为删除cookie。
Session
生成一个
app.secret_key
import os res = os.urandom(24)
后台
from flask import Flask, render_template, request, redirect, session
app = Flask(__name__)
app.secret_key='x18x0b6x96xeaPx8d"xc8x04xf6Gx8exae5x0fxf6xe1x89xc1}x04xa3x0c'
user_list = ['wb', 'valentine', 'wb112232']
@app.route('/login/', methods=['GET','POST'])
def login():
if request.method == 'POST':
username = request.form['username']
if username in user_list:
session['username']=username
return redirect('/index/')
else:
return redirect('/login/')
else:
return render_template('login.html')
@app.route('/index/')
def index():
username=session['username']
if username:
return render_template('index.html',username = username)
else:
return redirect('/login/')
@app.route('/logout/')
def logout():
pass
if __name__ == '__main__':
app.debug = True
app.run()
cookie安全性差，session对服务器性能有影响，可将登陆信息存放于session
